Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080C-I/P is determined by the following critical parameters:

• Memory capacity: 8Kbit (1K x 8 organization)
• Serial interface: SPI protocol
• Operating frequency: 10 MHz
• Write cycle time: 5ms
• Package: 8-DIP through-hole form factor
• Operating temperature range: -40°C ~ 85°C

Substitute parts must maintain identical values across all these parameters. Voltage supply range variations are permitted when the substitute part's range encompasses or exceeds the original specification. All identified substitutes are manufactured by Microchip Technology and share the same base functionality within the 25LC080 and 25AA080 product families.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the 25LC080C-I/P. Selection among substitutes should be based on the following factors:

25LC080B-I/P and 25LC080D-I/P: These parts belong to the 25LC080 family with identical voltage supply specifications (2.5V ~ 5.5V) as the main part. The 25LC080B-I/P carries verified programmability status. The 25LC080D-I/P is available with higher inventory levels.

25AA080A-I/P and 25AA080B-I/P: These parts belong to the 25AA080 family and feature an extended lower voltage limit (1.8V ~ 5.5V), providing broader supply voltage compatibility. Both parts carry verified programmability status. These options are suitable for applications requiring operation at voltages below 2.5V.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can 25AA080A-I/P or 25AA080B-I/P be used in place of 25LC080C-I/P?

A: Yes. Both parts maintain identical memory capacity (8Kbit), organization (1K x 8), SPI interface, clock frequency (10 MHz), write cycle time (5ms), operating temperature range (-40°C ~ 85°C), and 8-DIP package specifications. The 25AA080 family supports a lower minimum supply voltage (1.8V versus 2.5V), making them suitable for applications operating across the full 1.8V to 5.5V range.

Q: What is the difference between 25LC080 and 25AA080 product families?

A: The primary difference is the minimum supply voltage specification. The 25LC080 family operates from 2.5V to 5.5V, while the 25AA080 family operates from 1.8V to 5.5V. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts pin-compatible with the original 25LC080C-I/P?

A: Yes. All substitute parts use the same 8-DIP through-hole package with 0.300" (7.62mm) spacing, ensuring direct pin-for-pin compatibility on PCBs designed for the 25LC080C-I/P.

Q: Does programmability verification status affect functional compatibility?

A: Programmability verification indicates that the part has been tested and confirmed by DiGi-Electronics. Parts marked as "Not Verified" remain functionally equivalent but have not undergone this specific verification process. Selection should be based on application requirements and quality assurance protocols.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary among substitute parts. Current availability should be confirmed with the supplier for production planning purposes, though all listed parts are in active production status.
