BR25L080FVT-WE2 Equivalent & Substitute Parts

Part Overview

The BR25L080FVT-WE2 is an 8Kbit EEPROM memory IC manufactured by Rohm Semiconductor, featuring SPI interface operation at 5 MHz with 8-TSSOP-B surface mount packaging. This device is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where continued component availability is required.

Substitute Part Grouping Explanation

Substitution for the BR25L080FVT-WE2 is determined by strict equivalence across the following critical parameters:

Memory capacity: 8Kbit (1K x 8 organization)
Interface protocol: SPI
Package form factor: 8-TSSOP with 0.173" width and 4.40mm width specification
Supply voltage range: Minimum 1.8V to maximum 5.5V compatibility
Operating temperature range: -40°C to 85°C minimum
Write cycle time: 5ms maximum
Surface mount technology
RoHS3 compliance

Clock frequency operates at 5 MHz on the main part. Substitute parts operating at 10 MHz are functionally compatible, as higher clock frequency capability does not restrict operation at lower speeds. All substitute candidates maintain identical memory organization, SPI protocol, package dimensions, voltage specifications, and temperature ratings.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Microchip Technology and carry Active product status, ensuring long-term availability and ongoing manufacturing support. Each substitute maintains full electrical and mechanical compatibility with the BR25L080FVT-WE2 across memory capacity, SPI interface, package form factor, and core operating specifications.

The 25AA080 series (25AA080A-I/ST, 25AA080AT-I/ST, 25AA080BT-I/ST, 25AA080C-I/ST, 25AA080CT-I/ST, 25AA080D-I/ST, 25AA080DT-I/ST) operates at 10 MHz clock frequency with 1.8V to 5.5V supply voltage range, directly matching the original part's voltage specification and exceeding its 5 MHz requirement. These parts are ROHS3 compliant and available in both Tube and Tape & Reel packaging options.

The 25LC080 series (25LC080AT-I/ST, 25LC080BT-E/ST, 25LC080C-E/ST) operates at 10 MHz with a narrower supply voltage range of 2.5V to 5.5V. These parts are suitable for applications where the minimum supply voltage requirement of 2.5V is acceptable. The 25LC080BT-E/ST and 25LC080C-E/ST variants support extended operating temperature to 125°C, providing additional thermal margin for demanding environments.

For applications requiring Tape & Reel packaging to match the original BR25L080FVT-WE2 format, select from: 25AA080AT-I/ST, 25AA080BT-I/ST, 25AA080CT-I/ST, 25AA080DT-I/ST, 25LC080AT-I/ST, 25LC080BT-E/ST.

For applications where Tube packaging is acceptable, Tube variants offer equivalent electrical performance with potentially different inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 MHz part as a direct replacement for the 5 MHz BR25L080FVT-WE2?

A: Yes. The substitute parts operate at 10 MHz maximum clock frequency, which is a superset capability. The SPI interface allows operation at any frequency up to the device maximum, so 10 MHz-rated parts function correctly when clocked at 5 MHz or lower.

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

A: The primary difference is supply voltage range. The 25AA080 series supports 1.8V to 5.5V, matching the original BR25L080FVT-WE2 specification. The 25LC080 series supports 2.5V to 5.5V, with a higher minimum voltage requirement. Select 25AA080 for applications requiring 1.8V operation; select 25LC080 only if your system operates at 2.5V or higher.

Q: Does packaging type (Tube vs. Tape & Reel) affect electrical performance?

A: No. Tube and Tape & Reel packaging contain identical die and electrical specifications. Packaging type affects only handling, storage, and automated assembly compatibility. Select based on your manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original BR25L080FVT-WE2 environmental standard.

Q: Can I substitute a part with extended temperature range (25LC080BT-E/ST, 25LC080C-E/ST operating to 125°C) in place of the standard -40°C to 85°C part?

A: Yes. Extended temperature capability is a superset of the original specification. Parts rated to 125°C operate correctly within the -40°C to 85°C range required by the original part.

Q: What inventory levels are available for these substitutes?

A: Inventory varies by part number. 25AA080CT-I/ST offers the highest stock level at 8,216 pieces. 25AA080C-I/ST provides 3,205 pieces. Other variants range from 698 to 1,741 pieces. Verify current availability with your supplier for production quantities.

Q: Is the 8-TSSOP package physically identical between BR25L080FVT-WE2 and Microchip substitutes?

A: Yes. All parts use 8-TSSOP package with 0.173" width and 4.40mm width specification, ensuring identical PCB footprint and pin compatibility.
