MIC706RN Equivalent & Substitute Parts

Part Overview

The MIC706RN is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for power-on reset and voltage monitoring applications. This device operates as a simple reset controller with active-low output and a 140ms minimum reset timeout. The MIC706RN is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC706RN are qualified based on the following critical parameters that determine functional equivalence:

• Single-channel voltage monitoring: Both substitute parts maintain 1-channel supervisor functionality
• Voltage threshold: 2.63V threshold maintained across all parts
• Reset polarity: Active-low reset output required
• Package compatibility: 8-DIP (0.300", 7.62mm) form factor for direct board-level replacement
• Operating temperature range: -40°C ~ 85°C maintained
• Through-hole mounting: Consistent with original design

The two identified substitutes—ADM706RANZ and DS1706REPA+—meet these core electrical and mechanical requirements. Both are manufactured by Analog Devices Inc. (with DS1706REPA+ also attributed to Maxim Integrated) and provide equivalent supervisor functionality with compatible pinouts and package specifications.

Engineering Selection Recommendations

ADM706RANZ is the primary recommended substitute. This part is currently in active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance, meeting modern environmental and regulatory requirements. The push-pull totem-pole output configuration provides enhanced drive capability compared to the original MIC706RN specification. Reset timeout of 160ms exceeds the minimum 140ms requirement of the original part.

DS1706REPA+ serves as a secondary alternative. Although classified as obsolete, it remains available in inventory. This part also meets ROHS3 compliance standards and features a push-pull totem-pole output. The reset timeout of 130ms is shorter than the original specification but remains within acceptable margins for most applications requiring the 2.63V threshold supervisor function.

For new designs or long-term production support, ADM706RANZ is the preferred selection due to active product status and guaranteed availability.

Frequently Asked Questions (FAQ)

Q: Can ADM706RANZ directly replace MIC706RN in existing designs? A: Yes. Both parts share identical voltage threshold (2.63V), reset polarity (active low), package form factor (8-DIP), and operating temperature range (-40°C ~ 85°C). The push-pull totem-pole output of ADM706RANZ is compatible with designs expecting active-low reset signaling.

Q: What is the significance of the reset timeout difference between these parts? A: Reset timeout defines the minimum duration the reset output remains asserted after power supply stabilization. MIC706RN specifies 140ms minimum, ADM706RANZ provides 160ms, and DS1706REPA+ provides 130ms. All values are within typical system requirements for microprocessor and FPGA reset sequencing.

Q: Why is ADM706RANZ recommended over DS1706REPA+ despite both being functionally equivalent? A: ADM706RANZ holds active product status, ensuring continued manufacturing and supply availability. DS1706REPA+ is obsolete, presenting potential long-term sourcing challenges. For new designs and production continuity, active-status parts are preferred.

Q: Are there package or pinout differences between these supervisor ICs? A: No. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with compatible pinouts, enabling direct board-level substitution without layout modifications.

Q: What compliance differences exist between MIC706RN and its substitutes? A: MIC706RN is RoHS non-compliant. Both ADM706RANZ and DS1706REPA+ are ROHS3 compliant, meeting current environmental regulations. All three parts maintain MSL 1 (unlimited moisture sensitivity) classification.
