DS1706SESA Equivalent & Substitute Parts

Part Overview

The DS1706SESA is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and simple reset applications. This device operates as a push-pull, totem pole output supervisor with a 2.93V threshold voltage and 130ms minimum reset timeout. The DS1706SESA is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence across voltage monitoring, reset behavior, output topology, and package specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1706SESA are selected based on strict electrical and mechanical parameter alignment. The critical substitution criteria are:

• Single-channel voltage monitoring capability
• 2.93V threshold voltage
• Active-low reset output
• Push-pull, totem pole output topology
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Operating temperature range of -40°C to 85°C
• Reset timeout minimum of 130ms or greater
• Moisture sensitivity level MSL 1

All identified substitute parts meet these core requirements. Variations in product status (active vs. obsolete), RoHS compliance, and packaging format (tube, tape & reel, cut tape) do not affect functional equivalence but may influence procurement and environmental compliance considerations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain functional equivalence to the DS1706SESA across core electrical parameters: single-channel voltage monitoring, 2.93V threshold, active-low reset, and 8-SOIC package compatibility.

DS1706SESA+ is the direct successor from Analog Devices Inc./Maxim Integrated, offering identical electrical specifications with active product status and ROHS3 compliance. This part is the primary recommendation for direct replacement in new designs.

STM706SM6F (STMicroelectronics), MIC706SMY and MIC706SMY-TR (Microchip Technology), SP706SEN-L/TR (MaxLinear, Inc.), and TPS3705-33D (Texas Instruments) are functionally equivalent alternatives with active product status and RoHS compliance. These parts feature reset timeout specifications of 140ms minimum, which exceeds the DS1706SESA requirement of 130ms minimum.

For applications requiring RoHS compliance, all substitute parts except the original DS1706SESA meet ROHS3 or equivalent standards. Packaging format variations (tube, tape & reel, cut tape) accommodate different procurement and assembly workflows without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can DS1706SESA+ be used as a direct replacement for DS1706SESA?

A: Yes. DS1706SESA+ maintains identical electrical specifications including 2.93V threshold voltage, 130ms reset timeout, push-pull totem pole output, and 8-SOIC package. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the significance of the 130ms vs. 140ms reset timeout difference?

A: The DS1706SESA specifies 130ms minimum reset timeout, while most substitute parts specify 140ms minimum. A longer reset timeout does not compromise functionality; it provides additional margin for power supply stabilization. Applications designed for 130ms operation remain compatible with 140ms timeout parts.

Q: Are MIC706SMY and MIC706SMY-TR electrically identical?

A: Yes. Both parts are identical Microchip Technology MIC706 supervisors with 2.93V threshold and active-low reset. The difference is packaging format: MIC706SMY is supplied in tube packaging, while MIC706SMY-TR is supplied in tape & reel format. Electrical performance and pin configuration are identical.

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

A: Yes. All substitute parts use 8-SOIC surface mount packaging with 0.154" width (3.90mm). PCB footprints and reflow soldering profiles are compatible across all listed parts.

Q: What is the impact of RoHS compliance on part selection?

A: The original DS1706SESA is RoHS non-compliant. All substitute parts are RoHS compliant (ROHS3 or equivalent). For applications subject to RoHS regulations or customer requirements, substitute parts are mandatory. For legacy systems without RoHS requirements, both compliant and non-compliant parts function identically.

Q: Can parts with unspecified output topology be used in place of push-pull totem pole designs?

A: MIC706SMY, MIC706SMY-TR, and SP706SEN-L/TR do not specify output topology in the provided data. For applications requiring confirmed push-pull totem pole output, DS1706SESA+, STM706SM6F, and TPS3705-33D are recommended. Consult manufacturer datasheets for MIC706 and SP706 output specifications if totem pole topology is critical.

Q: What inventory considerations apply to these substitute parts?

A: DS1706SESA+ (1,320 pcs), STM706SM6F (20,400 pcs), MIC706SMY (1,560 pcs), MIC706SMY-TR (5,250 pcs), SP706SEN-L/TR (55,300 pcs), and TPS3705-33D (3,800 pcs) are available in stock. SP706SEN-L/TR offers the highest inventory availability.
