IMS05SH3R3K Equivalent & Substitute Parts

Part Overview

The IMS05SH3R3K 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 they maintain electrical equivalence across critical parameters including inductance value, current rating, DC resistance, shielding type, and package format. Component substitution becomes necessary due to inventory availability, supply chain considerations, or manufacturing discontinuation.

Key Parameters

Substitute Part Grouping Explanation

The 9250A-332-RC from Bourns Inc. qualifies as a direct substitute based on the following electrical and mechanical equivalence criteria:

• Inductance value matches at 3.3 µH
• Current rating is equivalent at 480 mA
• DC resistance specification is identical at 350 mOhm maximum
• Shielding type is shielded, matching the original design requirement
• Package configuration is axial through-hole, maintaining mechanical compatibility
• Tolerance specification of ±10% is acceptable for this inductance value

These parameters define the substitution boundary for this component category. Deviations in any of these core specifications would disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-332-RC is electrically and mechanically equivalent to the IMS05SH3R3K across all specified critical parameters. The Bourns component carries active product status with ROHS3 compliance and REACH unaffected designation, confirming regulatory alignment for current applications.

Selection between these components should be based on availability, lead time, and packaging format requirements. Both components are suitable for direct substitution in through-hole PCB applications requiring 3.3 µH inductance at 480 mA current levels.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-332-RC replace the IMS05SH3R3K in existing designs?

A: Yes. Both components share identical inductance (3.3 µH), current rating (480 mA), DC resistance (350 mOhm maximum), shielding type (shielded), and axial through-hole package configuration. No circuit redesign is required.

Q: Are there physical dimension differences between these components?

A: The 9250A-332-RC is specified at 0.162" diameter × 0.410" length (4.11 mm × 10.41 mm). Verify this dimension against your PCB layout requirements, as the IMS05SH3R3K dimensions were not provided in the specification data.

Q: What is the tolerance specification for inductance?

A: The 9250A-332-RC carries ±10% inductance tolerance. This tolerance is standard for molded inductor components in this category and is suitable for general-purpose filtering and energy storage applications.

Q: Are compliance certifications equivalent?

A: The 9250A-332-RC is ROHS3 compliant and REACH unaffected. Verify that your application requirements align with these regulatory standards before component selection.

Q: Can these components be used interchangeably in high-frequency applications?

A: Both components are shielded molded inductors suitable for through-hole mounting. The 9250A-332-RC specifies a self-resonant frequency of 85 MHz and Q factor of 44 at 7.9 MHz. Confirm these frequency characteristics meet your circuit requirements.
