SCW05B-05 Equivalent & Substitute Parts Reference
Part Overview
The SCW05B-05 from MEAN WELL USA Inc. is an isolated module DC-DC converter with a single 5V output at up to 1A, 18V–36V input range, and a 5W power rating. It features a through-hole 24-DIP module package with integrated protection (OCP, SCP), is RoHS3 compliant, and supports ITE (Commercial) applications. This product is now classified as obsolete, necessitating the selection of compatible alternative or substitute DC-DC converters with matching electrical, mechanical, and compliance parameters for continued or new designs.

Substitute Part Grouping Explanation
The substitutes for SCW05B-05 have been selected based strictly on matching the following key parameters: input voltage range (18V–36V), output voltage (5V), output current capability (≥1A), power rating (≥5W), isolation voltage (≥1kV), mounting type (through-hole), identical package (24-DIP Module, 8 Leads), and RoHS3 compliance. Only parts with these directly matching or exceeding specifications are listed as substitutes.

Engineering Selection Recommendations
When selecting a substitute for the obsolete SCW05B-05 DC-DC converter, only parts with matching or higher electrical ratings, equivalent mechanical form factor, compliant RoHS3 and REACH status, and active product status qualify. Both MEAN WELL SCWN06B-05 and Delta Electronics DH06S2405A are active, RoHS3 compliant, and meet or exceed all key parameters for both electrical and mechanical compatibility.
Frequently Asked Questions (FAQ)
Q1: What are the primary substitution criteria for SCW05B-05?
A1: The main substitution criteria are identical input voltage range (18–36V), output voltage (5V), output current (≥1A), power rating (≥5W), package/footprint (24-DIP Module, 8 Leads), through-hole mounting, and RoHS3 compliance.
Q2: Are the substitute parts footprint-compatible with SCW05B-05?
A2: All listed substitutes use the 24-DIP Module, 8 Leads through-hole package, matching the mechanical footprint of the SCW05B-05.
Q3: Do the substitute parts provide higher isolation voltages or additional protections?
A3: SCWN06B-05 provides increased isolation voltage (3kV vs. 1kV) and includes UVLO. DH06S2405A provides 1.5kV isolation and UVLO.
Q4: What compliance standards are met by the substitutes?
A4: All substitutes are RoHS3 compliant and REACH unaffected.
Q5: Can these substitutes operate within the same temperature range?
A5: Both substitutes have operating temperature ranges at or above the SCW05B-05 specification.
Q6: Are the substitute parts currently active products?
A6: Both SCWN06B-05 and DH06S2405A are active products according to the provided information.
