Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited), matching the BR95080-WDW6TP compliance profile. The 25LC080 series (25LC080AT-E/ST, 25LC080BT-E/ST, 25LC080CT-E/ST) provides extended operating temperature range to 125°C with voltage supply range identical to the original part (2.5V ~ 5.5V), making these direct functional replacements for standard temperature applications.

The 25AA080 series (25AA080AT-I/ST, 25AA080BT-I/ST, 25AA080CT-I/ST, 25AA080DT-I/ST) operates with lower minimum supply voltage (1.8V) and is suitable for applications requiring extended low-voltage operation. These parts maintain full compatibility with the original 2.5V ~ 5.5V supply range through their broader voltage specification.

All substitute parts operate at 10 MHz clock frequency, which exceeds the original 5 MHz specification. This higher frequency capability is backward compatible with 5 MHz system designs. All parts maintain identical 5ms write cycle time and 8-TSSOP packaging, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can 25AA080 series parts replace BR95080-WDW6TP in all applications?

A: The 25AA080 series provides functional equivalence for applications operating within the 2.5V ~ 5.5V supply range. The lower minimum voltage specification (1.8V) of the 25AA080 series does not affect compatibility in systems designed for 2.5V or higher operation. The 10 MHz clock frequency is backward compatible with 5 MHz system designs.

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

A: The primary difference is voltage supply range. The 25AA080 series operates from 1.8V ~ 5.5V, while the 25LC080 series operates from 2.5V ~ 5.5V, matching the original BR95080-WDW6TP specification. The 25LC080 series also offers extended temperature variants (-40°C ~ 125°C) in E-grade packages.

Q: Are the package dimensions identical across all substitute parts?

A: All substitute parts use 8-TSSOP packaging with identical dimensions (0.173" width, 4.40mm). PCB footprints and land patterns are directly compatible.

Q: Do all substitute parts meet RoHS3 compliance?

A: All listed substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited), matching the original part's compliance status.

Q: What does the temperature grade suffix indicate (E vs. I)?

A: The E-grade suffix indicates extended temperature operation (-40°C ~ 125°C), while the I-grade suffix indicates standard temperature operation (-40°C ~ 85°C). Select based on application temperature requirements.

Q: Is the 10 MHz clock frequency of substitute parts compatible with 5 MHz system designs?

A: Yes. The 10 MHz specification represents maximum operating frequency. Systems designed for 5 MHz operation are fully compatible with parts rated for 10 MHz, as the higher frequency capability does not impose additional requirements on the host system.
