CAT810TSDI-T3 Equivalent & Substitute Parts

Part Overview

The CAT810TSDI-T3 is a single-channel power supply supervisor IC manufactured by onsemi, designed for simple reset and power-on reset applications. This component monitors a single voltage threshold at 3.08V and provides push-pull, totem pole output with active high reset signaling. The device operates across the industrial temperature range of -40°C to 85°C and is packaged in SC-70 (SOT-323) surface mount configuration.

The CAT810TSDI-T3 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this supervisor IC.

Substitute Part Grouping Explanation

Substitution eligibility for the CAT810TSDI-T3 is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Specification: Single channel with 3.08V threshold
• Output Type: Push-pull, totem pole configuration
• Reset Behavior: Active high reset with 140ms minimum timeout
• Operating Temperature Range: -40°C to 85°C
• Package Format: SC-70 (SOT-323) surface mount
• Functional Classification: Simple reset/power-on reset supervisor

The MIC810TYC3-TR manufactured by Microchip Technology meets all substitution criteria. This part maintains identical electrical specifications, output characteristics, and thermal operating range. Both components share the same base product architecture (CAT810 / MIC810 series) and are housed in equivalent SC-70-3 packaging suitable for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The MIC810TYC3-TR is the direct functional equivalent for the obsolete CAT810TSDI-T3. Selection of the Microchip substitute is supported by:

Product Status: The MIC810TYC3-TR maintains active product status, ensuring ongoing availability and manufacturer support. The CAT810TSDI-T3 is obsolete, making the Microchip alternative the appropriate choice for new procurement and design continuity.

Regulatory Compliance: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, confirming equivalent regulatory standing for export and supply chain purposes.

Packaging and Moisture Sensitivity: Both components share SC-70-3 packaging with MSL 1 (Unlimited) rating, confirming direct board-level compatibility without additional handling or storage requirements.

Electrical Equivalence: Identical voltage threshold, output configuration, reset behavior, and operating temperature range ensure functional interchangeability in existing circuit designs without modification.
