CAT810LSDI-T3 Equivalent & Substitute Parts

Part Overview

The CAT810LSDI-T3 is a single-channel power supply supervisor IC manufactured by onsemi, designed for simple reset and power-on reset applications. This device monitors a single voltage threshold at 4.63V and provides push-pull, totem pole output with active high reset signaling. The component is housed in an SC-70 (SOT-323) surface mount package.

The CAT810LSDI-T3 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT810LSDI-T3 is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel
• Voltage threshold of 4.63V
• Push-pull, totem pole output configuration
• Active high reset logic
• 140ms minimum reset timeout
• SC-70 (SOT-323) surface mount package
• Operating temperature range of -40°C to 85°C
• Moisture sensitivity level MSL 1

The MIC810LYC3-TR manufactured by Microchip Technology meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement in applications currently using the CAT810LSDI-T3.

Parameter Comparison

Engineering Selection Recommendations

The MIC810LYC3-TR is the recommended substitute for the CAT810LSDI-T3. Both components are REACH Unaffected and classified under ECCN EAR99, ensuring equivalent regulatory compliance. The MIC810LYC3-TR carries active product status from Microchip Technology, providing assured long-term availability and supply chain continuity compared to the obsolete onsemi part.

The MIC810LYC3-TR is supplied in Tape & Reel (TR) packaging, which is standard for production environments. All electrical and mechanical parameters are identical, including the SC-70-3 package footprint, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the MIC810LYC3-TR be used as a direct replacement for the CAT810LSDI-T3?

A: Yes. The MIC810LYC3-TR is a parametric equivalent. All critical specifications—voltage threshold, output configuration, reset logic, timeout duration, temperature range, and package type—are identical. No circuit redesign is required.

Q: Are there any package differences between these parts?

A: Both parts use the SC-70 (SOT-323) surface mount package with SC-70-3 supplier device package designation. The footprint and pin configuration are identical, allowing direct PCB substitution.

Q: What is the significance of the product status difference?

A: The CAT810LSDI-T3 is obsolete, meaning onsemi no longer manufactures or supports this part. The MIC810LYC3-TR is active, ensuring continued availability, technical support, and supply chain reliability from Microchip Technology.

Q: Are there compliance or certification differences?

A: Both parts are REACH Unaffected and classified as EAR99 under export control regulations. The MIC810LYC3-TR additionally carries RoHS3 compliance certification, providing enhanced environmental compliance documentation.

Q: What packaging format should be specified for procurement?

A: The MIC810LYC3-TR is available in Tape & Reel (TR) format, which is standard for automated assembly and production environments. Specify MIC810LYC3-TR when ordering to ensure correct packaging.
