IH4815S Equivalent & Substitute Parts Reference

Part Overview

The IH4815S from XP Power is an isolated DC-DC converter module providing dual output voltages of +15V and -15V at 66mA each with a 2W power rating. The device accepts a 43.2V to 52.8V DC input and features a 1kV isolation, designed for ITE (Commercial) applications. The part is currently classified as obsolete. When a product is obsolete, sourcing identical new-original stock is challenging, making the identification of compatible substitute models essential to maintain system functionality and long-term support.

Key Parameters

Substitute Part Grouping Explanation

Substitute consideration for the IH4815S is based strictly on matching core electrical and mechanical parameters, including: number of outputs, input voltage range, output voltages, output currents, isolation voltage, power rating, mounting type, and package/case. Compliance parameters such as RoHS status and product status (active/obsolete) are also included. Only products aligning with or exceeding these critical parameters are considered as valid functional alternatives.
