Equivalent & Substitute Parts for ISA1224 DC DC Converter

Part Overview

The XP Power ISA1224 is an isolated DC DC converter module supporting dual output voltages of +24V and -24V at 21mA each, with an input voltage range of 10.8V to 13.2V and power rating of 1W. The device is surface-mount in a 10-SMD package and designed for ITE (commercial) applications, featuring short circuit protection and 1.5 kV isolation. As the ISA1224 is classified as obsolete, identifying engineering-approved substitutes is critical for continuity in design and maintenance.

Substitute Part Grouping Explanation

Substitute selection for the ISA1224 DC DC converter is strictly based on the following critical parameters:

  • Output configuration: Dual output (+24V, -24V at 21mA each)
  • Input voltage range (10.8V - 13.2V)
  • Power rating (1W)
  • Isolation voltage (1.5 kV)
  • Package type and footprint (10-SMD Module, 6 Leads surface mount)
  • Application type (ITE, commercial)
  • Operating temperature range
  • Efficiency
  • Compliance and product status

Substitute parts must match the above electrical and mechanical specifications. Only parts listed with these matching characteristics are valid substitutes.
