DS1233A-15+ Equivalent & Substitute Parts

Part Overview

The DS1233A-15+ is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This device monitors a single voltage rail and provides active-low reset output via open drain or open collector configuration. The DS1233A-15+ is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Finding equivalent parts may be necessary due to inventory constraints, supply chain requirements, or design flexibility needs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1233A-15+ is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel
• 2.72V threshold voltage
• Open drain or open collector output configuration
• Active low reset logic
• 250ms minimum reset timeout
• TO-92-3 through-hole package
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance and REACH unaffected status

Only parts meeting all these specifications simultaneously qualify as direct substitutes. The DS1233A-15+ represents the baseline configuration within the EconoReset series for this voltage threshold and package type.

Parameter Comparison

Engineering Selection Recommendations

The DS1233A-15+ maintains Active product status with full regulatory compliance (RoHS3 and REACH unaffected). Selection of this part is appropriate for applications requiring a single-channel supervisor with 2.72V threshold in through-hole TO-92-3 packaging. The device's MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. Active status ensures continued availability and manufacturer support for production applications.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the DS1233A-15+? A: A valid substitute must match all critical parameters: single voltage monitoring channel, 2.72V threshold, open drain/open collector output, active low reset, 250ms minimum timeout, TO-92-3 package, and -40°C to 85°C operating range.

Q: Can I use a different voltage threshold variant as a substitute? A: No. Voltage threshold is a primary selection criterion. Different threshold variants (such as 2.63V or 2.93V) are distinct parts and not interchangeable without circuit redesign.

Q: Is the TO-92-3 package interchangeable with other package options? A: No. Package type is a fixed mechanical and electrical specification. TO-92-3 through-hole packages are not compatible with surface-mount alternatives or different pin configurations.

Q: Does RoHS3 compliance affect substitution eligibility? A: Yes. All substitute parts must maintain RoHS3 compliance and REACH unaffected status to meet regulatory requirements in target markets.

Q: What is the significance of the 250ms reset timeout specification? A: The 250ms minimum reset timeout is a functional parameter that determines system initialization behavior. Substitutes must match this specification to ensure identical power-on reset timing.
