CAT1163WI28 Equivalent & Substitute Parts

Part Overview

The CAT1163WI28 is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset/power-on reset controller with open drain or open collector output. This component monitors a single voltage channel with a threshold of 2.85V and provides active high/active low reset functionality with a 130ms minimum timeout.

The CAT1163WI28 is classified as obsolete. Locating active equivalent parts is necessary to ensure continued supply chain availability and support for new designs or production runs requiring supervisor functionality in the 8-SOIC package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CAT1163WI28 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor
• Voltage Monitoring Channels: 1 channel
• Voltage Threshold: 2.85V
• Output Configuration: Open Drain or Open Collector
• Reset Logic: Active High/Active Low capability
• Reset Timeout: 130ms Minimum
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package Format: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The substitute part N84C163WD28TG meets all these criteria and maintains electrical and mechanical compatibility with the original CAT1163WI28 design.

Parameter Comparison

Engineering Selection Recommendations

The N84C163WD28TG is the direct functional equivalent to the CAT1163WI28. The primary distinction is product status: the CAT1163WI28 is obsolete, while the N84C163WD28TG is active and currently in production.

From a compliance perspective, the N84C163WD28TG carries RoHS3 compliance and EAR99 ECCN classification, providing regulatory alignment for current manufacturing standards. Both parts share identical electrical specifications and the same 8-SOIC package footprint, ensuring direct PCB compatibility without layout modifications.

The N84C163WD28TG is supplied in Tape & Reel (TR) packaging, which is standard for production environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the N84C163WD28TG be used as a direct replacement for the CAT1163WI28?

A: Yes. Both parts are functionally identical across all critical parameters: single-channel voltage monitoring at 2.85V threshold, open drain/open collector output, active high/active low reset logic, 130ms minimum reset timeout, and identical 8-SOIC package dimensions. No circuit modifications or PCB redesign is required.

Q: Are there any package differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) package. The CAT1163WI28 packaging format is not specified in the data provided. The N84C163WD28TG is supplied in Tape & Reel (TR) format, which is standard for production quantities and automated assembly.

Q: What is the significance of the product status difference?

A: The CAT1163WI28 is obsolete and no longer manufactured. The N84C163WD28TG is an active product in current production, ensuring long-term supply chain availability and support.

Q: Are there compliance or certification differences?

A: The N84C163WD28TG is RoHS3 compliant and carries EAR99 ECCN classification. Both parts have MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. The N84C163WD28TG aligns with current regulatory requirements for electronic components.

Q: What is the operating temperature range for both parts?
