24LC025-E/P Equivalent & Substitute Parts

Part Overview

The 24LC025-E/P is a 2Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for I2C serial communication applications. This non-volatile memory device operates at 400 kHz clock frequency with 900 ns access time, supporting supply voltages from 2.5V to 5.5V across an extended temperature range of -40°C to 125°C. The device is housed in an 8-PDIP through-hole package and maintains Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across memory capacity, interface protocol, timing specifications, and physical packaging.

Key Parameters

Substitute Part Grouping Explanation

The 24LC02B-E/P qualifies as a parametric equivalent to the 24LC025-E/P based on strict alignment of critical substitution parameters. Both devices maintain identical memory capacity (2Kbit), memory organization (256 x 8), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), supply voltage range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and physical packaging (8-DIP through-hole). These parameters define the functional and mechanical compatibility required for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 24LC025-E/P and 24LC02B-E/P maintain Active product status from Microchip Technology with full ROHS3 compliance and REACH unaffected certification. The 24LC02B-E/P carries verified DiGi-Electronics programmable status, while the 24LC025-E/P status remains unverified. Selection between these devices should be based on application-specific programmability requirements and inventory availability. Both devices satisfy identical electrical and mechanical specifications for I2C EEPROM applications requiring 2Kbit non-volatile memory capacity.

Frequently Asked Questions (FAQ)

Q: Can the 24LC02B-E/P directly replace the 24LC025-E/P in existing circuit designs?

A: Yes. Both devices share identical memory capacity, I2C interface specifications, timing parameters, supply voltage range, operating temperature range, and 8-DIP through-hole package dimensions. No circuit modifications are required for substitution.

Q: What is the significance of the DiGi-Electronics programmable verification status?

A: The 24LC02B-E/P carries verified programmable status, indicating confirmed compatibility with DiGi-Electronics programming equipment. The 24LC025-E/P status remains unverified. This distinction may be relevant for production programming workflows but does not affect functional equivalence in end-use applications.

Q: Are there differences in memory organization between these parts?

A: No. Both devices maintain identical memory organization of 256 x 8 bits, ensuring equivalent data storage and addressing schemes.
