ISH1205A-H Equivalent & Substitute Parts Reference

Part Overview

The ISH1205A-H from XP Power is an obsolete DC-DC converter in the isolated module category, offering a single 5V output at up to 400mA from a 10.8V–13.2V input range. It features surface-mount packaging, 3 kV isolation, a compact 8-SMD, 5-lead case, and ROHS3 compliance. Since the ISH1205A-H is no longer available as new production, identifying alternative compatible models is required to maintain ongoing production or servicing of existing designs using this module.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected on the basis of identical electrical and mechanical parameters. The substitution logic includes input voltage range (10.8V–13.2V), output voltage (5V), maximum output current (400mA), power (2 W), isolation voltage (3 kV), operating temperature range (-40°C ~ 105°C for both parts, with derating as noted), surface-mount type, 8-SMD module package, single output, application in ITE (Commercial), and ROHS3 compliance. These key parameters ensure functional and physical interchangeability in the target application.

Parameter Comparison

Engineering Selection Recommendations

Based strictly on provided data, the ISH1205A-H is obsolete whereas the F1205XT-2WR3 from Mornsun America, LLC is active and available. Both meet ROHS3 environmental compliance requirements. The substitute part offers certifications (CB, CE, cURus, UL) and conforms to standard 62368-1, also provided in the input. The operating temperature range and mechanical package are consistent with the original component.
