IMS05WDSTR82K40 Equivalent & Substitute Parts

Part Overview

The IMS05WDSTR82K40 is a 820 nH shielded inductor manufactured by Vishay Dale, designed for through-hole applications requiring compact form factor and controlled DC resistance characteristics. This component is specified for 870 mA maximum current handling with 460 mOhm maximum DC resistance in the IMS-5WD-40 series. The part remains in active production with 851 pieces available in new original stock condition.

Substitute parts are identified when equivalent inductance values, current ratings, and DC resistance specifications align within acceptable engineering tolerances for the IMS series product family, enabling component interchangeability in circuit designs where form factor or performance characteristics may require alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the IMS05WDSTR82K40 is based on the following critical parameters:

• Inductance Value: 820 nH (exact match required)
• Current Rating: Minimum 600 mA acceptable; original specification 870 mA
• DC Resistance: Maximum 590 mOhm acceptable; original specification 460 mOhm
• Configuration: Shielded inductor, through-hole axial mounting
• Manufacturer: Vishay Dale IMS series family

The IMS5SWDBHR82K65 qualifies as a substitute part within the same manufacturer family, maintaining identical inductance while operating within acceptable current and resistance parameters for applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Selection between IMS05WDSTR82K40 and IMS5SWDBHR82K65 depends on circuit current requirements and DC resistance tolerance specifications:

• Primary Selection: IMS05WDSTR82K40 when circuit design requires 870 mA current capacity and 460 mOhm maximum DC resistance specification.
• Substitute Selection: IMS5SWDBHR82K65 when circuit application operates at or below 600 mA and can accommodate 590 mOhm maximum DC resistance. The molded construction variant provides equivalent inductance performance within these electrical constraints.

Both components are manufactured by Vishay Dale within the IMS shielded inductor family and maintain identical 820 nH inductance specification, ensuring functional equivalence for inductance-critical circuit applications.

Frequently Asked Questions (FAQ)

Q: Can IMS5SWDBHR82K65 replace IMS05WDSTR82K40 in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 600 mA and the application can tolerate 590 mOhm DC resistance. If the design requires the full 870 mA current rating or specifies 460 mOhm maximum resistance, the original IMS05WDSTR82K40 must be used.

Q: What is the difference between the IMS-5WD-40 and IMS-5SWD-65 series designations?

A: Series designations indicate different construction and performance characteristics within the Vishay Dale IMS family. The IMS-5WD-40 represents the standard shielded configuration, while IMS-5SWD-65 indicates a molded shielded variant with different electrical performance parameters.

Q: Are both parts through-hole mounted?

A: Yes, both IMS05WDSTR82K40 and IMS5SWDBHR82K65 are configured for through-hole axial mounting on printed circuit boards.

Q: What happens if I use the substitute part in a circuit designed for 870 mA operation?

A: The IMS5SWDBHR82K65 is rated for 600 mA maximum current. Operating above this rating may cause component degradation or failure. Use only when circuit current requirements are confirmed at or below 600 mA.
