Product details

Industrial temperature grade and supply compatibility

The M24C04-WMN6P: At 5.5V maximum it tolerates a 5V rail with typical ±10% tolerance.

NRND — design-in implications

STMicroelectronics lists the M24C04-WMN6P as NRND (Not Recommended for New Designs). The part remains available for existing production runs, but new board spins should target an active alternative from the same M24C04 family or a pin-compatible second source. For a BOM that already qualifies this EEPROM, the NRND status means the procurement team should secure a last-time-buy window or confirm an alternate source before the manufacturer issues an EOL notice. The 8-SOIC footprint is shared across many 4Kbit I²C EEPROMs, so a pin-compatible swap is feasible without a board respin.

Frequently asked questions

What is the closest pin-compatible alternative to M24C04-WMN6P in this EEPROM family?

The M24C04 family includes multiple 8-SOIC variants with the same pinout — the key difference is the temperature grade and supply range. An active alternative with the same 2.5V-5.5V supply and -40°C to +85°C range would be a direct drop-in replacement without a PCB layout change. Confirm the exact order code with your distributor to match the temperature and voltage spec.
