Equivalent & Substitute Parts Reference: ISE0509A

Part Overview

The ISE0509A, from XP Power, is an obsolete DC-DC converter categorized as an isolated module. It offers a single 9V output at up to 111mA, accepts 4.5V–5.5V input, and provides 1W power dissipation with surface mount packaging. Its critical mechanical and electrical parameters include isolation voltage, output and input voltage range, output current, and mounting format. Due to its obsolete status, identifying substitute parts that strictly match its electrical and mechanical specifications is essential for maintaining system compatibility and compliance.
