Key Parameters

Substitute Part Grouping Explanation

Substitution of the 25LC512T-I/MF is determined by strict equivalence across the following critical parameters:

• Memory capacity: 512Kbit (64K x 8 organization)
• Interface protocol: SPI serial communication
• Operating frequency: 20 MHz maximum clock speed
• Supply voltage compatibility: 2.5V to 5.5V range
• Package form factor: 8-pin VDFN with exposed pad
• Temperature rating: -40°C to 85°C operational range
• Compliance certifications: ROHS3 compliance required

The substitute part 25LC512-I/MF meets all these criteria and differs only in packaging configuration (Tube versus standard packaging). Both parts share identical electrical characteristics, memory specifications, and thermal performance, making them functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the 25LC512T-I/MF and 25LC512-I/MF are actively manufactured by Microchip Technology and maintain ROHS3 compliance. Selection between these parts should be based on procurement requirements and packaging specifications. The 25LC512T-I/MF is supplied in standard packaging, while the 25LC512-I/MF is supplied in Tube packaging. From an electrical and functional standpoint, both parts are equivalent and will perform identically in circuit applications. Inventory availability and supply chain logistics may influence part selection, as current stock levels differ between the two variants.
