DS1706RESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1706RESA/T&R is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. This single-channel supervisor operates as a push-pull, totem pole reset circuit with a 2.63V threshold voltage and 130ms minimum reset timeout. The device is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute parts maintain the core supervisory function while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1706RESA/T&R is determined by the following critical parameters:

• Voltage Threshold: 2.63V (all substitutes maintain this specification)
• Output Configuration: Push-Pull, Totem Pole topology
• Reset Logic: Active Low
• Package: 8-SOIC form factor
• Mounting: Surface Mount
• Temperature Range: -40°C ~ 85°C (primary requirement; SP706RCN-L/TR operates 0°C ~ 70°C and is restricted)
• Reset Timeout: Minimum 130ms (substitutes provide 140ms or 160ms, exceeding requirement)

Substitute parts are grouped into two categories:

Category A - Direct Analog Devices Equivalents: DS1706RESA+T&R, ADM706RARZ, ADM706RARZ-REEL, ADM706RARZ-REEL7. These maintain identical electrical specifications with improved product status and RoHS3 compliance.

Category B - Cross-Manufacturer Alternatives: SP706REN-L/TR and SP706RCN-L/TR from MaxLinear, Inc. These provide equivalent functionality with identical threshold voltage, reset logic, and package, though SP706RCN-L/TR has a restricted temperature range (0°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DS1706RESA+T&R is the direct functional equivalent with identical electrical specifications, active product status, and RoHS3 compliance. This part provides the most direct replacement path with no design modifications required.

Secondary Recommendations: ADM706RARZ, ADM706RARZ-REEL, and ADM706RARZ-REEL7 are functionally equivalent Analog Devices alternatives. These parts maintain the 2.63V threshold, active-low reset, and full temperature range (-40°C ~ 85°C). The extended reset timeout (160ms vs. 130ms) exceeds the original specification and poses no compatibility risk. Packaging variants (Tube, Cut Tape & Digi-Reel, standard Digi-Reel) accommodate different procurement and assembly workflows.

Cross-Manufacturer Alternative: SP706REN-L/TR from MaxLinear, Inc. provides equivalent supervisory function with identical threshold voltage, active-low reset logic, and full temperature range support. This option is suitable for applications where multi-source qualification is required.

Restricted Use: SP706RCN-L/TR operates within a narrower temperature range (0°C ~ 70°C) and is suitable only for applications that do not require the full -40°C ~ 85°C operating envelope of the original part.

Frequently Asked Questions (FAQ)

Q: Can DS1706RESA+T&R be used as a direct replacement for DS1706RESA/T&R?

A: Yes. DS1706RESA+T&R is electrically and mechanically identical to the obsolete DS1706RESA/T&R, with the addition of active product status and RoHS3 compliance. No circuit modifications are required.

Q: What is the difference between ADM706RARZ, ADM706RARZ-REEL, and ADM706RARZ-REEL7?

A: These parts are electrically identical. The differences are packaging and delivery format: ADM706RARZ is supplied in Tube packaging, ADM706RARZ-REEL in Cut Tape & Digi-Reel format, and ADM706RARZ-REEL7 in standard Digi-Reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Why does ADM706RARZ have a 160ms reset timeout instead of 130ms?

A: The extended reset timeout (160ms) exceeds the original 130ms specification and remains functionally compatible. The longer timeout provides additional margin for power supply stabilization and does not compromise circuit operation.

Q: Can SP706RCN-L/TR be used in applications requiring -40°C operation?

A: No. SP706RCN-L/TR operates only within 0°C ~ 70°C and cannot be used in applications requiring the full -40°C ~ 85°C temperature range. SP706REN-L/TR supports the extended temperature range and is the appropriate MaxLinear alternative for such applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (DS1706RESA+T&R, ADM706RARZ variants, and SP706 series) are RoHS compliant. The original DS1706RESA/T&R is RoHS non-compliant, making compliance upgrade a benefit of substitution.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package is a standard surface-mount form factor. All substitute parts maintain this identical package geometry, ensuring direct PCB compatibility without layout modifications.
