Equivalent & Substitute Parts for UWR-3.3/4250-D12A-C

Part Overview

The Murata Power Solutions UWR-3.3/4250-D12A-C is an isolated DC-DC converter module. It provides a single output of 3.3V at 4.25A with 15W power capability from a 10V–18V input range. This module is supplied in a 6-DIP Through Hole case with a 1.5 kV isolation rating and is designed for ITE (Commercial) applications. The UWR-3.3/4250-D12A-C is classified as obsolete, which creates a need for identifying substitute models to ensure design continuity in repair, maintenance, or new product manufacturing.

Key Parameters

Substitute Part Grouping Explanation

Potential substitute parts are selected strictly based on conformance to the following allowed parameters in this product category: function (Isolated Module DC-DC Converter), single output topology, input voltage range covering the application need, 3.3V output voltage, equal or greater output current, matching power rating (15W), equal or higher isolation voltage, identical package style (6-DIP Module, Through Hole), and equivalent environmental compliance (ROHS3, REACH). Only substitutes matching these criteria are listed.

Parameter Comparison

Engineering Selection Recommendations

Selection between UWR-3.3/4250-D12A-C and SPM15-033-Q12-C can be performed directly based on matching electrical characteristics (output voltage, current, power, isolation voltage), mechanical compatibility (package and mounting), and certification status (ROHS3, REACH). UWR-3.3/4250-D12A-C is obsolete; SPM15-033-Q12-C is active and fulfills the same compliance requirements, supporting substitution without changes to regulatory documentation.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting DC-DC converter modules in this category?
A1: Substitute modules must match in function (isolated), have an equal or wider input voltage range, the same output voltage, equal or higher output current, same or higher power, appropriate isolation voltage, identical package and mounting type, and equivalent compliance status.

Q2: Is there any mechanical difference in package or mounting?
A2: Both UWR-3.3/4250-D12A-C and SPM15-033-Q12-C are supplied in 6-DIP Module packages and support Through Hole mounting, ensuring mechanical compatibility.

Q3: Are the compliance statuses equivalent for these models?
A3: Both parts are ROHS3 Compliant and REACH Unaffected.

Q4: How does the product status affect part selection?
A4: UWR-3.3/4250-D12A-C is obsolete, therefore an active part such as SPM15-033-Q12-C should be selected to maintain continuous availability.

Q5: What is the difference in input voltage range, and does it affect substitution?
A5: SPM15-033-Q12-C features a wider input voltage range (9V – 36V) compared to UWR-3.3/4250-D12A-C (10V – 18V), which covers the required range.

Q6: Are the electrical ratings equal or higher for the substitute?
A6: SPM15-033-Q12-C delivers the same output voltage (3.3V), higher output current (4.5A vs 4.25A), the same power rating (15W), and higher isolation voltage (1.6 kV vs 1.5 kV).
