AT25010-10PI-2.7 Equivalent & Substitute Parts

Part Overview

The AT25010-10PI-2.7 is a 1Kbit EEPROM memory IC with SPI interface manufactured by Microchip Technology. This device is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design and procurement requirements. The part operates at 3 MHz clock frequency with a supply voltage range of 2.7V to 5.5V and is packaged in an 8-DIP through-hole configuration. Substitute parts must maintain functional compatibility while meeting current component availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

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

• Memory capacity: 1Kbit with 128 x 8 organization
• Interface protocol: SPI
• Package format: 8-DIP through-hole
• Operating temperature range: -40°C ~ 85°C
• Write cycle time: 5ms

The identified substitute parts maintain identical memory capacity, organization, interface type, package configuration, and operating temperature specifications. Clock frequency and supply voltage ranges may differ, provided the substitute operates within the original part's specified voltage window and the higher clock frequency does not create incompatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both 25AA010A-I/P and 25LC010A-I/P are active products from Microchip Technology and serve as functional equivalents to the obsolete AT25010-10PI-2.7. Selection between these substitutes should be based on the following criteria:

The 25AA010A-I/P offers the widest supply voltage range (1.8V ~ 5.5V) and is available in higher inventory quantities (6240 Pcs), making it suitable for applications requiring extended low-voltage operation or immediate procurement.

The 25LC010A-I/P operates within a narrower supply voltage range (2.5V ~ 5.5V) and is the manufacturer-recommended substitute. This part is appropriate for applications where the original 2.7V minimum supply specification is maintained.

Both substitute parts are ROHS3 compliant and REACH unaffected, addressing regulatory requirements not met by the obsolete original part. Both operate at 10 MHz clock frequency, which exceeds the original 3 MHz specification and provides enhanced performance headroom.

Frequently Asked Questions (FAQ)

Q: Can 25AA010A-I/P and 25LC010A-I/P be used interchangeably with AT25010-10PI-2.7?

A: Both parts are functionally compatible substitutes. They maintain identical memory capacity, organization, SPI interface, package configuration, and operating temperature range. The primary differences are supply voltage ranges and clock frequency. Selection depends on specific application voltage requirements.

Q: What is the significance of the higher 10 MHz clock frequency in the substitute parts?

A: The substitute parts operate at 10 MHz compared to the original 3 MHz specification. This higher frequency is backward compatible and does not create incompatibility. Applications designed for 3 MHz operation will function correctly with 10 MHz parts.

Q: Are there supply voltage compatibility concerns when substituting?

A: The original AT25010-10PI-2.7 requires 2.7V minimum supply voltage. The 25AA010A-I/P supports 1.8V minimum, providing broader compatibility. The 25LC010A-I/P requires 2.5V minimum. Both are compatible with the original 2.7V ~ 5.5V range. Verify your application's actual supply voltage against the substitute part's minimum specification.

Q: What are the compliance differences between the original and substitute parts?

A: The AT25010-10PI-2.7 is RoHS non-compliant. Both substitute parts (25AA010A-I/P and 25LC010A-I/P) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and procurement.

Q: Is the 8-DIP package identical across all three parts?

A: Yes. All three parts use the same 8-DIP (0.300", 7.62mm) through-hole package configuration, ensuring direct mechanical and electrical compatibility on existing PCB layouts.
