DS1830AS/T&R Equivalent & Substitute Parts

Part Overview

The DS1830AS/T&R is a 3-channel supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring voltage monitoring and sequencing. This component operates as an open drain or open collector supervisor with active low reset functionality and a 10ms, 20ms, or 50ms minimum reset timeout. The DS1830AS/T&R is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution eligibility for the DS1830AS/T&R is determined by strict equivalence across the following critical parameters:

  • Number of voltages monitored: 3 channels
  • Voltage threshold setting: 3.3V
  • Output configuration: Open drain or open collector
  • Reset polarity: Active low
  • Reset timeout specifications: 10ms, 20ms, or 50ms minimum
  • Package type: 8-SOIC surface mount
  • Operating temperature range: -40°C to 85°C

The DS1830AS+T&R qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction between the main part and its substitute is packaging format and product lifecycle status.

Engineering Selection Recommendations

The DS1830AS+T&R is the direct functional equivalent of the DS1830AS/T&R. Both components share identical electrical characteristics, pin configurations, and mechanical specifications. The DS1830AS+T&R is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance. The DS1830AS/T&R, classified as obsolete, should be replaced with the DS1830AS+T&R in systems requiring continued support or component replenishment. The transition between these parts requires no circuit redesign or board layout modifications, as they are pin-for-pin and functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Are the DS1830AS/T&R and DS1830AS+T&R pin-compatible?

A: Yes. Both components use the 8-SOIC package with identical pin assignments, voltage thresholds, output configurations, and reset timing specifications. No circuit modifications are required for substitution.

Q: What is the primary reason to substitute the DS1830AS/T&R?

A: The DS1830AS/T&R is classified as obsolete. The DS1830AS+T&R is the active equivalent and should be used for new designs and inventory replenishment to ensure long-term component availability.

Q: Does the DS1830AS+T&R meet current regulatory compliance standards?

A: Yes. The DS1830AS+T&R is ROHS3 compliant, whereas the DS1830AS/T&R is RoHS non-compliant. This makes the DS1830AS+T&R suitable for applications subject to RoHS regulations.

Q: Can the DS1830AS+T&R be used as a drop-in replacement in existing assemblies?

A: Yes. The DS1830AS+T&R is a direct drop-in replacement. It maintains the same 8-SOIC surface mount package, electrical specifications, and functional behavior as the DS1830AS/T&R.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both the DS1830AS/T&R and DS1830AS+T&R operate across the identical temperature range of -40°C to 85°C (TA).
