Engineering Selection Recommendations

For Active Production Applications:

AT24C02D-XHM-B and AT24C02D-XHM-T are recommended as primary substitutes. Both maintain Microchip Technology manufacturing, RoHS3 compliance, and active product status. These parts operate at 1 MHz clock frequency, providing enhanced performance over the 400 kHz specification of the 24VL024T/MS. The extended operating temperature range (-40°C ~ 85°C) and faster access time (4.5 µs) offer operational advantages. Package variants differ: AT24C02D-XHM-B is supplied in tube packaging, while AT24C02D-XHM-T is available in cut tape and Digi-Reel formats.

For Rohm Semiconductor Alternatives:

BR24G02FVT-3GE2 and BR24G02FVM-3GTTR maintain 400 kHz clock frequency matching the original specification. Both are active products with RoHS3 compliance. BR24G02FVT-3GE2 uses 8-TSSOP packaging (0.173", 4.40mm width), while BR24G02FVM-3GTTR uses 8-MSOP packaging (0.110", 2.80mm width). The wider supply voltage range (1.6V ~ 5.5V) and extended temperature capability (-40°C ~ 85°C) provide operational flexibility.

BR24G02FVJ-3AGTE2 and BR24G02FVT-3AGE2 operate at 1 MHz and are suitable for applications requiring higher clock frequency performance. Both are active products with RoHS3 compliance and extended temperature range.

Parts Not Recommended for New Designs:

BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, BR24L02FVJ-WE2 carry "Not For New Designs" status and should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can AT24C02D-XHM-B replace 24VL024T/MS in existing designs?

A: Yes. Both parts maintain 2Kbit capacity, I2C interface, 5 ms write cycle time, and RoHS3 compliance. The AT24C02D-XHM-B operates at 1 MHz (versus 400 kHz), providing faster performance. Supply voltage range differs slightly (1.7V ~ 3.6V versus 1.5V ~ 3.6V), and operating temperature extends to -40°C. Package type changes from 8-MSOP to 8-TSSOP, requiring PCB layout modification.

Q: What is the difference between BR24G02FVM-3GTTR and 24VL024T/MS?

A: Both parts maintain identical 2Kbit capacity, I2C interface, and 400 kHz clock frequency. Key differences include manufacturer (Rohm versus Microchip), supply voltage range (1.6V ~ 5.5V versus 1.5V ~ 3.6V), and operating temperature (-40°C ~ 85°C versus -20°C ~ 85°C). Package dimensions differ: BR24G02FVM-3GTTR uses 8-MSOP (0.110", 2.80mm width) versus 24VL024T/MS (0.118", 3.00mm width).

Q: Are there packaging compatibility considerations?

A: Yes. The 24VL024T/MS uses 8-MSOP (0.118", 3.00mm width). Substitute parts use various 8-pin packages: 8-TSSOP (0.173", 4.40mm width), 8-LSSOP (0.173", 4.40mm width), and 8-MSOP variants with different widths (0.110", 2.80mm). PCB footprint verification is required before substitution.

Q: Which substitute offers the widest supply voltage range?

A: Rohm Semiconductor parts (BR24G02 and BR24L02 series) offer 1.6V ~ 5.5V or 1.8V ~ 5.5V supply ranges, compared to the original 1.5V ~ 3.6V. This extended range provides compatibility with broader system voltage requirements.

Q: Can I use a 1 MHz part in place of the 400 kHz specification?

A: Yes. I2C clock frequency is backward compatible. A 1 MHz capable device operates correctly at 400 kHz bus speeds. AT24C02D-XHM-B and AT24C02D-XHM-T support 1 MHz operation while maintaining full compatibility with 400 kHz systems.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" are in mature or end-of-life phases. While functionally equivalent, they should not be selected for new product development. Active status parts are recommended for new designs to ensure long-term supply availability.
