DS1708TESA Equivalent & Substitute Parts

Part Overview

The DS1708TESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. This single-channel supervisor operates with a 3.08V threshold voltage and provides push-pull output configuration in an 8-SOIC package. The device is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. Active substitute parts maintain the same electrical specifications and mechanical compatibility while offering current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1708TESA is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Voltage threshold: 3.08V (exact match required)
• Number of voltages monitored: 1 channel
• Package type: 8-SOIC form factor with 0.154" width (3.90mm)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C minimum
• Reset logic capability: Active High/Active Low support
• Reset timeout: 130ms minimum or greater

Secondary Compatibility Factors:

• Output configuration: Push-Pull, Complementary, or Totem Pole outputs are functionally compatible in supervisor applications
• Reset timeout variance: Substitute parts with 140ms, 160ms, or greater timeouts maintain functional compatibility
• Product status: Active parts are preferred over obsolete designations
• Compliance certifications: RoHS3 compliance and REACH unaffected status indicate modern manufacturing standards

Substitute parts from Analog Devices, Microchip Technology, MaxLinear, and STMicroelectronics meet these criteria while offering improved availability and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): DS1708TESA+ is the primary substitute, offering identical electrical specifications and mechanical compatibility with improved product status (Active) and RoHS3 compliance. This part maintains the original push-pull output configuration and 130ms reset timeout.

Analog Devices Alternatives: ADM708TARZ and ADM708TARZ-REEL provide functionally equivalent supervision with extended 160ms reset timeout. Both parts maintain push-pull output and are available in active product status with RoHS3 compliance. The REEL variant offers cut tape and Digi-Reel packaging for automated assembly environments.

Multi-Source Alternatives: MIC708TMY and MIC708TMY-TR (Microchip Technology) offer complementary output configuration with 140ms reset timeout. STM708TM6F (STMicroelectronics) provides push-pull and totem pole output options with 140ms timeout. SP708TEN-L/TR (MaxLinear) maintains the 3.08V threshold with 140ms timeout. All alternatives are active products with current compliance certifications.

Compliance Considerations: All substitute parts listed carry RoHS3 compliance or RoHS compliance status, addressing the non-compliant status of the original DS1708TESA. REACH unaffected status is maintained across Analog Devices and STMicroelectronics alternatives.

Frequently Asked Questions (FAQ)

Q: Can DS1708TESA+ be used as a direct replacement for DS1708TESA? A: Yes. DS1708TESA+ maintains identical voltage threshold (3.08V), output configuration (push-pull), reset timeout (130ms minimum), and 8-SOIC package specifications. The primary differences are active product status and RoHS3 compliance.

Q: What is the functional difference between push-pull and complementary output configurations? A: Push-pull output (DS1708TESA, ADM708TARZ) provides active high and active low drive capability. Complementary output (MIC708TMY) provides inverted signal pairs. Both configurations support active high/active low reset logic and are functionally compatible in supervisor applications with appropriate circuit design.

Q: Does the increased reset timeout in ADM708TARZ affect circuit operation? A: ADM708TARZ specifies 160ms minimum reset timeout compared to 130ms for DS1708TESA. This extended timeout provides additional power supply stabilization time and is functionally compatible with designs tolerating longer reset assertion periods. Verify circuit timing requirements before selection.

Q: Are packaging variants (tube, cut tape, tape & reel) electrically equivalent? A: Yes. Packaging variants (DS1708TESA+ in tube, ADM708TARZ-REEL in cut tape/Digi-Reel, MIC708TMY-TR in tape & reel) contain identical die and electrical specifications. Packaging selection depends on assembly process requirements and quantity handling.

Q: What compliance advantage do substitute parts offer? A: All substitute parts carry RoHS3 compliance or RoHS compliance status, addressing environmental and regulatory requirements. The original DS1708TESA is RoHS non-compliant. REACH unaffected status is maintained across Analog Devices and STMicroelectronics alternatives.

Q: Can multiple substitute parts be used interchangeably in production? A: Yes, provided circuit design accommodates output configuration differences (push-pull vs. complementary) and reset timeout variations (130ms to 160ms). Verify PCB layout compatibility with 8-SOIC package specifications and confirm signal timing requirements with extended timeouts.
