25AA080-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25AA080-I/P is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 1 MHz clock frequency with a supply voltage range of 1.8V to 5.5V and is housed in an 8-pin DIP package. The device is Active product status and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory management, or component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25AA080-I/P are qualified based on the following criteria:

Critical Parameters (Must Match):

• Memory Size: 8Kbit
• Memory Organization: 1K x 8
• Memory Interface: SPI
• Package Type: 8-DIP (0.300", 7.62mm)
• Supply Voltage Range: 1.8V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Write Cycle Time: 5ms
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed Differences):

• Clock Frequency: Substitute parts may operate at higher clock frequencies (10 MHz) while maintaining backward compatibility with 1 MHz applications

The 25AA080A-I/P and 25AA080B-I/P are qualified substitutes because they maintain all critical electrical and mechanical parameters while offering enhanced clock frequency performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—25AA080-I/P, 25AA080A-I/P, and 25AA080B-I/P—maintain Active product status and full RoHS3 compliance. The 25AA080A-I/P and 25AA080B-I/P are direct substitutes with identical electrical and mechanical specifications to the 25AA080-I/P, with the exception of increased clock frequency capability (10 MHz versus 1 MHz). This enhanced frequency performance provides additional operational margin without compromising compatibility with existing 1 MHz system designs. All parts share identical package geometry, pin configuration, voltage specifications, and temperature operating range, enabling direct substitution in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 25AA080A-I/P or 25AA080B-I/P be used as direct replacements for the 25AA080-I/P?

A: Yes. Both substitute parts are electrically and mechanically compatible. They maintain identical memory capacity, organization, interface protocol, supply voltage range, operating temperature range, and 8-DIP package specifications. The higher clock frequency (10 MHz) of the substitute parts does not prevent operation in 1 MHz applications.

Q: What is the primary difference between the 25AA080-I/P and its substitutes?

A: The primary difference is clock frequency. The 25AA080-I/P operates at 1 MHz, while the 25AA080A-I/P and 25AA080B-I/P operate at 10 MHz. All other electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the same 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration and mechanical dimensions.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

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

A: Yes. The substitute parts can be used interchangeably with the 25AA080-I/P in through-hole PCB designs without requiring circuit modifications or layout changes.
