DS1233M-3 Equivalent & Substitute Parts

Part Overview

The DS1233M-3 is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power management and reset control applications. This component monitors a single voltage channel and provides active-low reset output through an open-drain or open-collector configuration. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1233M-3 is determined by strict equivalence across the following critical parameters:

• Single voltage channel monitoring capability
• 2.72V threshold voltage specification
• Open-drain or open-collector output configuration
• Active-low reset logic
• 200ms minimum reset timeout
• TO-92-3 through-hole package compatibility
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance and REACH unaffected status

The DS1233M-3+ qualifies as a parametric equivalent substitute based on identical specifications across all monitored electrical and mechanical parameters. Both components share the same base product number (DS1233M) and are manufactured by the same supplier, ensuring functional interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The DS1233M-3+ serves as a direct parametric equivalent for the obsolete DS1233M-3. Both components maintain identical electrical specifications, package configuration, and regulatory compliance status. Selection between these parts should be based on availability and inventory considerations rather than functional differences.

Both the DS1233M-3 and DS1233M-3+ are classified as obsolete products. For new designs or long-term system support, evaluation of current-generation supervisor ICs from Analog Devices Inc./Maxim Integrated with equivalent functional specifications may be warranted, though such alternatives fall outside the scope of direct substitution parameters defined for this component.

Compliance certifications—ROHS3 compliance and REACH unaffected status—are maintained across both parts, ensuring regulatory requirements are satisfied in either selection.

Frequently Asked Questions (FAQ)

Q: Can the DS1233M-3+ be used as a direct replacement for the DS1233M-3?

A: Yes. The DS1233M-3+ is a parametric equivalent with identical electrical specifications, threshold voltage, output configuration, reset timing, operating temperature range, and package type. Direct substitution is supported without circuit modification.

Q: What determines whether a part qualifies as a substitute for the DS1233M-3?

A: Substitution is based on matching the following parameters: single voltage channel monitoring, 2.72V threshold voltage, open-drain or open-collector output, active-low reset logic, 200ms minimum reset timeout, TO-92-3 through-hole package, -40°C to 85°C operating temperature range, and equivalent regulatory compliance status.

Q: Are there any package or pinout differences between the DS1233M-3 and DS1233M-3+?

A: No. Both components use the TO-226-3 and TO-92-3 (TO-226AA) package designations with identical through-hole mounting configuration and pinout.

Q: What is the significance of the product status being listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. Substitute parts should be identified for ongoing system maintenance and future production requirements. The DS1233M-3+ provides functional continuity for existing applications.

Q: Do both parts meet the same regulatory and compliance requirements?

A: Yes. Both the DS1233M-3 and DS1233M-3+ are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.
