Buying FAQ — W25Q128JVSIQ

Is W25Q128JVSIQ drop-in for W25Q64?

Often pin-compatible in SOIC-8, but capacity and SFDP / status bits differ. Update flash layout and verify erase block assumptions.

Lead time for large reels of W25Q128JVSIQ?

Depends on factory vs open-market mix. Give monthly forecast; we can stage partial deliveries to protect line-down.

Can you cross to Macronix / ISSI equivalents?

Yes after electrical and firmware review. Send the approved AVL so we only quote listed alternates.

What QC steps do you run on SPI flash lots?

Marking check, sample JEDEC ID read and packaging integrity. Deeper programming tests available on request for critical builds.
