- Critical evidence
- Label, package photo, prior record

Start with the exact historical requirement
Use the full part number from the board, label, datasheet, or previous purchase order and identify the equipment or production context.
- Full suffix and package
- Previous brand and date code
- Required quantity and delivery window
- Known lifecycle or EOL notice
Define acceptable sourcing conditions
State the commercial and quality boundaries before channel review begins.

Buyer questions
Can WMSIC guarantee that every obsolete part is available?
Availability depends on the exact suffix, condition, quantity, channel, and evidence requirements. Each request receives a separate sourcing review.
What should I send when the label is damaged?
Send clear board photos, surrounding circuit references, the equipment model, a datasheet candidate, and any previous order record.
Can I request alternatives for an obsolete component?
Yes. State whether pin compatibility, electrical equivalence, package fit, firmware impact, or redesign is acceptable.
