DS1832S/T&R Equivalent & Substitute Parts

Part Overview

The DS1832S/T&R is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's MicroMonitor™ series, designed for power management applications requiring single-channel voltage monitoring and reset signal generation. This component operates as a simple reset/power-on reset supervisor with push-pull output configuration.

The DS1832S/T&R carries an obsolete product status, making identification of compatible substitute parts essential for ongoing system support, maintenance, and new design implementations where this functionality remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1832S/T&R is determined by strict alignment across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single-channel voltage monitoring
• Voltage Threshold Specifications: 2.55V and 2.88V threshold options
• Output Configuration: Push-Pull output with Active High/Active Low reset capability
• Reset Timeout: 250ms minimum specification
• Operating Temperature Range: -40°C to 85°C
• Package Format: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Electrical Characteristics: Identical voltage monitoring and reset signal generation behavior

The substitute part DS1832S+T&R maintains complete electrical and mechanical compatibility with the original DS1832S/T&R, differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The DS1832S+T&R serves as the direct functional equivalent to the obsolete DS1832S/T&R. Both parts share identical electrical specifications, voltage monitoring thresholds, reset timing characteristics, and 8-SOIC package dimensions.

The primary distinction lies in product lifecycle status and regulatory compliance. The DS1832S+T&R maintains active product status with ROHS3 compliance, whereas the DS1832S/T&R is obsolete and RoHS non-compliant. For new designs or systems requiring long-term component availability and regulatory alignment, the DS1832S+T&R is the appropriate selection.

Both parts are available in compatible packaging formats suitable for surface mount assembly. Inventory availability differs, with the DS1832S+T&R offering significantly higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can DS1832S+T&R replace DS1832S/T&R in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The DS1832S+T&R provides the same voltage monitoring thresholds (2.55V, 2.88V), push-pull output configuration, active high/active low reset capability, and 250ms minimum reset timeout. The 8-SOIC package dimensions are identical, enabling direct board-level substitution.

Q: What is the difference between the packaging designations T&R and +T&R?

A: T&R indicates Digi-Reel® packaging. The +T&R designation indicates availability in both Cut Tape (CT) and Digi-Reel® formats. Both are surface mount compatible packaging options suitable for automated assembly processes.

Q: Why is the DS1832S/T&R marked as obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The DS1832S+T&R remains in active production and is the recommended source for ongoing component procurement.

Q: Are there compliance differences between these parts?

A: Yes. The DS1832S+T&R is ROHS3 compliant, while the DS1832S/T&R is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the DS1832S+T&R is the appropriate selection.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the DS1832S/T&R and DS1832S+T&R operate from -40°C to 85°C (TA), supporting identical thermal specifications for industrial and commercial applications.

Q: Are the moisture sensitivity levels identical?

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