Equivalent & Substitute Parts Reference: EC3A21

Part Overview

The EC3A21 from Cincon Electronics Co. LTD is an isolated module DC-DC converter designed for ITE (Commercial) applications, providing a regulated 5V output at up to 600mA from an 18V–36V input range. Featuring SCP and through-hole mounting in a 24-DIP Module package, this 3W converter is currently listed as "Active" and ROHS3 Compliant, with substantial inventory. Engineers may need alternative models due to planning for continuity, comparison required by procurement processes, or inventory allocation.
