Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

For applications requiring identical 8-MSOP packaging with 400 kHz operation, BR24L01AFVM-WTR and BR24T01FVM-WTR are active products from Rohm Semiconductor with verified inventory and full RoHS3 compliance. Both maintain the same clock frequency and package format as the original 24VL014HT/MS.

For applications where higher clock frequency (1 MHz) is acceptable, AT24C01D-XHM-T and AT24C01D-XHM-B from Microchip Technology provide enhanced performance with extended operating temperature range (-40°C to 85°C) and are active products suitable for new designs.

Alternative Package Formats:

When 8-TSSOP packaging is acceptable, BR24G01FVT-3GE2, BR24L01AFVT-WE2, and BR24T01FVT-WE2 provide equivalent electrical functionality with active product status and full compliance certifications.

Legacy Alternatives (Not Recommended for New Designs):

BR24G01FVJ-3GTE2 and BR24L01AFV-WE2 are marked as "Not For New Designs" and should be used only when existing inventory constraints or legacy system requirements necessitate their selection.

Frequently Asked Questions (FAQ)

Q: Can AT24C01D-XHM-T replace 24VL014HT/MS directly?

A: Electrical substitution is valid. Both are 1Kbit I2C EEPROM devices with 128 x 8 organization and 5ms write cycle time. The AT24C01D-XHM-T operates at 1 MHz (higher than the 400 kHz original) and features extended temperature range (-40°C to 85°C versus -20°C to 85°C). Package format differs: AT24C01D-XHM-T uses 8-TSSOP while 24VL014HT/MS uses 8-MSOP. PCB layout modification is required.

Q: What is the difference between BR24L01AFVM-WTR and BR24T01FVM-WTR?

A: Both are 1Kbit I2C EEPROM devices in 8-MSOP packaging with 400 kHz clock frequency and identical electrical specifications. The primary difference is supply voltage range: BR24L01AFVM-WTR operates 1.8V ~ 5.5V while BR24T01FVM-WTR operates 1.6V ~ 5.5V. Selection depends on minimum supply voltage requirements of the target application.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry RoHS3 compliance certification, matching the original 24VL014HT/MS specification.

Q: Which substitute offers the best performance upgrade?

A: AT24C01D-XHM-T and AT24C01D-XHM-B provide the highest clock frequency at 1 MHz (versus 400 kHz original) with faster access time of 4.5 µs. These parts are active products from Microchip Technology suitable for new designs.

Q: Can I use BR24G01FVJ-3GTE2 in a new design?

A: BR24G01FVJ-3GTE2 is marked "Not For New Designs" by the manufacturer. While electrically compatible, active alternatives such as BR24G01FVM-3AGTTR, BR24G01FVT-3GE2, or BR24L01AFVM-WTR should be prioritized for new applications.

Q: What packaging options are available for 1Kbit I2C EEPROM substitutes?

A: Substitute parts are available in three package formats: 8-MSOP (0.110" to 0.118" width), 8-TSSOP (0.173" width), and 8-LSSOP (0.173" width). Package selection affects PCB footprint and thermal characteristics but does not alter electrical functionality.
