ICL7665BCSA Equivalent & Substitute Parts

Part Overview

The ICL7665BCSA is a multi-voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring monitoring of two voltage channels. This device features open drain or open collector output with active high reset functionality and operates across the industrial temperature range of 0°C to 70°C. The ICL7665BCSA is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICL7665BCSA are 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
• Reset Characteristics: Active high reset with <1ms minimum timeout
• Voltage Threshold Control: Adjustable/selectable threshold settings
• Package Specification: 8-SOIC surface mount package (0.154", 3.90mm width)
• Operating Temperature Range: 0°C to 70°C
• Moisture Sensitivity: MSL 1 (Unlimited)

The identified substitute parts ICL7665ACSA+ and ICL7665CSA+ maintain identical electrical and mechanical specifications to the main part number while differing in product status and compliance certifications. Both substitutes are derived from the same ICL7665 base product family and are packaged in tube format.

Parameter Comparison

Engineering Selection Recommendations

Both ICL7665ACSA+ and ICL7665CSA+ are functionally equivalent to the ICL7665BCSA across all electrical and mechanical parameters. The primary distinctions are product lifecycle status and regulatory compliance:

ICL7665ACSA+ and ICL7665CSA+ are both active products with ROHS3 compliance certification, whereas the ICL7665BCSA is obsolete and RoHS non-compliant. For new designs or system refreshes, either active substitute part is appropriate. The choice between ICL7665ACSA+ and ICL7665CSA+ should be based on availability and supply chain considerations, as both maintain identical functional specifications and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ICL7665ACSA+ or ICL7665CSA+ be used as direct replacements for ICL7665BCSA in existing designs?

A: Yes. Both substitute parts maintain identical electrical characteristics, output configuration, reset timing, and package specifications. Direct substitution is supported at the circuit level.

Q: What is the significance of the product status difference between the main part and substitutes?

A: The ICL7665BCSA is classified as obsolete, indicating it is no longer manufactured or supported by the supplier. The substitute parts ICL7665ACSA+ and ICL7665CSA+ are active products with ongoing manufacturing and supply availability.

Q: Are there compliance differences between the three part numbers?

A: The ICL7665BCSA is RoHS non-compliant, while both ICL7665ACSA+ and ICL7665CSA+ are ROHS3 compliant. All three parts maintain identical REACH and ECCN classifications.

Q: Does packaging format affect substitution compatibility?

A: The ICL7665BCSA and substitute parts all use the 8-SOIC surface mount package with identical dimensions (0.154", 3.90mm width). Packaging format differences (tube versus other formats) do not affect electrical or mechanical compatibility.

Q: What inventory considerations should be evaluated when selecting between substitute parts?

A: ICL7665ACSA+ has 2525 units in stock, while ICL7665CSA+ has 1367 units available. Both maintain sufficient inventory for production requirements.
