Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMS05ST392K are qualified based on the following critical electrical and mechanical parameters:

• Inductance Value: 3.9 mH (primary electrical specification)
• Current Rating: 35 mA (maximum continuous current capability)
• DC Resistance: 73.8 Ohm Max (power dissipation and circuit performance)
• Shielding: Shielded (electromagnetic interference containment)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Axial (physical form factor and footprint)

The substitute part 9250A-395-RC from Bourns Inc. meets all these critical parameters and is therefore classified as a direct equivalent for the IMS05ST392K.
