Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IM02ER120K is determined by the following critical parameters:

• Inductance Value: Must be 12 µH (±10% tolerance acceptable)
• DC Resistance: Must not exceed 2.7Ohm
• Current Rating: Must be equal to or greater than 155 mA
• Mounting Type: Must be Through Hole
• Package / Case: Must be Axial
• Core Material: Ferrite construction
• Shielding: Unshielded configuration

The substitute part 9230-46-RC from Bourns Inc. meets all substitution criteria with identical inductance, DC resistance, and package specifications, while providing a higher current rating of 210 mA.

• Packaging: Both parts are supplied in axial through-hole format with identical mechanical dimensions (0.095" Dia x 0.250" L)

Frequently Asked Questions (FAQ)

Q: Can the 9230-46-RC replace the IM02ER120K in existing designs?

A: Yes. Both inductors share identical inductance (12 µH), DC resistance (2.7Ohm Max), and axial through-hole package specifications. The 9230-46-RC's higher current rating (210 mA vs. 155 mA) makes it a direct substitute with no circuit modifications required.

Q: What are the key parameters that determine substitution compatibility?

A: Inductance value, DC resistance, current rating, mounting type, and package format are the primary criteria. Both parts match on inductance, DC resistance, and package specifications. The 9230-46-RC exceeds the current rating requirement.

Q: Are there any compliance or certification differences?

A: The 9230-46-RC is documented as ROHS3 compliant and REACH unaffected. Compliance documentation for the IM02ER120K was not provided in the reference data. Verify compliance requirements for your specific application.

Q: What is the physical size compatibility?

A: Both parts are axial through-hole components. The 9230-46-RC dimensions are specified as 0.095" Dia x 0.250" L (2.41mm x 6.35mm), ensuring compatibility with standard PCB layouts designed for the IM02ER120K.

Q: Can I use the 9230-46-RC in high-temperature applications?

A: The 9230-46-RC operates across -55°C to 125°C. Verify that your application requirements fall within this temperature range before selection.
