IM02ER101K Equivalent & Substitute Parts

Part Overview

The IM02ER101K is a 100 µH unshielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring fixed inductance with a current rating of 84 mA and maximum DC resistance of 8 Ohm. This component is part of the IM series and is currently in stock with 740 pieces available.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements allow for compatible alternatives with enhanced electrical performance characteristics within the same parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

The 9230-68-RC from Bourns Inc. qualifies as a direct substitute based on the following critical parameters:

• Inductance Value: Both parts specify 100 µH, ensuring identical inductive performance
• DC Resistance: Both maintain 8 Ohm maximum, preserving circuit impedance characteristics
• Shielding Configuration: Both are unshielded molded inductors
• Mounting Architecture: Both utilize through-hole axial mounting
• Core Material: Both employ ferrite core construction

The substitute part demonstrates enhanced current rating capability (125 mA versus 84 mA), providing additional design margin without compromising compatibility. This increased current capacity allows the substitute to operate safely in applications where the original part meets minimum requirements.

Parameter Comparison

Engineering Selection Recommendations

The 9230-68-RC is suitable as a direct replacement for the IM02ER101K in applications where the following conditions are met:

• Circuit current requirements do not exceed 125 mA
• Axial through-hole mounting footprint compatibility is confirmed
• Operating temperature range of -55°C to 125°C is acceptable for the application
• RoHS3 compliance is required or preferred for the end product

The substitute part's higher current rating provides additional operational headroom without introducing incompatibility. Both components maintain identical inductance and DC resistance specifications, ensuring equivalent electrical performance in the circuit.

Frequently Asked Questions (FAQ)

Q: Can the 9230-68-RC replace the IM02ER101K in any application?
