Substitute Part Grouping Explanation

Substitution eligibility for the SST25VF064C-80-4I-SCE-T is determined by the following critical parameters:

• Memory Size: 64Mbit (8M x 8 organization)
• Package Type: 16-SOIC form factor with identical physical dimensions
• Voltage Supply Range: 2.7V ~ 3.6V compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Memory Interface: SPI protocol support (Dual I/O or higher capability)
• Compliance: ROHS3 and REACH status alignment

The SST26VF064BT-104I/SO qualifies as a substitute based on matching memory capacity, identical package specifications, overlapping voltage and temperature ranges, and enhanced SPI interface capability (Quad I/O). The substitute maintains backward compatibility while offering improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SST26VF064BT-104I/SO is a direct substitute for the obsolete SST25VF064C-80-4I-SCE-T. Both parts maintain identical memory capacity, package form factor, voltage specifications, and temperature operating range. The substitute carries Active product status, ensuring long-term availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH requirements, meeting current regulatory standards for electronic components.

The SST26VF064BT-104I/SO offers enhanced performance through increased clock frequency (104 MHz versus 80 MHz) and reduced write cycle time (1.5ms versus 2.5ms). The Quad I/O interface provides expanded data throughput capability while maintaining full backward compatibility with SPI Dual I/O protocol implementations.

Frequently Asked Questions (FAQ)

Q: Can the SST26VF064BT-104I/SO directly replace the SST25VF064C-80-4I-SCE-T in existing designs?

A: Yes. Both parts share identical memory capacity (64Mbit), package specifications (16-SOIC), voltage supply range (2.7V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The substitute's Quad I/O interface is backward compatible with Dual I/O protocol operation.

Q: What are the key differences between these two parts?

A: The primary differences are clock frequency (104 MHz versus 80 MHz), write cycle time (1.5ms versus 2.5ms), memory interface capability (Quad I/O versus Dual I/O), and product status (Active versus Obsolete). The substitute provides improved performance metrics.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the SST25VF064C-80-4I-SCE-T and SST26VF064BT-104I/SO are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory standards.

Q: Does the package form factor remain identical?

A: Yes. Both parts use the 16-SOIC package with identical physical dimensions (0.295" width, 7.50mm). No PCB layout modifications are required for substitution.

Q: What is the significance of the Active product status for the substitute?

A: Active product status indicates the SST26VF064BT-104I/SO is in current production with guaranteed long-term availability, addressing the supply discontinuation risk associated with the obsolete SST25VF064C-80-4I-SCE-T.
