Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC810TYC3-TR are qualified based on the following critical parameters that must remain constant or compatible:

• Single voltage monitoring channel
• Voltage threshold of 3.08V
• Push-pull, totem-pole output configuration
• Active-high reset logic
• 140ms minimum reset timeout
• SC-70 / SOT-323 package footprint
• Surface mount technology
• RoHS3 compliance
• MSL 1 rating

The primary substitute identified is TCM810TVLB713, which maintains all functional and electrical parameters while offering an extended operating temperature range of -40°C to 125°C, compared to the standard -40°C to 85°C range of the MIC810TYC3-TR. Both parts are manufactured by Microchip Technology and share identical packaging, threshold voltage, output configuration, and reset characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TCM810TVLB713 is a direct functional equivalent to the MIC810TYC3-TR with identical electrical specifications and package footprint. Selection between these parts should be based on application operating temperature requirements. The MIC810TYC3-TR is suitable for standard industrial temperature range applications (-40°C to 85°C). The TCM810TVLB713 extends the upper operating temperature limit to 125°C, making it appropriate for high-temperature environments or applications requiring extended thermal margin.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture bake-out requirements. Inventory availability should be considered as a secondary factor; the TCM810TVLB713 currently has 1017 units in stock compared to 991 units for the MIC810TYC3-TR.

Frequently Asked Questions (FAQ)

Q: Can TCM810TVLB713 be used as a direct replacement for MIC810TYC3-TR in all applications?

A: Yes, TCM810TVLB713 is functionally equivalent with identical voltage threshold, output configuration, reset logic, and package footprint. The extended temperature range of TCM810TVLB713 (-40°C to 125°C versus -40°C to 85°C) makes it suitable for all applications where MIC810TYC3-TR is used, with additional capability for high-temperature environments.

Q: Are there any PCB layout or schematic changes required when substituting TCM810TVLB713 for MIC810TYC3-TR?

A: No. Both parts use identical SC-70 / SOT-323 package footprints and pin configurations. No PCB layout modifications or schematic changes are necessary.

Q: What is the significance of the 140ms minimum reset timeout specification?

A: The 140ms reset timeout defines the minimum duration the reset output remains asserted after power supply stabilization. This parameter is identical across both parts and ensures consistent system initialization timing.

Q: Do both parts require the same moisture handling procedures?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard ESD precautions apply, but no special moisture bake-out or dry storage requirements exist.

Q: What is the difference between push-pull and totem-pole output configurations?

A: Push-pull, totem-pole output means the reset signal actively drives both high and low logic states through complementary transistor pairs, providing strong drive capability and fast switching transitions compared to open-drain outputs.
