MIC708SM-TR Equivalent & Substitute Parts

Part Overview

The MIC708SM-TR is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for reset and power-on reset applications in 8-SOIC surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The supervisor monitors a single voltage threshold at 2.93V with complementary output configuration and 140ms minimum reset timeout, operating across the industrial temperature range of -40°C to 85°C.

Substitute Part Grouping Explanation

Substitution for the MIC708SM-TR is determined by the following critical parameters:

Single voltage monitoring channel at 2.93V threshold
8-SOIC surface mount package (0.154", 3.90mm Width)
Active High/Active Low reset capability
Operating temperature range of -40°C to 85°C
Reset timeout of 140ms minimum

Substitute parts must maintain compatibility across these core electrical and mechanical specifications. Output configuration differences (complementary versus push-pull) are noted but do not prevent functional substitution in applications where the reset signal interface is compatible with the receiving circuit. Packaging format variations (Tape & Reel, Cut Tape, or Tube) do not affect electrical equivalence but impact procurement and assembly workflows.

Engineering Selection Recommendations

MIC708SMY-TR is the direct Microchip Technology equivalent with identical electrical specifications and packaging format (Tape & Reel). This part maintains the complementary output configuration of the original MIC708SM-TR and is currently in active production status with ROHS3 compliance.

For applications requiring extended industrial temperature range (-40°C to 85°C) with active product status and RoHS compliance, MAX708SESA+ and MAX708SESA+T from Analog Devices Inc./Maxim Integrated are suitable alternatives. These parts maintain the 2.93V threshold and 140ms reset timeout. The MAX708SESA+T variant is available in Cut Tape & Digi-Reel packaging with the highest inventory availability (17,400 units).

DS1708SESA+ and DS1708SESA+T&R from Analog Devices Inc./Maxim Integrated provide substitution with a 130ms minimum reset timeout (10ms shorter than the original specification) and are available in both Tube and Tape & Reel packaging formats.

For applications limited to commercial temperature range (0°C to 70°C), MAX708SCSA+ and MAX708SCSA+T are available alternatives with 140ms reset timeout and active product status.

All substitute parts share the 8-SOIC package footprint, single-channel 2.93V voltage monitoring, and Active High/Active Low reset capability. Output configuration differences (push-pull versus complementary) require circuit-level compatibility verification based on the receiving circuit's input impedance and signal requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX708SESA+ replace MIC708SM-TR directly?

A: Electrical substitution is possible. Both parts monitor a single 2.93V threshold with Active High/Active Low reset capability in 8-SOIC packaging. The MAX708SESA+ operates across -40°C to 85°C, matching the original temperature range. The output configuration differs (push-pull versus complementary), requiring verification that the receiving circuit accepts push-pull signaling. Packaging format differs (Tube versus Tape & Reel), affecting procurement and assembly processes.

Q: What is the difference between reset timeout specifications of 140ms and 130ms?

A: Reset timeout defines the minimum duration the reset signal remains active after the voltage threshold is crossed. The MIC708SM-TR and most MAX708 variants specify 140ms minimum, while DS1708 parts specify 130ms minimum. This 10ms difference may be significant in applications with strict timing requirements for system initialization sequences.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original MIC708SM-TR is RoHS non-compliant. If RoHS compliance is a procurement requirement, any of the listed substitutes satisfy this criterion.

Q: Does packaging format affect electrical performance?

A: Packaging format (Tape & Reel, Cut Tape & Digi-Reel, or Tube) does not affect electrical performance. Format selection is determined by assembly workflow requirements and procurement volume. Tape & Reel and Cut Tape formats are optimized for automated pick-and-place assembly, while Tube packaging is suitable for manual assembly or lower-volume applications.

Q: Which substitute has the highest inventory availability?

A: MAX708SESA+T has the highest inventory availability at 17,400 units in Cut Tape & Digi-Reel format. MAX708SCSA+T follows with 16,110 units. MIC708SMY-TR, the direct Microchip equivalent, has 2,749 units available in Tape & Reel format.

Q: Can I use MAX708SCSA+ for applications requiring -40°C operation?

A: No. MAX708SCSA+ and MAX708SCSA+T are rated for 0°C to 70°C operating temperature range and are not suitable for applications requiring -40°C minimum operation. Use MAX708SESA+, MAX708SESA+T, DS1708SESA+, or DS1708SESA+T&R for full industrial temperature range support.
