MIC707N Equivalent & Substitute Parts

Part Overview

The MIC707N is a single-channel power supply supervisor IC manufactured by Microchip Technology, designed for power-on reset and simple reset applications in 8-DIP packaging. This device monitors a single voltage threshold at 4.65V and provides complementary output logic. The MIC707N is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives from Analog Devices Inc. and Maxim Integrated offer compatible functionality with modern RoHS3 compliance and extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC707N is determined by the following critical parameters:

Core Compatibility Criteria:

• Single voltage monitoring channel
• 4.65V threshold voltage
• Active High/Active Low reset logic
• Through-hole mounting in 8-DIP package
• Operating temperature range compatibility

Substitution Logic:

All four substitute parts (ADM707ANZ, DS1707EPA+, MAX707CPA+, MAX707EPA+) meet the core electrical and mechanical requirements for direct substitution. Each maintains the single-channel supervisor architecture with 4.65V threshold monitoring and identical package footprint. The primary differences among substitutes relate to output configuration (Push-Pull vs. Complementary), reset timeout specifications, operating temperature ranges, and compliance certifications.

The ADM707ANZ, DS1707EPA+, and MAX707EPA+ support the full -40°C ~ 85°C operating range, matching the MIC707N's temperature specification. The MAX707CPA+ operates within a narrower 0°C ~ 70°C range and is suitable only for applications not requiring extended low-temperature operation.

All substitute parts are RoHS3 compliant and carry active product status, providing superior long-term availability compared to the obsolete MIC707N.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAX707EPA+

The MAX707EPA+ is the optimal substitute for new designs and production transitions. It maintains full compatibility with the MIC707N across all critical electrical parameters: 4.65V threshold, Active High/Active Low reset logic, and -40°C ~ 85°C operating range. The device carries RoHS3 compliance and active product status, ensuring long-term supply chain stability and regulatory alignment.

Alternative: ADM707ANZ

The ADM707ANZ provides equivalent functionality with the same extended temperature range (-40°C ~ 85°C) and RoHS3 compliance. This part is suitable where Analog Devices supply chain preference is established.

Alternative: DS1707EPA+

The DS1707EPA+ operates within the full temperature specification and carries RoHS3 compliance. The 130ms minimum reset timeout is shorter than the MIC707N specification but remains within acceptable supervisor IC performance parameters.

Conditional Use: MAX707CPA+

The MAX707CPA+ is suitable only for applications operating within the 0°C ~ 70°C temperature range. This part is not recommended for designs requiring the full -40°C ~ 85°C operating envelope of the original MIC707N.

Output Configuration Consideration:

All substitute parts employ Push-Pull output configuration, whereas the MIC707N uses Complementary output. Circuit designs must accommodate this output topology difference during implementation.

Frequently Asked Questions (FAQ)

Q: Can MAX707EPA+ directly replace MIC707N in existing designs?

A: The MAX707EPA+ is electrically compatible at the threshold voltage (4.65V), reset logic (Active High/Active Low), and operating temperature range (-40°C ~ 85°C). However, the output configuration differs: MAX707EPA+ uses Push-Pull output while MIC707N uses Complementary output. Circuit designs must be reviewed to confirm output stage compatibility before substitution.

Q: Why do the substitute parts have different reset timeout values?

A: Reset timeout specifications vary among supervisor IC manufacturers based on internal circuit design. The MIC707N specifies 140ms minimum, while DS1707EPA+ specifies 130ms and ADM707ANZ specifies 160ms. These variations remain within typical supervisor IC performance ranges and do not affect functional compatibility for standard power-on reset applications.

Q: Is MAX707CPA+ suitable for all MIC707N applications?

A: No. The MAX707CPA+ operates only within 0°C ~ 70°C, which is narrower than the MIC707N's -40°C ~ 85°C range. Use MAX707CPA+ only in applications confirmed to operate within this reduced temperature envelope. For full temperature range compatibility, select ADM707ANZ, DS1707EPA+, or MAX707EPA+.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts (ADM707ANZ, DS1707EPA+, MAX707CPA+, MAX707EPA+) carry RoHS3 compliance certification, whereas the MIC707N is RoHS non-compliant. This compliance advantage supports modern manufacturing and regulatory requirements.

Q: What is the package compatibility between MIC707N and substitutes?

A: All parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with 8-PDIP supplier device package designation. PCB footprints and pin assignments are mechanically compatible, enabling direct socket substitution from a physical standpoint.

Q: Which substitute offers the best long-term availability?

A: All substitute parts carry active product status. MAX707EPA+ and MAX707CPA+ are manufactured by Maxim Integrated (now part of Analog Devices), while ADM707ANZ and DS1707EPA+ are from Analog Devices. Both manufacturers maintain robust supply chains for these supervisor IC products, providing superior availability compared to the obsolete MIC707N.
