IM02ER100K Equivalent & Substitute Parts

Part Overview

The IM02ER100K is a 10 µH unshielded molded inductor manufactured by Vishay Dale, rated for 130 mA maximum current with 3.7Ohm DC resistance. This through-hole axial component is designed for general-purpose filtering and energy storage applications in electronic circuits. The part is currently in stock with 1,093 units available as new original inventory.

Equivalent parts are necessary when the primary manufacturer's stock is depleted, when supply chain constraints affect availability, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IM02ER100K is determined by the following critical parameters:

• Inductance Value: Must be 10 µH
• DC Resistance: Must not exceed 3.7Ohm maximum
• Current Rating: Must be equal to or greater than 130 mA
• Core Material: Ferrite (unshielded molded construction)
• Mounting Type: Through hole axial configuration
• Package Type: Axial lead spacing and dimensions

The substitute part 9230-44-RC from Bourns Inc. meets all substitution criteria. It maintains the same inductance value, DC resistance specification, and core material while providing a higher current rating of 180 mA, which exceeds the minimum requirement of 130 mA.

Parameter Comparison

Engineering Selection Recommendations

The 9230-44-RC from Bourns Inc. is a qualified substitute for the IM02ER100K. Selection between these parts should be based on:

Product Status: The 9230-44-RC is listed as Active, ensuring continued availability and manufacturer support.

Compliance Certifications: The 9230-44-RC carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Current Rating Margin: The substitute part provides a 50 mA higher current rating (180 mA vs. 130 mA), offering additional operational margin in applications where the IM02ER100K is specified.

Electrical Equivalence: Identical inductance value, DC resistance, and core material ensure direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 9230-44-RC be used as a direct replacement for the IM02ER100K in existing designs?

A: Yes. Both parts share identical inductance (10 µH), DC resistance (3.7Ohm maximum), core material (ferrite), and axial through-hole package configuration. The higher current rating of the substitute part does not create compatibility issues.

Q: What is the significance of the higher current rating on the 9230-44-RC?

A: The 9230-44-RC is rated for 180 mA compared to the IM02ER100K's 130 mA. This provides additional operational headroom and does not affect substitution eligibility. The part will function correctly in circuits designed for the lower-rated component.

Q: Are there dimensional differences between these parts?

A: The 9230-44-RC has specified dimensions of 0.095" diameter × 0.250" length (2.41mm × 6.35mm). The IM02ER100K dimensions are not provided in the available data. Verify physical fit in your specific PCB layout before final assembly.

Q: What compliance standards apply to the substitute part?

A: The 9230-44-RC is ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components in most markets.

Q: Are there packaging differences between the main part and substitute?

A: The IM02ER100K is specified with "-" packaging notation. The 9230-44-RC is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.
