Equivalent & Substitute Parts for 24VL025T/ST

Part Overview

The Microchip Technology 24VL025T/ST is a 2Kbit I2C EEPROM memory IC in 8-TSSOP packaging, designed for non-volatile data storage applications requiring low-voltage operation (1.5V to 3.6V). This component is currently in active production status. Substitute parts are necessary when the original part becomes unavailable, when alternative voltage ranges or operating temperatures are required, or when different package configurations better suit system integration requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 24VL025T/ST is determined by the following critical parameters:

Core Compatibility Requirements:

Memory Size: 2Kbit (256 x 8 organization)
Memory Interface: I2C protocol
Memory Type: Non-Volatile EEPROM
Write Cycle Time: 5ms
Mounting Type: Surface Mount

Voltage and Temperature Considerations: The 24VL025T/ST operates at 1.5V to 3.6V. Substitute parts with higher voltage ranges (1.6V to 5.5V or 1.8V to 5.5V) are electrically compatible and provide extended operating margins. Substitute parts with wider temperature ranges (-40°C to 85°C versus -20°C to 85°C) offer enhanced reliability in extreme environments.

Package Variations: Substitutes are grouped by package type: 8-TSSOP, 8-TSSOP-B, 8-TSSOP-BJ, 8-MSOP, and 8-SSOP-B. These packages are mechanically and electrically compatible within their respective groups, though PCB layout and footprint adjustments may be required when switching between package families.

Clock Frequency: The 24VL025T/ST operates at 400 kHz. Substitute parts operating at 1 MHz are backward compatible and provide higher data throughput capability.

Engineering Selection Recommendations

For Active Production Designs: BR24G02FVT-3GE2, BR24G02FVT-3AGE2, BR24G02FVM-3GTTR, BR24L02FVM-WTR, and BR24L02FVT-WE2 are all in Active product status and ROHS3 compliant. These parts are suitable for new designs requiring long-term supply assurance.

For Designs Requiring Extended Temperature Range: All Rohm Semiconductor substitutes operate across -40°C to 85°C, compared to the 24VL025T/ST range of -20°C to 85°C. This provides 20°C additional margin at the lower temperature extreme.

For Designs Requiring Higher Clock Frequency: BR24G02FVJ-3AGTE2 and BR24G02FVT-3AGE2 operate at 1 MHz, providing 2.5x higher data throughput than the 400 kHz baseline while maintaining full backward compatibility.

For Designs with Expanded Voltage Requirements: BR24G02 series parts (1.6V to 5.5V) and BR24L02 series parts (1.8V to 5.5V) accommodate wider supply voltage ranges than the 24VL025T/ST (1.5V to 3.6V), enabling use in systems with variable power supplies.

Package-Specific Selection: 8-TSSOP package substitutes: BR24G02FVJ-3AGTE2, BR24G02FVJ-3GTE2, BR24G02FVT-3AGE2, BR24G02FVT-3GE2, BR24L02FVJ-WE2, BR24L02FVT-WE2 8-MSOP package substitutes: BR24G02FVM-3GTTR, BR24L02FVM-WTR 8-LSSOP package substitutes: BR24G02FV-3GTE2, BR24T02FV-WGE2

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage range than the 24VL025T/ST? A: Yes. The 24VL025T/ST operates at 1.5V to 3.6V. Substitute parts rated for 1.6V to 5.5V or 1.8V to 5.5V are electrically compatible and will function correctly at the original part's voltage levels. The higher voltage rating provides additional design margin.

Q: What is the difference between 8-TSSOP, 8-TSSOP-B, and 8-TSSOP-BJ packages? A: These are variations of the thin shrink small outline package family with identical pin counts and I2C interface compatibility. PCB footprints differ slightly in body dimensions. 8-TSSOP measures 0.173" width, while 8-TSSOP-BJ measures 0.118" width. Verify footprint compatibility with your PCB design before substitution.

Q: Are parts marked "Not For New Designs" still suitable for replacement in existing products? A: Parts with "Not For New Designs" status remain functionally equivalent and are suitable for field replacement or production continuation of existing designs. However, for new product development, select parts with Active status to ensure long-term availability.

Q: Can I substitute a 1 MHz part for the 400 kHz 24VL025T/ST? A: Yes. The 1 MHz parts (BR24G02FVJ-3AGTE2, BR24G02FVT-3AGE2) are backward compatible and will operate correctly in applications designed for 400 kHz operation. The higher clock frequency provides additional performance headroom without affecting compatibility.

Q: What is the significance of the access time specification? A: The 24VL025T/ST specifies 900 ns access time. This parameter is not explicitly provided for all substitute parts in the available data. Verify access time specifications with the manufacturer datasheet if timing-critical applications require this parameter.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the 24VL025T/ST.
