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 (EEPROM)
- Bus & device address (I2C address pin wiring)
- Capacity & page-write size (16/32/64B, affects write speed)
- Write-cycle time & endurance (1M cycles)
- Voltage range & standby current (critical for battery designs)
- Package (SOP8/SOT23-5/TSSOP8) & pinout
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.
