MIC708MY-TR Equivalent & Substitute Parts

Part Overview

The MIC708MY-TR 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 and provides complementary output logic. The part is currently in active production status with 4000 units in stock.

Substitute parts are necessary when the MIC708MY-TR is unavailable, when alternative packaging formats are required, or when design specifications allow for compatible output configurations. Equivalent devices must maintain the same voltage monitoring threshold, reset timeout characteristics, and package footprint to ensure direct board-level compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Voltage threshold: 4.4V
• Number of voltages monitored: 1 channel
• Package footprint: 8-SOIC (0.154", 3.90mm Width)
• Reset logic: Active High/Active Low capability
• Mounting type: Surface Mount
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Compatible Variation Parameters:

• Output configuration: Complementary or Push-Pull outputs are functionally compatible in reset supervisor applications
• Reset timeout: Minimum 140ms is acceptable; longer timeouts (up to 160ms) do not compromise functionality
• Operating temperature range: Extended range (-40°C ~ 85°C) is compatible with standard range (0°C ~ 70°C) when application requirements permit
• Packaging format: Tape & Reel (TR), Tube, or Cut Tape (CT) & Digi-Reel® are interchangeable for procurement purposes

All substitute parts listed maintain identical voltage threshold, channel count, and physical package dimensions, ensuring direct pin-compatible replacement.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production devices with ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility with the MIC708MY-TR.

MAX708ESA+T offers the highest inventory availability (61,050 units) and maintains full parameter alignment with the original part, including extended operating temperature range and 140ms reset timeout. This part is recommended as the primary substitute when packaging format flexibility is acceptable.

MAX708ESA+ provides identical electrical specifications to the MIC708MY-TR with 4,450 units in stock, suitable for applications requiring extended temperature operation (-40°C ~ 85°C).

ADM708ARZ is compatible for applications where the extended reset timeout of 160ms does not conflict with system requirements. This part offers substantial inventory depth (31,679 units) and maintains the full operating temperature range.

MAX708CSA+ is suitable only for applications with operating temperature requirements limited to 0°C ~ 70°C. With 6,900 units available, this part is appropriate for commercial-grade systems where extended temperature operation is not required.

Frequently Asked Questions (FAQ)

Q: Can MAX708ESA+T directly replace MIC708MY-TR on the PCB? A: Yes. Both devices use identical 8-SOIC package footprints with matching pin assignments. The push-pull output configuration of the MAX708ESA+T is functionally compatible with applications designed for complementary outputs in reset supervisor circuits.

Q: What is the difference between complementary and push-pull outputs? A: Complementary outputs provide one active-high and one active-low signal from a single monitoring function. Push-pull outputs provide dual independent drivers. Both configurations support active high/active low reset logic and are compatible in single-channel supervisor applications.

Q: Is the 160ms reset timeout of ADM708ARZ acceptable as a substitute? A: The ADM708ARZ reset timeout of 160ms exceeds the MIC708MY-TR minimum of 140ms. This longer timeout is functionally compatible and does not degrade system performance in standard power-on reset applications. Verify that your system design does not require the shorter timeout specification.

Q: Can MAX708CSA+ be used in applications requiring -40°C operation? A: No. The MAX708CSA+ operating temperature range is limited to 0°C ~ 70°C. Use MAX708ESA+, MAX708ESA+T, or ADM708ARZ for applications requiring extended temperature operation down to -40°C.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), matching the environmental and regulatory specifications of the MIC708MY-TR.

Q: What packaging formats are available for these supervisor ICs? A: MIC708MY-TR is supplied in Tape & Reel format. Substitute parts are available in Tube (ADM708ARZ, MAX708CSA+, MAX708ESA+) or Cut Tape & Digi-Reel® (MAX708ESA+T) formats. All formats are suitable for automated assembly processes.
