AT25M02-SSHD-T Equivalent & Substitute Parts

Part Overview

The AT25M02-SSHD-T is a 2Mbit EEPROM memory IC manufactured by Microchip Technology, designed for SPI serial interface applications. This non-volatile memory device operates at 5 MHz clock frequency with a 10ms write cycle time and supports supply voltages from 2.5V to 5.5V. The component is housed in an 8-SOIC surface mount package and maintains active product status with ROHS3 compliance. Substitute parts are identified when equivalent memory capacity, interface protocol, package form factor, and voltage specifications align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25M02-SSHD-T is determined by the following critical parameters:

• Memory capacity of 2Mbit with 256K x 8 organization
• SPI serial interface protocol
• 8-SOIC surface mount package with 0.154" width (3.90mm)
• Supply voltage range compatibility of 2.5V ~ 5.5V
• Non-volatile EEPROM technology

The M95M02-DWMN3TP/K from STMicroelectronics qualifies as a manufacturer-recommended substitute. While this part operates at 10 MHz clock frequency (double the AT25M02-SSHD-T) and features a 5ms write cycle time (half the original), it maintains identical memory capacity, organization, SPI interface, package form factor, and voltage supply range. The enhanced performance characteristics of the M95M02-DWMN3TP/K do not create incompatibility; rather, they provide operational headroom in timing-critical applications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25M02-SSHD-T and M95M02-DWMN3TP/K maintain active product status and ROHS3 compliance. The M95M02-DWMN3TP/K carries automotive-grade qualification with AEC-Q100 certification and extends the operating temperature range to -40°C ~ 125°C, compared to the standard-grade AT25M02-SSHD-T range of -40°C ~ 85°C. Selection between these parts depends on application temperature requirements and automotive qualification necessity. Both parts are functionally interchangeable at the memory interface level due to identical SPI protocol implementation, memory organization, and package specifications.

Frequently Asked Questions (FAQ)

Q: Can the M95M02-DWMN3TP/K directly replace the AT25M02-SSHD-T in existing designs?

A: Yes. Both parts implement identical SPI interface protocols, memory organization (256K x 8), and 8-SOIC package form factors. Pin-to-pin compatibility is maintained. The M95M02-DWMN3TP/K's higher clock frequency (10 MHz vs. 5 MHz) and faster write cycle time (5ms vs. 10ms) do not create backward compatibility issues.

Q: What are the key differences between these two parts?

A: The M95M02-DWMN3TP/K operates at twice the clock frequency, features half the write cycle time, supports an extended temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C), and carries automotive-grade qualification with AEC-Q100 certification. The AT25M02-SSHD-T is a standard-grade component.

Q: Are there package or footprint differences?

A: No. Both parts use the 8-SOIC package with identical 0.154" width (3.90mm). PCB footprints are interchangeable.

Q: Which part should be selected for automotive applications?

A: The M95M02-DWMN3TP/K is qualified for automotive use with AEC-Q100 certification and is the appropriate choice for automotive-grade designs.

Q: Do both parts support the same supply voltage range?

A: Yes. Both parts operate across the 2.5V ~ 5.5V supply voltage range.
