CAT810MSDI-T3 Equivalent & Substitute Parts

Part Overview

The CAT810MSDI-T3 is a single-channel power management supervisor IC manufactured by onsemi, designed for simple reset and power-on reset applications. This device monitors a single voltage threshold at 4.38V and provides push-pull, totem pole output with active high reset signaling. The part is packaged in SC-70 (SOT-323) surface mount configuration.

The CAT810MSDI-T3 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT810MSDI-T3 is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring: Single channel with 4.38V threshold
• Output Type: Push-pull, totem pole configuration
• Reset Behavior: Active high reset with 140ms minimum timeout
• Package: SC-70 / SOT-323 surface mount
• Temperature Range: -40°C to 85°C operating specification
• Functional Classification: Simple reset/power-on reset supervisor

The substitute part MIC810MYC3-TR, manufactured by Microchip Technology, meets all these critical parameters and is functionally equivalent for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The MIC810MYC3-TR is a direct functional equivalent to the CAT810MSDI-T3 across all monitored electrical and mechanical parameters. The primary distinction is product status: the CAT810MSDI-T3 is obsolete, while the MIC810MYC3-TR is active and currently in production.

The MIC810MYC3-TR is supplied in Tape & Reel (TR) packaging format and carries RoHS3 compliance certification. Both parts share identical REACH status (REACH Unaffected) and ECCN/HTSUS classifications, ensuring regulatory alignment for applications requiring these certifications.

Selection of the MIC810MYC3-TR is appropriate for new designs, production continuity, and replacement of obsolete inventory in existing applications where the CAT810MSDI-T3 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the MIC810MYC3-TR be used as a direct replacement for the CAT810MSDI-T3?

A: Yes. Both parts are functionally equivalent across all critical parameters: single-channel voltage monitoring at 4.38V threshold, push-pull totem pole output, active high reset logic with 140ms minimum timeout, identical operating temperature range, and SC-70 package configuration. Pin-to-pin compatibility is maintained.

Q: What is the primary reason to substitute the CAT810MSDI-T3?
