Microchip 25AA080C-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The Microchip 25AA080C-I/P is an 8Kbit EEPROM memory integrated circuit designed for non-volatile data storage applications requiring SPI serial interface communication. This device operates at 10 MHz clock frequency with supply voltage range of 1.8V to 5.5V and is housed in an 8-DIP through-hole package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for equivalent functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25AA080C-I/P are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Memory capacity: 8Kbit
• Memory organization: 1K x 8 bit structure
• Interface protocol: SPI serial communication
• Clock frequency: 10 MHz maximum
• Write cycle time: 5ms per word/page
• Supply voltage range: 1.8V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package format: 8-DIP through-hole configuration
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The substitute parts 25AA080A-I/P and 25AA080B-I/P meet all these criteria and are manufactured by Microchip Technology under the same base product number 25AA080. These parts are direct functional equivalents suitable for board-level replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

All three parts—25AA080C-I/P, 25AA080A-I/P, and 25AA080B-I/P—are active production devices from Microchip Technology with identical electrical specifications and mechanical packaging. Selection among these parts may be based on inventory availability and supply chain considerations. The 25AA080A-I/P and 25AA080B-I/P are both verified as programmable through DiGi-Electronics, while the 25AA080C-I/P status is not verified. All parts carry ROHS3 compliance, REACH Unaffected status, and EAR99 export classification, making them suitable for equivalent applications without regulatory or compliance concerns.

Frequently Asked Questions (FAQ)

Q: Can 25AA080A-I/P or 25AA080B-I/P be used as direct replacements for 25AA080C-I/P?

A: Yes. All three parts are functionally equivalent across memory capacity, interface protocol, electrical specifications, and package format. Direct board-level substitution is supported without circuit modification.

Q: Are there any differences in the 8-DIP package dimensions between these parts?

A: No. All three parts use identical 8-DIP packaging with 0.300" (7.62mm) body dimensions and through-hole mounting configuration.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. The 25AA080A-I/P and 25AA080B-I/P maintain identical ROHS3 compliance, REACH Unaffected status, and EAR99 classification as the 25AA080C-I/P.

Q: What is the significance of the A, B, and C designations in the part numbers?

A: The A, B, and C designations represent different production variants within the 25AA080 base product family. All variants meet the same functional and electrical specifications for 8Kbit SPI EEPROM operation.

Q: Is the SPI interface protocol identical across all three parts?

A: Yes. All parts implement the same SPI serial interface with 10 MHz clock frequency and 5ms write cycle time specifications.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The identical 8-DIP package footprint and pin configuration allow direct PCB-level interchangeability without layout modifications.
