Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25AA080CT-I/SN is determined by the following criteria:

Primary Compatibility Parameters:

• Memory capacity: 8Kbit
• Memory organization: 1K x 8
• Interface protocol: SPI
• Package type: 8-SOIC with 0.154" (3.90mm) width
• Supply voltage range: Minimum 1.8V, maximum 5.5V
• Operating temperature range: Minimum -40°C, maximum 85°C

Secondary Compatibility Parameters:

• Clock frequency: 10 MHz or higher
• Write cycle time: 5ms or faster
• RoHS compliance status

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Specifications): Parts with matching clock frequency (10 MHz), write cycle time (5ms), voltage range (1.8V ~ 5.5V), and temperature range (-40°C ~ 85°C).

Enhanced Substitutes (Higher Performance): Parts with higher clock frequency (20 MHz) or faster write cycle time (4ms), which operate within the same voltage and temperature envelope, providing backward compatibility with designs specified for the 25AA080CT-I/SN.

Parameter Comparison

Engineering Selection Recommendations

Microchip Technology 25AA080 Series (Direct Compatibility): 25AA080C-I/SN, 25AA080AT-I/SN, and AT25080B-SSHL-B/T are Microchip products with Active product status and verified programmability. These parts maintain identical memory specifications and package dimensions. Selection between tube and tape & reel packaging depends on assembly process requirements. AT25080B variants offer 20 MHz operation for applications requiring higher clock frequencies while maintaining backward compatibility.

STMicroelectronics M95080 Series (Enhanced Performance): M95080-DRMN3TP/K, M95080-DRMN8TP/K, M95080-RMN6TP, and M95080-WMN6TP provide 20 MHz clock frequency with 4ms write cycle time. M95080-DRMN3TP/K and M95080-DRMN8TP/K include AEC-Q100 automotive qualification with extended temperature range (-40°C ~ 125°C and -40°C ~ 105°C respectively). M95080-WMN6TP operates with 2.5V minimum supply voltage. All M95080 variants are Active status with ROHS3 compliance.

Rohm Semiconductor BR25H080F-2CE2: This part provides 10 MHz operation with 4ms write cycle time and AEC-Q100 automotive qualification. Operating temperature range extends to 125°C. Minimum supply voltage is 2.5V. Active product status with ROHS3 compliance.

onsemi CAT25080VI-GT3: Provides 8Kbit SPI EEPROM in 8-SOIC package with 1.8V ~ 5.5V supply range and -40°C ~ 85°C operating temperature. Active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 20 MHz part as a substitute for the 10 MHz 25AA080CT-I/SN?

A: Yes. Parts with higher clock frequency (20 MHz) are backward compatible with designs specified for 10 MHz operation. The 25AA080CT-I/SN will operate correctly with higher-frequency substitutes such as AT25080B-SSHL-B/T, M95080-DRMN3TP/K, M95080-RMN6TP, and M95080-WMN6TP.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is used for manual assembly or small-volume production. Tape & reel and cut tape & digi-reel packaging are used for automated pick-and-place assembly. Selection depends on manufacturing process requirements. Electrical and functional specifications remain identical across packaging types.

Q: Are automotive-qualified parts (AEC-Q100) compatible with commercial applications?

A: Yes. Automotive-qualified parts such as BR25H080F-2CE2, M95080-DRMN3TP/K, and M95080-DRMN8TP/K meet higher reliability and temperature range standards and are suitable for both automotive and commercial applications.

Q: What is the minimum supply voltage requirement for substitution?

A: The 25AA080CT-I/SN operates from 1.8V ~ 5.5V. Substitutes with 2.5V minimum supply voltage (BR25H080F-2CE2, M95080-WMN6TP) are compatible with designs operating above 2.5V. For designs requiring 1.8V operation, use substitutes with 1.8V minimum specification.

Q: Can I substitute a part with extended temperature range?

A: Yes. Parts with extended operating temperature range (-40°C ~ 125°C or -40°C ~ 105°C) are compatible with designs specified for -40°C ~ 85°C operation. The extended range provides additional margin for high-temperature environments.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the 25AA080CT-I/SN.
