DS1708RESA+ Equivalent & Substitute Parts

Part Overview

The DS1708RESA+ is an active supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for power management and reset signal generation in electronic systems. This single-channel supervisor operates with a 2.63V threshold voltage and provides push-pull output configuration. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, package compatibility, and operational parameters align with the original specification, enabling component sourcing flexibility without redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1708RESA+ is determined by strict alignment of the following critical parameters:

• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width) for direct PCB compatibility
• Number of Voltages Monitored: Single channel configuration
• Voltage - Threshold: 2.63V nominal threshold
• Output Configuration: Push-Pull topology
• Reset Type: Active High/Active Low capability
• Operating Temperature Range: -40°C ~ 85°C minimum coverage
• Mounting Type: Surface Mount technology
• RoHS Status: ROHS3 Compliant certification

Substitute parts must satisfy all parameters listed above. Minor variations in reset timeout (130ms to 160ms) and secondary output descriptions (Push-Pull vs. Totem Pole) are permissible when all primary electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compliance equivalent to the DS1708RESA+. The ADM708RARZ and ADM708RARZ-REEL variants differ only in packaging format (Tube vs. Cut Tape & Digi-Reel®), with identical electrical specifications and reset timeout of 160ms. The STM708RM6F from STMicroelectronics provides functional equivalence with a 140ms reset timeout and Totem Pole output configuration, maintaining compatibility within the specified parameter envelope. Component selection should prioritize availability, packaging requirements, and supply chain considerations, as all candidates satisfy the core electrical and mechanical substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can ADM708RARZ replace DS1708RESA+ in existing designs? A: Yes. Both parts share identical 8-SOIC package geometry, 2.63V threshold voltage, single-channel monitoring, push-pull output, and -40°C to 85°C operating range. The ADM708RARZ reset timeout of 160ms exceeds the DS1708RESA+ minimum of 130ms, maintaining functional compatibility.

Q: What is the difference between ADM708RARZ and ADM708RARZ-REEL? A: These parts are electrically identical. ADM708RARZ is supplied in Tube packaging, while ADM708RARZ-REEL is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly process requirements and inventory management preferences.

Q: Is STM708RM6F compatible with DS1708RESA+ applications? A: Yes. The STM708RM6F maintains the same 8-SOIC package, 2.63V threshold, single-channel configuration, and operating temperature range. The Totem Pole output topology is functionally equivalent to push-pull configuration for reset signal generation. Reset timeout of 140ms satisfies the 130ms minimum requirement.

Q: Are all substitute parts RoHS3 compliant? A: Yes. DS1708RESA+, ADM708RARZ, ADM708RARZ-REEL, and STM708RM6F all carry ROHS3 Compliant certification with MSL 1 (Unlimited) rating.

Q: What determines if a part can substitute for DS1708RESA+? A: Substitution requires matching 8-SOIC package, 2.63V threshold voltage, single-channel monitoring, push-pull output capability, active high/active low reset functionality, and -40°C to 85°C operating range. Reset timeout must meet or exceed 130ms minimum.
