25LC080DT-E/SN Equivalent & Substitute Parts

Part Overview

The 25LC080DT-E/SN is an 8Kbit EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates via Serial Peripheral Interface (SPI) at 10 MHz clock frequency and is housed in an 8-SOIC surface mount package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers or packaging configurations. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required for supply chain optimization.

Engineering Selection Recommendations

Direct Packaging Equivalents (Identical Electrical Specifications):

The 25LC080D-E/SN and 25LC080CT-E/SN are direct electrical equivalents to the 25LC080DT-E/SN, differing only in packaging configuration (Tube and Tape & Reel respectively versus Cut Tape & Digi-Reel). These parts maintain identical clock frequency, supply voltage range, operating temperature, and write cycle time specifications. Selection between these variants depends on assembly process requirements and tape handling capabilities.

Automotive-Grade Equivalents (10 MHz, AEC-Q100 Qualified):

The BR25H080F-2CE2 and BR25H080FJ-2CE2 from Rohm Semiconductor provide 10 MHz operation with identical supply voltage and operating temperature ranges. Both parts carry AEC-Q100 automotive qualification and feature 4ms write cycle time. The BR25H080FJ-2CE2 maintains the exact 8-SOIC package width (0.154", 3.90mm) as the primary part, while BR25H080F-2CE2 uses a slightly wider 8-SOP package (0.173", 4.40mm). Both are ROHS3 compliant with unlimited moisture sensitivity rating.

Higher-Performance Variants (20 MHz Operation):

The AT25080B-SSHL-B, M95080-WMN6TP, CAV25080VE-GT3, M95080-DRMN3TP/K, and M95080-RMN6TP operate at 20 MHz clock frequency, providing doubled performance headroom while maintaining full backward compatibility with 10 MHz system designs. These parts are suitable for applications requiring increased data throughput. Operating temperature ranges vary: CAV25080VE-GT3 and M95080-DRMN3TP/K support the full -40°C ~ 125°C range, while AT25080B-SSHL-B and M95080-RMN6TP are limited to -40°C ~ 85°C. Supply voltage ranges also vary; M95080-DRMN3TP/K, M95080-RMN6TP, and AT25080B-SSHL-B support 1.8V minimum operation.

onsemi CAT25080VI-GT3 Consideration:

The CAT25080VI-GT3 provides 8Kbit SPI EEPROM functionality with 1.8V ~ 5.5V supply range and -40°C ~ 85°C operating temperature. Clock frequency specification is not provided in available documentation. This part is suitable for low-voltage applications but operating temperature range is restricted compared to the primary part.

All substitute parts listed maintain ROHS3 compliance and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can the 25LC080CT-E/SN be used as a direct replacement for the 25LC080DT-E/SN?

A: Yes. Both parts are manufactured by Microchip Technology with identical electrical specifications: 8Kbit capacity, 10 MHz SPI operation, 2.5V ~ 5.5V supply range, -40°C ~ 125°C operating temperature, and 5ms write cycle time. The difference is packaging format: 25LC080CT-E/SN uses Tape & Reel while 25LC080DT-E/SN uses Cut Tape & Digi-Reel. Selection depends on assembly equipment compatibility.

Q: Are 20 MHz parts backward compatible with 10 MHz designs?

A: Yes. Parts operating at 20 MHz clock frequency (AT25080B-SSHL-B, M95080-WMN6TP, CAV25080VE-GT3, M95080-DRMN3TP/K, M95080-RMN6TP) are fully backward compatible with systems designed for 10 MHz operation. The higher clock frequency provides additional performance margin without requiring design changes.

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

A: Both are Rohm Semiconductor automotive-grade parts with identical electrical specifications. The primary difference is package width: BR25H080F-2CE2 uses 8-SOP package (0.173", 4.40mm width) while BR25H080FJ-2CE2 uses 8-SOP-J package (0.154", 3.90mm width). The BR25H080FJ-2CE2 matches the exact package width of the 25LC080DT-E/SN.

Q: Which substitute parts support the full -40°C ~ 125°C operating temperature range?

A: The 25LC080D-E/SN, 25LC080CT-E/SN, BR25H080F-2CE2, BR25H080FJ-2CE2, CAV25080VE-GT3, and M95080-DRMN3TP/K all support the complete -40°C ~ 125°C temperature range. Parts with restricted temperature ranges (-40°C ~ 85°C) are AT25080B-SSHL-B, M95080-WMN6TP, M95080-RMN6TP, and CAT25080VI-GT3.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and carry REACH Unaffected status, matching the compliance profile of the 25LC080DT-E/SN.

Q: Which parts have automotive qualification?

A: The BR25H080F-2CE2, BR25H080FJ-2CE2, CAV25080VE-GT3, and M95080-DRMN3TP/K carry AEC-Q100 automotive qualification. These parts are suitable for automotive and industrial applications requiring formal qualification documentation.

Q: What is the significance of moisture sensitivity level (MSL) ratings?

A: The 25LC080DT-E/SN has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Substitute parts with MSL 1 (25LC080CT-E/SN, M95080-WMN6TP, BR25H080F-2CE2, BR25H080FJ-2CE2, CAT25080VI-GT3, CAV25080VE-GT3, M95080-DRMN3TP/K, M95080-RMN6TP) offer identical handling flexibility. The 25LC080D-E/SN has MSL 3 (168 Hours), requiring controlled storage conditions.

Q: Can I use CAT25080VI-GT3 in place of 25LC080DT-E/SN?

A: The CAT25080VI-GT3 provides 8Kbit SPI EEPROM functionality with compatible package and interface. However, operating temperature range is limited to -40°C ~ 85°C compared to the primary part's -40°C ~ 125°C. Clock frequency is not specified in available documentation. Selection depends on application temperature requirements.

Q: What are the supply voltage compatibility considerations?

A: The 25LC080DT-E/SN operates from 2.5V ~ 5.5V. Most substitute parts maintain this range. However, AT25080B-SSHL-B, M95080-DRMN3TP/K, M95080-RMN6TP, CAT25080VI-GT3, and CAV25080VE-GT3 support lower minimum voltages (1.8V), making them suitable for low-voltage applications.
