IMS05ST3R3K Equivalent & Substitute Parts

Part Overview

The IMS05ST3R3K is a 3.3 µH shielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring moderate current handling and low DC resistance. This component belongs to the IMS-5 series and is specified for 480 mA maximum current with 350 mOhm maximum DC resistance in an axial package configuration.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range. The primary substitute identified is the 9250A-332-RC from Bourns Inc., which shares identical core electrical specifications and package form factor.

Key Parameters

Substitute Part Grouping Explanation

The 9250A-332-RC qualifies as a direct substitute based on the following parameter alignment:

• Inductance value: 3.3 µH (identical)
• Current rating: 480 mA (identical)
• DC resistance: 350 mOhm maximum (identical)
• Package configuration: Axial through-hole (identical)
• Shielding type: Shielded (identical)
• Core material: Ferrite (identical)

These parameters define the functional and mechanical compatibility requirements for substitution in this inductor category. Both parts meet the electrical performance specifications and physical mounting requirements for equivalent circuit operation.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-332-RC from Bourns Inc. is an active product with ROHS3 compliance certification. Selection between the IMS05ST3R3K and 9250A-332-RC should be based on:

• Availability requirements and inventory status
• Compliance certifications needed for the application (ROHS3 status confirmed for 9250A-332-RC)
• Supplier lead time and supply chain considerations
• PCB layout constraints related to component dimensions

Both parts satisfy identical electrical and mechanical specifications for through-hole inductor applications requiring 3.3 µH inductance at 480 mA current rating with shielded ferrite core construction.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-332-RC directly replace the IMS05ST3R3K in existing designs?

A: Yes. Both components share identical inductance (3.3 µH), current rating (480 mA), DC resistance (350 mOhm maximum), and axial through-hole package configuration. No circuit modifications are required for substitution.

Q: What are the critical parameters for inductor substitution?

A: For this product category, substitution requires matching: inductance value, current rating, DC resistance specification, shielding type, core material, and package form factor. Tolerance specifications should also be considered for precision applications.

Q: Are there physical dimension differences between these parts?

A: The 9250A-332-RC is specified at 0.162" diameter × 0.410" length (4.11 mm × 10.41 mm). Equivalent dimensions should be confirmed for the IMS05ST3R3K to ensure PCB footprint compatibility.

Q: What compliance certifications apply to these parts?

A: The 9250A-332-RC carries ROHS3 compliance certification. Compliance status for the IMS05ST3R3K should be verified with the manufacturer for applications requiring specific regulatory certifications.

Q: How do inductance tolerance specifications affect circuit performance?

A: The 9250A-332-RC specifies ±10% inductance tolerance. Applications requiring tighter tolerance control should confirm tolerance specifications for both parts before selection.
