CAT810MSDI-GT3 Equivalent & Substitute Parts

Part Overview

The CAT810MSDI-GT3 is a Power Management IC (PMIC) supervisor device manufactured by onsemi, designed for single-channel voltage monitoring and reset signal generation. This component operates as a push-pull, totem pole output supervisor with active-high reset functionality, housed in an SC-70 surface mount package.

The CAT810MSDI-GT3 is classified as obsolete. Locating equivalent and substitute parts is necessary to support ongoing system maintenance, design updates, and production continuity where this component is specified in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CAT810MSDI-GT3 is determined by the following critical parameters:

• Voltage Threshold: 4.38V (exact match required)
• Output Configuration: Push-Pull, Totem Pole (functional equivalence)
• Reset Logic: Active High (functional equivalence)
• Package / Case: SC-70, SOT-323 (physical and electrical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification match)
• Number of Voltages Monitored: 1 (functional scope)

The identified substitute parts meet these core parameters. The CAT810MSDI-GT3 functions as a simple reset/power-on reset supervisor. Substitute parts may operate as voltage detectors or supervisors, provided they deliver equivalent electrical behavior at the specified threshold voltage and output configuration.

Engineering Selection Recommendations

MIC810MYC3-TR (Microchip Technology) is the primary substitute for the CAT810MSDI-GT3. This part maintains identical electrical specifications, including the 140ms minimum reset timeout, and is currently in active production status. The MIC810MYC3-TR is RoHS3 compliant and available in Tape & Reel packaging, supporting high-volume manufacturing environments.

MAX6379XR44+T (Analog Devices Inc./Maxim Integrated) is a secondary substitute option. This part matches all critical electrical parameters and package specifications. However, the reset timeout specification is not provided in the available data. The MAX6379XR44+T is RoHS3 compliant and currently in active production status. This part is available in Bulk packaging.

Both substitute parts are compliant with REACH regulations and carry the same ECCN and HTSUS classifications as the original component, supporting regulatory and trade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX6379XR44+T replace the CAT810MSDI-GT3 if the reset timeout is not specified?

A: The MAX6379XR44+T meets all specified electrical and physical parameters. The absence of a reset timeout specification in available data does not indicate incompatibility. System-level validation is appropriate when reset timing is critical to application performance.

Q: Are there packaging differences between the substitute parts?

A: The MIC810MYC3-TR is supplied in Tape & Reel (TR) packaging, suitable for automated assembly. The MAX6379XR44+T is supplied in Bulk packaging. Both parts use the identical SC-70, SOT-323 physical package, ensuring PCB footprint compatibility.

Q: Do the substitute parts support the same operating temperature range?

A: Yes. Both the MIC810MYC3-TR and MAX6379XR44+T operate across the -40°C ~ 85°C temperature range, matching the CAT810MSDI-GT3 specification.

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

A: The CAT810MSDI-GT3 is obsolete, while both substitute parts are in active production. Active production status ensures ongoing availability, manufacturing support, and compliance with current industry standards.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the MIC810MYC3-TR and MAX6379XR44+T are RoHS3 compliant, supporting environmental and regulatory requirements for electronic component manufacturing and distribution.
