Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 25LC080C-H/SN. Selection among substitutes depends on specific application requirements:

For applications requiring extended operating temperature range (-40°C to 150°C), the 25LC080C-H/SN remains the only option among listed parts.

For automotive-grade applications with AEC-Q100 qualification, BR25H080F-2CE2, BR25H080FJ-2CE2, and M95080-DRMN3TP/K are available.

For applications with lower voltage supply requirements (1.8V minimum), AT25080B-SSHL-B, AT25080B-SSHL-T, CAT25080VI-GT3, M95080-DRMN3TP/K, M95080-RMN6TP, and R1EX25008ASA00I#S0 accommodate 1.8V operation.

For higher clock frequency operation (20 MHz), AT25080B-SSHL-B, AT25080B-SSHL-T, M95080-DRMN3TP/K, M95080-RMN6TP, and M95080-WMN6TP are suitable.

Package dimensions must be verified during PCB layout. BR25H080F-2CE2 and BR25H080F-2LBH2 feature 0.173" (4.40mm) width, differing from the standard 0.154" (3.90mm) width of the main part.

Frequently Asked Questions (FAQ)

Q: Can BR25H080F-2CE2 be used as a direct replacement for 25LC080C-H/SN?

A: BR25H080F-2CE2 is functionally compatible for 8Kbit SPI EEPROM applications but has a different package width (0.173" vs 0.154"). PCB layout verification is required before substitution.

Q: What is the primary difference between AT25080B-SSHL-B and AT25080B-SSHL-T?

A: Both parts are electrically identical 8Kbit SPI EEPROMs with 20 MHz operation. The difference is packaging format: AT25080B-SSHL-B is supplied in Tube, while AT25080B-SSHL-T is supplied in Cut Tape & Digi-Reel format.

Q: Is M95080-DRMN3TP/K suitable for applications requiring -40°C to 150°C operation?

A: No. M95080-DRMN3TP/K operates from -40°C to 125°C. For the full -40°C to 150°C range, the 25LC080C-H/SN is required.

Q: Can CAT25080VI-GT3 replace 25LC080C-H/SN in a 2.5V supply application?

A: CAT25080VI-GT3 supports 1.8V to 5.5V operation, which includes 2.5V. However, the operating temperature range is limited to -40°C to 85°C compared to the main part's -40°C to 150°C.

Q: What are the write cycle time differences among substitute parts?

A: Write cycle times range from 4ms to 6ms. Faster write cycles (4ms) are available in BR25H080F series and M95080-DRMN3TP/K. The main part specifies 6ms write cycle time.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance equivalent to the 25LC080C-H/SN.
