DS1706TESA Equivalent & Substitute Parts

Part Overview

The DS1706TESA is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single-channel reset/power-on reset supervisor with push-pull, totem pole output configuration. The device is classified as obsolete, which necessitates identification of functionally equivalent active alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage monitoring, reset logic, and output characteristics while meeting current manufacturing and compliance standards.

Engineering Selection Recommendations

For Active Production and New Designs:

DS1706TESA+ is the direct successor variant from the original manufacturer. It maintains identical electrical specifications while achieving ROHS3 compliance and active product status. This part is recommended as the primary replacement for the obsolete DS1706TESA.

ADM706TARZ and ADM706TARZ-REEL are manufacturer-recommended alternatives from Analog Devices Inc. Both parts provide equivalent functionality with ROHS3 compliance and active status. ADM706TARZ-REEL offers higher inventory availability (20100 Pcs) and tape & reel packaging suitable for automated assembly processes.

For High-Volume Manufacturing:

SP706TEN-L/TR from MaxLinear, Inc. provides the highest inventory availability (55400 Pcs) among all qualified substitutes. This part maintains all critical electrical parameters and offers RoHS compliance with tape & reel packaging optimized for production environments.

STM706TM6F from STMicroelectronics is an alternative source option with substantial inventory (4435 Pcs) and ROHS3 compliance. This part provides supply chain diversification benefits.

For Specific Packaging Requirements:

MIC706TMY-TR from Microchip Technology is available in tape & reel format with 3200 Pcs inventory. This option provides an alternative manufacturer source with active product status and ROHS3 compliance.

Compliance Considerations:

All substitute parts except SP706TEN-L/TR achieve ROHS3 compliance. SP706TEN-L/TR meets RoHS compliance standards. The original DS1706TESA is RoHS non-compliant; migration to any substitute part improves regulatory compliance posture for new designs.

Frequently Asked Questions (FAQ)

Q: Can DS1706TESA be directly replaced with DS1706TESA+ without circuit modification?

A: Yes. DS1706TESA+ maintains identical electrical specifications including voltage threshold (3.08V), reset timeout (130ms minimum), output configuration (push-pull, totem pole), and package form factor (8-SOIC). The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit redesign is required.

Q: What is the difference between reset timeout specifications of 130ms, 140ms, and 160ms?

A: Reset timeout defines the minimum duration the reset output remains asserted after power supply stabilization. DS1706TESA specifies 130ms minimum. Substitute parts with 140ms or 160ms minimum timeouts provide equal or longer reset assertion periods. This variation is acceptable because longer reset timeouts do not compromise system functionality; they provide additional margin for power supply settling and initialization sequencing.

Q: Are MIC706TMY and MIC706TMY-TR electrically identical?

A: Yes. Both parts are identical Microchip Technology MIC706 supervisors with 3.08V threshold and 140ms minimum reset timeout. The difference is packaging format: MIC706TMY is supplied in Tube packaging, while MIC706TMY-TR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why do some substitute parts not specify output configuration?

A: MIC706TMY, MIC706TMY-TR, and SP706TEN-L/TR do not explicitly specify output configuration in the provided data. However, these parts are functionally equivalent single-channel supervisors with identical voltage thresholds and reset logic. Output configuration compatibility is established through functional equivalence and manufacturer cross-reference documentation.

Q: Is SP706TEN-L/TR suitable for applications requiring -40°C to 85°C operation?

A: Yes. SP706TEN-L/TR operates across the -40°C to 85°C temperature range, matching the DS1706TESA specification. This part is suitable for industrial and extended-temperature applications.

Q: What packaging format should be selected for automated assembly?

A: For automated pick-and-place assembly, tape & reel packaging (TR) is standard. ADM706TARZ-REEL, MIC706TMY-TR, and SP706TEN-L/TR are all available in tape & reel format. STM706TM6F is available in Cut Tape (CT) & Digi-Reel® format, which is also suitable for automated assembly. Tube packaging (DS1706TESA+, ADM706TARZ, MIC706TMY) is typically used for manual assembly or lower-volume applications.

Q: Are all substitute parts RoHS compliant?

A: Seven of eight substitute parts achieve ROHS3 compliance: DS1706TESA+, STM706TM6F, ADM706TARZ, ADM706TARZ-REEL, MIC706TMY, and MIC706TMY-TR. SP706TEN-L/TR meets RoHS compliance standards. The original DS1706TESA is RoHS non-compliant. For applications subject to RoHS regulations, any substitute part improves compliance status.

Q: Which substitute part offers the best inventory availability?

A: SP706TEN-L/TR from MaxLinear, Inc. provides the highest inventory availability at 55400 Pcs. ADM706TARZ-REEL is the second-highest option at 20100 Pcs. Both parts are suitable for high-volume production requirements.
