Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance: AT25080B-SSHL-T and M95080-WMN6TP are suitable substitutes when higher clock frequency (20 MHz) and faster write cycles (5ms) are acceptable. Both maintain 8-SOIC packaging and ROHS3 compliance. AT25080B-SSHL-T offers unlimited moisture sensitivity level (MSL 1) in Cut Tape & Digi-Reel packaging with verified DiGi-Electronics programmability. M95080-WMN6TP maintains the 2.5V ~ 5.5V supply voltage range of the original part.

For Automotive Applications: BR25H080FJ-2CE2 is the appropriate selection when AEC-Q100 automotive qualification is required. This part maintains 8-SOIC packaging, ROHS3 compliance, and supports the full -40°C to 125°C operating range with 10 MHz operation.

For Low-Voltage Applications: CAT25080VI-GT3 and AT25080B-SSHL-B support 1.8V minimum supply voltage, enabling operation in low-power designs. Both are ROHS3 compliant with -40°C to 85°C operating range.

For Supply Chain Continuity: Multiple manufacturers are represented among substitutes (Microchip Technology, STMicroelectronics, Rohm Semiconductor, onsemi), providing design flexibility and reducing single-source dependency.

Frequently Asked Questions (FAQ)

Q: Can AT25080B-SSHL-T replace 25LC080CT-H/SN in all applications?

A: AT25080B-SSHL-T is compatible for applications where the operating temperature range of -40°C to 85°C is acceptable. The original part supports -40°C to 150°C. Both parts share 8-SOIC packaging, 8Kbit capacity, SPI interface, and ROHS3 compliance. The substitute offers higher clock frequency (20 MHz vs 5 MHz) and faster write cycles (5ms vs 6ms).

Q: What is the difference between BR25H080F-2CE2 and BR25H080FJ-2CE2?

A: Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (8Kbit, 10 MHz, 4ms write cycle, 2.5V ~ 5.5V supply, -40°C ~ 125°C operation, AEC-Q100 qualification). The primary difference is package form factor: BR25H080F-2CE2 uses 8-SOP (0.173", 4.40mm width) while BR25H080FJ-2CE2 uses 8-SOIC (0.154", 3.90mm width). BR25H080FJ-2CE2 matches the original part's 8-SOIC package.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant, matching the compliance status of the original 25LC080CT-H/SN.

Q: Which substitute offers the lowest minimum supply voltage?

A: AT25080B-SSHL-B, AT25080B-SSHL-T, CAT25080VI-GT3, and M95080-RMN6TP all support 1.8V minimum supply voltage, compared to 2.5V for the original part and M95080-WMN6TP.
