Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF22V10C-10SC is determined by strict equivalence across the following critical parameters:

• Series designation (22V10)
• Macrocell count (10)
• Propagation delay (10 ns)
• Supply voltage (5V)
• Package type (24-SOIC)
• Mounting configuration (Surface Mount)
• Programmable technology (EE PLD)

The ATF22V10C-10SU meets all these criteria and is therefore classified as a direct functional equivalent. Both parts share identical electrical specifications, pinout configuration, and programming characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATF22V10C-10SU is the direct substitute for the obsolete ATF22V10C-10SC. Both components are manufactured by Microchip Technology and provide identical electrical and functional performance. The primary distinction is product lifecycle status: the ATF22V10C-10SU maintains active production status, ensuring continued availability and supply chain reliability.

From a compliance perspective, the ATF22V10C-10SU offers ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations. Both parts maintain equivalent REACH and ECCN classifications.

Packaging differs only in supplier delivery format: the substitute is supplied in tube packaging, which does not affect component functionality or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the ATF22V10C-10SC and ATF22V10C-10SU pin-compatible?

A: Yes. Both components utilize the 24-SOIC package with identical pinout configuration. Direct PCB substitution is possible without layout modification.

Q: What is the difference between the two part numbers?

A: The suffix designates packaging format. The "-10SC" indicates standard packaging, while "-10SU" specifies tube packaging. Electrical specifications and performance are identical.

Q: Can the ATF22V10C-10SU be used in designs originally specified for the ATF22V10C-10SC?

A: Yes. The substitute part meets all electrical, timing, and functional requirements of the original specification. Existing firmware and programming data are directly compatible.

Q: Why is the original part listed as obsolete?

A: Product lifecycle management by Microchip Technology has transitioned this component to obsolete status. The ATF22V10C-10SU remains in active production and is the recommended alternative for new and ongoing designs.

Q: Are there compliance considerations when substituting these parts?

A: The ATF22V10C-10SU provides ROHS3 compliance, which may be required for certain applications or markets. The original part does not meet this standard. Verify compliance requirements for your specific application.

Q: What is the moisture sensitivity level for both parts?

A: Both components are rated MSL 2 with a 1-year floor life. Standard moisture control procedures during storage and handling apply to both parts.
