25LC080BT-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC080BT-E/SN is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 10 MHz with a supply voltage range of 2.5V to 5.5V and is housed in an 8-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when enhanced performance specifications (such as higher clock frequency or extended temperature ranges) are needed for specific applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080BT-E/SN is determined by the following critical parameters:

Primary Substitution Criteria:

Memory capacity: 8Kbit (1K x 8 organization)
Interface protocol: SPI
Package footprint: 8-SOIC with 0.154" (3.90mm) width
Supply voltage compatibility: Minimum 2.5V support required

Engineering Selection Recommendations

Direct Pin-Compatible Substitutes (Identical Package, Same or Enhanced Specifications):

The 25LC080DT-E/SN is the primary direct substitute, offering identical electrical and thermal specifications with the same 8-SOIC package footprint. Both parts maintain active production status and ROHS3 compliance.

The M95080-DRMN3TP/K and M95080-WMN6TP provide enhanced clock frequency (20 MHz) while maintaining the 8-SOIC package and 8Kbit capacity. M95080-DRMN3TP/K extends the operating temperature range to -40°C ~ 125°C and includes AEC-Q100 automotive qualification. M95080-WMN6TP maintains the same supply voltage range as the original part (2.5V ~ 5.5V).

Alternative Package Substitutes (Different Footprint, Equivalent Specifications):

The BR25H080F-2CE2 and BR25H080FJ-2CE2 from Rohm Semiconductor provide equivalent 8Kbit SPI EEPROM functionality in 8-SOP and 8-SOP-J packages respectively. Both include AEC-Q100 automotive qualification and maintain the -40°C ~ 125°C operating range. These parts require PCB layout modification due to different package dimensions (0.173" vs 0.154" width).

Not Recommended for New Designs:

The BR25L080F-WE2 is designated "Not For New Designs" and should not be selected for new applications despite functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 25LC080DT-E/SN be used as a direct replacement for the 25LC080BT-E/SN?

A: Yes. Both parts are manufactured by Microchip Technology with identical memory capacity (8Kbit), SPI interface, clock frequency (10 MHz), supply voltage range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and 8-SOIC package specifications. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel).

Q: What is the advantage of using M95080-DRMN3TP/K over the original 25LC080BT-E/SN?

A: The M95080-DRMN3TP/K operates at 20 MHz clock frequency (double the original 10 MHz), features a faster 4ms write cycle time, and includes AEC-Q100 automotive qualification. It maintains the same 8-SOIC package footprint and extends the operating temperature range to -40°C ~ 125°C. Supply voltage compatibility is 1.8V ~ 5.5V.

Q: Are the Rohm BR25H080 series parts pin-compatible with the 25LC080BT-E/SN?

A: The BR25H080F-2CE2 and BR25H080FJ-2CE2 are functionally equivalent but use different package variants (8-SOP and 8-SOP-J) with different physical dimensions (0.173" width vs. 0.154" width). While pin count and signal assignments are compatible, PCB layout modifications are required. Both parts maintain 8Kbit capacity, SPI interface, 10 MHz operation, and -40°C ~ 125°C temperature range.

Q: What is the difference between M95080-WMN6TP and M95080-RMN6TP?

A: Both parts are STMicroelectronics M95080 variants with 20 MHz clock frequency and 8-SOIC package. M95080-WMN6TP supports 2.5V ~ 5.5V supply voltage, while M95080-RMN6TP supports 1.8V ~ 5.5V. Operating temperature range differs: M95080-WMN6TP operates -40°C ~ 85°C, while M95080-RMN6TP operates -40°C ~ 85°C. Packaging format differs (Tube vs. Cut Tape & Digi-Reel).

Q: Can I use CAT25080VI-GT3 as a substitute?

A: The CAT25080VI-GT3 from onsemi provides 8Kbit SPI EEPROM in an 8-SOIC package with 1.8V ~ 5.5V supply voltage and -40°C ~ 85°C operating range. Clock frequency is not specified in available documentation. The lower operating temperature maximum (-85°C vs. -125°C) and unspecified clock frequency may limit suitability for applications requiring the original part's full temperature range or 10 MHz minimum performance.

Q: Why is BR25L080F-WE2 marked "Not For New Designs"?

A: Parts designated "Not For New Designs" are in end-of-life status or have been superseded by newer alternatives. While functionally equivalent, they should not be selected for new product development. Existing designs using this part should evaluate migration to active alternatives such as BR25H080F-2CE2 or M95080 series.
