Is there a pin-compatible replacement for M24M02-DRMN6TP?

Yes, parts like M24M01-RMN6TP from the same STMicroelectronics family share the same SO8 package and I2C pinout. However, they are not functionally identical due to different memory sizes, so they are not drop-in replacements without verification.

What risks should I check before replacing M24M02-DRMN6TP?

Key risks to verify are: 1) Memory Size: Ensure the replacement has enough capacity for your application. 2) Supply Voltage: Confirm the replacement supports your system's full voltage range, especially down to 1.8V. 3) Firmware: Software changes may be needed to accommodate a different memory size.

M24M02-DRMN6TP Alternatives, Datasheet & Cross Reference | STMicroelectronics

M24M02-DRMN6TP is a 2Mbit I2C EEPROM from STMicroelectronics in an SO8 package. Alternatives exist within the same family, but often require careful review of memory size and supply voltage.

AI replacement insight

Firmware riskhigh

Memory address space is different, requiring code changes.

Electrical riskmedium

Some alternatives have a higher minimum supply voltage.

Package risklow

Candidates share the common SO8 package.

Can it be replaced directly?

No direct drop-in replacement with identical key parameters was found. The closest options are downgrades in memory capacity.

Best replacement path

M24M01-RMN6TP is the closest alternative, matching voltage, interface, and package, but with half the memory (1Mbit). Verify memory requirements before use.

Main risk

The primary risk is insufficient memory capacity. The target has 2Mbit, while the best alternatives have 1Mbit or less, requiring firmware validation.

Recommended alternatives

A close alternative with identical voltage, interface, and package, but with 1Mbit memory instead of 2Mbit.
