Substitute Part Grouping Explanation

Substitution of the CAT1163WI-42-G 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: 4.25V monitoring threshold
• Output Configuration: Open Drain or Open Collector output
• Reset Behavior: Active High/Active Low capability
• Reset Timeout: 130ms minimum specification
• Operating Temperature: -40°C to 85°C range
• Package Form Factor: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Moisture Sensitivity: MSL 1 rating

The substitute part N84C163WD42TG meets all these parameters while maintaining active product status and current manufacturing availability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can N84C163WD42TG be used as a direct replacement for CAT1163WI-42-G?

A: Yes. Both parts share identical electrical specifications including voltage threshold (4.25V), output configuration (open drain/open collector), reset timeout (130ms minimum), and operating temperature range (-40°C to 85°C). The 8-SOIC package form factor is identical, enabling direct PCB substitution without layout modifications.

Q: What is the primary reason for substitution?

A: The CAT1163WI-42-G is classified as obsolete. The N84C163WD42TG maintains active product status with current manufacturing and distribution, ensuring long-term supply availability.

Q: Are there packaging differences between these parts?

A: The CAT1163WI-42-G packaging format is not specified in available data. The N84C163WD42TG is supplied in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly processes.

Q: Do compliance certifications differ?

A: The N84C163WD42TG carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. Both parts maintain REACH unaffected status.

Q: Are the pin configurations identical?

A: Yes. Both parts use the 8-SOIC package with identical pinout, enabling direct schematic and PCB substitution without design changes.
