JCH1012S3V3 Equivalent & Substitute Parts Reference

Part Overview

The JCH1012S3V3 from XP Power is an active, through-hole, isolated DC-DC converter module delivering 3.3V at up to 2A (10W) from a 9V–18V input supply. It features overcurrent and short-circuit protection, 1.5 kV isolation, and is suitable for ITE (Commercial) applications. Identifying alternative models is necessary for ensuring continuity of supply, second-sourcing strategies, and design flexibility where identical or closely-matching specifications are mandatory.
