MIC809RYC3-TR Equivalent & Substitute Parts

Part Overview

The MIC809RYC3-TR is an active low reset supervisor IC manufactured by Microchip Technology, designed for single-channel power supply monitoring in surface mount SC-70 packaging. This device belongs to the Power Management (PMIC) category and is classified as a Simple Reset/Power-On Reset supervisor with push-pull totem pole output configuration. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original MIC809RYC3-TR becomes unavailable due to supply constraints, when alternative packaging formats are required for manufacturing flexibility, or when extended operating temperature ranges are needed for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC809RYC3-TR is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters (Must Match):

• Voltage threshold: 2.63V
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active Low
• Reset timeout: 140ms Minimum
• Number of voltages monitored: 1 channel
• Type: Simple Reset/Power-On Reset

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package / Case: SC-70, SOT-323 (or compatible footprint variants)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Flexible Parameters (May Vary):

• Manufacturer (alternative suppliers acceptable)
• Operating temperature range (extended ranges acceptable if minimum -40°C and maximum ≥85°C)
• Packaging format (Tape & Reel, Cut Tape, or Digi-Reel acceptable)
• Reset timeout (values ≥140ms acceptable)
• Moisture Sensitivity Level (MSL 1 or MSL 3 acceptable for unlimited or 168-hour storage)

Substitute parts are grouped into two categories: MFR Recommended substitutes (direct manufacturer alternatives) and Parametric Equivalents (cross-manufacturer alternatives meeting all electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Package Match (SC-70-3 Footprint):

For applications requiring identical SC-70 package geometry, the following parts provide direct substitution with matching electrical specifications:

• TCM809RVLB713: Microchip Technology alternative with extended operating temperature range (-40°C ~ 125°C), maintaining 140ms reset timeout and SC-70-3 package in Tape & Reel format.
• MAX6381XR26D3+T: Maxim Integrated alternative with extended operating temperature range (-40°C ~ 125°C), matching 140ms reset timeout and SC-70-3 package in Cut Tape format.
• MAX809REXR+T: Maxim Integrated alternative with extended operating temperature range (-40°C ~ 125°C), matching 140ms reset timeout and SC-70-3 package in Tape & Reel format.
• ISL88001IE26Z-T7A: Renesas Electronics alternative with matching electrical specifications and SC-70-3 package in Tape & Reel format. MSL rating is 3 (168 hours) instead of MSL 1.

Alternative Package Format (SOT-23-3 Footprint):

For applications where PCB layout permits SOT-23-3 package substitution:

• TCM809RENB713: Microchip Technology alternative in SOT-23-3 package with matching electrical specifications, available in Cut Tape & Digi-Reel format.
• TCM809RVNB713: Microchip Technology alternative in SOT-23-3 package with extended operating temperature range (-40°C ~ 125°C), available in Tape & Reel format.

Reduced Reset Timeout Consideration:

• MAX6326XR26+T: Maxim Integrated alternative with 100ms reset timeout (shorter than the 140ms minimum of the original part). This part is suitable only for applications where the shorter reset timeout does not impact system requirements.

All listed substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the original MIC809RYC3-TR.

Frequently Asked Questions (FAQ)

Q: Can TCM809RENB713 be used as a direct replacement for MIC809RYC3-TR?

A: TCM809RENB713 is electrically equivalent but uses SOT-23-3 package instead of SC-70-3. Direct PCB substitution is not possible without layout modification. However, the electrical specifications are identical, making it suitable for new designs or boards that can accommodate the different footprint.

Q: What is the difference between TCM809RVLB713 and TCM809RVNB713?

A: Both are Microchip Technology alternatives with identical electrical specifications and extended operating temperature range (-40°C ~ 125°C). The primary difference is package format: TCM809RVLB713 uses SC-70-3 (matching the original part's footprint), while TCM809RVNB713 uses SOT-23-3. Selection depends on PCB layout requirements.

Q: Why does MAX6326XR26+T have a shorter reset timeout (100ms vs 140ms)?

A: MAX6326XR26+T is a Maxim Integrated device with inherently different reset timeout characteristics. This part is suitable only for applications where a 100ms reset timeout meets system requirements. For applications requiring 140ms or longer timeout, use MAX6381XR26D3+T or MAX809REXR+T instead.

Q: Is ISL88001IE26Z-T7A compatible with the original MIC809RYC3-TR?

A: ISL88001IE26Z-T7A is a Renesas Electronics parametric equivalent with matching electrical specifications and SC-70-3 package. The primary difference is Moisture Sensitivity Level (MSL 3 with 168-hour storage limit versus MSL 1 unlimited). This part is suitable for applications with standard moisture handling procedures.

Q: Can I use MAX809REXR+T in place of MIC809RYC3-TR without PCB modification?

A: Yes. MAX809REXR+T is a Maxim Integrated alternative with identical SC-70-3 package, matching electrical specifications, and extended operating temperature range (-40°C ~ 125°C). It provides direct footprint compatibility and can be used as a drop-in replacement.

Q: What packaging formats are available for these substitutes?

A: Substitutes are available in three packaging formats: Tape & Reel (TR) for high-volume production, Cut Tape (CT) for smaller quantities, and Digi-Reel for mixed-volume applications. Selection depends on procurement volume and manufacturing requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the original MIC809RYC3-TR for applications subject to these requirements.
