Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on the following explicit key parameters: Type (Isolated Module), Number of Outputs (1), Output Voltage (5V), Output Current (3A), Power (15W), Input Voltage Range (must cover the application input range), Voltage Isolation (minimum 1.5 kV), Operating Temperature (-40°C ~ 85°C), Mounting Type (Surface Mount), RoHS and ECCN status, and application suitability (ITE - Commercial). Only parts satisfying all of these criteria are included as substitutes.
