ICL7665CSA Equivalent & Substitute Parts

Part Overview

The ICL7665CSA is a multi-voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring dual-channel voltage monitoring. This 8-SOIC surface mount device features adjustable/selectable voltage thresholds, open drain or open collector output configuration, and active high reset functionality with sub-millisecond reset timeout.

The ICL7665CSA is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICL7665CSA is determined by strict equivalence across the following critical parameters:

• Dual-channel voltage monitoring capability
• Adjustable/selectable voltage threshold configuration
• Open drain or open collector output structure
• Active high reset with sub-millisecond timeout performance
• 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Operating temperature range of 0°C ~ 70°C
• Moisture sensitivity level MSL 1 (Unlimited)

The substitute parts ICL7665CSA+ and ICL7665ACSA+ meet all electrical and mechanical parameter requirements for direct substitution. Both parts maintain identical functional specifications, package geometry, and thermal operating characteristics as the original ICL7665CSA.

Parameter Comparison

Engineering Selection Recommendations

Both ICL7665CSA+ and ICL7665ACSA+ are suitable substitutes for the obsolete ICL7665CSA based on complete electrical and mechanical parameter equivalence. The primary distinction between substitute options relates to product status and regulatory compliance:

ICL7665CSA+ is classified as active product status with ROHS3 compliance certification, providing current manufacturing availability and regulatory alignment with modern environmental standards.

ICL7665ACSA+ is classified as active product status with ROHS3 compliance certification and represents the highest inventory availability (2525 pcs) among all substitute options, supporting extended production runs and supply chain continuity.

Selection between ICL7665CSA+ and ICL7665ACSA+ should be based on inventory requirements, lead time considerations, and packaging specifications (both supplied in tube packaging). The original ICL7665CSA, while available in inventory (1787 pcs), carries obsolete product status and RoHS non-compliance designation, making it unsuitable for new design implementations or applications subject to environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ICL7665CSA+ and ICL7665ACSA+ be used interchangeably with ICL7665CSA?

A: Yes. Both substitute parts maintain identical electrical specifications across all critical parameters: dual-channel voltage monitoring, adjustable/selectable thresholds, open drain/open collector output, active high reset with sub-millisecond timeout, and 8-SOIC package geometry. Pin-for-pin compatibility is assured.

Q: What is the difference between ICL7665CSA+ and ICL7665ACSA+?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary differences are product designation and inventory availability. ICL7665ACSA+ offers higher stock levels (2525 pcs vs. 1367 pcs), supporting larger production volumes.

Q: Why is the original ICL7665CSA classified as obsolete?

A: Obsolete product status indicates the part is no longer in active production by the manufacturer. ICL7665CSA+ and ICL7665ACSA+ are active production alternatives that provide equivalent functionality with current manufacturing support.

Q: Are there any compliance differences between the substitute parts and the original?

A: Yes. The original ICL7665CSA is RoHS non-compliant, while both substitute parts (ICL7665CSA+ and ICL7665ACSA+) are ROHS3 compliant. All three parts maintain REACH Unaffected status. For applications subject to environmental regulations, the compliant substitutes are required.

Q: What packaging options are available for substitute parts?

A: Both ICL7665CSA+ and ICL7665ACSA+ are supplied in tube packaging. The 8-SOIC package dimensions (0.154", 3.90mm Width) are identical across all variants, ensuring compatibility with existing PCB layouts and assembly processes.

Q: Can I mix ICL7665CSA+, ICL7665ACSA+, and ICL7665CSA in the same production batch?

A: While all three parts are electrically equivalent, mixing obsolete and active production parts is not recommended for supply chain consistency. Use either ICL7665CSA+ or ICL7665ACSA+ for new production to ensure uniform compliance status and manufacturing support.
