DS1707ESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1707ESA/T&R is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for reset and power-on reset applications in power management circuits. This component operates as a push-pull output supervisor with a 4.65V threshold and 130ms minimum reset timeout. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1707ESA/T&R is determined by the following critical parameters:

• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width) — mechanical compatibility requirement
• Voltage - Threshold: 4.65V — functional threshold specification
• Number of Voltages Monitored: 1 channel — functional requirement
• Type: Simple Reset/Power-On Reset — functional classification
• Reset Output: Push-Pull configuration — output stage compatibility
• Reset Logic: Active High/Active Low — logic level compatibility
• Operating Temperature Range: -40°C ~ 85°C (TA) — thermal operating envelope
• Reset Timeout: Minimum 130ms — timing specification tolerance

Substitute parts must match or exceed these parameters. Variations in reset timeout (160ms vs. 130ms) and packaging format (Tape & Reel vs. Cut Tape) do not affect functional equivalence when the core electrical specifications align.

Parameter Comparison

Engineering Selection Recommendations

DS1707ESA+T&R — Direct equivalent with identical electrical specifications and same-series MicroMonitor™ designation. Offers active product status and ROHS3 compliance. Packaging format differs (Tape & Reel vs. standard packaging) but does not affect functional performance. Recommended for direct replacement in new designs and production restocking.

ADM707ARZ and ADM707ARZ-REEL — Functionally equivalent alternatives from Analog Devices Inc. with active product status and ROHS3 compliance. Reset timeout specification of 160ms exceeds the 130ms minimum requirement, providing additional timing margin. Available in both tube and cut tape/Digi-Reel® packaging formats. Suitable for applications where extended reset timing is acceptable.

SP707EN-L/TR — Cross-manufacturer equivalent from MaxLinear, Inc. with active product status and RoHS compliance. Maintains all critical electrical parameters including 4.65V threshold, single-channel monitoring, and active high/active low reset logic. Reset timeout of 140ms meets specification requirements. Output configuration not specified in documentation. Recommended where multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can DS1707ESA+T&R directly replace DS1707ESA/T&R in existing assemblies?

A: Yes. Both parts share identical electrical specifications, threshold voltage, reset timeout, and operating temperature range. The primary difference is product status (active vs. obsolete) and RoHS compliance certification. Packaging format differences do not affect circuit performance.

Q: What is the significance of the 160ms reset timeout in ADM707ARZ variants compared to the 130ms specification?

A: The ADM707ARZ series provides a longer minimum reset timeout (160ms vs. 130ms), which exceeds the original specification. This extended timing is functionally compatible and provides additional margin for power supply stabilization. Applications requiring the exact 130ms timing should verify compatibility with system requirements.

Q: Are ADM707ARZ and ADM707ARZ-REEL electrically identical?

A: Yes. Both parts are electrically identical. The difference is packaging format: ADM707ARZ is supplied in tube packaging, while ADM707ARZ-REEL uses cut tape with Digi-Reel® format. Selection depends on assembly equipment and inventory management requirements.

Q: Is SP707EN-L/TR suitable for applications currently using DS1707ESA/T&R?

A: SP707EN-L/TR is functionally equivalent for core supervisor functions. All critical parameters including threshold voltage, channel count, reset logic, and operating temperature align with the original specification. The part is from a different manufacturer (MaxLinear vs. Analog Devices), which may require qualification in regulated environments.

Q: What compliance certifications should be considered when selecting a substitute?

A: The original DS1707ESA/T&R is RoHS non-compliant. All recommended substitutes (DS1707ESA+T&R, ADM707ARZ, ADM707ARZ-REEL, SP707EN-L/TR) meet current RoHS or ROHS3 compliance standards. For applications subject to environmental regulations, any of these alternatives satisfy compliance requirements.

Q: Does the 8-SOIC package remain consistent across all substitute options?

A: Yes. All substitute parts maintain the 8-SOIC (0.154", 3.90mm Width) package specification, ensuring mechanical compatibility with existing PCB layouts and assembly processes.
