Substitute Part Grouping Explanation

Substitute parts for the IMS05WDRUR82K40 are identified based on matching or exceeding the following critical parameters:

• Inductance Value: 820 nH (exact match required)
• Current Rating: Minimum 870 mA (equal or higher acceptable)
• DC Resistance: Maximum 460 mOhm (lower values acceptable)
• Package Type: Through-hole axial configuration
• Shielding: Shielded construction
• Manufacturer: Vishay Dale (same manufacturer ensures design compatibility)

The substitute part IMS5SWDBHR82K65 meets these criteria with equivalent inductance and shielding while operating at a reduced current rating of 600 mA. This part is suitable for applications where the full 870 mA rating is not required.

Parameter Comparison

Engineering Selection Recommendations

The IMS05WDRUR82K40 remains the primary choice for applications requiring the full 870 mA current rating with 460 mOhm maximum DC resistance. The substitute part IMS5SWDBHR82K65 is applicable only in circuits where the maximum current demand does not exceed 600 mA. Both parts maintain identical inductance values and shielded construction, ensuring equivalent electromagnetic performance in filtering and energy storage applications. Selection between these parts should be determined by the actual current requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can IMS5SWDBHR82K65 replace IMS05WDRUR82K40 in all applications?

A: No. The substitute part is rated for 600 mA maximum current, compared to 870 mA for the main part. Substitution is valid only when the application current requirement does not exceed 600 mA.

Q: Are the inductance values identical between these parts?

A: Yes. Both parts provide 820 nH inductance and are suitable for equivalent filtering and energy storage functions.

Q: What is the difference in DC resistance between these parts?

A: The main part IMS05WDRUR82K40 has a maximum DC resistance of 460 mOhm, while the substitute IMS5SWDBHR82K65 has a maximum of 590 mOhm. The higher resistance in the substitute part may result in increased power dissipation in high-current applications.

Q: Are both parts through-hole components?

A: Yes. Both parts are through-hole axial inductors suitable for PCB mounting in applications requiring traditional lead-based assembly.

Q: What does "shielded molded" mean for the substitute part?

A: Shielded molded construction provides electromagnetic shielding through a molded encapsulation process, reducing radiated emissions and susceptibility to external magnetic fields compared to standard shielded designs.
