CAT1162WI25 Equivalent & Substitute Parts

Part Overview

The CAT1162WI25 is a supervisor integrated circuit from onsemi designed for power management applications. This device functions as a Simple Reset/Power-On Reset supervisor with open drain or open collector output, monitoring a single voltage channel. The part is currently classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical characteristics and package specifications to ensure direct compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT1162WI25 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 Threshold: 2.55V 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 Specification: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Technology: Surface Mount

The substitute part N84C162WD25TG meets all these criteria and is therefore a direct functional equivalent. This part differs only in product status (Last Time Buy versus Obsolete) and packaging format (Tape & Reel versus bulk), with no impact on electrical performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The N84C162WD25TG is a direct electrical and mechanical equivalent to the CAT1162WI25. Selection between these parts should be based on the following factors:

Product Status Consideration: The CAT1162WI25 is classified as Obsolete, while N84C162WD25TG carries Last Time Buy status. For new designs or long-term production requirements, N84C162WD25TG provides extended availability and supply chain stability.

Packaging Format: The CAT1162WI25 is supplied in bulk packaging, while N84C162WD25TG is available in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and reduces handling risk during manufacturing.

Compliance Status: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring equivalent regulatory compliance for export and use in controlled applications.

Moisture Sensitivity: Both parts share MSL Level 1 (Unlimited), indicating no moisture-related storage or handling restrictions.

Frequently Asked Questions (FAQ)

Q: Can N84C162WD25TG be used as a direct replacement for CAT1162WI25 in existing designs?

A: Yes. All electrical parameters, functional specifications, and package dimensions are identical. Direct substitution is possible without circuit modification or re-qualification.

Q: What is the difference between the bulk and Tape & Reel packaging formats?

A: Bulk packaging is suitable for manual handling and small-quantity applications. Tape & Reel format is designed for automated pick-and-place assembly and provides better protection during high-volume manufacturing. Both formats contain the same die and electrical performance.

Q: Why is the CAT1162WI25 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. N84C162WD25TG, with Last Time Buy status, represents the final production run before complete discontinuation. For new designs, this part should be selected as the primary choice.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and share the same moisture sensitivity level (MSL 1). Environmental performance is equivalent.

Q: What are the critical parameters that must match for substitution?

A: Voltage threshold (2.55V), reset timeout (130ms minimum), output configuration (open drain/collector), package type (8-SOIC), and operating temperature range (-40°C to 85°C) must all match exactly. These parameters determine functional compatibility in the application circuit.
