The verdict is based on public parameters only (capacity/interface/package/pins/speed); timing margins, temperature grades, certifications and lot differences are not covered. Confirm with both datasheets before replacing; ask us for samples or validation support.

Pre-replacement Checklist (NAND FLASH)
  1. Page/block size & organization (2K+64B, 4K+256B, etc.)
  2. ECC scheme (on-die vs controller, sufficient strength)
  3. Bad-block management & max factory bad blocks
  4. ONFI/timing modes compatibility with the controller
  5. Cell type (SLC/MLC/TLC), endurance & retention
  6. Package & pad definition

These are standard checkpoints for this product type. Verify each item and pilot-test before full switch-in. Ask us for samples, a replacement assessment report or FAE support - free samples and validation assistance provided.
