DS1706EPA Equivalent & Substitute Parts

Part Overview

The DS1706EPA is a single-channel power management supervisor IC from Analog Devices Inc./Maxim Integrated, designed for reset and power-on reset applications. This device operates as a push-pull, totem pole output supervisor with a 4.4V threshold and 130ms minimum reset timeout. The DS1706EPA is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1706EPA are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

Critical Matching Parameters:

• Single-channel voltage monitoring architecture
• 4.4V threshold voltage
• Push-pull, totem pole output configuration
• Active low reset logic
• 8-DIP through-hole package (0.300", 7.62mm)
• Operating temperature range -40°C ~ 85°C

Allowable Variation Parameters:

• Reset timeout: DS1706EPA specifies 130ms minimum; ADM706ANZ specifies 160ms minimum (both within acceptable supervisor timing margins)
• Product status: Active alternatives available to replace obsolete devices
• RoHS compliance: Newer alternatives meet ROHS3 compliance standards
• Packaging format: Tube or bulk packaging options available

The DS1706EPA+ serves as a parametric equivalent with identical electrical specifications and reset timeout. The ADM706ANZ functions as a manufacturer-recommended substitute with equivalent core functionality and slightly extended reset timeout, offering active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

DS1706EPA+ (Parametric Equivalent): Use this part for direct replacement in existing designs where the original DS1706EPA is no longer available. The DS1706EPA+ maintains identical electrical specifications, including the 130ms reset timeout and 4.4V threshold. This part achieves ROHS3 compliance, improving supply chain sustainability. Both parts share obsolete status; however, DS1706EPA+ offers improved regulatory alignment.

ADM706ANZ (Manufacturer-Recommended Substitute): Select this part for new designs or when long-term availability is required. The ADM706ANZ carries active product status, ensuring continued manufacturing and supply chain support. This device meets ROHS3 compliance standards. The reset timeout extends to 160ms minimum, which remains compatible with standard supervisor applications. The ADM706ANZ is the preferred choice for applications requiring regulatory compliance and sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can the ADM706ANZ replace the DS1706EPA in existing designs? A: Yes. The ADM706ANZ provides equivalent functionality across all critical parameters: single-channel monitoring, 4.4V threshold, push-pull totem pole output, active low reset, and 8-DIP through-hole package. The extended reset timeout (160ms vs. 130ms) is compatible with standard supervisor applications.

Q: What is the difference between DS1706EPA and DS1706EPA+? A: Both parts are parametric equivalents with identical electrical specifications and reset timing. The primary difference is RoHS compliance: DS1706EPA+ meets ROHS3 standards while DS1706EPA does not. Both are classified as obsolete.

Q: Why is the ADM706ANZ recommended over DS1706EPA+? A: The ADM706ANZ carries active product status, ensuring ongoing manufacturing and supply availability. DS1706EPA+ remains obsolete. For new designs and long-term system support, the active status of ADM706ANZ provides superior supply chain reliability.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout for single-channel supervisor applications.

Q: Does the 160ms reset timeout of ADM706ANZ affect compatibility? A: No. The extended reset timeout is compatible with standard power management and reset sequencing applications. The 160ms minimum exceeds the 130ms specification of the original part, providing additional timing margin.

Q: What compliance certifications apply to these parts? A: DS1706EPA is RoHS non-compliant. Both DS1706EPA+ and ADM706ANZ meet ROHS3 compliance. All three parts are REACH unaffected and carry EAR99 ECCN classification.
