Parameter Comparison

Engineering Selection Recommendations

The ATF22V10CQZ-20JU is the direct functional equivalent for the obsolete ATF22V10BQL-20JC. Selection between these parts should be based on the following factors:

Product Status: The ATF22V10CQZ-20JU maintains Active product status, ensuring continued availability and manufacturer support. The ATF22V10BQL-20JC is Obsolete, limiting future procurement options.

Compliance Requirements: The ATF22V10CQZ-20JU is ROHS3 compliant, meeting current environmental and regulatory standards. The ATF22V10BQL-20JC is RoHS non-compliant, which may conflict with modern supply chain and end-product requirements.

Moisture Sensitivity: The ATF22V10CQZ-20JU carries MSL 3 (168 Hours), while the ATF22V10BQL-20JC carries MSL 2 (1 Year). Both specifications are within acceptable handling parameters for standard manufacturing environments.

Programmable Verification: The ATF22V10CQZ-20JU is DiGi-Electronics Programmable Verified, confirming programming compatibility and functionality validation.

All electrical and mechanical parameters remain identical, ensuring direct pin-for-pin and functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the ATF22V10CQZ-20JU be used as a direct replacement for the ATF22V10BQL-20JC?

A: Yes. Both devices share identical electrical specifications (10 macrocells, 20 ns speed, 5V input), programmable type (EE PLD), and package configuration (28-PLCC J-Lead surface mount). Pin-for-pin and functional compatibility is maintained.

Q: What is the primary reason to transition from ATF22V10BQL-20JC to ATF22V10CQZ-20JU?

A: The ATF22V10BQL-20JC is Obsolete, while the ATF22V10CQZ-20JU is Active. This ensures long-term availability, manufacturer support, and compliance with current regulatory standards (ROHS3).

Q: Are there any package or mounting differences between these parts?
