25LC080D-E/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC080D-E/ST is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 10 MHz clock frequency with a supply voltage range of 2.5V to 5.5V and is housed in an 8-TSSOP surface mount package. The device is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are necessary when primary inventory is unavailable, when higher clock frequency performance is required, or when alternative manufacturer sourcing is preferred while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitution compatibility for the 25LC080D-E/ST is determined by the following critical parameters: 8Kbit memory capacity, 1K x 8 organization, SPI interface protocol, 8-TSSOP package footprint, and surface mount mounting type. All listed substitute parts maintain these core specifications. Clock frequency substitutes operate at equal or higher speeds (10 MHz or 20 MHz), ensuring backward compatibility. Supply voltage ranges must overlap with the original specification (minimum 2.5V requirement). Operating temperature range, write cycle time, and MSL rating variations are acceptable provided the substitute meets or exceeds the original device performance envelope. RoHS3 compliance and REACH unaffected status are maintained across all substitutes.

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and REACH unaffected status consistent with the original 25LC080D-E/ST specification. Selection among substitutes depends on specific application requirements:

For applications requiring extended temperature operation to 125°C, select BR25H080FVT-2CE2, CAV25080YE-GT3, or M95080-DRDW3TP/K. The BR25H080FVT-2CE2 and CAV25080YE-GT3 carry AEC-Q100 automotive qualification, suitable for automotive-grade applications.

For applications with reduced supply voltage requirements below 2.5V, select AT25080B-XHL-B, CAT25080YI-GT3, M95080-DFDW6TP, M95080-DRDW3TP/K, M95080-RDW6TP, or R1EX25008ATA00I#S0, all supporting 1.8V minimum supply voltage.

For maximum inventory availability, M95080-RDW6TP offers 33,400 pieces in stock. For matching the original 10 MHz clock frequency specification, BR25H080FVT-2CE2 is the direct equivalent. For higher performance at 20 MHz clock frequency, multiple options from STMicroelectronics and onsemi are available.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 20 MHz part for the original 10 MHz 25LC080D-E/ST?

A: Yes. Higher clock frequency parts operate at equal or lower speeds without functional degradation. A 20 MHz device functions correctly in a 10 MHz application. Verify that your circuit design does not impose upper frequency limits.

Q: What is the significance of MSL rating differences between parts?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture precautions. MSL 3 requires storage in controlled humidity conditions (168 hours maximum exposure). The original part has MSL 1; AT25080B-XHL-B has MSL 3. Select MSL 1 parts for applications with extended storage or high-humidity environments.

Q: Are all substitute parts pin-compatible with the 25LC080D-E/ST?

A: Yes. All listed substitutes use the 8-TSSOP package with identical 0.173" width and 4.40mm dimensions. Pin configuration and SPI interface protocol are standardized across all parts.

Q: Which substitute offers the best temperature range coverage?

A: BR25H080FVT-2CE2, CAV25080YE-GT3, and M95080-DRDW3TP/K all support -40°C to 125°C operating temperature, matching the original specification. These parts are suitable for extended temperature applications.

Q: Can I use R1EX25008ATA00I#S0 as a direct replacement?

A: R1EX25008ATA00I#S0 operates at 5 MHz clock frequency, which is lower than the original 10 MHz specification. Use this part only if your application can tolerate reduced clock speed performance.

Q: What packaging formats are available for these substitutes?

A: The original 25LC080D-E/ST is supplied in Tube packaging. Substitute parts are available in Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® formats. Verify packaging requirements for your procurement and assembly processes.
