Key Parameters

Substitute Part Grouping Explanation

The substitute part selection is determined using only matched or exceeded values for critical parameters. These include output voltage, output current, input voltage range, power rating, package dimensions, mounting type, number of outputs, application standards, and approval/compliance status. Parts are grouped for substitution only if all provided electrical, mechanical, and regulatory parameters align or exceed those of the main part.

Key substitution parameters:

• Voltage - Input and Output
• Current - Output (Max)
• Power (Watts)
• Efficiency
• Number of Outputs
• Mounting Type and Package / Case
• Size / Dimension
• Approval Agency and Standard Number
• Product Category and Application
• Operating Temperature
• Weight (as a factor for mechanical compatibility)
• Compliance status (REACH, ECCN, HTSUS, MSL)

Parameter Comparison
