IMS05STR33K Equivalent & Substitute Parts

Part Overview

The IMS05STR33K is a 330 nH shielded molded inductor manufactured by Vishay Dale, designed for through-hole mounting applications requiring fixed inductance with moderate current handling. This component belongs to the IMS-5 series and is specified for 780 mA operation with a maximum DC resistance of 130 mOhm. The part is currently in stock with 968 pieces available as new original inventory.

Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components from qualified manufacturers that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMS05STR33K is determined by strict equivalence across the following critical parameters:

• Inductance Value: 330 nH (exact match required)
• Current Rating: 780 mA minimum
• DC Resistance: 130 mOhm maximum
• Shielding Configuration: Shielded construction
• Mounting Technology: Through-hole axial package
• Core Material: Ferrite

The Bourns 9250A-331-RC meets all specified criteria and qualifies as a direct electrical and mechanical equivalent. Both components share identical inductance, current handling capacity, DC resistance specification, and physical form factor. The substitute maintains shielded construction and ferrite core material, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-331-RC from Bourns Inc. is qualified as a direct substitute for the IMS05STR33K based on electrical parameter equivalence and mechanical compatibility. The substitute component carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection between the primary part and substitute should be based on availability, lead time requirements, and supply chain considerations. Both components are available as new original stock and maintain identical functional specifications for 330 nH inductance applications at 780 mA operation.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-331-RC be used as a direct replacement for the IMS05STR33K in existing designs?

A: Yes. Both components share identical inductance (330 nH), current rating (780 mA), DC resistance (130 mOhm maximum), shielding configuration, and axial through-hole package format. No circuit modifications are required.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is based on exact inductance value (330 nH), minimum current rating (780 mA), maximum DC resistance (130 mOhm), shielded construction, ferrite core material, and through-hole axial mounting. Deviation from any of these parameters disqualifies a component as a direct equivalent.

Q: Are there differences in performance characteristics between these two parts?

A: The Bourns 9250A-331-RC provides additional documented specifications including inductance tolerance (±10%), saturation current (780 mA), quality factor (46 @ 25 MHz), self-resonant frequency (250 MHz), and operating temperature range (-55°C ~ 125°C). The IMS05STR33K does not provide these detailed specifications in the available documentation. Both parts meet the core electrical requirements.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-331-RC carries ROHS3 compliance and REACH unaffected status. Compliance information for the IMS05STR33K is not provided in the available data.

Q: Are there packaging or form factor differences?

A: No. Both components are specified as axial through-hole inductors with identical physical mounting requirements. The package format is compatible with standard PCB layouts designed for either part.

Q: How should I verify compatibility in my specific application?

A: Confirm that your circuit design requires 330 nH inductance, operates at or below 780 mA, and uses through-hole axial mounting. If these parameters match your application requirements, the substitute part is electrically and mechanically compatible.
