DS1706SESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1706SESA/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. This MicroMonitor™ series device operates as a push-pull, totem pole output supervisor with a 2.93V threshold voltage and 130ms minimum reset timeout. The part is currently classified as obsolete, necessitating identification of functionally equivalent active alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1706SESA/T&R is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Voltage - Threshold: 2.93V
• Number of Voltages Monitored: 1
• Reset: Active Low
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Reset Timeout: Minimum 130ms

Acceptable Variation:

• Reset Timeout values of 140ms minimum are acceptable as they exceed the 130ms minimum requirement
• Output configuration (Push-Pull, Totem Pole vs. unspecified) does not preclude substitution when all other parameters align
• Packaging format (Tape & Reel vs. standard packaging) represents a logistics variation, not a functional difference

Four active substitute parts meet these criteria across manufacturers Microchip Technology, MaxLinear, Inc., and Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

DS1706SESA+T&R (Analog Devices Inc./Maxim Integrated) Direct successor from the original manufacturer. Identical electrical specifications and package. Upgraded to ROHS3 compliance. Recommended for designs requiring continuity with the original MicroMonitor™ series platform.

MIC706SMY-TR (Microchip Technology) Active alternative with 140ms reset timeout, exceeding the 130ms minimum requirement. ROHS3 compliant. Available in Tape & Reel packaging. Suitable for new designs prioritizing multi-source component availability.

SP706SEN-L/TR (MaxLinear, Inc.) Active alternative with 140ms reset timeout. RoHS compliant. Highest inventory availability (55,300 pcs). Suitable for high-volume production requiring extended lead-time protection.

TPS3705-33DR (Texas Instruments) Active alternative with push-pull, totem pole output matching the original part specification. 140ms reset timeout. ROHS3 compliant. Recommended for designs requiring output stage compatibility with the original DS1706SESA/T&R topology.

Frequently Asked Questions (FAQ)

Q: Can I use MIC706SMY-TR as a direct replacement for DS1706SESA/T&R? A: Yes. Both parts share identical voltage threshold (2.93V), single-channel monitoring, active-low reset, 8-SOIC package, and -40°C to 85°C operating range. The MIC706SMY-TR reset timeout of 140ms exceeds the 130ms minimum requirement, maintaining functional compatibility.

Q: What is the difference between DS1706SESA/T&R and DS1706SESA+T&R? A: Both parts are electrically identical with matching specifications. The primary difference is product status: DS1706SESA/T&R is obsolete, while DS1706SESA+T&R is active. DS1706SESA+T&R also carries ROHS3 compliance versus RoHS non-compliance of the original part.

Q: Does the 140ms reset timeout on substitute parts affect circuit operation? A: No. The 140ms timeout on MIC706SMY-TR, SP706SEN-L/TR, and TPS3705-33DR exceeds the 130ms minimum specification of the original part. Longer reset timeouts provide additional margin and do not compromise functionality in applications designed for the original 130ms specification.

Q: Are all substitute parts available in the same packaging format? A: All substitute parts are available in 8-SOIC surface-mount packages. Packaging variations (Tape & Reel vs. Tube) represent logistics options, not functional differences. Verify packaging format with your supplier based on assembly requirements.

Q: Which substitute part should I select for new production designs? A: Selection depends on design priorities. For manufacturer continuity, choose DS1706SESA+T&R. For multi-source availability, choose MIC706SMY-TR or SP706SEN-L/TR. For output stage topology matching, choose TPS3705-33DR. All four parts meet the electrical and mechanical requirements of the original DS1706SESA/T&R.

Q: Are all substitute parts RoHS compliant? A: Yes. DS1706SESA+T&R, MIC706SMY-TR, SP706SEN-L/TR, and TPS3705-33DR are all RoHS compliant (ROHS3 or RoHS), whereas the original DS1706SESA/T&R is RoHS non-compliant. This represents an improvement for regulatory compliance in new designs.
