Engineering Selection Recommendations

Microchip Technology 24LC024-E/SN and 24LC02B-E/SN: Both parts maintain identical memory specifications and package form factor to the main part. The 24LC02B-E/SN carries DiGi-Electronics Programmable verification status. Clock frequency reduction from 1 MHz to 400 kHz and access time increase from 400 ns to 900 ns do not affect functional compatibility in standard I2C applications. Both parts support the full -40°C to 125°C operating range.

Rohm Semiconductor BR24 Series: The BR24A02F-WME2 and BR24A02FJ-WME2 variants include AEC-Q100 automotive qualification. The BR24L02F-WE2 and BR24L02FJ-WE2 variants feature extended low-voltage operation (1.8V minimum) with DiGi-Electronics Programmable verification. Operating temperature range is reduced to -40°C to 85°C. Package variants include 8-SOP and 8-SOP-J options. The BR24G02F-3GTE2 supports minimum 1.6V operation with -40°C to 85°C range.

onsemi CAV24C02WE-GT3: Maintains full -40°C to 125°C operating range with AEC-Q100 automotive qualification. Clock frequency and access time specifications match the 24LC024-E/SN variant. 8-SOIC package provides direct footprint compatibility.

STMicroelectronics M24C02-DRMN3TP/K: Operates at 1 MHz clock frequency matching the main part. Supports extended low-voltage operation (1.8V minimum) with AEC-Q100 automotive qualification. Access time of 450 ns is intermediate between the main part and standard 400 kHz variants. Maintains full -40°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 kHz I2C EEPROM as a direct replacement for the 1 MHz 24LC024H-E/SN?

A: Yes. The 400 kHz variants operate at reduced clock frequency but maintain full functional compatibility. I2C bus speed is determined by the slowest device on the bus. Applications designed for 1 MHz operation will function correctly with 400 kHz devices, though data transfer rates will be limited to 400 kHz maximum.

Q: What is the difference between 8-SOIC and 8-SOP packages?

A: Both are 8-pin surface mount packages with identical pin counts and I2C signal assignments. The 8-SOIC package has a width of 0.154" (3.90mm), while 8-SOP packages typically measure 0.173" (4.40mm) in width. Standard PCB footprints accommodate both package types. Verify footprint compatibility with your specific PCB design.

Q: Are the Rohm BR24L02F variants suitable for low-voltage applications?

A: The BR24L02F-WE2 and BR24L02FJ-WE2 support minimum supply voltage of 1.8V, compared to 2.5V for the main part. These variants are suitable for low-voltage system designs. Operating temperature range is -40°C to 85°C, which is narrower than the main part's -40°C to 125°C range.

Q: Which substitute parts carry automotive qualification?

A: The BR24A02F-WME2, BR24A02FJ-WME2, CAV24C02WE-GT3, and M24C02-DRMN3TP/K all carry AEC-Q100 automotive qualification. These parts are suitable for automotive-grade applications requiring formal qualification documentation.

Q: What is the impact of access time differences between 400 ns and 900 ns?

A: Access time defines the delay from address setup to data output availability. The 400 ns specification of the main part and M24C02-DRMN3TP/K provides faster read response compared to 900 ns variants. For standard I2C memory applications, both specifications meet typical system timing requirements. Critical timing-sensitive applications should verify compatibility with specific system requirements.

Q: Can I substitute the 24LC024H-E/SN with parts having different operating temperature ranges?

A: Substitution is valid only if the application operating temperature range falls within the substitute part's specification. The main part supports -40°C to 125°C. Rohm BR24 variants support -40°C to 85°C maximum. Verify your application's actual operating temperature requirements before selecting a substitute with a narrower temperature range.
