STMicroelectronics
Needs validationlow risk
A potential upgrade with 16Kbit memory from the same series, in the same package and voltage range.
Best Alternatives to M24C02-RMN6TP
Finding a substitute for the M24C02-RMN6TP involves choosing between parts with identical memory but different voltage, or parts with identical voltage but larger memory. Several options exist within the STMicroelectronics M24 series, each with specific trade-offs.
AI replacement insight
Electrical riskmedium
Some alternatives have a higher minimum supply voltage (2.5V vs 1.8V).
Package risklow
All reviewed candidates share the same SO8N package.
Firmware riskhigh
Upgrading memory size requires changes to I2C addressing logic.
Can it be replaced directly?
No direct drop-in replacement is confirmed. The M24C02-WMN6TP has the same memory size but a narrower voltage range. The M24C16-RMN6TP has a compatible voltage range but larger memory, requiring firmware review.
Best replacement path
Upgrade to a larger memory device from the same ST M24Cxx series, such as the M24C16-RMN6TP, after verifying I2C addressing.
Main risk
The primary risks are electrical incompatibility due to minimum supply voltage differences and functional issues from memory size changes affecting I2C addressing.
