Vicor VI-J3H-EX Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-J3H-EX is a DC-DC converter in the Isolated Module category, designed to provide 52V at up to 1.44A output with a 42V to 60V input range. It features Overcurrent Protection (OCP) and Short Circuit Protection (SCP), 3 kV isolation, operates in -10°C to 100°C, and offers 88% efficiency in a half-brick, through-hole package. The VI-J3H-EX is obsolete, making it essential to identify substitute models with matching electrical and mechanical parameters for ongoing designs or replacement needs.
