Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMS05SH3R9K is determined by strict equivalence in the following parameters:

• Inductance value: 3.9 µH
• Current rating: 450 mA minimum
• DC resistance: 400 mOhm maximum
• Shielding requirement: Shielded configuration
• Mounting configuration: Through-hole axial package
• Core material: Ferrite

The substitute part 9250A-392-RC from Bourns Inc. meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-392-RC from Bourns Inc. is a direct substitute for the IMS05SH3R9K based on matching electrical and mechanical specifications. The substitute part carries active product status and meets ROHS3 compliance and REACH unaffected designations. Selection between the main part and substitute should be based on availability, lead time, and procurement requirements, as both components satisfy the specified functional parameters for 3.9 µH shielded molded inductor applications at 450 mA current rating.

Frequently Asked Questions (FAQ)

Q: What makes the 9250A-392-RC a valid substitute for the IMS05SH3R9K?

A: Both components share identical inductance (3.9 µH), current rating (450 mA), DC resistance (400 mOhm max), shielding configuration, and through-hole axial package type. These parameters define functional equivalence for this inductor category.

Q: Are there any physical dimension differences between these parts?

A: The 9250A-392-RC is specified at 0.162" diameter x 0.410" length (4.11mm x 10.41mm). Physical dimensions for the IMS05SH3R9K are not provided in the available data. Verify board layout compatibility before substitution if space constraints are critical.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-392-RC is ROHS3 compliant and REACH unaffected. Compliance status for the IMS05SH3R9K is not specified in the available documentation.

Q: Can these parts be used interchangeably in all applications?

A: Yes, provided the application requirements do not exceed the specified electrical parameters (3.9 µH inductance, 450 mA current, 400 mOhm DCR maximum) and the through-hole axial package is compatible with the circuit board design.

Q: What is the inductance tolerance for each part?

A: The 9250A-392-RC specifies ±10% inductance tolerance. Tolerance information for the IMS05SH3R9K is not provided. Confirm tolerance requirements for your application before selection.
