AT25010-10PC-2.7 Equivalent & Substitute Parts

Part Overview

The AT25010-10PC-2.7 is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring SPI interface operation at 3 MHz with 8-PDIP through-hole packaging. This device is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The part operates across a 2.7V to 5.5V supply voltage range with standard industrial temperature specifications of 0°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AT25010-10PC-2.7 is determined by the following critical parameters:

• Memory capacity (1Kbit) and organization (128 x 8)
• SPI serial interface protocol
• Package form factor (8-DIP through-hole)
• Write cycle time (5ms)
• Supply voltage compatibility within the operating range

The 25AA010A-I/P qualifies as a direct substitute based on matching memory size, organization, interface type, and package specifications. While this substitute offers enhanced performance characteristics (10 MHz clock frequency, extended temperature range, and improved voltage tolerance), these represent functional improvements rather than deviations from the core substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The 25AA010A-I/P is the manufacturer-recommended substitute for the obsolete AT25010-10PC-2.7. Selection of this substitute is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance meeting current environmental and regulatory requirements
• Identical memory capacity, organization, and SPI interface specifications
• Identical write cycle time performance
• Pin-compatible 8-DIP package with matching footprint and through-hole mounting
• Extended voltage tolerance (1.8V minimum vs. 2.7V minimum) providing broader application flexibility
• Extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C) supporting wider deployment scenarios

Frequently Asked Questions (FAQ)

Q: Can the 25AA010A-I/P directly replace the AT25010-10PC-2.7 in existing designs?

A: Yes. Both devices share identical memory capacity (1Kbit), organization (128 x 8), SPI interface protocol, write cycle time (5ms), and 8-DIP package specifications. Pin compatibility and footprint alignment are confirmed.

Q: What are the differences between these parts?

A: The 25AA010A-I/P operates at 10 MHz clock frequency compared to 3 MHz for the AT25010-10PC-2.7. The substitute supports a lower minimum supply voltage (1.8V vs. 2.7V) and an extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C). The substitute is ROHS3 compliant while the original is non-compliant.

Q: Are there any compatibility concerns with the higher clock frequency?

A: The 10 MHz capability of the 25AA010A-I/P is a performance enhancement. Systems designed for 3 MHz operation remain fully compatible, as the substitute operates at the same or lower clock speeds as required by the application.

Q: Does the extended temperature range affect selection?

A: The extended temperature range of the 25AA010A-I/P (-40°C to 85°C) encompasses the original specification (0°C to 70°C). This represents an operational advantage with no compatibility impact for applications within the original temperature window.

Q: Is RoHS compliance a factor in substitution?

A: The 25AA010A-I/P meets ROHS3 compliance standards, while the AT25010-10PC-2.7 does not. For applications subject to RoHS requirements, the substitute is the appropriate selection.

Q: Are both parts available in the same packaging format?

A: Yes. Both devices use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pin configurations and footprint specifications.
