Buying electronic components from a broker.
What happens between the warehouse and your line.

Buying electronic components from a broker is an ordinary week on this desk, and the reel that arrives has been through more hands than the packing list admits. Open-market distributors move somewhere between 10 and 15 percent of a semiconductor distribution market worth around 160 billion dollars, a share measured in July 2023 and no smaller now. Most buyers will feed brokered material to a line at some point in a product's life. What matters is what happened to that reel between somebody else's warehouse and your feeder, and how much of it you actually specified.

What does a broker do with your part before it ships?

What a broker does with your part before it ships depends entirely on whether the broker owns a warehouse, and the two models behave nothing alike. A pure broker never touches the hardware: it takes your RFQ, polls global inventory exchanges and its own network of EMS providers and distributors, matches you to a stockholder somewhere, and arranges a blind drop-shipment from that holder straight to your dock. The part's journey never passes through a broker facility, because there isn't one. What you gain is speed and reach. What you lose is in-house inspection, test data and, in most cases, any RMA route if the parts fail on your line.

A stocking independent distributor runs a different process. The lot is bought in, booked against a lot number, put into controlled storage and passed through an inspection station before it ships on to you. Parts out of an EMS surplus may be checked for solderability to J-STD-002 first, because leads that sat in a humid warehouse for four years don't always wet. Damaged trays get replaced. Reels get re-taped, or split and re-kitted to your quantity. By the time that lot reaches your dock it has been documented, photographed and repacked, and you should be able to read the sequence off the paperwork.

Know which of the two you are buying from before you argue about price. It decides where in the chain the inspection happens, and whether it happens at all.

Does an AS6081 certificate mean your lot was tested?

No. AS6081 is awarded at company level, and it confirms that the distributor operates a supplier qualification program, classifies incoming material by risk and maintains a counterfeit control plan. It certifies the process, never the reel. Buyers read the certificate as a testing guarantee constantly, and it isn't one.

The current revision makes this explicit by handing authentication testing to AS6171, which carries the laboratory test methods, the sampling plans and the pass/fail criteria. AS6081 sets a baseline: documentation and packaging review, general and detailed external visual inspection, radiological inspection to see the die and the bond wires, lead-finish analysis by XRF or EDS, and decapsulation on selected samples. Solvent tests catch remarking. Everything past that baseline happens because a purchase order said so.

So if you want X-ray on every date code, or decap on three units per lot, or electrical characterization at temperature, write AS6171 into your quality clauses and name the methods. Otherwise the honest description of what happened in that warehouse is: cartons opened, labels read, photographs taken, cartons closed. Our 10-step inspection in Malmö exists for the lots where that isn't enough, up to die-level decapsulation at x2145.

One part of AS6081 protects the market rather than your order. A suspect lot must be quarantined, investigated, dispositioned and reported to GIDEP and ERAI. It does not go back to the seller and it does not re-enter circulation. A distributor that quietly returns bad material to its supplier has put it in front of the next buyer.

How much counterfeit material is actually being found?

ERAI logged 1,055 suspect counterfeit and nonconforming parts in 2024, a 25 percent rise on the 786 reported in 2023 and the highest annual total since 2015. One US government report of 248 counterfeit fan assemblies in May 2024 inflates that figure, and it's fair to strip it out. Reporting still rose about 3 percent without it, on top of an increase the year before.

The composition matters more than the total. Obsolete components were 42.75 percent of 2024 reports, which surprises nobody. Active parts readily available through authorized channels made up more than a quarter of cases, and were reported more than twice as often as active parts with long manufacturer lead times. Counterfeiters are working the parts your risk register calls safe. Add to that the 29.4 percent of reported parts carrying manufacturer brands never previously recorded by ERAI, and 21 percent of flagged brands being new to the watchlist, and the target base is spreading rather than concentrating.

The 2023 report, published on 22 March 2024, shows the same shape a year earlier: obsolete at 45.7 percent, active long-lead at 32.8, active readily available at 13.2. It also closes an old file. Capacitors were 0.5 percent of 2023 reports against 6.72 percent across the five years before that, so the passive-shortage wave has passed.

Look at who finds this material. In 2024, third-party test labs filed 37.35 percent of reports and independent distributors 31.85 percent, while component manufacturers filed 5.78 percent. Detection lives in the independent chain. The people most likely to catch a bad reel are the ones handling brokered stock for a living, which is an argument for buying through a distributor that tests rather than around one.

What happens to the part in transit?

Between the broker's dock and yours the part is palletized, consolidated with unrelated freight, cross-docked, and cleared through customs, and several of those steps can involve opening and resealing the packaging. Customs officers open boxes to confirm contents and declared values. Consolidators break and rebuild pallets. None of it is visible to you unless your contract says it has to be.

Third-party logistics providers add another node. Pierce Distribution opened a 225,000 square foot parts distribution center in Dupont, Washington in June 2024, the kind of regional hub where inbound material is received, stored, kitted and shipped on again. Route your parts through one and that's a whole handling layer between the broker and your plant.

The exposures here are dull and real: humidity against moisture-sensitive devices whose dry bags were opened for inspection, temperature in an unconditioned trailer, mechanical shock, misrouting. Logistics vendors market precision handling and just-in-time reliability without publishing on-time rates, damage rates or cycle times. Judge the lane on your own SLAs and history instead.

What should receiving do with a broker lot?

Receiving is the last gate before the part disappears into your inventory, so hold a brokered lot there against its paperwork and its photographs before booking it into stock. Check the certificate of conformance, the packing list and any traceability document from the original holder. Read the manufacturer lot codes and date codes against each other and against what you were quoted. Inconsistent date codes inside one reel is the oldest signal there is.

For anything high-risk, ask for macro photography of markings, date codes and pin condition before the lot ships, and review the images then rather than after. X-ray against a known-good exemplar answers most of the rest in an hour, and IDEA-STD-1010 gives your inspectors defensible visual criteria instead of a judgement call.

When something fails, quarantine it and keep it. Do not return it to the seller, and report it to ERAI, stripping supplier and customer identifiers if you need to. That report is what raises the inspection level on the same part number for the next buyer, and eventually for you, because the database you query in eighteen months is built from reports like yours.

What happens after your dock, on the way to the line?

Inside the plant the part is governed by its PFEP record, which decides where it is stored, how often it is replenished and how much of it sits at the workstation. Lineside storage for each part is sized as the maximum replenishment interval multiplied by usage per unit time, plus safety stock, and delivery frequency follows the part's class: every 30 minutes for high-runners, every two hours for the middle band, daily for the slow movers. Flow racks enforce FIFO so lots don't get mixed by an operator reaching for the nearest bin.

Two things there are worth a buyer's attention. Carry the sourcing channel as a field in PFEP, so brokered material stays traceable after it leaves the warehouse and can be released to the line in small batches. If a lot is later found suspect, the number of units already consumed is the difference between a rework and a recall. Then audit those records quarterly. A broker part approved as a stopgap during an allocation window has a habit of staying live long after the franchised pipe recovered, which is how a plant ends up depending on open-market supply nobody decided to depend on.

Plant logistics has moved in your favour here. Škoda Auto, describing its post-pandemic rebuild in 2023, raised warehouse capacity by 60 percent and went from 11 production scenarios to 45, on the stated grounds that the ideal of leanness had been replaced by the ideal of resilience. Bigger central buffers mean a brokered lot usually sits before it feeds, and that's time you can use.

How long does this run?

Plan on elevated open-market risk lasting through the late 2020s. ERAI reports rose in each year from 2022 to 2024 with no sign of a reversal, obsolete platforms keep needing parts nobody makes any more, and the supply conditions that push buyers onto the open market are still in place. As of May 2026, TSMC's Fab 21 in Phoenix was quoting 39 to 52 weeks for cutting-edge customers. Intel's Fab 52 in Arizona reached high-volume manufacturing on 18A in Q1 2026, while the Ohio mega fab slipped to a 2030 target. New capacity arrives slowly and unevenly, and the 52-week microcontroller queue we wrote about in August hasn't shortened since.

What to put on the purchase order

1. Name the standard and the methods. "AS6081 supplier" is not a specification. Write AS6171 into the quality clauses, list the tests you want (visual to IDEA-STD-1010, X-ray, XRF, decap, electrical) and state the sampling plan. Unspecified means unperformed.

2. Ask who is holding the stock. One question, answered in one line: does the seller physically have it, or is this a drop-ship from a third party? The answer tells you where the inspection has to happen and who you'll be chasing if the lot is wrong.

3. Require the lot's history before it ships. Source type, storage conditions, prior ownership where known, and photographs of the actual reel rather than a catalogue image. Rejecting a lot on a photograph costs a day. Rejecting it after it's kitted costs a build.

4. Write the quarantine clause. Suspect material stays at your site, does not go back to the seller, and gets reported. Agree that before you need it, not during the argument.

5. Keep the channel in your master data. Flag brokered lots in MRP and PFEP, review the flags every quarter, and close them out when authorized supply returns. Traceability you can query beats traceability in an email thread.

That is the work, and most of it happens before the part moves. We've sourced obsolete and allocated parts to order since 2004, and every suspect lot we ship can go through the Malmö lab first. If a part on your BOM has gone quiet, send us the line or check it against our live stock.

Frequently asked questions

Does an AS6081 certificate mean my lot was tested?

No. The certificate is company-level: it confirms the distributor's processes. Test methods live in AS6171, and they only run on your reel if your purchase order names them.

How many counterfeit parts were reported in 2024?

ERAI logged 1,055 suspect parts, up 25 percent on 2023 and the highest since 2015. A single report of 248 fan assemblies drove much of the rise; reporting still grew about 3 percent without it.

What should I put on a purchase order to a broker?

Named AS6171 methods and a sampling plan, who physically holds the stock, photographs of markings and date codes before shipment, lot traceability, and a quarantine clause for suspect material.

Is a pure broker safe to buy from?

It's workable on low-risk commodity lines if you own the inspection. A pure broker never handles the parts, so there's no test data and usually no RMA. For obsolete or high-value silicon, buy from a stocking distributor with a lab.
