Equivalent & Substitute Parts for SCWN03C-12
Part Overview
The SCWN03C-12 by MEAN WELL USA Inc. is an isolated DC-DC converter module designed for ITE (Commercial) applications. It features a 12V output at 250mA, a wide input voltage range of 36V to 72V, 3W output power, and a 3 kV isolation rating. The module is mounted through-hole in a 24-DIP package form factor. The active product status and substantial inventory ensure ongoing availability. However, evaluating alternative models is necessary to mitigate supply chain risks, ensure continuity in manufacturing, or address extended procurement cycles.
