JCK1548D15 Equivalent & Substitute Parts Reference

Part Overview

The XP Power JCK1548D15 is an isolated DC-DC converter module designed for ITE (commercial) applications, delivering ±15V dual output at up to 500mA per channel with a maximum power rating of 15W. Device features include through-hole mounting, a 1.5 kV isolation voltage, overcurrent and short circuit protection, and wide input voltage compatibility (36V to 75V). It is actively available and ROHS3 compliant. Substitution or equivalent selection is required to ensure continued supply chain flexibility and maintain design compatibility in the event of inventory constraints, sourcing changes, or manufacturer directives.
