IMS02WWDBHR82K40 Equivalent & Substitute Parts

Part Overview

The IMS02WWDBHR82K40 is a 820 nH shielded wirewound inductor manufactured by Vishay Dale, rated for 720 mA maximum current with a DC resistance of 638 mOhm maximum. This axial through-hole component is designed for applications requiring compact, shielded inductance in the sub-microhenry range. Substitute parts are identified based on matching inductance value, shielding characteristics, and compatible current ratings within the IMS series product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMS02WWDBHR82K40 is determined by the following criteria:

• Inductance value must be 820 nH
• Shielding requirement must be maintained
• Current rating must be equal to or greater than 720 mA
• DC resistance must not exceed 638 mOhm
• Package must be through-hole axial configuration
• Component must be from the Vishay Dale IMS inductor family

The identified substitute part meets the inductance specification while offering alternative construction (molded vs. wirewound) within the same electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

The IMS5SWDBHR82K65 substitute part maintains identical inductance specification and provides lower DC resistance (590 mOhm vs. 638 mOhm). However, the current rating is reduced to 600 mA compared to the main part's 720 mA rating. Selection between these parts must be based on the actual current requirements of the application. If circuit current demand does not exceed 600 mA, the substitute part offers improved resistance characteristics. If application current exceeds 600 mA, the main part IMS02WWDBHR82K40 is required.

Frequently Asked Questions (FAQ)

Q: Can IMS5SWDBHR82K65 be used as a direct replacement for IMS02WWDBHR82K40?

A: Direct replacement is possible only if the application current requirement does not exceed 600 mA. The substitute part has a lower current rating (600 mA vs. 720 mA) despite matching inductance and offering superior DC resistance characteristics.

Q: What is the difference between wirewound and molded construction in these inductors?

A: Both construction types provide shielding and maintain the same 820 nH inductance specification. The wirewound version (IMS02WWDBHR82K40) supports higher current capacity, while the molded version (IMS5SWDBHR82K65) offers lower DC resistance and different mechanical properties.

Q: Are both parts compatible with the same PCB footprint?

A: Both parts are through-hole axial components. Physical compatibility depends on specific board layout dimensions. Consult the respective datasheets for exact lead spacing and body dimensions.

Q: Which part should be selected for new designs?

A: Selection depends on circuit current requirements. For applications requiring 600 mA or less, either part is suitable, with the substitute offering lower resistance. For applications requiring current above 600 mA, the main part is mandatory.
