25LC080DT-H/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC080DT-H/SN is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 5 MHz with a supply voltage range of 2.5V to 5.5V and is housed in an 8-SOIC package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for cost optimization, or when design specifications allow for compatible alternatives with enhanced performance characteristics such as higher clock frequencies or extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080DT-H/SN is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory Size: 8Kbit (mandatory)
• Memory Organization: 1K x 8 (mandatory)
• Memory Interface: SPI (mandatory)
• Package Type: 8-SOIC with 0.154" width and 3.90mm width (mandatory for direct pin compatibility)
• Voltage Supply Range: Must encompass or be compatible with 2.5V ~ 5.5V
• RoHS Compliance: ROHS3 Compliant (mandatory)

Performance Enhancement Parameters (allowable variations):

• Clock Frequency: May exceed 5 MHz (higher frequencies are backward compatible)
• Write Cycle Time: May be shorter than 6ms (faster operation is acceptable)
• Operating Temperature: May extend beyond -40°C ~ 150°C range

Substitute parts are grouped into two categories based on package geometry:

Group 1 - Direct Package Match (8-SOIC 0.154" / 3.90mm):

• M95080-RMN6TP
• M95080-WMN6TP
• CAT25080VI-GT3
• BR25H080FJ-2CE2

Group 2 - Compatible Package Variant (8-SOIC 0.173" / 4.40mm):

• BR25H080F-2CE2
• BR25H080F-2LBH2

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Package Geometry):

The M95080-WMN6TP and M95080-RMN6TP from STMicroelectronics provide the highest performance enhancement with 20 MHz clock frequency and 5ms write cycle time. Both parts maintain ROHS3 compliance and are suitable for applications requiring higher data throughput. The M95080-WMN6TP maintains the original 2.5V minimum supply voltage, while the M95080-RMN6TP extends the lower voltage limit to 1.8V for low-power applications.

The CAT25080VI-GT3 from onsemi offers 1.8V minimum supply voltage compatibility and 5ms write cycle time while maintaining the identical 8-SOIC package footprint. This part is suitable for battery-powered or low-voltage system designs.

The BR25H080FJ-2CE2 from Rohm Semiconductor provides 10 MHz clock frequency with AEC-Q100 automotive qualification and maintains the original package dimensions. This part is appropriate for automotive-grade applications requiring extended temperature operation to -40°C.

Compatible Substitutes (Package Variant):

The BR25H080F-2CE2 and BR25H080F-2LBH2 from Rohm Semiconductor feature a slightly wider 8-SOIC package (0.173" vs. 0.154") but maintain full electrical compatibility. These parts offer 10 MHz operation and 4ms write cycle time. PCB layout verification is required to confirm package footprint compatibility before selection.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, consistent with the original part specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher clock frequency than the original 25LC080DT-H/SN?

A: Yes. Higher clock frequencies are backward compatible. Parts operating at 10 MHz or 20 MHz can be used in applications designed for 5 MHz operation. The system will operate at the lower speed determined by the host controller.

Q: What is the difference between the 8-SOIC packages listed (0.154" vs. 0.173" width)?

A: The package width difference affects PCB footprint and land pattern design. The 0.154" width (3.90mm) matches the original 25LC080DT-H/SN exactly. The 0.173" width (4.40mm) variants (BR25H080F-2CE2 and BR25H080F-2LBH2) require PCB layout verification to confirm compatibility with existing designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with the original part specification.

Q: Which substitute part offers the widest operating temperature range?

A: The original 25LC080DT-H/SN operates from -40°C to 150°C. All substitute parts operate within -40°C to 125°C or -40°C to 85°C ranges, which are narrower than the original specification.

Q: Can I use the BR25H080F series parts as direct replacements?

A: The BR25H080FJ-2CE2 is a direct package replacement. The BR25H080F-2CE2 and BR25H080F-2LBH2 require PCB layout verification due to the wider 8-SOIC package variant (0.173" vs. 0.154").

Q: What is the minimum supply voltage for each substitute part?

A: M95080-WMN6TP: 2.5V; M95080-RMN6TP: 1.8V; CAT25080VI-GT3: 1.8V; BR25H080 series: 2.5V. Applications requiring operation below 2.5V should select M95080-RMN6TP or CAT25080VI-GT3.

Q: Do any substitute parts have automotive qualification?

A: Yes. The BR25H080F-2CE2, BR25H080F-2LBH2, and BR25H080FJ-2CE2 carry AEC-Q100 automotive qualification.
