Engineering Selection Recommendations

Both ICL7665SCPAZ and ICL7665SACPAZ are direct functional equivalents to the obsolete ICL7665SCPA. Selection between these active alternatives should be based on the following factors:

ICL7665SCPAZ is the direct manufacturer equivalent, maintaining the same part number structure with the addition of the "Z" suffix indicating active product status and ROHS3 compliance certification.

ICL7665SACPAZ is a parametric equivalent offering identical electrical and mechanical specifications with ROHS3 compliance certification. The "A" designation in the part number indicates a variant within the ICL7665S base product family.

Both substitute parts are ROHS3 compliant, addressing regulatory requirements that may not have been applicable to the original obsolete part. Both maintain identical operating temperature ranges, package configurations, and functional specifications required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can ICL7665SCPAZ and ICL7665SACPAZ be used interchangeably with ICL7665SCPA?

A: Yes. Both parts maintain identical electrical specifications across all monitored parameters: dual-channel voltage monitoring, adjustable/selectable thresholds, open drain or open collector output, active high reset function, and 8-DIP through-hole packaging. Functional compatibility is confirmed.

Q: What is the difference between ICL7665SCPAZ and ICL7665SACPAZ?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the part number designation: ICL7665SCPAZ is the direct successor to the obsolete ICL7665SCPA, while ICL7665SACPAZ represents a variant within the ICL7665S product family. Both are active products with ROHS3 compliance.

Q: Are there any compliance differences between the original part and the substitutes?

A: The original ICL7665SCPA is RoHS non-compliant. Both substitute parts (ICL7665SCPAZ and ICL7665SACPAZ) are ROHS3 compliant. Both maintain REACH Unaffected status and identical ECCN and HTSUS classifications.

Q: Is the 8-DIP through-hole package identical across all three parts?

A: Yes. All three parts use the same 8-DIP (0.300", 7.62mm) through-hole package with 8-PDIP supplier device package designation. Direct PCB footprint compatibility is confirmed.

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

A: All three parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
