Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

For applications requiring identical 400 kHz operation with 8-MSOP packaging, BR24G02FVM-3GTTR (Rohm Semiconductor) provides direct functional equivalence with extended voltage range (1.6V ~ 5.5V) and active product status. This part maintains the same memory organization, interface protocol, and write cycle time.

For applications where higher clock frequency (1 MHz) operation is acceptable, AT24C02D-XHM-B or AT24C02D-XHM-T (Microchip Technology) offer enhanced performance with faster access time (4.5 µs) and extended operating temperature range (-40°C ~ 85°C). These parts are available in 8-TSSOP packaging and maintain active production status.

BR24G02FVJ-3AGTE2 (Rohm Semiconductor) provides 1 MHz operation in 8-TSSOP packaging with extended voltage range and active status, suitable for designs where package form factor flexibility is required.

Secondary Substitutes (Not For New Designs):

BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, and BR24L02FVJ-WE2 are classified as "Not For New Designs" and should be used only for legacy system maintenance or when existing inventory constraints require their use.

Compliance Considerations:

All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, consistent with the original 24VL024HT/MS specification. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can AT24C02D-XHM-B replace 24VL024HT/MS directly?

A: Functional replacement is possible. Both devices share 2Kbit capacity, 256 x 8 organization, I2C interface, and 5 ms write cycle time. AT24C02D-XHM-B operates at 1 MHz (versus 400 kHz) with 4.5 µs access time (versus 900 ns), representing performance enhancement. Voltage range differs (1.7V ~ 3.6V versus 1.5V ~ 3.6V), and operating temperature extends to -40°C (versus -20°C). Package type differs (8-TSSOP versus 8-MSOP), requiring PCB layout modification.

Q: What is the difference between BR24G02FVM-3GTTR and 24VL024HT/MS?

A: Both operate at 400 kHz with 2Kbit capacity and I2C interface. BR24G02FVM-3GTTR offers extended voltage range (1.6V ~ 5.5V versus 1.5V ~ 3.6V) and extended operating temperature (-40°C ~ 85°C versus -20°C ~ 85°C). Both use 8-MSOP packaging. BR24G02FVM-3GTTR is manufactured by Rohm Semiconductor and maintains active product status.

Q: Are 8-TSSOP and 8-MSOP packages interchangeable?

A: No. While both are 8-pin surface mount packages, they have different physical dimensions and pinout configurations. 8-MSOP measures 0.118" width (3.00mm), while 8-TSSOP measures 0.173" width (4.40mm). PCB footprint redesign is required when switching between these package types.

Q: Which substitute offers the widest voltage operating range?

A: BR24G02 series parts (BR24G02FVM-3GTTR, BR24G02FVJ-3AGTE2, BR24G02FVT-3AGE2, BR24G02FVT-3GE2) and BR24L02 series parts (BR24L02FVM-WTR) operate across 1.6V ~ 5.5V or 1.8V ~ 5.5V, compared to the original part's 1.5V ~ 3.6V range.

Q: Can I use a 1 MHz part in a 400 kHz application?

A: Yes. Higher clock frequency operation is backward compatible with lower frequency requirements. AT24C02D-XHM-B and AT24C02D-XHM-T (1 MHz capable) function correctly in 400 kHz systems. The I2C bus will operate at the lower frequency determined by the system master controller.

Q: What does "Not For New Designs" status mean?

A: Parts marked "Not For New Designs" are in mature or declining production phases. While functionally available, they should not be selected for new product development. Use these parts only for legacy system support or when existing inventory must be consumed.
