DS1233M-3+ Equivalent & Substitute Parts

Part Overview

The DS1233M-3+ is a single-channel supervisor IC from Analog Devices Inc./Maxim Integrated, designed for power management and reset control applications. This device operates as a Simple Reset/Power-On Reset supervisor with an open drain or open collector output configuration. The part is classified as obsolete, making identification of equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1233M-3+ is determined by strict alignment across the following critical parameters:

• Single-channel voltage monitoring capability
• Voltage threshold of 2.72V
• Open drain or open collector output configuration
• Active low reset logic
• 200ms minimum reset timeout
• Through-hole mounting in TO-92-3 package
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and REACH unaffected status

Only components matching all specified electrical and mechanical parameters qualify as direct equivalents. The DS1233M-3+ base product number serves as the primary reference for identifying compatible alternatives within the EconoReset series.

Parameter Comparison

Engineering Selection Recommendations

The DS1233M-3+ is classified as obsolete. Component selection for replacement applications must prioritize ROHS3 compliance and REACH unaffected status to meet current regulatory requirements. The through-hole TO-92-3 package configuration is a fixed mechanical constraint for direct board-level substitution without layout modifications.

The parametric equivalent identified maintains full electrical and mechanical compatibility across all specified parameters. Selection between available inventory should be based on procurement lead times, cost considerations, and supply chain availability rather than technical performance differences, as all qualifying parts meet identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DS1233M-3+?

A: A valid substitute must match all electrical parameters: single-channel monitoring, 2.72V threshold, open drain/open collector output, active low reset, 200ms minimum timeout, and -40°C to 85°C operating range. The package must be TO-92-3 through-hole configuration. Compliance certifications (ROHS3, REACH unaffected) must also align.

Q: Can the DS1233M-3+ be replaced with a different package variant?

A: No. The TO-92-3 through-hole package is a fixed requirement for direct board-level substitution. Alternative packages would require PCB layout modifications and are not considered direct equivalents.

Q: Does the obsolete status affect substitution eligibility?

A: The obsolete status indicates the part is no longer in active production. Equivalent parts must be sourced from existing inventory. All qualifying substitutes must maintain identical electrical specifications and current compliance certifications.

Q: Are there voltage threshold variants within the DS1233M series?

A: Substitution is restricted to parts with the 2.72V threshold specification. Different threshold variants are not interchangeable and do not qualify as equivalents for this application.

Q: What is the significance of the open drain/open collector output configuration?

A: This output type requires external pull-up resistor implementation in the circuit design. Substitutes must maintain this exact output configuration to ensure circuit compatibility without redesign.
