Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT1163WI30 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor
• Voltage Monitoring: Single channel at 3V threshold
• Output Configuration: Open Drain or Open Collector
• Reset Polarity: Active High/Active Low capability
• Reset Timeout: 130ms Minimum
• Operating Temperature: -40°C ~ 85°C (TA)
• Package: 8-SOIC form factor with identical physical dimensions
• Mounting: Surface Mount technology

The substitute part N84C163WD30TG meets all these parameters identically, with the primary distinction being product status and packaging format.
