DS1707ESA Equivalent & Substitute Parts

Part Overview

The DS1707ESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management PMIC. This device functions as a simple reset/power-on reset supervisor with push-pull output configuration, monitoring a single voltage channel at a 4.65V threshold. The DS1707ESA is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement. Substitute parts maintain functional equivalence through matching electrical parameters and identical 8-SOIC surface mount packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1707ESA are qualified based on the following critical parameters:

• Voltage Threshold: 4.65V ±0.02V tolerance
• Number of Voltages Monitored: Single channel
• Output Type: Push-Pull configuration
• Reset Logic: Active High/Active Low capability
• Package: 8-SOIC form factor
• Operating Temperature: -40°C ~ 85°C range
• Mounting: Surface mount technology

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications designed for the DS1707ESA. Variations in reset timeout (130ms to 160ms) and minor voltage threshold deviations (4.63V to 4.65V) remain within acceptable substitution parameters for supervisor circuit applications.

Parameter Comparison

Engineering Selection Recommendations

DS1707ESA+ (Direct Upgrade) The DS1707ESA+ is the direct successor from the same manufacturer, maintaining identical electrical specifications while offering active product status and ROHS3 compliance. This part is the primary recommendation for designs currently using the obsolete DS1707ESA.

ADM707ARZ and ADM707ARZ-REEL (Manufacturer Recommended) Both ADM707 variants from Analog Devices Inc. are manufacturer-recommended substitutes. These parts maintain the 4.65V threshold and single-channel monitoring architecture. The ADM707ARZ-REEL variant provides cut tape and Digi-Reel packaging for high-volume applications. Reset timeout extends to 160ms minimum, which remains compatible with supervisor circuit timing requirements.

SP707EN-L/TR (Cross-Manufacturer Alternative) The SP707EN-L/TR from MaxLinear, Inc. provides functional equivalence with 4.65V threshold and 140ms reset timeout. This part is suitable for applications where multi-source component availability is required.

STM707M6F (Cross-Manufacturer Alternative) The STM707M6F from STMicroelectronics maintains the 4.65V threshold specification with 140ms reset timeout. The voltage threshold of 4.63V represents a 0.02V deviation from the DS1707ESA, remaining within acceptable supervisor circuit tolerances. This part offers ROHS3 compliance and active product status.

All substitute parts maintain surface mount 8-SOIC packaging and -40°C to 85°C operating temperature range, ensuring mechanical and thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the DS1707ESA+ be used as a direct replacement for the DS1707ESA? A: Yes. The DS1707ESA+ maintains identical electrical specifications including 4.65V threshold, 130ms reset timeout, and push-pull output configuration. The primary difference is product status (active versus obsolete) and improved RoHS3 compliance.

Q: What is the significance of the reset timeout differences between substitute parts? A: Reset timeout values range from 130ms to 160ms across the substitute parts. These variations represent different internal timing circuit designs but remain functionally compatible for supervisor applications. The application circuit design should verify that the specific reset timeout meets system requirements.

Q: Are all substitute parts available in 8-SOIC packaging? A: Yes. All listed substitute parts are available in 8-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring mechanical compatibility with existing PCB designs.

Q: What is the difference between ADM707ARZ and ADM707ARZ-REEL? A: Both parts are electrically identical. The primary difference is packaging format: ADM707ARZ is supplied in tube packaging, while ADM707ARZ-REEL is supplied in cut tape and Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Does the 4.63V threshold of the STM707M6F affect compatibility? A: The STM707M6F voltage threshold of 4.63V represents a 0.02V deviation from the DS1707ESA specification of 4.65V. This minor difference remains within acceptable tolerances for supervisor circuit applications and does not affect functional compatibility.

Q: Are all substitute parts RoHS compliant? A: Yes. All active substitute parts listed (DS1707ESA+, ADM707ARZ, ADM707ARZ-REEL, SP707EN-L/TR, and STM707M6F) are RoHS compliant, meeting current environmental and regulatory requirements.

Q: Can cross-manufacturer parts (SP707EN-L/TR, STM707M6F) be used interchangeably with Analog Devices parts? A: Yes. All substitute parts maintain the critical electrical parameters (single-channel monitoring, 4.65V threshold, push-pull output, active high/active low reset logic) and identical 8-SOIC packaging. Cross-manufacturer substitution is supported for applications requiring multi-source component availability.
