Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC810LBC3-TR are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage threshold: 4.63V (exact match required)
• Output configuration: Push-Pull, Totem Pole (functional equivalence)
• Reset logic: Active High (functional equivalence)
• Reset timeout: 140ms Minimum (exact match required)
• Package / Case: SC-70, SOT-323 (mechanical compatibility)
• Mounting type: Surface Mount (assembly compatibility)
• Number of voltages monitored: 1 (functional scope)

Acceptable Variation Parameters:

• Operating temperature range: Extended ranges (-40°C ~ 125°C) are acceptable as they encompass the original specification
• Product status: Active parts are preferred for long-term availability
• RoHS compliance: ROHS3 compliant alternatives are acceptable for new designs
• Packaging format: Tape & Reel or Bulk formats are both acceptable

The identified substitute parts meet all critical electrical parameters and mechanical requirements, ensuring direct functional replacement in existing designs.

Engineering Selection Recommendations

TCM810LVLB713 (Microchip Technology)

This part is the manufacturer-recommended substitute from Microchip Technology. It maintains identical electrical specifications to the MIC810LBC3-TR while offering extended operating temperature range (-40°C ~ 125°C) and ROHS3 compliance. As an active product with 2654 units in stock, it provides superior long-term availability and supply chain stability. Selection of this part is appropriate for both replacement applications and new designs requiring RoHS compliance.

MAX6382XR46D3+T (Analog Devices Inc./Maxim Integrated)

This alternative from Analog Devices Inc./Maxim Integrated provides equivalent electrical functionality with identical threshold voltage, output configuration, and reset timing. It features ROHS3 compliance and extended operating temperature range. With 890 units in stock and active product status, it serves as a viable cross-manufacturer substitute. This option is suitable when Microchip supply is constrained or when design flexibility permits multi-source qualification.

Frequently Asked Questions (FAQ)

Q: Can TCM810LVLB713 directly replace MIC810LBC3-TR without circuit modifications?

A: Yes. The TCM810LVLB713 maintains identical electrical specifications including 4.63V threshold voltage, push-pull totem pole output, active high reset logic, and 140ms minimum reset timeout. The extended operating temperature range (-40°C ~ 125°C) is a superset of the original specification (-40°C ~ 85°C), ensuring compatibility in all original applications.

Q: What is the difference between the two substitute parts?

A: Both TCM810LVLB713 and MAX6382XR46D3+T meet all critical electrical and mechanical requirements. The primary differences are manufacturer (Microchip vs. Analog Devices) and packaging format (Tape & Reel vs. Bulk). Selection depends on supply availability, procurement preferences, and multi-source qualification requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both TCM810LVLB713 and MAX6382XR46D3+T are ROHS3 compliant, whereas the original MIC810LBC3-TR is RoHS non-compliant. This compliance upgrade is beneficial for new designs and applications subject to RoHS regulations.

Q: Will the SC-70 package fit existing PCB layouts designed for MIC810LBC3-TR?

A: Yes. All three parts use the SC-70 (SOT-323) package with identical pin configuration and mechanical dimensions. No PCB layout modifications are required.

Q: What is the inventory status of these substitute parts?

A: TCM810LVLB713 has 2654 units in stock, and MAX6382XR46D3+T has 890 units in stock, both listed as new original inventory. These quantities support immediate procurement for both prototype and production applications.

Q: Can MAX6382XR46D3+T be used in applications originally designed for MIC810LBC3-TR?

A: Yes. The MAX6382XR46D3+T provides equivalent electrical functionality across all critical parameters. As a cross-manufacturer substitute, it is suitable for applications where supply chain diversification or design flexibility is required.
