Equivalent & Substitute Parts for 24VL025/ST

Part Overview

The 24VL025/ST is a 2Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface with 400 kHz clock frequency and 900 ns access time. This component is actively produced and widely used in embedded systems requiring non-volatile memory storage. The part is available in 8-TSSOP surface mount packaging with ROHS3 compliance and unlimited moisture sensitivity rating.

Finding equivalent and substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements necessitate alternative voltage ranges or operating temperature specifications. The substitute parts listed maintain functional compatibility through matching memory capacity, interface protocol, and core electrical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 24VL025/ST is determined by the following critical parameters:

Primary Compatibility Criteria:

Memory capacity of 2Kbit with 256 x 8 organization
I2C serial interface protocol
5ms write cycle time
Surface mount packaging (8-TSSOP or equivalent footprint)
ROHS3 compliance

Secondary Compatibility Considerations:

Clock frequency of 400 kHz or higher
Access time of 900 ns or faster
Voltage supply range that encompasses or exceeds 1.5V ~ 3.6V
Operating temperature range that encompasses or exceeds -20°C ~ 85°C

Substitute parts are grouped into two categories: parametric equivalents from the same manufacturer (Microchip Technology) and manufacturer-recommended alternatives from Rohm Semiconductor. All listed substitutes maintain the core 2Kbit I2C EEPROM functionality with compatible pinout and electrical interface characteristics.

Engineering Selection Recommendations

Microchip Technology Parametric Equivalent: The 24VL024/ST provides direct parametric equivalence to the 24VL025/ST with identical electrical specifications, memory organization, and packaging. Both parts maintain Active product status and ROHS3 compliance. Selection between these two Microchip parts depends on inventory availability and supply chain considerations.

Rohm Semiconductor Active Status Parts: For new designs, prioritize BR24G02FVT-3AGE2, BR24G02FVT-3GE2, BR24G02FVM-3GTTR, BR24L02FVM-WTR, and BR24L02FVT-WE2, which all carry Active product status. These parts offer extended voltage supply ranges (1.6V ~ 5.5V or 1.8V ~ 5.5V) and wider operating temperature ranges (-40°C ~ 85°C) compared to the primary part. The BR24G02 series provides 1 MHz clock frequency options for applications requiring higher I2C bus speeds.

Rohm Semiconductor Legacy Parts: BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, and BR24L02FVJ-WE2 carry "Not For New Designs" status and should be used only for replacement or maintenance of existing systems. These parts remain functionally compatible but are not recommended for new product development.

Package Considerations: The 24VL025/ST uses 8-TSSOP packaging. Rohm alternatives include 8-TSSOP, 8-LSSOP, and 8-MSOP variants. Verify PCB footprint compatibility before selecting parts with different package designations.

Frequently Asked Questions (FAQ)

Q: Can I substitute BR24G02FVT-3GE2 for 24VL025/ST in an existing design? A: Yes, BR24G02FVT-3GE2 is functionally compatible. Both parts feature 2Kbit I2C EEPROM with 400 kHz clock frequency, 256 x 8 organization, and 5ms write cycle time. The Rohm part offers wider voltage (1.6V ~ 5.5V) and temperature (-40°C ~ 85°C) ranges. Verify PCB footprint compatibility, as both use 8-TSSOP packaging with identical pinout.

Q: What is the difference between BR24G02 and BR24L02 series? A: The primary difference is the minimum voltage supply specification. BR24G02 series operates from 1.6V minimum, while BR24L02 series operates from 1.8V minimum. Both maintain 2Kbit capacity and I2C interface. Select based on your system's minimum supply voltage requirement.

Q: Why do some substitute parts have "Not For New Designs" status? A: Parts marked "Not For New Designs" are in mature or end-of-life phases. Manufacturers continue production for existing customer support but do not recommend them for new product development. Use Active status parts for new designs to ensure long-term availability and support.

Q: Are all listed substitutes pin-compatible with 24VL025/ST? A: All listed parts maintain I2C EEPROM functionality with compatible pinout. However, package variants (8-TSSOP, 8-LSSOP, 8-MSOP) have different physical dimensions. Verify your PCB footprint supports the selected package type before implementation.

Q: Can I use BR24G02FVJ-3AGTE2 (1 MHz) as a direct replacement for 24VL025/ST (400 kHz)? A: Yes. The 1 MHz clock frequency is backward compatible with 400 kHz I2C bus specifications. The part operates at higher speed capability but functions correctly on slower buses. This substitution is suitable when the higher clock frequency does not conflict with system design constraints.

Q: What compliance certifications apply to all substitute parts? A: All listed parts maintain ROHS3 compliance and REACH Unaffected status, matching the primary 24VL025/ST specifications. Moisture sensitivity level is 1 (Unlimited) across all parts.
