MIC810RU-TR Equivalent & Substitute Parts

Part Overview

The MIC810RU-TR is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for reset and power-on reset applications. This device features push-pull totem pole output with a 2.63V threshold and 140ms minimum reset timeout. The MIC810RU-TR is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from multiple manufacturers provide functional equivalence while maintaining the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC810RU-TR is determined by strict adherence to the following electrical and mechanical parameters:

• Voltage Threshold: 2.63V (exact match required)
• Output Configuration: Push-Pull, Totem Pole (exact match required)
• Reset Logic: Active High (exact match required)
• Reset Timeout: 140ms Minimum (exact match required)
• Number of Voltages Monitored: 1 (exact match required)
• Package / Case: TO-236-3, SC-59, SOT-23-3 or SOT23R (mechanically compatible)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C minimum and equal or higher maximum temperature

All substitute parts listed meet these criteria. Substitute parts are grouped by relationship type: direct manufacturer variants, manufacturer-recommended alternatives, and parametric equivalents from alternative suppliers.

Engineering Selection Recommendations

Direct Manufacturer Upgrade: MIC810RUY-TR is the recommended primary substitute. This part is manufactured by Microchip Technology, the original manufacturer of the MIC810RU-TR, and maintains identical electrical specifications while offering ROHS3 compliance and active product status.

Manufacturer-Recommended Alternatives: ADM810RARTZ-REEL7 and MAX810REUR+T are manufacturer-recommended substitutes from Analog Devices Inc. Both parts are ROHS3 compliant and active. ADM810RARTZ-REEL7 supports an extended operating temperature range of -40°C ~ 125°C. MAX810REUR+T offers the highest inventory availability (159,600 units) and supports -40°C ~ 105°C operating range.

Parametric Equivalents: APX810-26SAG-7 and APX810-26SRG-7 from Diodes Incorporated are parametric equivalents meeting all electrical specifications. Both are ROHS3 compliant and active. APX810-26SRG-7 uses SOT23R packaging, which is mechanically compatible with SOT-23-3. APX810-26SRG-7 offers the highest inventory availability among parametric equivalents (18,300 units).

Alternative Supplier Option: STM810RWX6F from Nexperia USA Inc. is available in bulk packaging with substantial inventory (6,200 units) and active product status.

Frequently Asked Questions (FAQ)

Q: Can I use MIC810RUY-TR as a direct replacement for MIC810RU-TR?

A: Yes. MIC810RUY-TR is a direct substitute from the same manufacturer with identical electrical specifications. The primary difference is packaging format (Tape & Reel vs. bulk) and ROHS3 compliance status.

Q: What is the difference between the Microchip and Analog Devices versions?

A: All versions maintain the same 2.63V threshold, push-pull totem pole output, active high reset, and 140ms minimum reset timeout. Operating temperature ranges vary: Microchip MIC810RUY-TR operates -40°C ~ 85°C, while ADM810RARTZ-REEL7 extends to -40°C ~ 125°C and MAX810REUR+T to -40°C ~ 105°C. Select based on your application's temperature requirements.

Q: Are APX810-26SAG-7 and APX810-26SRG-7 interchangeable?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging: APX810-26SAG-7 uses SOT-23-3 while APX810-26SRG-7 uses SOT23R. Both are mechanically compatible with the original SOT-23-3 footprint. Verify PCB layout compatibility before selection.

Q: Does the MIC810RU-TR discontinuation affect long-term availability?

A: Yes. The original MIC810RU-TR is discontinued. MIC810RUY-TR from Microchip Technology is the recommended long-term solution, offering active product status and ROHS3 compliance. Alternative suppliers (Analog Devices, Diodes Incorporated, Nexperia) provide additional sourcing options.

Q: What RoHS compliance should I specify for new designs?

A: For new designs, specify ROHS3-compliant parts. MIC810RUY-TR, ADM810RARTZ-REEL7, MAX810REUR+T, APX810-26SAG-7, and APX810-26SRG-7 all meet ROHS3 requirements.

Q: How do I select between multiple active substitutes?

A: Selection criteria: (1) Operating temperature range required by your application, (2) Packaging preference (Tape & Reel vs. bulk), (3) Supplier inventory and lead time, (4) RoHS compliance requirements. All listed parts meet the core electrical specifications of the MIC810RU-TR.
