Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC810MBC3-TR are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Package / Case: SC-70, SOT-323 (physical and electrical compatibility)
• Number of Voltages Monitored: 1 channel
• Voltage - Threshold: 4.38V (functional equivalence)
• Output Configuration: Push-Pull, Totem Pole
• Reset Logic: Active High
• Reset Timeout: 140ms Minimum or lower (functional compatibility)
• Mounting Type: Surface Mount

Identified Substitutes:

TCM810MVLB713 (Microchip Technology) meets all critical parameters with identical electrical specifications and enhanced temperature range (-40°C ~ 125°C). Product status is Active with ROHS3 compliance.

MAX6347XR44+T (Analog Devices Inc./Maxim Integrated) meets all critical parameters with identical electrical specifications. Reset timeout specification is 100ms Minimum, which is lower than the 140ms requirement and therefore functionally compatible. Product status is Active with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

TCM810MVLB713 is the primary substitute for the MIC810MBC3-TR. Both parts are manufactured by Microchip Technology and share identical electrical specifications. TCM810MVLB713 offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) and achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Packaging and functional characteristics are identical. This part is currently in active production status with substantial inventory availability.

MAX6347XR44+T is an alternative substitute manufactured by Analog Devices Inc./Maxim Integrated. It maintains electrical equivalence across all critical parameters, including voltage threshold, output configuration, and reset logic. The reset timeout specification of 100ms Minimum is lower than the 140ms Minimum of the original part, providing functional compatibility. MAX6347XR44+T achieves ROHS3 compliance and is in active production status. This option provides cross-manufacturer diversity for supply chain resilience.

Both substitutes maintain SC-70, SOT-323 package compatibility, ensuring direct PCB-level replacement without layout modifications. Selection between TCM810MVLB713 and MAX6347XR44+T should be based on supply chain availability, cost considerations, and manufacturer preference within system design constraints.

Frequently Asked Questions (FAQ)

Q: Can TCM810MVLB713 directly replace MIC810MBC3-TR on existing PCBs?

A: Yes. TCM810MVLB713 is packaged in SC-70, SOT-323 with identical pinout and electrical specifications. No PCB modifications are required for direct substitution.

Q: What is the significance of the extended temperature range in TCM810MVLB713?

A: TCM810MVLB713 operates from -40°C to 125°C, compared to -40°C to 85°C for MIC810MBC3-TR. This extended range provides operational margin in high-temperature environments and is relevant only if system thermal requirements exceed 85°C.

Q: Is MAX6347XR44+T functionally equivalent despite the lower reset timeout specification?

A: Yes. MAX6347XR44+T specifies a 100ms Minimum reset timeout, which is lower than the 140ms Minimum of MIC810MBC3-TR. In reset timing applications, a shorter timeout is functionally compatible and does not create incompatibility. The part meets all other electrical and mechanical requirements.

Q: What are the RoHS compliance implications of these substitutes?

A: MIC810MBC3-TR is RoHS non-compliant. Both TCM810MVLB713 and MAX6347XR44+T are ROHS3 compliant. If system design requires RoHS compliance, either substitute addresses this requirement. If legacy RoHS non-compliant designs are required, MIC810MBC3-TR specifications must be maintained.

Q: Are there packaging differences between the three parts?

A: All three parts use SC-70, SOT-323 packaging. Tape & Reel (TR) and Cut Tape (CT) designations refer to supply format only and do not affect electrical or mechanical compatibility. Both formats are suitable for automated assembly.

Q: Which substitute should be selected for new designs?

A: For new designs, either TCM810MVLB713 or MAX6347XR44+T is appropriate. TCM810MVLB713 maintains Microchip Technology manufacturer continuity. MAX6347XR44+T provides cross-manufacturer sourcing options. Both are in active production with ROHS3 compliance. Selection should be based on supply chain availability, cost, and design team preference.
