Engineering Selection Recommendations

Direct Replacement (Identical Specifications)

24LC024H-I/MS serves as a direct substitute with matching 1 MHz clock frequency, 400 ns access time, and identical voltage supply range. Packaging differs only in tape format (Tube versus Tape & Reel), with no functional impact on circuit operation.

Microchip Technology 400 kHz Alternatives

24AA024T-I/MS, 24AA02T-I/MS, 24LC024T-I/MS, 24LC02BT-I/MS, and 24LCS52T-I/MS operate at reduced clock frequency (400 kHz) with extended access time (900 ns). These parts maintain 2Kbit capacity and I2C interface compatibility. 24AA024T-I/MS and 24AA02T-I/MS support lower minimum supply voltage (1.7V). 24LCS52T-I/MS supports lower minimum supply voltage (2.2V). All maintain Active product status and ROHS3 compliance.

Rohm Semiconductor Alternatives

BR24A02FVM-WMTR operates at 400 kHz with extended operating temperature range (-40°C to 105°C) and automotive qualification (AEC-Q100). BR24G02FVJ-3AGTE2 matches 1 MHz clock frequency with lower minimum supply voltage (1.6V) and 8-TSSOP package variant. BR24G02FVM-3GTTR operates at 400 kHz with 8-MSOP package and lower minimum supply voltage (1.6V). BR24G02FVJ-3GTE2 carries "Not For New Designs" status and is not recommended for new circuit implementations.

Product Status Consideration

All Microchip Technology substitutes maintain Active status. BR24G02FVJ-3GTE2 is designated "Not For New Designs" and should be avoided in new applications. All other Rohm Semiconductor parts maintain Active status.

Frequently Asked Questions (FAQ)

Q: Can 24LC024H-I/MS be replaced with 24AA024T-I/MS?

A: Yes. Both devices maintain 2Kbit capacity, 256 x 8 organization, and I2C interface. The 24AA024T-I/MS operates at 400 kHz versus 1 MHz, resulting in 900 ns access time versus 400 ns. This represents reduced performance but maintains functional compatibility. The 24AA024T-I/MS supports lower minimum supply voltage (1.7V) compared to 2.5V minimum for the main part.

Q: What is the difference between 8-MSOP and 8-TSSOP packages?

A: Both packages contain 8 pins in surface mount configuration with equivalent pinout for I2C EEPROM devices. 8-MSOP measures 0.118" width (3.00mm), while 8-TSSOP measures 0.118" width (3.00mm) for standard variants. Package selection depends on PCB layout requirements and assembly equipment compatibility. Electrical functionality remains identical.

Q: Are Rohm Semiconductor parts compatible with Microchip Technology designs?

A: Yes. BR24A02FVM-WMTR, BR24G02FVJ-3AGTE2, and BR24G02FVM-3GTTR maintain identical 2Kbit capacity, 256 x 8 organization, and I2C interface protocol. All operate within compatible voltage and temperature ranges. Rohm parts support lower minimum supply voltage (1.6V to 2.5V) compared to Microchip 2.5V minimum, providing broader operating range compatibility.

Q: Why does BR24G02FVJ-3GTE2 show "Not For New Designs" status?

A: Parts designated "Not For New Designs" indicate manufacturer discontinuation or transition planning. While functionally compatible, these parts should not be selected for new circuit implementations. Active alternatives such as BR24G02FVJ-3AGTE2 or BR24G02FVM-3GTTR are recommended instead.

Q: What is the impact of 400 kHz versus 1 MHz clock frequency?

A: Clock frequency determines maximum I2C bus speed. 1 MHz operation enables faster data transfer rates compared to 400 kHz. Devices rated for 400 kHz operate at reduced speed but remain compatible with 1 MHz-capable systems through backward compatibility. System timing requirements determine whether reduced frequency impacts application performance.

Q: Can 24LC024HT-I/MS operate at supply voltages below 2.5V?

A: No. The 24LC024HT-I/MS minimum supply voltage is 2.5V. For applications requiring operation below 2.5V, alternatives such as 24AA024T-I/MS (1.7V minimum), BR24G02FVJ-3AGTE2 (1.6V minimum), or BR24G02FVM-3GTTR (1.6V minimum) provide extended low-voltage capability.
