Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT1163WI-30-G is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with identical channel count (1 channel)
• Voltage Monitoring: Single voltage threshold at 3V
• Output Stage: Open Drain or Open Collector configuration
• Reset Behavior: Active High/Active Low capability
• Reset Timeout: 130ms Minimum specification
• Operating Temperature: -40°C to 85°C range
• Package: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting: Surface Mount technology

The substitute part N84C163WD30TG meets all these criteria while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Tape & Reel packaging format of the substitute part is standard for production environments and provides improved handling and automated assembly compatibility compared to alternative packaging methods.

Both parts maintain the same 8-SOIC package geometry and surface mount mounting type, enabling direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can N84C163WD30TG be used as a direct replacement for CAT1163WI-30-G?

A: Yes. Both parts are functionally identical across all critical parameters: single-channel voltage monitoring at 3V threshold, open drain/open collector output, 130ms reset timeout, and 8-SOIC package configuration. The substitute part is electrically and mechanically compatible for direct board-level substitution.

Q: What is the primary reason for substitution?

A: The CAT1163WI-30-G is obsolete. The N84C163WD30TG provides equivalent functionality with active product status and current manufacturing availability.

Q: Are there package compatibility concerns?

A: No. Both parts use identical 8-SOIC (0.154", 3.90mm Width) packaging. PCB footprints and assembly processes require no modification.

Q: Does the substitute part meet current compliance standards?

A: Yes. The N84C163WD30TG is ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the difference in packaging format?

A: The substitute part is supplied in Tape & Reel (TR) format, which is standard for production volume orders and automated assembly processes. This format does not affect electrical or mechanical compatibility.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across -40°C to 85°C (TA), maintaining identical thermal specifications for system design purposes.
