DS1831CS+ Equivalent & Substitute Parts

Part Overview

The DS1831CS+ is a multi-voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This Power Management (PMIC) device monitors four voltage channels and provides active-low reset output via open drain or open collector configuration. The DS1831CS+ is classified as an Active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current production applications requiring voltage supervision across multiple supply rails.

Identifying equivalent and substitute parts for the DS1831CS+ is necessary when addressing supply chain constraints, inventory optimization, or design flexibility requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitute parts for the DS1831CS+ must satisfy all critical electrical and mechanical parameters to ensure direct interchangeability. The substitution criteria are based strictly on the following parameters:

• Voltage Monitoring Channels: Exactly 4 channels required
• Voltage Threshold Configuration: 2.5V, 3.3V, Adj, Adj matching
• Output Type: Open Drain or Open Collector configuration
• Reset Logic Level: Active Low
• Reset Timeout Options: Support for 10ms, 100ms, and 1,000ms minimum timeouts
• Package Specification: 16-SOIC (0.154", 3.90mm Width) surface mount
• Operating Temperature Range: -40°C to 85°C (TA)
• Compliance Requirements: RoHS3 compliance and REACH unaffected status

Based on the provided input parameters, the DS1831CS+ is identified as a direct equivalent to itself. No alternative part numbers with differing manufacturer sources or specifications are provided in the substitute list.

Engineering Selection Recommendations

The DS1831CS+ maintains Active product status with full RoHS3 compliance and REACH unaffected classification, confirming its suitability for current production designs. The device is available in Tube packaging with 4102 pieces in new original stock, supporting immediate procurement requirements.

When selecting the DS1831CS+ or its equivalents, confirm that your application requirements align with the specified voltage threshold configuration (2.5V, 3.3V, Adj, Adj), reset timeout duration, and open drain or open collector output requirements. The 16-SOIC package and surface mount configuration are fixed parameters that must match your PCB design specifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DS1831CS+?

A: A valid substitute must match all electrical parameters including the four-channel voltage monitoring configuration, 2.5V and 3.3V threshold settings with two adjustable channels, active-low reset logic, and available reset timeout options (10ms, 100ms, 1,000ms). The package must be 16-SOIC surface mount, and compliance certifications (RoHS3, REACH unaffected) must be maintained.

Q: Can I use a different package variant of the DS1831?

A: No. The DS1831CS+ is specified for 16-SOIC (0.154", 3.90mm Width) surface mount packaging. Alternative package types would require PCB redesign and are not considered direct substitutes.

Q: Are there voltage threshold variations available?

A: The DS1831CS+ features a fixed threshold configuration of 2.5V, 3.3V, Adj, Adj. Substitutes must maintain this exact configuration. Different threshold combinations represent different product variants and are not interchangeable.

Q: What is the significance of the open drain or open collector output?

A: The open drain or open collector output configuration allows the reset signal to be pulled low when a voltage fault is detected. This output type must be maintained in any substitute part to ensure compatibility with existing pull-up resistor networks in your circuit design.

Q: Does the DS1831CS+ support adjustable voltage thresholds?

A: Yes. Two of the four monitored channels feature adjustable voltage thresholds, while the other two are fixed at 2.5V and 3.3V respectively. Substitute parts must provide this same mixed fixed and adjustable threshold capability.
