MIC812TU TR Equivalent & Substitute Parts

Part Overview

The MIC812TU TR is a Power Management Integrated Circuit (PMIC) supervisor with push-pull, totem pole output configuration, designed for single-channel voltage monitoring and reset control. This component operates across the industrial temperature range of -40°C to 85°C and is packaged in SOT-143 surface mount format.

The MIC812TU TR is classified as obsolete. Equivalent and substitute parts are available from multiple manufacturers with identical or superior product status, ensuring continued design support and supply chain reliability for new applications or production transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC812TU TR is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 3.08V (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)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: TO-253-4, TO-253AA (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Number of Voltages Monitored: 1 (exact match required)

All substitute parts listed below meet these criteria. Substitutes are categorized as either direct manufacturer equivalents (same base product line with different packaging or status) or parametric equivalents (different manufacturers with identical electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Transitions:

MIC812TUY-TR is the recommended primary substitute. It is manufactured by Microchip Technology (same OEM as the original part), maintains active product status, achieves ROHS3 compliance, and provides the highest design continuity with established supply chain relationships.

For Alternative Sourcing:

ADM812TARTZ-REEL7 (Analog Devices Inc.) offers the largest available inventory (36,100 units) and active product status with ROHS3 compliance. STM812TW16F (STMicroelectronics) provides an additional qualified alternative with active status and ROHS3 compliance.

For Cost-Optimized Selections:

APX812-31UG-7 (Diodes Incorporated) and MAX812TEUS+T (Analog Devices Inc./Maxim Integrated) are parametric equivalents with active product status and ROHS3 compliance. Both meet all electrical and mechanical substitution criteria.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The original MIC812TU TR is RoHS non-compliant; substitution with any listed part upgrades compliance status for new production.

Frequently Asked Questions (FAQ)

Q: Can MIC812TUY-TR be used as a direct replacement for MIC812TU TR?

A: Yes. MIC812TUY-TR is a direct Microchip Technology equivalent with identical electrical specifications (3.08V threshold, push-pull totem pole output, active high reset, 140ms timeout, -40°C to 85°C operating range) and identical SOT-143 packaging. The primary difference is product status (active vs. obsolete) and RoHS compliance upgrade (ROHS3 vs. non-compliant).

Q: Are all listed substitutes pin-compatible?

A: Yes. All substitute parts use TO-253-4 or TO-253AA package variants with SOT-143 or SOT-143-4 supplier device packages, ensuring mechanical and electrical pin compatibility for surface mount applications.

Q: What is the difference between direct manufacturer equivalents and parametric equivalents?

A: Direct manufacturer equivalents (MIC812TUY-TR) are from the same OEM as the original part and represent product line updates or packaging variants. Parametric equivalents (ADM812TARTZ-REEL7, APX812-31UG-7, MAX812TEUS+T, STM812TW16F) are from different manufacturers but meet identical electrical and mechanical specifications, enabling cross-manufacturer substitution.

Q: Does substitution require PCB layout changes?

A: No. All substitute parts maintain identical package footprints (TO-253-4, TO-253AA) and pin configurations, allowing direct PCB substitution without layout modifications.

Q: Are there inventory advantages to selecting one substitute over another?

A: ADM812TARTZ-REEL7 offers the highest available inventory (36,100 units), followed by MAX812TEUS+T (9,900 units) and STM812TW16F (5,800 units). MIC812TUY-TR provides 3,916 units, and APX812-31UG-7 provides 3,000 units. Inventory levels support volume production requirements across all listed alternatives.

Q: What certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (unlimited) for all parts. ECCN classification is EAR99 for all parts. HTSUS code is 8542.39.0001 for all PMIC supervisors listed.
