DS1836CS-10/T&R Equivalent & Substitute Parts

Part Overview

The DS1836CS-10/T&R is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. This device functions as a single-channel battery backup circuit supervisor with push-pull totem pole output configuration. The part is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing system support and new design implementations. The DS1836 series MicroManager supervisor provides voltage monitoring and reset signal generation for microprocessor-based systems requiring reliable power supervision.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1836CS-10/T&R is determined by strict equivalence across the following critical parameters:

• Single-channel voltage monitoring capability
• 2.88V voltage threshold setting
• Push-pull totem pole output configuration
• Active low reset signal polarity
• 200ms minimum reset timeout duration
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and REACH unaffected status

The DS1836CS-10+T&R meets all these criteria and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is product status: the original part is obsolete while the substitute remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The DS1836CS-10+T&R is the direct parametric equivalent for the obsolete DS1836CS-10/T&R. Both components share identical electrical specifications, package configuration, and regulatory compliance certifications. The substitute part maintains active production status, ensuring availability for replacement applications and new designs. Both parts comply with ROHS3 requirements and carry REACH unaffected designation, meeting current environmental and regulatory standards. The transition from the obsolete part number to the active equivalent involves only a packaging tape format change (indicated by the slash-to-plus notation), with no functional or electrical differences.

Frequently Asked Questions (FAQ)

Q: What is the difference between DS1836CS-10/T&R and DS1836CS-10+T&R?

A: The part numbers differ only in tape format designation. The DS1836CS-10/T&R uses one tape configuration while DS1836CS-10+T&R uses an alternative tape format. All electrical parameters, package dimensions, and functional specifications are identical.

Q: Can DS1836CS-10+T&R be used as a direct replacement in existing designs?

A: Yes. The substitute part is electrically and mechanically equivalent. It provides the same single-channel voltage monitoring at 2.88V threshold, identical push-pull totem pole output, and matching 8-SOIC package dimensions.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level remains at MSL 1 (Unlimited) for both variants.

Q: Why is the original part marked as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation decisions by the supplier. The active equivalent DS1836CS-10+T&R provides continued access to the same functionality.

Q: What parameters must match for substitution eligibility?

A: Critical matching parameters include voltage threshold (2.88V), output configuration (push-pull totem pole), reset polarity (active low), reset timeout (200ms minimum), package type (8-SOIC), and operating temperature range (-40°C to 85°C).
