Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1831BS/T&R is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Channels: All substitute parts must monitor exactly 4 voltage channels
• Voltage Thresholds: Threshold configuration must match 3.3V, 5V, Adj, Adj
• Output Configuration: Open drain or open collector output topology
• Reset Characteristics: Active low reset with matching timeout options (10ms, 100ms, 1,000ms minimum)
• Operating Temperature Range: -40°C to 85°C
• Package Specification: 16-SOIC surface mount package with identical physical dimensions
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The identified substitute parts DS1831BS+T&R and DS1831S+T&R meet all these criteria and are sourced from the same manufacturer within the MicroMonitor™ series.

Parameter Comparison

Engineering Selection Recommendations

The DS1831BS/T&R is classified as obsolete, necessitating transition to active product alternatives. Both substitute parts—DS1831BS+T&R and DS1831S+T&R—maintain full parametric equivalence and are currently in active production status.

DS1831BS+T&R represents a direct substitute with identical electrical and mechanical specifications. This part is recommended as the primary replacement option, with current inventory of 857 units available.

DS1831S+T&R serves as a parametric equivalent, offering identical functional performance and compliance certifications. This alternative is suitable where DS1831BS+T&R availability is constrained, with 661 units currently in stock.

Both alternatives satisfy ROHS3 compliance requirements and maintain the MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between the two active alternatives should be based on procurement availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can DS1831BS+T&R and DS1831S+T&R be used interchangeably with DS1831BS/T&R?

A: Yes. Both substitute parts maintain identical electrical parameters, voltage monitoring configuration, output characteristics, reset functionality, and package specifications. They are direct functional equivalents suitable for board-level replacement.

Q: What is the difference between DS1831BS+T&R and DS1831S+T&R?

A: Both parts are parametrically equivalent across all monitored electrical and mechanical parameters. The difference lies in product designation and internal manufacturing specifications. Selection should be based on availability and procurement lead times.

Q: Are the substitute parts compatible with existing PCB designs for DS1831BS/T&R?

A: Yes. Both substitute parts use the identical 16-SOIC package with matching pin configuration, physical dimensions (0.154" width, 3.90mm), and surface mount footprint. No PCB redesign is required.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both DS1831BS+T&R and DS1831S+T&R are ROHS3 compliant with MSL 1 rating, matching the compliance profile of the original DS1831BS/T&R.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across the identical temperature range of -40°C to 85°C (TA), maintaining thermal performance specifications of the original component.
