Equivalent & Substitute Parts Reference: IE0509SH
Part Overview
IE0509SH from XP Power is an active isolated module DC-DC converter designed for ITE (Commercial) applications. It delivers a regulated 9V output at up to 111mA from a 4.5V–5.5V input range, with an output power of 1W. The module features a 4-SIP through-hole package and operates across a -40°C to 85°C temperature range. Finding substitutes is essential for ensuring supply continuity, matching form-factors, and maintaining compliance with design requirements when availability or lead times are critical.

Engineering Selection Recommendations
Both IE0509SH and SMU01L-09 are active, ROHS3-compliant DC-DC converters in the 1W isolated module category with 4-SIP through-hole packages and matching input/output parameters. The key distinction is the isolation rating: IE0509SH offers 3 kV, while SMU01L-09 has 1.5 kV. Product status and moisture sensitivity level match. For applications where the isolation voltage and mounting form factor meet system requirements, either part may be directly selected within the bounds of the provided technical data.
