DS1831CS Equivalent & Substitute Parts

Part Overview

The DS1831CS is a multi-voltage supervisor IC from Analog Devices Inc./Maxim Integrated, designed for power management applications requiring monitoring of four voltage channels. This device features open drain or open collector output with active low reset functionality and is housed in a 16-SOIC surface mount package. The DS1831CS is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1831CS is determined by strict equivalence across the following critical parameters:

• Number of voltage channels monitored: 4 channels
• Voltage threshold configuration: 2.5V, 3.3V, Adj, Adj
• Output architecture: Open Drain or Open Collector
• Reset polarity: Active Low
• Reset timeout options: 10ms, 100ms, 1,000ms Minimum
• Package specification: 16-SOIC surface mount
• Operating temperature range: -40°C ~ 85°C (TA)

The DS1831CS+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is product status and compliance certification, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The DS1831CS+ is the direct functional equivalent of the DS1831CS. Both parts share identical electrical specifications, pin configuration, and package geometry, ensuring drop-in compatibility at the circuit board level.

The DS1831CS+ is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance. The original DS1831CS, classified as obsolete, presents supply chain risk and does not meet current regulatory compliance requirements.

For legacy systems currently using the DS1831CS, transition to the DS1831CS+ is supported without circuit modification, as all monitored voltage thresholds, output characteristics, reset behavior, and operating parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can the DS1831CS+ be used as a direct replacement for the DS1831CS?

A: Yes. The DS1831CS+ is electrically and mechanically identical to the DS1831CS. Both devices monitor four voltage channels with identical threshold configurations (2.5V, 3.3V, Adj, Adj), feature open drain or open collector output, and are packaged in 16-SOIC surface mount form factor. No circuit modifications are required.

Q: What is the primary difference between the DS1831CS and DS1831CS+?

A: The DS1831CS is classified as obsolete, while the DS1831CS+ maintains active product status. Additionally, the DS1831CS+ is ROHS3 compliant, whereas the DS1831CS is RoHS non-compliant. Electrical and functional specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both the DS1831CS and DS1831CS+ use the 16-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and electrical interface.

Q: What voltage thresholds are available on these supervisor ICs?

A: The DS1831CS and DS1831CS+ monitor four channels with fixed thresholds of 2.5V and 3.3V on two channels, and adjustable thresholds on the remaining two channels.

Q: What is the reset timeout specification for these devices?

A: Both parts support selectable reset timeout options of 10ms, 100ms, or 1,000ms minimum, depending on device configuration.
