MIC810MU-TR Equivalent & Substitute Parts

Part Overview

The MIC810MU-TR is a power management integrated circuit (PMIC) supervisor manufactured by Microchip Technology, designed for single-channel power-on reset and voltage monitoring applications. This device features push-pull totem pole output configuration in a compact SOT-23-3 surface mount package. The MIC810MU-TR is currently discontinued at DiGi Electronics, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC810MU-TR is determined by strict equivalence across the following critical parameters:

• Voltage threshold: 4.38V
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active High
• Reset timeout: 140ms Minimum
• Number of voltages monitored: 1
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting type: Surface Mount
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in operating temperature range, RoHS compliance status, and product lifecycle status are noted but do not preclude functional substitution when thermal and regulatory requirements of the application permit.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TCM810MENB713

TCM810MENB713 is the preferred substitute for the discontinued MIC810MU-TR. Both parts are manufactured by Microchip Technology and maintain identical electrical specifications and package configuration. TCM810MENB713 is in active production status with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Inventory availability is substantial at 38,400 units.

Secondary Recommendations: STM810MWX6F, ADM810MARTZ-REEL7, MAX810MEUR+T, APX810-44SAG-7

These parts provide functional equivalence with identical core electrical parameters. All are in active production status and ROHS3 compliant. Selection among these alternatives depends on application-specific thermal requirements and supply chain considerations:

• STM810MWX6F (STMicroelectronics): Maintains -40°C to 85°C operating range matching the original specification.
• ADM810MARTZ-REEL7 (Analog Devices Inc.): Extends operating temperature to -40°C to 125°C, suitable for high-temperature applications.
• MAX810MEUR+T (Analog Devices Inc./Maxim Integrated): Provides -40°C to 105°C operating range with highest inventory availability at 15,237 units.
• APX810-44SAG-7 (Diodes Incorporated): Maintains -40°C to 85°C operating range with active production status.

Not Recommended for New Designs: APX810-44SRG-7

APX810-44SRG-7 carries a "Not For New Designs" product status designation and should not be selected for new applications despite functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MIC810MU-TR with TCM810MENB713 without circuit modifications?

A: Yes. TCM810MENB713 maintains identical electrical specifications including voltage threshold (4.38V), output configuration (push-pull totem pole), reset logic (active high), and reset timeout (140ms minimum). The SOT-23-3 package is mechanically and electrically compatible. No circuit modifications are required.

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

A: All substitute parts maintain the core electrical specifications required for functional equivalence. Differences exist in operating temperature range, manufacturer, product lifecycle status, and RoHS compliance. TCM810MENB713 is recommended as the primary substitute due to identical manufacturer and active production status.

Q: Why is the original MIC810MU-TR no longer available?

A: The MIC810MU-TR is discontinued at DiGi Electronics. Equivalent parts from multiple manufacturers remain in active production, providing continuity for applications requiring single-channel power-on reset supervision at 4.38V threshold.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance status reflects manufacturing process and material composition but does not alter electrical performance or functional behavior. The original MIC810MU-TR is RoHS non-compliant, while all recommended substitutes are ROHS3 compliant. Selection should account for regulatory requirements of the end application.

Q: Can I use ADM810MARTZ-REEL7 in applications requiring extended temperature operation?

A: ADM810MARTZ-REEL7 operates from -40°C to 125°C, extending the upper temperature limit beyond the original MIC810MU-TR specification (-40°C to 85°C). This part is suitable for high-temperature applications where thermal performance is a requirement. Verify that other circuit components support the extended temperature range.

Q: What packaging formats are available for these substitutes?

A: All substitute parts use the SOT-23-3 surface mount package. Packaging options vary by supplier: TCM810MENB713 and APX810-44SAG-7 are supplied in Tape & Reel (TR) format, while STM810MWX6F, ADM810MARTZ-REEL7, and MAX810MEUR+T are available in Cut Tape (CT) or Digi-Reel® formats. Verify packaging requirements for your procurement and assembly processes.
