Substitute Part Grouping Explanation

Substitution for the CAT1162WI-25-G is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor
• Voltage Monitoring Channels: Single channel (1)
• Voltage Threshold: 2.55V
• Output Type: Open Drain or Open Collector
• Reset Polarity: Active High/Active Low capability
• Reset Timeout Duration: 130ms Minimum
• Operating Temperature Range: -40°C ~ 85°C
• Package Format: 8-SOIC (0.154", 3.90mm Width)
• Mounting Technology: Surface Mount

The substitute part N84C162WD25TG meets all these criteria and is manufactured by onsemi, ensuring design and functional compatibility with the original CAT1162WI-25-G specification.

Parameter Comparison

Engineering Selection Recommendations

The N84C162WD25TG is the direct functional equivalent for the CAT1162WI-25-G supervisor IC. Both parts share identical electrical specifications, threshold voltage, output configuration, and package geometry. The substitute part carries Last Time Buy status with ROHS3 compliance certification, providing regulatory alignment for new designs and production continuity.

The primary distinction between the two parts is packaging format: the original CAT1162WI-25-G is supplied in bulk packaging, while the N84C162WD25TG is available in Tape & Reel format. This difference does not affect electrical or mechanical compatibility and reflects standard industry supply chain practices for components in their lifecycle transition.

Frequently Asked Questions (FAQ)

Q: Can N84C162WD25TG be used as a direct replacement for CAT1162WI-25-G in existing designs?

A: Yes. Both parts are functionally identical across all electrical parameters, voltage thresholds, output types, reset timing, and package specifications. The 8-SOIC package dimensions and pin configuration are identical, enabling direct PCB substitution.

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

A: Bulk packaging is used for manual handling and smaller production volumes, while Tape & Reel format is standard for automated assembly processes. The components themselves are electrically and mechanically identical; the difference is only in supply and handling method.

Q: Why is the original CAT1162WI-25-G marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The N84C162WD25TG, marked as Last Time Buy, represents the final production run before complete discontinuation. For new designs and long-term supply assurance, the N84C162WD25TG should be specified.

Q: Are there compliance differences between the two parts?

A: The N84C162WD25TG carries ROHS3 compliance certification, meeting current environmental and regulatory standards. The original CAT1162WI-25-G compliance status is not specified in the available data. For applications requiring documented RoHS compliance, the N84C162WD25TG is the appropriate selection.

Q: Is the 130ms reset timeout specification identical between both parts?

A: Yes. Both the CAT1162WI-25-G and N84C162WD25TG maintain a 130ms minimum reset timeout, ensuring equivalent system reset behavior and timing characteristics.
