Engineering Selection Recommendations

Direct Equivalent (Preferred for Replacement): 24LC16BHT-E/ST is the direct equivalent from Microchip Technology, differing only in packaging format (Tape & Reel versus Tube). Both parts maintain identical electrical specifications and operating ranges. This part is recommended for direct substitution when supply of the original part is unavailable.

Active Product Alternatives: BR24G16FVM-3GTTR, BR24G16FVT-3GE2, BR24T16FVT-WE2, CAT24C16YI-GT3, CAV24C16YE-GT3, and R1EX24016ATAS0I#S0 are all in active product status. CAV24C16YE-GT3 from onsemi matches the full voltage and temperature specifications of the 24LC16BH-E/ST (2.5V ~ 5.5V, -40°C ~ 125°C) and includes AEC-Q100 automotive qualification. This part is suitable for applications requiring extended temperature range operation.

Discontinued Product Alternatives: BR24G16FV-3GTE2, BR24G16FVJ-3GTE2, and BR24L16FV-WE2 are marked as "Not For New Designs" and should be avoided for new product development. These parts are listed for reference only in legacy system maintenance scenarios.

Package Considerations: All substitute parts maintain 8-pin surface mount configurations with compatible footprints. BR24G16FVM-3GTTR uses 8-MSOP package (0.110" width) versus the standard 8-TSSOP (0.173" width), requiring PCB layout verification before substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute 24LC16BH-E/ST with 24LC16BHT-E/ST? A: Yes. Both parts are manufactured by Microchip Technology with identical electrical and functional specifications. The only difference is packaging format: 24LC16BH-E/ST is supplied in Tube packaging while 24LC16BHT-E/ST is supplied in Tape & Reel format. They are functionally interchangeable.

Q: What is the difference between Microchip and Rohm EEPROM parts? A: All 16Kbit I2C EEPROM parts listed share the same core electrical specifications (16Kbit capacity, 2K x 8 organization, 400 kHz I2C, 5ms write cycle). Rohm parts (BR24G16 series) operate at lower minimum voltage (1.6V) and reduced maximum temperature (-40°C ~ 85°C) compared to the Microchip 24LC16BH-E/ST (2.5V ~ 5.5V, -40°C ~ 125°C). Rohm parts are suitable for applications not requiring the extended temperature range.

Q: Is CAV24C16YE-GT3 suitable for automotive applications? A: Yes. CAV24C16YE-GT3 from onsemi is qualified to AEC-Q100 automotive standard and maintains the full voltage range (2.5V ~ 5.5V) and extended temperature range (-40°C ~ 125°C) of the 24LC16BH-E/ST, making it suitable for automotive system replacement.

Q: Can I use BR24G16FVM-3GTTR as a substitute? A: BR24G16FVM-3GTTR is functionally compatible but uses 8-MSOP package (0.110" width) instead of 8-TSSOP (0.173" width). PCB footprint verification is required before substitution. This part is in active product status and suitable for new designs.

Q: What does "Not For New Designs" mean? A: Parts marked "Not For New Designs" are in mature or discontinued product lifecycle phases. While they remain functionally compatible, manufacturers recommend using active status alternatives for new product development. These parts are listed for legacy system maintenance reference only.

Q: Are all listed parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and carry identical REACH unaffected status as the 24LC16BH-E/ST.

Q: What is the significance of access time (900 ns)? A: Access time specifies the maximum delay from I2C address/command transmission to data availability. The 24LC16BH-E/ST and compatible substitutes (24LC16BHT-E/ST, CAT24C16YI-GT3, CAV24C16YE-GT3, R1EX24016ATAS0I#S0) all specify 900 ns access time. Rohm parts do not specify access time but maintain the same 400 kHz I2C clock frequency and 5ms write cycle, ensuring functional compatibility.
