Electronic Component Sourcing from China
1 resources tagged with "Component Sourcing"
Component sourcing for China-built electronics lives and dies on the BOM: every line needs a manufacturer part number (MPN), not a generic 'capacitor 10uF' description, plus a lifecycle status and an approved vendor list (AVL) so the factory can't quietly substitute. The biggest risk on Chinese distributor channels like LCSC, 1688, and Huaqiangbei is counterfeit or relabeled parts — we verify distributor authorization and date codes before parts go into production. A clean BOM with locked MPNs is the single best defense against silent substitution.
When you source components, an MPN-locked BOM with an AVL tells the factory exactly which part from which manufacturer is acceptable, closing the door on cheaper unauthorized substitutes. The common pitfall is leaving generic specs on the BOM, which lets a factory buy the cheapest equivalent — sometimes a counterfeit — without technically breaking the order.

FAQ
What columns does a sourcing BOM need?
At minimum: line number, manufacturer, MPN, description/value, package/footprint, quantity per unit, reference designators, lifecycle status, and an approved alternate (AVL). Locking the MPN is what prevents unauthorized substitution.
How do I avoid counterfeit components from Chinese distributors?
Buy from authorized distributors, check date codes and lot consistency, and decap or X-ray suspect parts for high-risk lines. Huaqiangbei and 1688 carry genuine stock, but they also carry relabeled and counterfeit parts, so verification matters.
