MIC809SYC3-TR Equivalent & Substitute Parts

Part Overview

The MIC809SYC3-TR is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for reset and power-on reset applications. This device operates as a push-pull, totem pole output supervisor with a 2.93V threshold voltage and 140ms minimum reset timeout. The part is actively produced and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable power supply monitoring.

Substitute parts become necessary when the original MIC809SYC3-TR is unavailable, when alternative packaging formats are required for manufacturing optimization, or when extended operating temperature ranges are needed for specific application environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC809SYC3-TR is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage threshold: 2.93V
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active Low
• Reset timeout: 140ms Minimum
• Number of voltages monitored: 1
• Mounting type: Surface Mount
• Package compatibility: SC-70 or SOT-23-3 (both 3-pin configurations)

Flexible Parameters:

• Operating temperature range (may be extended)
• Packaging format (Tape & Reel vs. Cut Tape)
• Manufacturer (cross-manufacturer substitutes allowed if parameters match)

Substitute parts are grouped into two categories: Microchip Technology variants with different packaging and temperature ratings, and cross-manufacturer equivalents from Analog Devices Inc./Maxim Integrated that meet identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications and functional characteristics as the MIC809SYC3-TR. Selection should be based on the following criteria:

For SC-70 Package Continuity: TCM809SVLB713 and MIC809-5SYC3-TR maintain the same SC-70 package format. TCM809SVLB713 offers extended temperature range (-40°C ~ 125°C) while MIC809-5SYC3-TR maintains the original -40°C ~ 85°C range.

For SOT-23-3 Package Alternative: TCM809SENB713 and TCM809SVNB713 provide SOT-23-3 packaging in Cut Tape format. TCM809SVNB713 includes extended temperature capability (-40°C ~ 125°C).

For Cross-Manufacturer Equivalents: MAX6381XR29D3+T and MAX809SEXR+T from Analog Devices Inc./Maxim Integrated meet all electrical parameters with extended operating temperature ranges (-40°C ~ 125°C). Both are ROHS3 compliant and carry identical compliance certifications.

All substitute parts are Active status products with ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can TCM809SENB713 replace MIC809SYC3-TR directly on the PCB?

A: TCM809SENB713 is electrically equivalent but uses SOT-23-3 packaging instead of SC-70. Both are 3-pin surface mount packages with identical pin functionality. PCB layout modification is required to accommodate the different package footprint.

Q: What is the difference between TCM809SVLB713 and TCM809SVNB713?

A: Both parts are functionally identical with 2.93V threshold and 140ms reset timeout. TCM809SVLB713 uses SC-70 packaging in Tape & Reel format, while TCM809SVNB713 uses SOT-23-3 packaging in Cut Tape format. Both offer extended temperature range to 125°C.

Q: Are Maxim Integrated MAX809SEXR+T and MAX6381XR29D3+T suitable for the same application?

A: Both Maxim parts meet the MIC809SYC3-TR electrical specifications with identical 2.93V threshold, push-pull output, and 140ms reset timeout. MAX809SEXR+T is available in Cut Tape format, while MAX6381XR29D3+T is in Tape & Reel format. Selection depends on packaging requirements.

Q: Does extended temperature range (-40°C ~ 125°C) affect circuit performance?

A: Extended temperature range parts (TCM809SVLB713, TCM809SVNB713, MAX6381XR29D3+T, MAX809SEXR+T) maintain identical electrical specifications across the wider temperature band. They are suitable for applications requiring operation beyond 85°C.

Q: What packaging format should I choose for high-volume production?

A: Tape & Reel (TR) format is standard for automated assembly lines. Cut Tape (CT) & Digi-Reel® format is suitable for lower-volume or mixed-component pick-and-place operations. Electrical performance is identical between formats.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant with MSL 1 rating and REACH unaffected status, matching the compliance profile of the MIC809SYC3-TR.
