Best Alternatives to M24C64-WMN6TP

Package: 8-SOIC (0.154", 3.90mm Width)StmicroelectronicsMemoryPackage: Tape & Reel (TR) Cut Tape (CT) Digi-Reel®Memory Type: Non-VolatileTechnology: EEPROMMemory Size: 64KbitClock Frequency: 1 MHz

The M24C64-WMN6TP is a 64-Kbit I2C EEPROM from STMicroelectronics in an SO8N package. When searching for alternatives, focus on matching the 64-Kbit memory size, I2C interface, and 2.5V-5.5V supply range.

AI replacement insight

Electrical risklow

Low if staying within the M24C64 family, as voltage ranges are compatible.

Package risklow

Low as SO8N is a standard package with consistent dimensions in the family.

Firmware riskhigh

High if changing memory density, which requires software modification.

Can it be replaced directly?

Direct replacement for M24C64-WMN6TP should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct replacement path is to the M24C64-RMN6TP, a variant with a wider voltage range. For an upgrade, consider the M24256 series.

Main risk

The main risk is selecting a part with a different memory size (e.g., 8Kbit or 256Kbit), which would require software changes.
