DS1233-15 Equivalent & Substitute Parts

Part Overview

The DS1233-15 is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This through-hole mounted component provides reset and power-on reset functionality with an open drain or open collector output configuration. The DS1233-15 is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts for the DS1233-15 are classified based on the following substitution criteria:

Direct Manufacturer Equivalents maintain identical electrical specifications and are sourced from the same manufacturer. These parts are pin-compatible and functionally interchangeable without design modification.

Parametric Equivalents provide the same core electrical performance within the allowed parameter tolerances for this product category. These parts satisfy the functional requirements of the original design.

Manufacturer-Recommended Alternatives are cross-manufacturer substitutes that meet the electrical and mechanical requirements while offering active product status and improved compliance certifications.

The critical parameters determining substitution eligibility are:

Single-channel voltage monitoring capability
4.125V nominal voltage threshold (±tolerance)
Open drain or open collector output
Active low reset logic
TO-92-3 through-hole package compatibility
Operating temperature range of -40°C to 85°C minimum

Engineering Selection Recommendations

DS1233-15+ (Direct Equivalent): This part is the primary substitute for the obsolete DS1233-15. It maintains identical electrical specifications and packaging, providing direct replacement capability. The DS1233-15+ carries active product status and ROHS3 compliance, making it suitable for new designs and production continuity. This option is recommended for applications requiring exact parameter matching.

DS1233D-15+ (Parametric Equivalent): This variant from Analog Devices Inc./Maxim Integrated offers identical electrical performance to the DS1233-15. With active product status and ROHS3 compliance, it provides an alternative within the same manufacturer family. The DS1233D-15+ is suitable for designs where the base product number variant is acceptable.

MCP130-450FI/TO (Cross-Manufacturer Alternative): This Microchip Technology supervisor IC provides functional equivalence with active product status and ROHS3 compliance. The MCP130-450FI/TO operates at a voltage threshold of 4.375V and features a 150ms minimum reset timeout, compared to the DS1233-15's 4.125V threshold and 250ms timeout. This part is suitable for applications where the voltage threshold and reset timing parameters are compatible with the design requirements. Cross-manufacturer substitution requires verification of circuit-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can DS1233-15+ be used as a direct replacement for DS1233-15?

A: Yes. The DS1233-15+ maintains identical electrical specifications, including voltage threshold, output configuration, reset logic, and operating temperature range. Both parts use the TO-92-3 through-hole package. The primary difference is product status: DS1233-15+ is active while DS1233-15 is obsolete.

Q: What is the difference between DS1233-15+ and DS1233D-15+?

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated and provide identical electrical performance. The difference lies in the base product number designation (DS1233 versus DS1233D). Both are active products with ROHS3 compliance and can be used interchangeably in applications requiring the specified parameters.

Q: Can MCP130-450FI/TO replace DS1233-15 in all applications?

A: MCP130-450FI/TO is functionally equivalent but differs in two key parameters: voltage threshold (4.375V versus 4.125V) and reset timeout (150ms minimum versus 250ms minimum). Substitution is valid only when these parameter differences are compatible with the circuit design. Verify that the higher voltage threshold and shorter reset timeout do not affect system operation.

Q: Are all substitute parts available in the same package?

A: Yes. All listed substitute parts use the TO-226-3, TO-92-3 (TO-226AA) package configuration with through-hole mounting, ensuring mechanical compatibility and PCB layout compatibility with the original DS1233-15.

Q: What compliance certifications should I verify for new designs?

A: All active substitute parts (DS1233-15+, DS1233D-15+, and MCP130-450FI/TO) carry ROHS3 compliance and REACH Unaffected status. The original DS1233-15 is RoHS non-compliant. For new designs, select from the active, compliant alternatives to meet current regulatory requirements.
