Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25C080T-E/SN is determined by the following mandatory parameters:

• Memory Size: 8Kbit (non-negotiable)
• Memory Organization: 1K x 8 (non-negotiable)
• Memory Interface: SPI (non-negotiable)
• Package / Case: 8-SOIC form factor with 0.154" width (non-negotiable)
• Mounting Type: Surface Mount (non-negotiable)

Substitute parts may vary in clock frequency (equal to or greater than 3 MHz), supply voltage range (equal to or broader than 4.5V ~ 5.5V), operating temperature range, and write cycle time, provided the core memory specifications and physical package remain identical. Parts with different package widths (such as 0.173" width) or different package designations (such as 8-SOP versus 8-SOIC) are listed for reference but represent package variants requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection among equivalent parts should be based on the following criteria:

Direct Package Match (0.154" width, 8-SOIC): Parts 25LC080DT-E/SN, AT25080B-SSHL-T, BR25H080FJ-2CE2, CAT25080VI-GT3, M95080-DRMN3TP/K, M95080-RMN6TP, M95080-WMN6P, and M95080-WMN6TP are pin-compatible with the 25C080T-E/SN without PCB layout modification.

Package Variant (0.173" width, 8-SOIC): Parts BR25H080F-2CE2 and BR25H080F-2LBH2 feature a wider package body and require PCB footprint verification before implementation.

Automotive Grade Qualification: Parts M95080-DRMN3TP/K and BR25H080FJ-2CE2 carry AEC-Q100 qualification for automotive applications.

Temperature Range Consideration: The 25C080T-E/SN operates to 125°C. Substitute parts AT25080B-SSHL-T, CAT25080VI-GT3, M95080-RMN6TP, M95080-WMN6P, and M95080-WMN6TP are limited to 85°C maximum operating temperature and are suitable only for applications not requiring the full industrial temperature range.

Supply Voltage Range: The 25C080T-E/SN requires 4.5V ~ 5.5V operation. Substitute parts with broader voltage ranges (1.8V ~ 5.5V or 2.5V ~ 5.5V) provide additional design flexibility for lower-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different clock frequency? A: Yes. The 25C080T-E/SN operates at 3 MHz. Substitute parts with equal or higher clock frequencies (10 MHz, 20 MHz) are compatible and provide performance headroom. Lower clock frequency parts are not suitable.

Q: What is the significance of the package width difference (0.154" versus 0.173")? A: Package width affects PCB footprint dimensions. Parts with 0.154" width (such as 25LC080DT-E/SN, M95080-WMN6TP) are direct replacements. Parts with 0.173" width (such as BR25H080F-2CE2) require PCB layout verification to confirm pad spacing compatibility.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the environmental compliance of the 25C080T-E/SN.

Q: Which substitute part is recommended for automotive applications? A: Parts M95080-DRMN3TP/K and BR25H080FJ-2CE2 carry AEC-Q100 qualification for automotive-grade reliability. These parts are suitable for automotive temperature and reliability requirements.

Q: Can I use a substitute part with a lower supply voltage range? A: No. The 25C080T-E/SN requires 4.5V ~ 5.5V operation. Substitute parts must support this voltage range. Parts with narrower ranges (such as 1.8V ~ 5.5V minimum) are acceptable only if your application supplies voltage within the 4.5V ~ 5.5V window.

Q: What is the difference between the Microchip 25C080T-E/SN and 25LC080DT-E/SN? A: Both are 8Kbit SPI EEPROM devices in 8-SOIC packaging. The primary difference is clock frequency: 25C080T-E/SN operates at 3 MHz, while 25LC080DT-E/SN operates at 10 MHz. The 25LC080DT-E/SN also supports a broader supply voltage range (2.5V ~ 5.5V).

Q: Are write cycle times interchangeable? A: Write cycle times of 4ms or 5ms are functionally equivalent for most applications. The 25C080T-E/SN specifies 5ms. Substitute parts with 4ms write cycle times provide faster write performance without compatibility issues.
