CAT1162WI-45-G Equivalent & Substitute Parts

Part Overview

The CAT1162WI-45-G is a supervisor integrated circuit from onsemi designed for power management applications. It functions as a Simple Reset/Power-On Reset device with open drain or open collector output configuration, monitoring a single voltage channel at a 4.5V threshold. The device is packaged in an 8-SOIC surface mount package and operates across the industrial temperature range of -40°C to 85°C.

This part carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs or ongoing production requirements. The substitute part identified maintains electrical and mechanical compatibility while offering improved availability and product lifecycle status.

Substitute Part Grouping Explanation

Substitution of the CAT1162WI-45-G is based on strict equivalence across the following critical parameters:

• Functional Type: Both parts operate as Simple Reset/Power-On Reset supervisors
• Voltage Monitoring: Single channel configuration at 4.5V threshold
• Output Stage: Open drain or open collector output
• Reset Behavior: Active High/Active Low reset capability
• Reset Timeout: 130ms minimum specification
• Temperature Range: -40°C to 85°C operating range
• Package Specification: 8-SOIC surface mount package with identical 0.154" (3.90mm) width
• Electrical Classification: Both classified as Power Management (PMIC) devices
• Environmental Compliance: REACH Unaffected and EAR99 ECCN classification

The substitute part N84C162WD45TG maintains complete electrical and mechanical compatibility with the original CAT1162WI-45-G, differing only in packaging format (Tape & Reel versus bulk) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The N84C162WD45TG is a direct functional equivalent to the CAT1162WI-45-G for all electrical and mechanical applications. Selection between these parts should be based on the following factors:

Product Lifecycle Consideration: The CAT1162WI-45-G carries Obsolete status, indicating end-of-life designation. The N84C162WD45TG is classified as Last Time Buy, providing a defined window for procurement before complete discontinuation.

Compliance Status: The N84C162WD45TG explicitly declares ROHS3 compliance, whereas the original part does not specify RoHS status. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Packaging Format: The substitute part is supplied in Tape & Reel format, which is standard for automated assembly processes. The original part packaging format is not specified. This difference does not affect electrical performance or pin compatibility.

Inventory Availability: Current stock levels show 704 units of N84C162WD45TG available versus 614 units of CAT1162WI-45-G, providing adequate supply for production requirements.

For new designs or production continuation, the N84C162WD45TG is the appropriate selection due to its active product lifecycle status and explicit RoHS3 compliance declaration.

Frequently Asked Questions (FAQ)

Q: Are the CAT1162WI-45-G and N84C162WD45TG pin-compatible?

A: Yes. Both devices use the 8-SOIC package with identical 0.154" (3.90mm) width and pin configuration. Direct PCB substitution is possible without layout modifications.

Q: What is the difference between the two part numbers?

A: The parts are electrically and mechanically identical across all specified parameters. The primary differences are product lifecycle status (Obsolete versus Last Time Buy) and packaging format (unspecified versus Tape & Reel). The N84C162WD45TG also explicitly declares ROHS3 compliance.

Q: Can I use N84C162WD45TG as a drop-in replacement for CAT1162WI-45-G?

A: Yes. All electrical specifications, operating parameters, and package dimensions are identical. The device functions identically in the same circuit application.

Q: What does "Last Time Buy" status mean for the N84C162WD45TG?

A: Last Time Buy indicates a defined final procurement period before the manufacturer discontinues the part. This status provides a known timeline for securing inventory before complete end-of-life.

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

A: No. Both parts operate across -40°C to 85°C and monitor a single 4.5V threshold with identical reset timeout specifications of 130ms minimum.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a packaging and delivery format for automated assembly. It does not affect the electrical characteristics or performance of the integrated circuit itself.

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the device meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials in electrical and electronic equipment. This is relevant for applications subject to environmental regulations.
