DS1832U/T&R Equivalent & Substitute Parts

Part Overview

The DS1832U/T&R is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This component provides push-pull reset output functionality with configurable voltage threshold monitoring and active high/active low reset control. The device is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The DS1832U+T&R serves as the direct functional equivalent with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1832U/T&R is determined by strict equivalence across the following parameters:

• Single-channel voltage monitoring architecture
• Voltage threshold options: 2.55V and 2.88V
• Push-pull output configuration with dual polarity reset control (active high/active low)
• 250ms minimum reset timeout specification
• Operating temperature range: -40°C to 85°C
• Surface mount packaging: 8-TSSOP/8-MSOP form factor with 0.118" (3.00mm) width
• 8-uMAX/uSOP supplier device package designation

The DS1832U+T&R meets all these criteria and is classified as the direct equivalent. Both parts share the same base product number (DS1832) and identical electrical specifications, with the primary distinction being product status and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

The DS1832U+T&R is the direct functional equivalent for the obsolete DS1832U/T&R. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all monitored parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance:

• The DS1832U/T&R is classified as obsolete and carries RoHS non-compliant status
• The DS1832U+T&R is actively manufactured and ROHS3 compliant

For new designs or production continuity, the DS1832U+T&R is the appropriate selection. Both parts maintain identical moisture sensitivity levels (MSL 1), REACH unaffected status, and export classification (EAR99). The electrical performance, thermal operating range, and package form factor are equivalent, ensuring direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can DS1832U+T&R directly replace DS1832U/T&R in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The DS1832U+T&R is the active production equivalent and can be used as a direct substitute without circuit modification.

Q: What is the significance of the RoHS compliance difference?

A: The DS1832U/T&R is RoHS non-compliant, while DS1832U+T&R is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the DS1832U+T&R is the required selection.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-TSSOP/8-MSOP package with 0.118" (3.00mm) width. PCB layout and footprints are interchangeable.

Q: Do both parts support the same voltage threshold options?

A: Yes. Both DS1832U/T&R and DS1832U+T&R support 2.55V and 2.88V threshold configurations with identical reset timeout specifications (250ms minimum).

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any differences in operating temperature range?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C (TA).
