Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IM02ER6R8K is determined by the following critical parameters:

• Inductance Value: 6.8 µH (exact match required)
• DC Resistance: 2Ohm maximum (equal or lower acceptable)
• Mounting Type: Through hole axial configuration
• Shielding Type: Unshielded molded construction
• Package Compatibility: Axial lead spacing and dimensions

The Bourns Inc. 9230-40-RC meets all substitution criteria. This part maintains the identical inductance specification and DC resistance rating while providing a higher current rating of 245 mA, making it suitable for applications where the IM02ER6R8K operates below its maximum current capacity.

Parameter Comparison

Engineering Selection Recommendations

The Bourns Inc. 9230-40-RC is a direct electrical and mechanical substitute for the IM02ER6R8K. Both components share identical inductance and DC resistance specifications with axial through-hole mounting configuration.

The 9230-40-RC offers the following advantages:

• Higher Current Rating: 245 mA versus 175 mA provides 40% additional current capacity
• Compliance Certification: ROHS3 compliant and REACH unaffected status documented
• Active Product Status: Bourns 9230 series remains in active production
• Established Specifications: Complete electrical characterization including Q factor, self-resonant frequency, and operating temperature range

Selection between these parts depends on application current requirements. For circuits operating at or near 175 mA, the 9230-40-RC provides improved thermal margin and reliability. Both parts are suitable for identical PCB footprints and lead spacing.

Frequently Asked Questions (FAQ)

Q: Can the 9230-40-RC replace the IM02ER6R8K in existing designs?

A: Yes. Both inductors share identical inductance (6.8 µH) and DC resistance (2Ohm maximum) specifications. The axial through-hole package and lead configuration are compatible. The 9230-40-RC accommodates higher current levels, making it suitable for direct substitution.

Q: What is the significance of the higher current rating on the 9230-40-RC?

A: The 9230-40-RC is rated for 245 mA compared to the IM02ER6R8K at 175 mA. This 40% increase in current capacity reduces thermal stress in the component during operation, extending component life and improving circuit reliability when operating near maximum current specifications.

Q: Are there physical dimension differences between these parts?

A: The 9230-40-RC dimensions are specified as 0.095" diameter × 0.250" length (2.41mm × 6.35mm). The IM02ER6R8K dimensions are not provided in the available data. Verification of physical compatibility with existing PCB layouts is recommended before implementation.

Q: What compliance certifications apply to the 9230-40-RC?

A: The Bourns 9230-40-RC is ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.8000.

Q: Is tolerance specification important for substitution?

A: The 9230-40-RC carries ±10% inductance tolerance. The IM02ER6R8K tolerance is not specified in available documentation. For applications with strict inductance tolerance requirements, both parts should be evaluated against circuit specifications.
