Engineering Selection Recommendations

24LC02BHT-E/MS (Microchip Technology) – Primary selection for applications requiring the full extended temperature range (-40°C to 125°C). Maintains ROHS3 compliance and active production status. Suitable for industrial and high-temperature environments.

BR24A02FVM-WMTR (Rohm Semiconductor) – Recommended substitute for automotive and industrial applications. Carries AEC-Q100 qualification, indicating suitability for automotive-grade reliability standards. Operating temperature range extends to 105°C, adequate for most industrial applications. ROHS3 compliant with active production status.

BR24G02FVM-3GTTR (Rohm Semiconductor) – Recommended substitute for applications with reduced temperature requirements (-40°C to 85°C) and potential low-voltage operation needs. Extended supply voltage range (1.6V minimum) provides flexibility for battery-powered or low-power applications. ROHS3 compliant with active production status.

All three parts maintain identical memory capacity, I2C interface specifications, and 8-MSOP packaging compatibility. Selection should be based on specific application temperature requirements and voltage supply constraints.

Frequently Asked Questions (FAQ)

Q: Can BR24A02FVM-WMTR replace 24LC02BHT-E/MS in all applications?

A: BR24A02FVM-WMTR is functionally compatible for applications operating within -40°C to 105°C temperature range. Applications requiring operation above 105°C must use the original 24LC02BHT-E/MS, which supports temperatures to 125°C.

Q: What is the difference between the two Rohm substitute parts?

A: BR24A02FVM-WMTR operates to 105°C with 2.5V minimum supply voltage and includes AEC-Q100 automotive qualification. BR24G02FVM-3GTTR operates to 85°C with 1.6V minimum supply voltage, offering extended low-voltage capability without automotive qualification.

Q: Are there package dimension differences between the main part and substitutes?

A: All parts use 8-MSOP packaging. The main part specifies 0.118" width (3.00mm), while both Rohm substitutes specify 0.110" width (2.80mm). These minor dimensional variations are within standard MSOP tolerance specifications and do not affect PCB footprint compatibility.

Q: Do all parts maintain I2C 400 kHz compatibility?

A: Yes. The main part and both substitute parts operate at 400 kHz I2C clock frequency with identical 5ms write cycle time and 900 ns access time specifications, ensuring direct functional replacement.

Q: Are all parts RoHS compliant?

A: Yes. The 24LC02BHT-E/MS and both substitute parts (BR24A02FVM-WMTR and BR24G02FVM-3GTTR) are ROHS3 compliant.
