Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC1024T-E/MF is determined by the following critical parameters:

• Memory capacity: 1Mbit (128K x 8 organization)
• Interface protocol: SPI
• Operating frequency: 20 MHz
• Supply voltage compatibility: 2.5V ~ 5.5V
• Temperature range: -40°C ~ 125°C
• Physical package: 8-VDFN with exposed pad
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part 25LC1024-E/MF meets all electrical and mechanical specifications required for direct substitution. The primary difference between the main part and substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Tube packaging. Both parts share identical electrical characteristics, memory organization, interface specifications, and thermal operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 25LC1024T-E/MF and 25LC1024-E/MF are actively produced by Microchip Technology and maintain identical electrical and functional specifications. Selection between these parts should be based on procurement and assembly requirements:

The 25LC1024T-E/MF in Tape & Reel packaging is suitable for high-volume automated assembly operations where reel-fed component handling is standard.

The 25LC1024-E/MF in Tube packaging is suitable for lower-volume applications, manual assembly processes, or situations where reel packaging is not required.

Both parts carry ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical electrical specifications ensure functional interchangeability in circuit designs without modification to PCB layouts or firmware.

Frequently Asked Questions (FAQ)

Q: Can 25LC1024-E/MF be used as a direct replacement for 25LC1024T-E/MF?

A: Yes. Both parts are manufactured by Microchip Technology with identical electrical specifications, memory capacity, SPI interface, operating frequency, voltage range, and temperature rating. The only difference is packaging format (Tube versus Tape & Reel). No circuit modifications are required.

Q: What is the significance of the packaging difference between these parts?

A: Packaging format affects procurement and assembly logistics. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume production. Tube packaging is used for manual assembly, lower-volume orders, or component distribution through standard packaging channels. Electrical performance is identical.

Q: Are both parts RoHS compliant?

A: Yes. Both 25LC1024T-E/MF and 25LC1024-E/MF are ROHS3 compliant and REACH Unaffected, meeting environmental and regulatory requirements for industrial applications.

Q: What are the critical parameters for substitution eligibility?

A: Substitution is valid when the following parameters match: 1Mbit memory capacity, 128K x 8 organization, SPI interface, 20 MHz clock frequency, 2.5V to 5.5V supply voltage, -40°C to 125°C operating temperature, and 8-VDFN surface mount package. All these parameters are identical between the main part and substitute.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and functional specifications are identical, allowing direct substitution in existing PCB designs and firmware implementations without modification.
