JCK2012S05 Equivalent & Substitute DC-DC Converter Parts Reference

Part Overview

The JCK2012S05 by XP Power is an active, through-hole isolated DC DC converter module from the JCK (20W) series. It delivers a single 5V output at up to 4A from a 9V–18V input range, with 1.6 kV isolation, and features such as remote on/off, OCP, OVP, SCP, and UVLO. Finding alternative models is essential for ensuring supply continuity, multi-source qualification, and risk management for designs requiring identical electrical characteristics and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are selected based on matching the following key parameters: isolated module type, output voltage (5V), maximum output current (4A), input voltage range (9V to 18V), power rating (20W), ITE (Commercial) application suitability, through-hole mounting, 6-DIP module package, and compliance with relevant RoHS and MSL standards. Only parts sharing all these characteristics are listed as functional equivalents.

Parameter Comparison
