IMS05SH181K Equivalent & Substitute Parts

Part Overview

The IMS05SH181K is a 180 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 135 mA maximum current with 4.4Ohm maximum DC resistance. The part is currently in active inventory with 1036 pieces available as new original stock.

Equivalent parts are identified when they maintain identical electrical specifications across inductance value, current rating, DC resistance, and shielding characteristics, combined with compatible through-hole axial packaging.

Substitute Part Grouping Explanation

Substitution eligibility for the IMS05SH181K is determined by strict equivalence across the following critical parameters:

• Inductance value: 180 µH (exact match required)
• Current rating: 135 mA (minimum threshold)
• DC resistance: 4.4Ohm maximum (maximum threshold)
• Shielding type: Shielded (electromagnetic containment requirement)
• Mounting configuration: Through-hole axial (PCB integration compatibility)
• Core material: Ferrite (frequency response and saturation characteristics)

The Bourns 9250A-184-RC meets all substitution criteria, providing electrical and mechanical compatibility with the IMS05SH181K within the specified parameter tolerances.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-184-RC from Bourns Inc. is a direct electrical and mechanical equivalent to the IMS05SH181K. Both components share identical inductance, current rating, and DC resistance specifications with ferrite-shielded axial through-hole construction.

The Bourns substitute carries ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The component is actively manufactured and available in production quantities.

Selection between the two parts should be based on supply chain availability, lead time requirements, and procurement cost. Both components are suitable for direct substitution in existing circuit designs without modification to PCB layout or electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-184-RC replace the IMS05SH181K in existing designs?

A: Yes. Both components meet identical electrical specifications for inductance (180 µH), current rating (135 mA), and DC resistance (4.4Ohm maximum). The axial through-hole packaging is mechanically compatible with standard PCB footprints designed for the IMS05SH181K.

Q: Are there physical dimension differences between these parts?

A: The 9250A-184-RC is specified at 0.162" diameter by 0.410" length (4.11mm x 10.41mm). Physical dimensions for the IMS05SH181K are not provided in the specification data. Verify PCB footprint clearances if space constraints exist in your application.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-184-RC is ROHS3 compliant and REACH unaffected. Compliance documentation should be verified with the supplier if required for your application or regulatory jurisdiction.

Q: Does the ±10% inductance tolerance of the 9250A-184-RC affect circuit performance?

A: Inductance tolerance affects frequency response and impedance characteristics. Verify that ±10% tolerance is acceptable for your circuit design. If tighter tolerance is required, confirm the tolerance specification of the IMS05SH181K with Vishay Dale.

Q: What is the saturation current specification for the IMS05SH181K?

A: Saturation current (Isat) is not specified in the IMS05SH181K data provided. The 9250A-184-RC specifies 85 mA saturation current. Confirm saturation requirements with Vishay Dale if this parameter is critical for your application.
