Substitute Part Grouping Explanation

Substitution eligibility for the CAT1162WI30 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single-channel voltage monitoring
• Voltage Threshold: 3V monitoring capability
• Output Stage: Open Drain or Open Collector configuration
• Reset Behavior: Active High/Active Low reset control
• Reset Timeout: 130ms minimum specification
• Operating Temperature: -40°C to 85°C range
• Package: 8-SOIC surface mount form factor
• Electrical Compliance: REACH Unaffected, EAR99 classification, HTSUS 8542.39.0001

The substitute part N84C162WD30TG meets all these criteria and is manufactured by onsemi, ensuring design and functional compatibility. The primary distinction is product status: CAT1162WI30 is obsolete, while N84C162WD30TG maintains active status with current manufacturing support.

• RoHS Compliance: N84C162WD30TG is ROHS3 compliant, meeting modern environmental and regulatory requirements
• Package Compatibility: Identical 8-SOIC surface mount package ensures direct PCB layout compatibility without redesign
• Packaging Format: N84C162WD30TG is supplied in Tape & Reel format, supporting automated assembly processes

For new designs or production transitions, N84C162WD30TG is the appropriate selection. For legacy system maintenance where CAT1162WI30 components are required, N84C162WD30TG provides full functional replacement with enhanced product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can N84C162WD30TG be used as a direct replacement for CAT1162WI30 in existing designs?

A: Yes. N84C162WD30TG is electrically and mechanically equivalent to CAT1162WI30. All critical parameters—voltage threshold (3V), reset timeout (130ms minimum), output configuration (open drain/open collector), operating temperature range (-40°C to 85°C), and package type (8-SOIC)—are identical. No circuit modifications or PCB redesign are required.

Q: What is the primary reason to substitute CAT1162WI30 with N84C162WD30TG?

A: CAT1162WI30 is classified as obsolete, which creates supply chain risk and limits long-term availability. N84C162WD30TG is an active product from the same manufacturer (onsemi) with identical specifications, ensuring reliable sourcing and manufacturing support.

Q: Are there differences in packaging between these parts?

A: Both parts use the same 8-SOIC surface mount package (0.154", 3.90mm width). The primary packaging difference is format: N84C162WD30TG is supplied in Tape & Reel (TR) format, which is standard for automated assembly. This does not affect electrical performance or PCB compatibility.

Q: Does N84C162WD30TG meet current environmental compliance standards?

A: Yes. N84C162WD30TG is ROHS3 compliant and maintains REACH Unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Are there any functional differences in reset behavior between CAT1162WI30 and N84C162WD30TG?

A: No. Both parts provide identical reset functionality: Active High/Active Low reset control with 130ms minimum timeout, single-channel voltage monitoring at 3V threshold, and open drain or open collector output configuration.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C (TA), supporting the same thermal operating envelope. No thermal derating or application modifications are necessary.
