Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICL7665EPA is determined by strict equivalence across the following critical parameters:

• Functional Type: Multi-voltage supervisor with 2-channel monitoring capability
• Output Configuration: Open drain or open collector output
• Voltage Threshold Control: Adjustable/selectable threshold settings
• Reset Characteristics: Active high reset with <1ms minimum timeout
• Operating Temperature Range: -40°C to 85°C
• Package Format: 8-DIP through-hole configuration (0.300", 7.62mm)
• Electrical Interface: Pin-compatible 8-PDIP supplier device package

The ICL7665AEPA+ meets all these criteria and qualifies as a parametric equivalent substitute. Both parts share identical functional specifications, electrical characteristics, and physical packaging, enabling direct replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The ICL7665AEPA+ is the direct substitute for the obsolete ICL7665EPA. Both components are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical and mechanical specifications. The primary distinction is product status: the ICL7665EPA is obsolete, while the ICL7665AEPA+ is active and currently in production.

For new designs and ongoing system support, the ICL7665AEPA+ is the appropriate selection. This part offers improved compliance status, with ROHS3 certification compared to the non-compliant RoHS status of the original part. Both components share identical packaging (8-DIP through-hole), electrical characteristics, and functional performance, ensuring seamless integration into existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can the ICL7665AEPA+ be used as a direct replacement for the ICL7665EPA?

A: Yes. Both parts are electrically and mechanically identical. The ICL7665AEPA+ is pin-compatible and functionally equivalent, requiring no circuit modifications for substitution.

Q: What is the primary reason for substituting the ICL7665EPA?

A: The ICL7665EPA is classified as obsolete. The ICL7665AEPA+ is the active production equivalent, ensuring long-term availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Both parts use identical 8-DIP through-hole packaging (0.300", 7.62mm). The ICL7665AEPA+ is supplied in tube packaging, while the original ICL7665EPA packaging format is not specified in the technical data.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on matching the following parameters: 2-channel multi-voltage supervisor functionality, adjustable/selectable voltage threshold, open drain or open collector output, active high reset with <1ms minimum timeout, -40°C to 85°C operating temperature range, and 8-DIP through-hole package format.

Q: Does the ICL7665AEPA+ meet current compliance requirements?

A: Yes. The ICL7665AEPA+ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original ICL7665EPA is RoHS non-compliant.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical electrical specifications, including voltage monitoring capability, threshold adjustment range, reset characteristics, and operating temperature range.
