DS1708SESA Equivalent & Substitute Parts

Part Overview

The DS1708SESA is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. This device functions as a single-channel reset/power-on reset supervisor with push-pull output configuration, designed for monitoring power supply voltages in electronic systems. The DS1708SESA is classified as obsolete, which necessitates identification of functionally equivalent substitute components for new designs and ongoing production requirements. Equivalent parts maintain the same electrical characteristics, package form factor, and operational parameters while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1708SESA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Voltage - Threshold: 2.93V
• Number of Voltages Monitored: 1
• Type: Simple Reset/Power-On Reset
• Reset: Active High/Active Low
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount

Allowable Variations:

• Output Configuration: Push-Pull, Complementary, or Totem Pole outputs are functionally compatible for reset supervision applications
• Reset Timeout: Minimum values between 130ms and 160ms are acceptable within the supervisor tolerance band
• Product Status: Active status preferred over obsolete
• RoHS Compliance: ROHS3 compliant versions are preferred for new designs
• Packaging Format: Tube, Cut Tape & Digi-Reel, or Tape & Reel formats are interchangeable based on procurement requirements

Substitute parts must maintain identical electrical thresholds, monitoring capability, and thermal operating range to ensure direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DS1708SESA+

The DS1708SESA+ is the direct successor to the DS1708SESA, manufactured by the same supplier (Analog Devices Inc./Maxim Integrated). This part maintains identical electrical specifications, output configuration, and package form factor. The DS1708SESA+ offers active product status and ROHS3 compliance, making it the preferred choice for design continuity and regulatory compliance. Inventory availability is substantial at 12,300 pieces.

Secondary Recommendations: ADM708SARZ and ADM708SARZ-REEL

The ADM708SARZ and ADM708SARZ-REEL are manufacturer-recommended alternatives from Analog Devices Inc. Both parts maintain the 2.93V threshold, push-pull output, and 8-SOIC package. The reset timeout specification is 160ms minimum, which exceeds the DS1708SESA minimum of 130ms but remains within acceptable supervisor tolerance bands. Both variants offer ROHS3 compliance and active product status. The ADM708SARZ-REEL variant provides the highest inventory availability at 25,200 pieces and is packaged in Cut Tape & Digi-Reel format for high-volume production.

Tertiary Recommendations: MIC708SMY and MIC708SMY-TR

The MIC708SMY and MIC708SMY-TR are Microchip Technology equivalents with complementary output configuration instead of push-pull. These parts maintain the 2.93V threshold, single-channel monitoring, and 8-SOIC package. The reset timeout is 140ms minimum. Complementary output topology is functionally compatible with push-pull applications in reset supervision circuits. Both variants offer ROHS3 compliance and active product status. The MIC708SMY-TR variant is available in Tape & Reel format with 2,749 pieces in inventory.

Alternative Recommendation: STM708SM6F

The STM708SM6F is manufactured by STMicroelectronics and features push-pull/totem pole output configuration. This part maintains the 2.93V threshold, single-channel monitoring, and 8-SOIC package. The reset timeout is 140ms minimum. The STM708SM6F offers ROHS3 compliance and active product status with 5,303 pieces in inventory, packaged in Tape & Reel format.

Alternative Recommendation: SP708SEN-L/TR

The SP708SEN-L/TR is manufactured by MaxLinear, Inc. and maintains the 2.93V threshold, single-channel monitoring, and 8-SOIC package. The reset timeout is 140ms minimum. This part offers RoHS compliance and active product status with the highest inventory availability at 25,300 pieces, packaged in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can I use DS1708SESA+ as a direct replacement for DS1708SESA?

A: Yes. The DS1708SESA+ is electrically and mechanically identical to the DS1708SESA. Both parts share the same 2.93V threshold, push-pull output, 130ms reset timeout, and 8-SOIC package. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

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

A: Push-pull output uses a single output stage that actively drives both high and low logic states. Complementary output provides both true and inverted signal outputs simultaneously. For reset supervision applications, both configurations are functionally compatible as they provide the required active high/active low reset signaling. Circuit design must account for the available output signals.

Q: Are the ADM708SARZ variants suitable replacements despite the 160ms reset timeout versus 130ms?

A: Yes. The ADM708SARZ and ADM708SARZ-REEL maintain the same voltage threshold (2.93V), monitoring capability, and package form factor. The reset timeout difference (160ms vs. 130ms) represents a longer power-on reset delay, which is acceptable in supervisor applications. The extended timeout does not compromise functionality and may provide additional system stabilization time.

Q: What packaging formats are available for these substitute parts?

A: Substitute parts are available in three packaging formats: Tube (standard packaging for lower-volume applications), Cut Tape & Digi-Reel (for moderate-volume production), and Tape & Reel (for high-volume automated assembly). Selection depends on production volume and assembly equipment compatibility. All formats contain identical components in the same 8-SOIC package.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are RoHS compliant (ROHS3 or RoHS). The original DS1708SESA is RoHS non-compliant. For new designs and applications subject to RoHS regulations, any of the listed substitute parts satisfy compliance requirements.

Q: Can I mix different substitute parts in the same production run?

A: Yes, provided the circuit design accommodates the specific output configuration of each part. DS1708SESA+, ADM708SARZ variants, and STM708SM6F all feature push-pull output and are directly interchangeable. MIC708SMY variants feature complementary output and require circuit design verification. SP708SEN-L/TR output configuration is not specified and requires datasheet verification before use.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All listed parts, including the original DS1708SESA, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
