MIC708MY Equivalent & Substitute Parts

Part Overview

The MIC708MY is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for power-on reset and simple reset applications. This device monitors a single voltage threshold at 4.4V and provides complementary output logic. The MIC708MY is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when designs require alternative sourcing, higher inventory availability, extended temperature range support, or different output configurations while maintaining core supervisory functionality across the 8-SOIC package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC708MY is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging
• Voltage Threshold: All parts must monitor 4.4V threshold
• Functional Type: All parts must provide simple reset/power-on reset supervision with active high/active low reset logic
• Single Channel Monitoring: All parts must monitor exactly one voltage
• Compliance: All parts must maintain RoHS3 compliance and MSL 1 rating

The identified substitute parts meet these core criteria. Output configuration differences (complementary versus push-pull) and reset timeout variations (140ms versus 160ms) represent acceptable engineering trade-offs within the supervisor IC category, as both configurations deliver the required reset signal generation and voltage monitoring function.

Parameter Comparison

Engineering Selection Recommendations

MAX708ESA+T is the primary substitute option, offering identical reset timeout (140ms), full temperature range (-40°C ~ 85°C), and highest inventory availability (61,050 pcs). This part is available in Cut Tape and Digi-Reel packaging, providing flexibility for both prototype and production volume requirements.

MAX708ESA+ provides equivalent electrical specifications to MAX708ESA+T with identical timeout and temperature range, differentiated only by Tube packaging format and lower inventory (4,450 pcs).

MAX708CSA+ is suitable for applications with restricted operating temperature requirements (0°C ~ 70°C). This part maintains 140ms reset timeout and push-pull output configuration with 6,900 pcs inventory availability.

ADM708ARZ offers full temperature range (-40°C ~ 85°C) and highest inventory among Analog Devices options (31,679 pcs). The 160ms reset timeout represents a 20ms extension compared to MIC708MY; this difference is acceptable for applications where extended power-on reset timing does not conflict with system requirements.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and 8-SOIC package compatibility required for direct PCB footprint substitution.

Frequently Asked Questions (FAQ)

Q: Can MAX708ESA+T directly replace MIC708MY on existing PCBs?

A: Yes. Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. Electrical pinout compatibility is maintained across all substitute options listed. Verify circuit design accommodates push-pull output configuration if substituting from MIC708MY complementary output.

Q: What is the significance of the 160ms reset timeout in ADM708ARZ versus 140ms in other parts?

A: Reset timeout defines the minimum duration the reset output remains asserted after voltage threshold detection. The 20ms difference in ADM708ARZ does not affect functional compatibility for standard power-on reset applications. Confirm system timing requirements do not mandate the shorter 140ms specification before selecting ADM708ARZ.

Q: Are there temperature range restrictions when selecting a substitute?

A: MAX708CSA+ operates within 0°C ~ 70°C range, narrower than MIC708MY (-40°C ~ 85°C). Applications requiring extended temperature operation must select ADM708ARZ, MAX708ESA+, or MAX708ESA+T, all rated -40°C ~ 85°C.

Q: What packaging format differences exist among substitute parts?

A: MIC708MY, ADM708ARZ, MAX708CSA+, and MAX708ESA+ are supplied in Tube packaging. MAX708ESA+T is available in Cut Tape (CT) and Digi-Reel format, suitable for automated pick-and-place assembly and high-volume production environments.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All listed substitute parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating, matching MIC708MY compliance profile.

Q: What output configuration difference exists between MIC708MY and substitute parts?

A: MIC708MY provides complementary output logic. All substitute parts (ADM708ARZ, MAX708CSA+, MAX708ESA+, MAX708ESA+T) provide push-pull output configuration. Both configurations deliver active high/active low reset signaling; verify circuit design compatibility with push-pull output before substitution.
