Why this sourcing work is risky
A converter alternate can match the broad function but still fail on interface, timing, power or analog performance.
Supplier offer warning
If a supplier refuses label photos, packing photos or basic traceability notes for high-value ICs, treat the offer as high risk until another channel is reviewed.

Photos and documents to request
| Evidence | Why it helps | When to request it |
|---|---|---|
| Label photo | Confirms part number, lot and packing clue | High-value or urgent purchases |
| Packaging photo | Shows reel, tray, tube or moisture barrier condition | Package-sensitive parts |
| Supplier invoice trail | Supports channel review | Obsolete or shortage demand |
| Datasheet match | Confirms suffix and temperature grade | Any alternate discussion |
