SCW03A-05 Equivalent & Substitute Parts Reference

Part Overview

The SCW03A-05 by MEAN WELL USA Inc. is an isolated module DC-DC converter in the 3W class, providing a single 5V output and up to 600mA from a 9V–18V input range. The module operates in ITE (commercial) applications and features overcurrent and short-circuit protection. This product is now obsolete and requires alternative models for new designs or replacement in assemblies to ensure ongoing supply and support. Suitable substitute DC-DC converters must meet specified electrical and mechanical characteristics to maintain function and compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based solely on matching key operational and mechanical parameters: isolated module type, single 5V output, compatible 9V–18V input range, equal or greater output current, similar power class, ITE (commercial) application classification, overcurrent and short-circuit protection features, through-hole mounting, 24-DIP package or mechanical compatibility, RoHS and REACH compliance, and equivalent or higher insulation voltage rating. Product status (active/inactive) and applicable certifications are also considered for engineering selection.

Parameter Comparison

Engineering Selection Recommendations

Preference is given to active parts with RoHS3 compliance and REACH unaffected status to meet environmental and supply chain requirements. Both SCWN06A-05 and REC3-1205SRW/H2/A are active, compliant with RoHS and REACH, and feature operational compatibility per the specified key parameters. For certification-critical applications, select parts with appropriate approval agency listings as provided. Choose based on inventory, manufacturer continuity, and required certification fields from the provided attributes.

Frequently Asked Questions (FAQ)

Q: What qualifies a DC-DC converter as an acceptable substitute for SCW03A-05?
A: Acceptable substitutes must match or exceed the specified output voltage, input range, current capacity, isolation voltage, package type, mounting style, and compliance status.

Q: Are the substitute part numbers physically and electrically compatible?
A: Substitute parts SCWN06A-05 and REC3-1205SRW/H2/A share the 24-DIP module, 8 leads package, through-hole mounting, and compatible electrical parameters with SCW03A-05.

Q: What environmental and compliance standards are required for substitution?
A: All compared parts meet ROHS3 compliance, have REACH unaffected status, and hold MSL 1 (unlimited).

Q: Is output power or isolation voltage a limiting factor?
A: Both alternatives provide equal or higher output power and isolation ratings than SCW03A-05.

Q: Can these substitutes be used for ITE (Commercial) applications?
A: All substitute parts are specified as suitable for ITE (commercial) applications.
