MCP810T-270I/TT Equivalent & Substitute Parts

Part Overview

The MCP810T-270I/TT is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for reset and power-on reset applications. This Surface Mount device operates across the industrial temperature range of -40°C to 85°C and is currently in active production status. The part is ROHS3 compliant with MSL 1 rating, indicating broad compatibility with modern manufacturing processes.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Package / Case: TO-236-3, SC-59, SOT-23-3 (physical and electrical compatibility)
• Number of Voltages Monitored: 1 channel
• Output Type: Push-Pull, Totem Pole configuration
• Reset Logic: Active High
• Voltage Threshold: 2.625V ±0.005V tolerance
• Reset Timeout: 150ms minimum
• Operating Temperature Range: -40°C to 85°C minimum
• RoHS and MSL Compliance: ROHS3 Compliant, MSL 1

Parts meeting all these criteria are classified as parametric equivalents. Parts with minor deviations in non-critical parameters (such as reset timeout or upper temperature rating) are classified as manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

MCP101T-270I/TT is a parametric equivalent to MCP810T-270I/TT, manufactured by Microchip Technology. Both parts share identical electrical specifications, package configuration, and compliance certifications. This part is in active production status and represents the primary direct replacement option.

APX810-26SAG-7 (Diodes Incorporated) and MAX810RTRG (onsemi) are manufacturer-recommended alternatives. Both maintain the required SOT-23-3 package, single-channel monitoring, push-pull output, and active-high reset logic. The voltage threshold deviation (2.63V vs. 2.625V) and reset timeout reduction (140ms vs. 150ms) represent minor parameter variations within acceptable engineering tolerances for supervisor IC applications. Both parts are ROHS3 compliant with MSL 1 rating. APX810-26SAG-7 is in active production; MAX810RTRG is obsolete.

STM810RWX6F (Nexperia USA Inc.) is listed as an alternative but lacks complete specification documentation in the provided parameters, limiting full equivalency confirmation.

For new designs and production continuity, MCP101T-270I/TT is recommended as the primary substitute. For applications requiring extended temperature operation beyond 85°C, MAX810RTRG supports -40°C to 105°C operation, though its obsolete status should be considered for long-term supply planning.

Frequently Asked Questions (FAQ)

Q: Can MCP101T-270I/TT replace MCP810T-270I/TT directly in existing designs?

A: Yes. MCP101T-270I/TT is a parametric equivalent with identical electrical specifications, package configuration (SOT-23-3), voltage threshold (2.625V), reset timeout (150ms minimum), and operating temperature range (-40°C to 85°C). Both are manufactured by Microchip Technology and carry ROHS3 compliance with MSL 1 rating.

Q: What is the difference between the voltage thresholds of MCP810T-270I/TT (2.625V) and APX810-26SAG-7 (2.63V)?

A: The 0.005V difference represents a minor tolerance variation typical in supervisor IC design. Both thresholds fall within acceptable engineering margins for single-channel power monitoring applications. Circuit designers should confirm this variation does not impact specific application requirements.

Q: Why is MAX810RTRG listed as obsolete?

A: MAX810RTRG is marked as obsolete by onsemi. While it maintains electrical and package compatibility with MCP810T-270I/TT, its discontinued production status limits suitability for new designs or long-term production commitments. Active alternatives such as MCP101T-270I/TT or APX810-26SAG-7 are recommended for supply continuity.

Q: Does packaging type (Tape & Reel vs. Cut Tape vs. Bulk) affect electrical compatibility?

A: No. Packaging type affects only handling, storage, and automated assembly processes. Electrical and mechanical compatibility remain unchanged. MCP810T-270I/TT (Tape & Reel), APX810-26SAG-7 (Tape & Reel), and MAX810RTRG (Cut Tape) are electrically interchangeable within their specified parameter ranges.

Q: Can STM810RWX6F be used as a substitute?

A: STM810RWX6F is listed as an alternative but lacks complete specification data in the provided parameters. Confirmation of reset timeout, operating temperature range, and full compliance certifications is required before engineering approval for substitution.

Q: What does "Active High" reset logic mean?

A: Active High reset logic indicates the reset output is asserted (driven high) when the monitored voltage falls below the threshold. All listed substitute parts maintain this reset polarity, ensuring functional compatibility in designs expecting active-high reset behavior.
