24VL025/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24VL025/P is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, designed for non-volatile data storage applications requiring low-voltage operation. This through-hole 8-DIP package device operates at 400 kHz I2C clock frequency with 900 ns access time and supports supply voltages from 1.5V to 3.6V. The part is currently in active production status and ROHS3 compliant. Equivalent and substitute parts are identified for applications where alternative sourcing, extended temperature ranges, or higher clock frequency operation may be required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24VL025/P are classified based on the following substitution criteria:

Parametric Equivalent (24VL024H/P): Maintains identical electrical and mechanical specifications including 2Kbit memory size, 256 x 8 organization, I2C interface, 400 kHz clock frequency, 900 ns access time, 1.5V ~ 3.6V supply voltage range, and 8-DIP through-hole package. This part provides direct functional equivalence with no performance trade-offs.

Manufacturer Recommended Substitute (AT24C02D-PUM): Shares core memory architecture (2Kbit, 256 x 8, I2C interface, 8-DIP package) but operates at higher clock frequency (1 MHz versus 400 kHz) and faster access time (4.5 µs versus 900 ns). Supply voltage range is slightly narrower (1.7V ~ 3.6V versus 1.5V ~ 3.6V). Operating temperature range is extended to -40°C ~ 85°C. This part is suitable for applications requiring higher speed operation or extended low-temperature performance.

Parameter Comparison

Engineering Selection Recommendations

24VL024H/P Selection: Use this parametric equivalent when direct replacement is required with identical electrical performance. Both parts maintain ROHS3 compliance and REACH unaffected status. This part is suitable for applications where the original 24VL025/P specification must be preserved without modification.

AT24C02D-PUM Selection: Use this manufacturer-recommended substitute when extended low-temperature operation (-40°C minimum) is required or when higher I2C clock frequency (1 MHz) operation is beneficial. The narrower minimum supply voltage (1.7V versus 1.5V) must be evaluated against system power supply specifications. All three parts maintain equivalent RoHS and REACH compliance status, supporting regulatory requirements across automotive, industrial, and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can 24VL024H/P be used as a direct replacement for 24VL025/P? A: Yes. The 24VL024H/P is a parametric equivalent with identical memory capacity, I2C interface, clock frequency, access time, supply voltage range, operating temperature range, and 8-DIP package configuration. No circuit modifications are required.

Q: What are the key differences between 24VL025/P and AT24C02D-PUM? A: The AT24C02D-PUM operates at 1 MHz I2C clock frequency compared to 400 kHz, has faster access time (4.5 µs versus 900 ns), supports extended low-temperature operation (-40°C minimum versus -20°C), and requires minimum supply voltage of 1.7V versus 1.5V. Memory capacity and package remain identical.

Q: Is the AT24C02D-PUM backward compatible with 24VL025/P? A: The AT24C02D-PUM is electrically compatible at the I2C interface level and shares the same 8-DIP package footprint. However, the minimum supply voltage specification (1.7V) must be verified against system design. The higher clock frequency capability does not create incompatibility with 400 kHz I2C bus operation.

Q: Are all three parts suitable for the same PCB layout? A: Yes. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole package configuration and pin assignments, allowing direct PCB footprint compatibility without layout modifications.

Q: Do all substitute parts maintain the same compliance certifications? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications requiring these certifications.
