DS1831 Equivalent & Substitute Parts

Part Overview

The DS1831 is a multi-voltage supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This Power Management (PMIC) device monitors four voltage channels with configurable thresholds and provides active-low reset output via open drain or open collector configuration. The DS1831 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the DS1831 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution validity:

Critical Matching Parameters:

• Number of voltage channels monitored: 4
• Voltage threshold configuration: 3.3V, 5V, Adj, Adj
• Output type: Open Drain or Open Collector
• Reset logic: Active Low
• Reset timeout options: 10ms, 100ms, 1,000ms Minimum
• Operating temperature range: -40°C to 85°C
• Package: 16-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

All identified substitute parts maintain identical electrical specifications and physical packaging, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

DS1831B+ is a parametric equivalent substitute with improved compliance status. This part maintains all electrical and mechanical specifications of the original DS1831 while offering ROHS3 compliance, addressing regulatory requirements for new designs and procurement cycles.

DS1831+ is a direct manufacturer equivalent with identical functional specifications. This part also provides ROHS3 compliance and represents an alternative sourcing option within the same product family.

Both substitute parts are suitable for direct replacement in existing applications where the DS1831 is currently specified, provided that packaging format (Tube for DS1831B+, Bulk for DS1831+) aligns with procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can DS1831B+ and DS1831+ be used interchangeably with DS1831?

A: Yes. All three parts share identical electrical specifications, voltage monitoring capabilities, output configurations, and 16-DIP package dimensions. Direct substitution is supported at the circuit level.

Q: What is the primary difference between these substitute parts?

A: The main differences are product packaging format and RoHS compliance status. DS1831 is RoHS non-compliant, while DS1831B+ and DS1831+ are ROHS3 compliant. DS1831B+ is supplied in Tube packaging, and DS1831+ is supplied in Bulk packaging.

Q: Are there any thermal or operating condition differences?

A: No. All three parts operate across the identical temperature range of -40°C to 85°C and maintain the same reset timeout options and voltage threshold configurations.

Q: Which substitute should be selected for new designs?

A: Selection between DS1831B+ and DS1831+ depends on procurement packaging requirements. Both provide ROHS3 compliance suitable for modern manufacturing standards. DS1831B+ offers Tube packaging, while DS1831+ offers Bulk packaging.

Q: Is the 16-DIP through-hole package identical across all three parts?

A: Yes. All parts use the same 16-DIP (0.300", 7.62mm) through-hole package, ensuring PCB layout and assembly compatibility without modification.
