Equivalent & Substitute Parts for EC3A37M

Part Overview

The EC3A37M from Cincon Electronics Co. LTD is an isolated DC DC converter module, delivering a single 3.3V output at 600mA from a 36V to 72V input range. This 2W isolated power module is suited for ITE (Commercial) applications and incorporates features such as short-circuit protection (SCP). It is supplied in a 24-DIP Module, 14-lead through-hole package. The part is currently active and compliant with ROHS3 and REACH standards.
Finding alternative models is necessary in situations of supply chain management, inventory planning, or design redundancy to ensure continued availability, especially in systems where this module is a critical power supply resource.
