IMS02ER101K Equivalent & Substitute Parts

Part Overview

The IMS02ER101K is a 100 µH shielded molded inductor manufactured by Vishay Dale, rated for 51 mA maximum current with 16.8Ohm DC resistance. This component is part of the IMS-2 series and is designed for through-hole axial mounting applications requiring shielded inductive filtering or energy storage.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or design requirements allow for alternative electrical characteristics within acceptable tolerance ranges.

Substitute Part Grouping Explanation

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

• Inductance Value: Both parts are rated at 100 µH, meeting the core functional requirement
• Mounting Type: Both are through-hole axial components, ensuring mechanical compatibility
• Package / Case: Both use axial packaging, compatible with existing PCB layouts
• Type: Both are molded inductors with ferrite cores

The 9230-68-RC differs in current rating (125 mA versus 51 mA) and DC resistance (8Ohm Max versus 16.8Ohm Max). These differences represent improved electrical performance characteristics that remain compatible with applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The 9230-68-RC is suitable as a substitute when the following conditions are met:

• The application current requirement does not exceed 51 mA (the lower rating of the original part)
• Electromagnetic shielding is not a critical design requirement, as the substitute is unshielded
• Operating temperature range of -55°C to 125°C is acceptable for the application
• ROHS3 compliance is required or acceptable for the end product

The substitute part provides lower DC resistance (8Ohm versus 16.8Ohm), which reduces power dissipation and heat generation in the inductor. This represents an improvement over the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 9230-68-RC replace the IMS02ER101K in all applications?

A: No. The primary limitation is shielding. The IMS02ER101K is shielded while the 9230-68-RC is unshielded. Applications requiring electromagnetic isolation or operating in noise-sensitive environments may not tolerate the unshielded substitute.

Q: What is the significance of the current rating difference (51 mA vs. 125 mA)?

A: The substitute part has a higher current rating, meaning it can safely handle greater current without saturation. For applications operating at or below 51 mA, this difference is not a limiting factor. The substitute will perform identically or better in this regard.

Q: Does the lower DC resistance of the substitute part affect circuit performance?

A: Lower DC resistance reduces resistive losses in the inductor. For most applications, this is beneficial as it decreases power dissipation and heat generation. However, if the circuit design relies on the specific impedance characteristics of the original part, substitution should be evaluated in the complete circuit context.

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

A: Yes. Both parts are through-hole axial components with the same package type, ensuring mechanical and footprint compatibility.

Q: What compliance certifications does each part carry?

A: The 9230-68-RC is ROHS3 compliant and REACH unaffected. Compliance information for the IMS02ER101K is not provided in the available specifications.
