Electronics Procurement From China
1 resources tagged with "Procurement"
Procurement for China-sourced electronics lives or dies on the BOM. A clean bill of materials lists the manufacturer part number (MPN) for every critical line, the lifecycle status, and an approved vendor list (AVL) — so a factory can't quietly swap a Texas Instruments regulator for an unmarked equivalent. The most common procurement failure is a BOM that specifies a generic '10µF cap' instead of an MPN, which hands the factory free rein to buy the cheapest reel on Huaqiangbei.
Good procurement means the PO references a frozen, version-controlled BOM with MPNs and an AVL, not just a product description. We verify Chinese distributor authenticity for critical ICs and flag any line marked NRND (not recommended for new designs) or end-of-life before it bites a second production run.

FAQ
Why do I need MPNs instead of generic part descriptions in my BOM?
A generic description like '0.1µF 0402 cap' lets the factory source any part that fits, including counterfeit or out-of-spec reels. An MPN plus an approved vendor list locks the exact part and supplier.
How do I check whether a Chinese distributor is selling authentic components?
Cross-check the distributor against the chip maker's authorized partner list, request lot/date codes and CoCs, and X-ray or decap suspect parts for high-value ICs. Prices far below market are the strongest counterfeit signal.
What is an AVL and why does procurement need it?
An approved vendor list names which manufacturers and distributors are allowed for each part. It prevents unauthorized substitutions and gives you a defined fallback when a part goes NRND or end-of-life.
