Equivalent & Substitute Parts for 25LC080D-E/MS

Part Overview

The 25LC080D-E/MS is an 8Kbit EEPROM memory IC manufactured by Microchip Technology, featuring SPI interface operation at 10 MHz with 1K x 8 memory organization. This device operates across a supply voltage range of 2.5V to 5.5V and supports operating temperatures from -40°C to 125°C. The part is actively produced and ROHS3 compliant, with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when designs require alternative packaging formats, higher clock frequencies, different voltage specifications, or sourcing from alternative manufacturers while maintaining core EEPROM functionality and 8Kbit capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080D-E/MS is determined by the following core parameters:

Critical Parameters (Must Match or Exceed):

• Memory Size: 8Kbit
• Memory Organization: 1K x 8
• Memory Interface: SPI
• Memory Type: Non-Volatile EEPROM

Flexible Parameters (May Vary):

• Clock Frequency: 10 MHz or higher
• Voltage Supply Range: Must encompass or exceed 2.5V ~ 5.5V
• Operating Temperature: Must support -40°C minimum and 125°C maximum, or subset thereof
• Package Type: 8-MSOP or 8-TSSOP formats acceptable
• Manufacturer: Microchip Technology, Rohm Semiconductor, onsemi, STMicroelectronics

Substitute parts are grouped by packaging format and performance characteristics. Parts with higher clock frequencies (20 MHz) are direct functional upgrades. Parts with different voltage ranges or temperature ratings require application-level verification.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Package, Same Performance): BR25H080FVM-2CTR from Rohm Semiconductor matches the 25LC080D-E/MS in 8-MSOP packaging, 10 MHz operation, and full temperature range (-40°C to 125°C). This part is AEC-Q100 qualified for automotive applications and offers 4ms write cycle time. MSL rating is 1 (Unlimited), matching the original part.

Microchip Technology Alternatives (Same Manufacturer): AT25080B-XHL-B and AT25080B-XHL-T provide 20 MHz clock frequency with 8-TSSOP packaging. Both support extended voltage range (1.8V minimum) but operate to 85°C maximum. These parts are suitable for applications not requiring the full 125°C temperature range.

Automotive-Qualified Alternatives: CAV25080YE-GT3 from onsemi provides 20 MHz operation in 8-TSSOP package with AEC-Q100 qualification, supporting the full temperature range (-40°C to 125°C) and voltage range (2.5V to 5.5V) of the original part.

STMicroelectronics Options: M95080-WDW6TP offers 20 MHz operation with verified programmability status, supporting 2.5V to 5.5V supply and -40°C to 85°C operating range in 8-TSSOP package. M95080-DFDW6TP and M95080-RDW6TP provide similar specifications with different voltage minimums (1.7V and 1.8V respectively).

Product Status Compliance: All substitute parts listed maintain Active product status and ROHS3 compliance. Selection should account for packaging format requirements (8-MSOP versus 8-TSSOP), temperature range specifications, and voltage supply constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can AT25080B-XHL-T replace 25LC080D-E/MS directly? A: AT25080B-XHL-T is functionally compatible for 8Kbit SPI EEPROM applications. The primary differences are packaging (8-TSSOP versus 8-MSOP), higher clock frequency (20 MHz versus 10 MHz), and reduced maximum operating temperature (85°C versus 125°C). PCB layout modifications are required due to package change.

Q: What is the difference between BR25H080FVM-2CTR and 25LC080D-E/MS? A: BR25H080FVM-2CTR is a Rohm Semiconductor equivalent with identical electrical specifications (10 MHz, 2.5V ~ 5.5V, -40°C ~ 125°C) and same 8-MSOP packaging. The primary advantage is AEC-Q100 automotive qualification and slightly faster write cycle time (4ms versus 5ms).

Q: Why do some substitutes have lower maximum operating temperatures? A: AT25080B-XHL-B, AT25080B-XHL-T, CAT25080YI-GT3, and STMicroelectronics M95080 variants are specified to 85°C maximum. Applications requiring operation to 125°C must use 25LC080D-E/MS, BR25H080FVM-2CTR, or CAV25080YE-GT3.

Q: Are 8-MSOP and 8-TSSOP packages interchangeable? A: No. 8-MSOP (0.118" width, 3.00mm) and 8-TSSOP (0.173" width, 4.40mm) have different footprints and pin spacing. PCB redesign is required when switching between these package types.

Q: Which substitute offers the best performance upgrade? A: CAV25080YE-GT3 and M95080-WDW6TP both provide 20 MHz operation (double the original 10 MHz) while maintaining compatibility with the 2.5V ~ 5.5V supply range. CAV25080YE-GT3 supports the full -40°C ~ 125°C temperature range with AEC-Q100 qualification.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitutes maintain MSL 1 or better ratings.
