FlowMarket
Where to find electronic components: FlowMarket is a B2B sourcing network powered by an AI agent. You describe the requirement — part numbers or a whole BOM, quantities, the delivery window and the traceability your build needs — and the agent matches you with distributors and suppliers who cover those parts, then requests prices, stock and lead times so you can compare them in one place.
Sourcing electronic components
Component buying has two modes and they barely resemble each other. When a part is in stock everywhere, it is a price comparison and takes ten minutes. When it is on allocation, obsolete or single-sourced, it becomes a search for anyone holding real inventory, and the price stops being the interesting number. Most BOMs contain both kinds of line at once, which is why quoting a BOM as a single job usually goes badly.
The useful move is to say which lines are the hard ones. A supplier who knows that three of forty parts are the constraint will answer about those three; one who receives an undifferentiated list will quote the easy thirty-seven and go quiet on the rest.
Where you buy decides what you get
- Authorised distribution — franchised by the manufacturer, with unbroken traceability and warranty. The default for anything going into production, and the only route that reliably survives an audit.
- Independent and open market — brokers holding stock the franchised channel cannot supply. Genuinely useful in a shortage, and where counterfeit risk lives. Ask what testing and documentation come with the parts.
- Excess and surplus — legitimate overstock from other manufacturers, often the cheapest route for a mature part. Traceability varies enormously; ask before, not after.
- Direct from the manufacturer — worth it at volume or for a custom part, and usually gated by minimum quantities that only make sense above a certain run rate.
Counterfeits are a supply-chain question, not a testing one
Counterfeit and remarked parts reach the market through the open channel, and they are not reliably caught by looking at them. The defences that work are procedural: buy franchised where you can, demand a certificate of conformity and traceability to the manufacturer, and where you must buy independently, use a supplier who tests to a recognised standard and will show you the report.
The cost of getting this wrong is not the parts. It is a production run built with them, discovered in the field. On any programme where that matters, say so in the enquiry — it changes which suppliers should be answering at all.
Lifecycle, allocation and the last-time buy
Semiconductor lifecycles are shorter than the products built with them, so obsolescence is scheduled rather than accidental. When a manufacturer issues an end-of-life notice, there is a window for a last-time buy and then nothing. Knowing where each critical line sits in its lifecycle is the difference between a planned bridge purchase and an emergency at a broker's price.
Allocation works differently: the part still exists, but demand outruns supply and lead times stretch from weeks to a year. When it happens, the answer is rarely a better price and usually a qualified alternate. Ask suppliers for form-fit-function equivalents alongside the original — a good one volunteers them.
What to put in the enquiry
- Manufacturer part numbers — not descriptions. "100 nF 0402" matches thousands of parts across a dozen tolerance, voltage and dielectric combinations.
- Quantity and call-off pattern — annual usage and how it is drawn down. Pricing breaks and stock commitments both follow the pattern, not the single order.
- Packaging — reel, cut tape, tray or tube. It sounds trivial until an assembler charges to re-reel a hand-counted bag.
- Documentation — RoHS and REACH declarations, certificate of conformity, date-code limits and traceability depth. Requested up front they cost nothing; requested afterwards the batch may not qualify.
- Whether alternates are acceptable — and who approves them. This single line determines how much a supplier can actually help you.
How the AI agent matches suppliers
The agent reads your requirement rather than your keywords. It searches the FlowMarket network and connected industrial directories together, scores every candidate on how well it answers what you described — component category, channel, quantity, documentation, geography — and drops anything that does not clear the bar. Each match comes back with a plain-language reason, which is faster than working through catalogue sites that all claim to have everything.
