Engineering Selection Recommendations

The ICL7665AESA+ is the direct substitute for the obsolete ICL7665AESA. Both devices share identical functional specifications, electrical characteristics, and package geometry, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The ICL7665AESA+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the ICL7665AESA+ meets ROHS3 compliance requirements, whereas the original ICL7665AESA is RoHS non-compliant. Both devices maintain REACH unaffected status and identical moisture sensitivity classification.

For new designs or production continuity, the ICL7665AESA+ is the appropriate selection. Existing designs utilizing the ICL7665AESA can transition to the ICL7665AESA+ without circuit modification or re-qualification, provided compliance requirements align with system specifications.

Frequently Asked Questions (FAQ)

Q: Is the ICL7665AESA+ a direct pin-for-pin replacement for the ICL7665AESA?

A: Yes. The ICL7665AESA+ maintains identical pin configuration, package dimensions (8-SOIC, 0.154" width), and electrical interface specifications. No circuit modification is required for substitution.

Q: What is the primary difference between the ICL7665AESA and ICL7665AESA+?

A: The ICL7665AESA+ is an active product with ROHS3 compliance, whereas the ICL7665AESA is obsolete and RoHS non-compliant. Functional and electrical specifications are identical.

Q: Can the ICL7665AESA+ be used in applications originally designed for the ICL7665AESA?

A: Yes. The ICL7665AESA+ provides equivalent functionality across all monitored parameters: 2-channel voltage supervision, adjustable/selectable thresholds, active high reset with <1ms timeout, open drain or open collector output, and -40°C to 85°C operating temperature range.

Q: Are there packaging differences between these parts?

A: Both devices use 8-SOIC surface mount packaging with identical dimensions. The ICL7665AESA+ is supplied in tube packaging, while the original ICL7665AESA packaging specification was not provided.

Q: What compliance certifications apply to the ICL7665AESA+?

A: The ICL7665AESA+ is ROHS3 compliant and REACH unaffected. Moisture sensitivity level is classified as 1 (unlimited). Both devices carry EAR99 ECCN classification and 8542.39.0001 HTSUS code.
