MIC810SYC3-TR Equivalent & Substitute Parts

Part Overview

The MIC810SYC3-TR is a single-channel power supply supervisor IC manufactured by Microchip Technology, designed for power-on reset and supervisory functions in embedded systems. 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 currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or when functionally compatible alternatives from other manufacturers meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC810SYC3-TR are qualified based on the following critical parameters that determine functional equivalence:

• Voltage threshold: 2.93V (exact match required)
• Output configuration: Push-Pull, Totem Pole (exact match required)
• Reset logic: Active High (exact match required)
• Package type: SC-70, SOT-323 (exact match required)
• Reset timeout: 140ms minimum or greater (equal or longer timeout acceptable)
• Operating temperature range: -40°C minimum and 85°C maximum or greater (equal or wider range acceptable)
• RoHS3 compliance and MSL 1 rating (compliance required)

Three substitute parts meet these criteria: MAX6327XR29+T, MAX6382XR29D3+T, and MAX810SEXR+T, all manufactured by Analog Devices Inc./Maxim Integrated.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active production components with full RoHS3 compliance and MSL 1 ratings, meeting the compliance requirements of the MIC810SYC3-TR.

MAX6327XR29+T is functionally equivalent with identical operating temperature range (-40°C ~ 85°C) and threshold voltage. The reset timeout of 100ms minimum is shorter than the MIC810SYC3-TR specification of 140ms minimum; this represents a tighter timing constraint and may require circuit-level evaluation if reset timing is critical to system operation.

MAX6382XR29D3+T and MAX810SEXR+T both provide extended operating temperature range (-40°C ~ 125°C) and meet or exceed the 140ms minimum reset timeout specification. MAX6382XR29D3+T is supplied in Cut Tape (CT) packaging, while MAX810SEXR+T is supplied in Tape & Reel (TR) packaging, matching the original part format.

Frequently Asked Questions (FAQ)

Q: Can MAX6327XR29+T be used as a direct replacement for MIC810SYC3-TR?

A: MAX6327XR29+T meets all critical electrical parameters including threshold voltage, output configuration, reset logic, and package type. However, its reset timeout specification of 100ms minimum is shorter than the MIC810SYC3-TR requirement of 140ms minimum. Direct substitution is permissible only if system design does not depend on the longer reset timeout duration.

Q: What is the difference between MAX6382XR29D3+T and MAX810SEXR+T?

A: Both parts are functionally equivalent with identical electrical specifications and extended temperature range. The primary difference is packaging format: MAX6382XR29D3+T is supplied in Cut Tape (CT) while MAX810SEXR+T is supplied in Tape & Reel (TR). Selection depends on procurement and assembly requirements.

Q: Are all substitute parts pin-compatible with MIC810SYC3-TR?

A: All substitute parts use the SC-70, SOT-323 package, which is mechanically and electrically compatible. Pin configuration for supervisor ICs in this package class is standardized for this functional category.

Q: Do the substitute parts have the same RoHS and compliance certifications?

A: All substitute parts carry ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, matching the MIC810SYC3-TR certifications.

Q: Which substitute part has the widest operating temperature range?

A: Both MAX6382XR29D3+T and MAX810SEXR+T support -40°C ~ 125°C operating range, compared to -40°C ~ 85°C for MIC810SYC3-TR and MAX6327XR29+T. Extended temperature range may be beneficial for industrial or automotive applications.
