Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IM02ER4R7K are qualified based on the following electrical and mechanical parameters:

• Inductance Value: 4.7 µH (exact match required)
• DC Resistance: 1.2Ohm Max (maximum allowable value)
• Current Rating: Equal to or greater than 230 mA
• Mounting Type: Through Hole
• Package / Case: Axial
• Shielding Type: Unshielded

The substitute part 9230-36-RC from Bourns Inc. meets all substitution criteria with a current rating of 320 mA, which exceeds the minimum requirement, providing additional design margin.

Parameter Comparison

Engineering Selection Recommendations

The 9230-36-RC from Bourns Inc. is a direct electrical and mechanical substitute for the IM02ER4R7K. The substitute part provides identical inductance and DC resistance specifications while offering a higher current rating of 320 mA compared to the original 230 mA specification. This increased current capacity provides additional operational margin without affecting circuit performance.

Both parts are through-hole axial components with unshielded molded construction, ensuring identical PCB footprint and mounting compatibility. The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the 9230-36-RC be used as a direct replacement for the IM02ER4R7K?

A: Yes. Both parts have identical inductance (4.7 µH), DC resistance (1.2Ohm Max), mounting type (through hole), and package configuration (axial). The substitute part's higher current rating (320 mA vs. 230 mA) does not affect compatibility.

Q: What is the significance of the higher current rating on the substitute part?

A: The 9230-36-RC is rated for 320 mA compared to the IM02ER4R7K's 230 mA. This higher rating provides additional design margin and allows the component to operate safely in applications requiring higher current levels without saturation or thermal stress.

Q: Are there any physical dimension differences between these parts?

A: The 9230-36-RC has specified dimensions of 0.095" Dia x 0.250" L (2.41mm x 6.35mm). Physical dimensions for the IM02ER4R7K are not provided in the available data. Verify mechanical compatibility with your PCB layout before substitution.

Q: What compliance certifications apply to the substitute part?

A: The 9230-36-RC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Are there additional substitute options available?

A: The 9230-36-RC has documented substitutes including 1025-36K and 1025R-36K. Consult the Bourns Inc. product documentation for compatibility details on these alternatives.
