ISE1209A-TR Equivalent & Substitute Parts Reference

Part Overview

The ISE1209A-TR from XP Power is an isolated module DC-DC converter with 1 output, rated for 9V and 111mA, operating from a 10.8V to 13.2V input voltage range. As part of the ISE (1W) series, this converter is designed for ITE (Commercial) applications with surface mount 8-SMD Module packaging. The product is obsolete, prompting the requirement for direct substitutes that match its electrical and mechanical specifications for applications where such modules are needed.
