AT24C512C-SSHD-T is a 512 kbit I2C EEPROM in 8-lead SOIC. Reviewed candidates are downgrade risks, not verified drop-in replacements.

AI replacement insight

Electrical riskhigh

kept parts are 3.6 V max

Package riskmedium

SOIC matches but pinout is unverified

Firmware riskhigh

2/4 kbit cannot replace 512 kbit maps

Sourcing riskmedium

lifecycle data is limited

Can it be replaced directly?

No verified pin-compatible replacement is present in this candidate set.

Best replacement path

Prefer another 512 kbit I2C EEPROM with 8-lead SOIC, 1.7-5.5 V, 1 MHz, and verified pinout.

Main risk

Lower-density parts can break firmware storage maps and 5 V designs.
