DS1831+ Equivalent & Substitute Parts

Part Overview

The DS1831+ is a multi-voltage supervisor IC from Analog Devices Inc./Maxim Integrated, designed for power management applications requiring monitoring of multiple supply voltages. This 16-DIP through-hole component provides open drain or open collector output with active low reset functionality across four monitored channels. The product is classified as obsolete, making identification of equivalent and substitute parts essential for legacy system maintenance and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1831+ is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Number of voltages monitored (4 channels), voltage threshold levels (3.3V, 5V, Adj, Adj), output configuration (open drain or open collector), reset logic (active low), and reset timeout options (10ms, 100ms, 1,000ms minimum)
• Physical Package: 16-DIP form factor with 0.300" (7.62mm) pitch for through-hole mounting compatibility
• Environmental Compliance: ROHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity)
• Thermal Performance: Operating temperature range of -40°C to 85°C

The DS1831B+ qualifies as a parametric equivalent substitute, maintaining identical electrical and mechanical specifications while differing only in packaging format (tube versus bulk).

Parameter Comparison

Engineering Selection Recommendations

Both the DS1831+ and DS1831B+ are classified as obsolete products and maintain full parametric equivalence across all electrical, mechanical, and environmental specifications. Selection between these parts should be based on packaging requirements and inventory availability. The DS1831+ is supplied in bulk packaging, while the DS1831B+ is supplied in tube packaging. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility in legacy system applications.

Frequently Asked Questions (FAQ)

Q: Can DS1831B+ be used as a direct replacement for DS1831+? A: Yes. The DS1831B+ is a parametric equivalent with identical electrical specifications, voltage thresholds, output configuration, reset logic, and package dimensions. The only difference is packaging format (tube versus bulk).

Q: Are there any pin compatibility concerns when substituting between these parts? A: No. Both parts use the 16-DIP (0.300", 7.62mm) package with identical through-hole mounting specifications, ensuring direct PCB compatibility.

Q: Do both parts meet the same compliance standards? A: Yes. Both DS1831+ and DS1831B+ are ROHS3 compliant with MSL rating of 1 (unlimited), meeting identical environmental and regulatory requirements.

Q: What is the significance of the product status being obsolete? A: Obsolete status indicates these parts are no longer manufactured. Substitution between available inventory of DS1831+ and DS1831B+ is necessary for system maintenance and repair applications.

Q: Are the reset timeout specifications identical between both parts? A: Yes. Both parts support identical reset timeout options of 10ms, 100ms, and 1,000ms minimum, ensuring equivalent timing behavior in power management circuits.
