DS1831B Equivalent & Substitute Parts

Part Overview

The DS1831B is a multi-voltage supervisor IC from Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This component monitors four voltage channels with programmable thresholds and provides active-low reset output via open drain or open collector configuration. The DS1831B is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the DS1831B is determined by strict equivalence across the following critical parameters:

• Functional Type: Multi-voltage supervisor with 4-channel monitoring capability
• Voltage Thresholds: Identical threshold configuration (3.3V, 5V, Adj, Adj)
• Output Type: Open drain or open collector output
• Reset Behavior: Active-low reset with matching timeout options (10ms, 100ms, 1,000ms minimum)
• Operating Temperature: -40°C to 85°C range
• Package: 16-DIP through-hole form factor
• Electrical Specifications: All electrical parameters must match within the same base product family

The substitute parts DS1831B+ and DS1831+ meet these criteria as variants within the DS1831 base product line, maintaining identical functional and electrical specifications while differing only in packaging format and compliance status.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DS1831B, DS1831B+, and DS1831+—are functionally equivalent and interchangeable at the circuit level. Selection between them is determined by compliance and supply chain requirements:

DS1831B: Original specification. RoHS non-compliant. Use only in applications where RoHS compliance is not required or where legacy component specifications must be maintained.

DS1831B+: Direct substitute with improved compliance status. ROHS3 compliant. Supplied in tube packaging. Recommended for new designs or systems requiring RoHS compliance while maintaining the same electrical and mechanical specifications.

DS1831+: Parametric equivalent with ROHS3 compliance. Supplied in bulk packaging. Suitable for high-volume applications where bulk packaging reduces component handling and cost.

All parts share identical electrical performance, operating temperature range, and package footprint, ensuring drop-in compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can DS1831B+ be used as a direct replacement for DS1831B?

A: Yes. DS1831B+ is electrically and mechanically identical to DS1831B. The primary difference is RoHS3 compliance and tube packaging. Both parts function identically in circuit applications.

Q: What is the difference between DS1831B+ and DS1831+?

A: Both are ROHS3 compliant and functionally equivalent to DS1831B. The difference is packaging format: DS1831B+ is supplied in tube packaging, while DS1831+ is supplied in bulk packaging. Electrical specifications and performance are identical.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 16-DIP (0.300", 7.62mm) through-hole package. PCB layouts designed for DS1831B will accommodate DS1831B+ and DS1831+ without modification.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. DS1831B+, and DS1831+ deliver identical functional specifications to DS1831B.

Q: Which part should be selected for new designs?

A: DS1831B+ or DS1831+ are recommended for new designs due to ROHS3 compliance. Selection between these two depends on packaging requirements: tube for smaller quantities or mixed component orders, bulk for high-volume production.

Q: Are these parts still in production?

A: All three parts are classified as obsolete. However, inventory is available from component distributors. Verify long-term availability with your supplier before committing to production designs.
