Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25LC080-I/P are qualified based on the following critical parameters:

Memory Capacity & Organization: All substitutes maintain 8Kbit capacity with 1K x 8 organization, ensuring identical data storage and addressing schemes.

Interface Protocol: SPI interface is maintained across all substitutes, guaranteeing protocol-level compatibility with existing circuit designs.

Package & Mounting: All substitutes use 8-DIP (0.300", 7.62mm) through-hole packaging, enabling direct socket or PCB replacement without layout modifications.

Operating Temperature Range: All substitutes support -40°C to 85°C operating range, matching the thermal specifications of the main part.

Write Cycle Time: All substitutes maintain 5ms write cycle time, preserving timing characteristics for memory operations.

Supply Voltage Compatibility: Substitutes are grouped by voltage range. The 25LC080-I/P operates at 2.5V ~ 5.5V. Substitutes with 1.8V ~ 5.5V range (25AA080A-I/P, 25AA080B-I/P) provide extended low-voltage capability and are fully compatible in 2.5V ~ 5.5V applications. Substitutes with 2.5V ~ 5.5V range (25LC080B-I/P, 25LC080D-I/P) match the original specification exactly.

Clock Frequency: The main part operates at 2 MHz. Substitutes operating at 10 MHz provide higher performance while maintaining backward compatibility in 2 MHz applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Verified Programmability)

The 25LC080B-I/P and 25AA080A-I/P are manufacturer-recommended substitutes with verified programmability status. Both maintain full RoHS3 compliance and Active product status. The 25LC080B-I/P matches the original voltage specification (2.5V ~ 5.5V) while providing 10 MHz clock frequency. The 25AA080A-I/P extends the low-voltage operating range to 1.8V while maintaining compatibility in standard 2.5V ~ 5.5V applications.

Secondary Substitute (Verified Programmability)

The 25AA080B-I/P provides identical electrical and thermal specifications to the 25AA080A-I/P with verified programmability and Active product status.

Alternative Substitute (Unverified Status)

The 25LC080D-I/P matches the voltage and frequency specifications of the 25LC080B-I/P but carries unverified programmability status and not-applicable moisture sensitivity level designation. This part remains suitable for applications where verification status is not a procurement requirement.

All substitutes maintain identical memory organization, SPI interface, package dimensions, and write cycle timing, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 25AA080A-I/P and 25AA080B-I/P be used interchangeably with 25LC080-I/P?

A: Yes. Both parts maintain 8Kbit SPI EEPROM architecture, 8-DIP through-hole packaging, and -40°C to 85°C operating range. The 25AA080 series operates at 10 MHz versus the 2 MHz specification of 25LC080-I/P, providing performance headroom. The extended 1.8V low-voltage range is fully compatible in 2.5V ~ 5.5V applications.

Q: What is the difference between 25LC080B-I/P and 25LC080D-I/P?

A: Both parts share identical electrical specifications: 8Kbit capacity, 10 MHz clock frequency, 2.5V ~ 5.5V supply range, and 8-DIP packaging. The primary difference is programmability verification status. The 25LC080B-I/P carries verified programmability certification, while 25LC080D-I/P does not.

Q: Are there voltage compatibility concerns when substituting 25AA080 series parts?

A: No. The 25AA080A-I/P and 25AA080B-I/P operate across 1.8V ~ 5.5V, which encompasses the original 2.5V ~ 5.5V range. These parts are fully compatible in any application designed for 25LC080-I/P voltage specifications.

Q: Does clock frequency difference affect circuit compatibility?

A: No. The 10 MHz substitutes (25AA080A-I/P, 25AA080B-I/P, 25LC080B-I/P, 25LC080D-I/P) operate at higher frequency than the 2 MHz original specification. Higher clock frequency provides performance margin and is backward compatible with 2 MHz circuit designs.

Q: Can these parts be used in new designs or only as replacements?

A: All substitute parts maintain Active product status with current manufacturing availability. They are suitable for both replacement applications and new circuit designs.

Q: What compliance certifications apply to all substitutes?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.32.0051.
