DS1708SESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1708SESA/T&R is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and simple reset applications in embedded systems. This component monitors a single voltage threshold at 2.93V and provides push-pull output control with active high/active low reset capability. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1708SESA/T&R is determined by the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and electrical compatibility
• Voltage - Threshold: 2.93V — functional equivalence for power supply monitoring
• Number of Voltages Monitored: 1 — single-channel supervision requirement
• Operating Temperature: -40°C ~ 85°C (TA) — thermal operating range
• Type: Simple Reset/Power-On Reset — functional classification
• Reset: Active High/Active Low — control logic compatibility
• Mounting Type: Surface Mount — assembly compatibility

All substitute parts listed maintain these core parameters. Variations in output type (Push-Pull vs. Complementary), reset timeout specifications, and packaging format (Tube, Tape & Reel, Cut Tape & Digi-Reel) do not prevent functional substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

DS1708SESA+T&R is the direct equivalent of the obsolete DS1708SESA/T&R, maintaining identical electrical specifications and packaging format while offering active product status and ROHS3 compliance. This part is the primary recommendation for direct replacement in new designs and production continuations.

ADM708SARZ and ADM708SARZ-REEL are manufacturer-recommended alternatives from Analog Devices Inc., offering active product status and ROHS3 compliance. These parts maintain all critical parameters with a slightly extended reset timeout of 160ms minimum compared to the original 130ms minimum specification. Packaging options include Tube (ADM708SARZ) and Cut Tape & Digi-Reel (ADM708SARZ-REEL) formats.

MIC708SMY and MIC708SMY-TR are Microchip Technology equivalents with active product status and ROHS3 compliance. These parts feature complementary output configuration rather than push-pull, with a 140ms minimum reset timeout. Packaging options include Tube (MIC708SMY) and Tape & Reel (MIC708SMY-TR) formats.

SP708SEN-L/TR is a MaxLinear, Inc. alternative with active product status and RoHS compliance, offered in Tape & Reel packaging with a 140ms minimum reset timeout. Output type is not specified in available documentation.

All substitute parts maintain the 8-SOIC package footprint, 2.93V threshold voltage, single-channel monitoring, and -40°C to 85°C operating temperature range required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can DS1708SESA+T&R be used as a direct replacement for DS1708SESA/T&R?

A: Yes. DS1708SESA+T&R is electrically and mechanically identical to the obsolete DS1708SESA/T&R, with the primary differences being active product status and ROHS3 compliance. Pin configuration, voltage threshold, output type, and package dimensions are unchanged.

Q: What is the difference between push-pull and complementary output configurations?

A: Push-pull output provides two independent output stages capable of sourcing and sinking current. Complementary output provides one output stage with complementary logic levels. Both configurations are functionally compatible for reset supervision applications when the circuit design accommodates the output type.

Q: Are there packaging format differences between substitute parts?

A: Yes. Substitute parts are available in Tube, Tape & Reel (TR), and Cut Tape & Digi-Reel (CT) formats. All formats contain the same die and electrical specifications. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Does the reset timeout variation between parts affect substitution?

A: Reset timeout variations (130ms, 140ms, 160ms minimum) represent different timing specifications for the same functional operation. Selection depends on system requirements for power-on reset delay. All values fall within the same functional category and do not prevent substitution when timing requirements are met.

Q: Are all substitute parts RoHS compliant?

A: The original DS1708SESA/T&R is RoHS non-compliant. All active substitute parts listed (DS1708SESA+T&R, ADM708SARZ, ADM708SARZ-REEL, MIC708SMY, MIC708SMY-TR, SP708SEN-L/TR) are RoHS3 or RoHS compliant, making them suitable for applications requiring environmental compliance.

Q: Can parts from different manufacturers be mixed in the same production run?

A: Yes. All substitute parts maintain identical package footprints (8-SOIC), voltage thresholds (2.93V), and functional specifications. Parts from Analog Devices Inc., Microchip Technology, and MaxLinear, Inc. are mechanically and electrically interchangeable when output type requirements are met.
