DS1832S Equivalent & Substitute Parts

Part Overview

The DS1832S is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's MicroMonitor™ series, designed for power management applications requiring single-channel voltage monitoring and reset signal generation. This component operates as a simple reset/power-on reset supervisor with push-pull output configuration.

The DS1832S carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement planning. Substitute parts must maintain identical electrical characteristics, package specifications, and operational parameters to ensure direct compatibility without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1832S is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Specification: Single-channel monitoring with identical threshold voltages (2.55V, 2.88V)
• Output Type: Push-pull configuration with active high/active low reset capability
• Reset Timing: 250ms minimum reset timeout
• Thermal Performance: Operating temperature range of -40°C to 85°C
• Physical Package: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Functional Classification: Simple reset/power-on reset supervisor topology

Only parts meeting all these specifications qualify as direct substitutes. The DS1832S+ satisfies all substitution criteria while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The DS1832S+ serves as the direct functional equivalent to the DS1832S, with identical electrical and mechanical specifications across all monitored parameters. The primary distinction lies in product lifecycle status and regulatory compliance.

The DS1832S carries obsolete designation, indicating discontinued manufacturing and limited long-term availability. The DS1832S+ maintains active product status, ensuring ongoing supply chain access and manufacturer support.

From a regulatory perspective, the DS1832S+ achieves ROHS3 compliance, whereas the original DS1832S does not meet this standard. For applications subject to RoHS directives or requiring compliance documentation, the DS1832S+ is the appropriate selection.

Both parts share identical packaging, thermal characteristics, and functional behavior. Selection between these parts should be based on procurement requirements, regulatory obligations, and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can DS1832S+ directly replace DS1832S in existing circuit designs?

A: Yes. The DS1832S+ maintains identical electrical specifications, voltage thresholds, output configuration, reset timing, and 8-SOIC package dimensions. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The DS1832S is classified as obsolete, indicating Analog Devices has discontinued production. The DS1832S+ is active, meaning it remains in current production with ongoing availability. For new designs or long-term supply requirements, the DS1832S+ is the appropriate choice.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical function. Both parts deliver identical performance. RoHS3 compliance of the DS1832S+ is relevant only for applications requiring regulatory adherence to RoHS directives.

Q: Are there any package or mounting differences?

A: No. Both parts use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width. PCB footprints and assembly processes remain unchanged.

Q: What voltage thresholds are available?

A: Both the DS1832S and DS1832S+ support threshold options of 2.55V and 2.88V. Specific threshold selection depends on the part number variant and application requirements.

Q: Is the reset timeout specification identical?

A: Yes. Both parts specify a 250ms minimum reset timeout with active high/active low reset logic configuration.
