CAT1162WI28 Equivalent & Substitute Parts

Part Overview

The CAT1162WI28 is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset or power-on reset controller. This device monitors a single voltage channel and provides open drain or open collector output for system reset control. The CAT1162WI28 is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT1162WI28 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single voltage channel monitoring
• Voltage Threshold: 2.85V monitoring threshold
• Output Configuration: Open Drain or Open Collector output
• Reset Logic: Active High/Active Low capability
• Reset Timeout: 130ms minimum delay
• Operating Temperature: -40°C to 85°C range
• Package Format: 8-SOIC surface mount package with identical physical dimensions
• Electrical Compliance: REACH Unaffected, EAR99 classification

The N84C162WD28TG meets all these criteria and serves as a direct functional equivalent. The primary distinction is product status: the CAT1162WI28 is obsolete, while the N84C162WD28TG is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The N84C162WD28TG is the direct equivalent for the obsolete CAT1162WI28. Selection of this substitute is supported by:

• Complete Electrical Equivalence: All monitored voltages, thresholds, output configurations, and timing parameters are identical
• Identical Package: 8-SOIC surface mount package with matching physical dimensions ensures PCB compatibility without layout modification
• Active Product Status: The N84C162WD28TG is currently in active production with confirmed inventory availability (846 Pcs), eliminating supply chain risk associated with obsolete components
• Regulatory Compliance: Both REACH Unaffected and EAR99 classification maintained; the substitute adds ROHS3 compliance certification
• Temperature Range Compatibility: Operating range of -40°C to 85°C covers standard industrial and commercial applications

For new designs or system refreshes, the N84C162WD28TG should be specified. For existing systems using the CAT1162WI28, direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can the N84C162WD28TG replace the CAT1162WI28 in existing designs?

A: Yes. The N84C162WD28TG is electrically and mechanically equivalent. Both devices feature identical voltage thresholds (2.85V), output configurations (open drain/open collector), reset timing (130ms minimum), and 8-SOIC packaging. No circuit modifications are required.

Q: What is the difference between the CAT1162WI28 and N84C162WD28TG?

A: The primary difference is product status and packaging format. The CAT1162WI28 is obsolete and supplied in bulk packaging. The N84C162WD28TG is an active product supplied in Tape & Reel format and includes ROHS3 compliance certification. All electrical and functional parameters are identical.

Q: Are there any pin compatibility concerns?

A: No. Both parts use the 8-SOIC package with identical pin assignments and electrical characteristics. Direct PCB substitution is possible without layout changes.

Q: Does the N84C162WD28TG meet the same compliance requirements?

A: Yes. The N84C162WD28TG maintains REACH Unaffected and EAR99 classification identical to the CAT1162WI28. Additionally, it carries ROHS3 compliance certification.

Q: What is the inventory status of the substitute part?

A: The N84C162WD28TG has 846 pieces of new original stock available, ensuring reliable supply for production and replacement applications.

Q: Can both parts be used interchangeably in the same application?

A: Yes. The identical voltage monitoring threshold, output type, reset configuration, and operating temperature range make these parts fully interchangeable from an engineering perspective.
