ICL7665AESA+ Equivalent & Substitute Parts

Part Overview

The ICL7665AESA+ is a multi-voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring real-time voltage monitoring. This device monitors two independent voltage channels with adjustable or selectable thresholds and provides active-high reset output via open drain or open collector configuration. The part is currently in active production status with 2336 units available in new original inventory. Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICL7665AESA+ must maintain functional and electrical equivalence across the following critical parameters:

• Voltage Monitoring Channels: Exactly 2 independent channels required
• Threshold Configuration: Adjustable or selectable voltage thresholds
• Output Type: Open drain or open collector output stage
• Reset Polarity: Active high reset signal
• Reset Response Time: Less than 1ms minimum timeout
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Operating Temperature: -40°C to 85°C ambient temperature range
• Regulatory Compliance: ROHS3 compliant, REACH unaffected status

Parts meeting all these parameters are considered direct functional equivalents. The ICL7665AESA+ serves as both the primary reference and the confirmed substitute, as it satisfies all substitution criteria without deviation.

Parameter Comparison

Engineering Selection Recommendations

The ICL7665AESA+ maintains active production status with confirmed inventory availability of 2336 units in new original condition. This part carries ROHS3 compliance certification and REACH unaffected regulatory status, meeting current environmental and hazardous substance restrictions for industrial and commercial applications. The MSL rating of 1 (unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing and assembly operations. Selection of this part number is supported by its active product lifecycle status and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the ICL7665AESA+?

A: A valid substitute must maintain identical specifications across all critical parameters: 2-channel voltage monitoring, adjustable/selectable thresholds, open drain or open collector output, active-high reset logic with <1ms timeout, 8-SOIC package format, -40°C to 85°C operating range, and ROHS3 compliance.

Q: Is the ICL7665AESA+ available as a direct substitute for itself?

A: Yes. The ICL7665AESA+ meets all substitution criteria and is confirmed as a direct equivalent with 2336 units currently in new original inventory.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm width) package defines the physical footprint and pin configuration. Substitute parts must use this identical package to ensure PCB layout compatibility and assembly process alignment without design modifications.

Q: Does the open drain or open collector output configuration affect substitution?

A: No. Both output types are functionally equivalent for this device category and satisfy the substitution requirement. Circuit design must account for the specific output configuration during implementation.

Q: What does the MSL rating of 1 indicate?

A: MSL 1 (unlimited) means the component has no moisture sensitivity restrictions. It can be stored and handled under standard industrial conditions without special desiccant packaging or bake-out procedures prior to assembly.

Q: Are there temperature-derating considerations for applications outside the -40°C to 85°C range?

A: The ICL7665AESA+ is specified for -40°C to 85°C ambient temperature operation. Applications requiring extended temperature ranges must evaluate alternative part numbers with different thermal specifications.
