Substitute Part Grouping Explanation
Substitution of the Bourns 6000-331K is determined by strict equivalence across the following electrical and mechanical parameters:
- Inductance value: 330 µH with ±10% tolerance
- Current rating: 780 mA minimum
- DC resistance: 850 mOhm maximum
- Core type: Ferrite, unshielded drum core
- Frequency characteristics: Q @ 796 kHz and self-resonant frequency
- Operating temperature range: -55°C to 105°C
- Mounting configuration: Through-hole radial, vertical cylinder
- Physical dimensions: 0.354" diameter and 0.480" maximum seated height
The substitute part 6000-331K-RC meets all these criteria and is manufactured by the same supplier (Bourns Inc.) within the same product series.

Engineering Selection Recommendations
The 6000-331K-RC serves as the direct functional equivalent to the obsolete 6000-331K. Both parts maintain identical electrical specifications and physical dimensions, ensuring direct substitution in existing circuit designs without layout modifications.
The primary distinction between the two parts is regulatory compliance. The 6000-331K-RC achieves ROHS3 compliance, whereas the original 6000-331K is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with current environmental standards, the 6000-331K-RC is the appropriate selection.
The 6000-331K-RC carries a product status of "Not For New Designs," indicating limited long-term availability. For new product development requiring extended component lifecycle, further investigation into alternative inductors within the Bourns 6000 series or equivalent product lines may be warranted.
Frequently Asked Questions (FAQ)
Q: Can the 6000-331K-RC be used as a direct replacement for the 6000-331K?
A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including inductance, current rating, DC resistance, frequency characteristics, operating temperature range, and physical dimensions. No circuit modifications are required.
Q: What is the difference between the 6000-331K and 6000-331K-RC?
A: The parts are functionally equivalent. The primary difference is packaging and regulatory compliance. The 6000-331K-RC is supplied in bulk packaging and meets ROHS3 compliance standards, whereas the 6000-331K is RoHS non-compliant.
Q: Why is the 6000-331K marked as obsolete?
A: The 6000-331K has been discontinued by the manufacturer. The 6000-331K-RC represents the current production equivalent and should be used for all new procurement and design activities.
Q: Are there any performance differences between these parts?
A: No. Both parts deliver identical electrical performance across all measured parameters: 330 µH inductance, 780 mA current rating, 850 mOhm maximum DC resistance, Q factor of 20 at 796 kHz, and 2.3 MHz self-resonant frequency.
Q: What is the physical compatibility of these parts?
A: Both parts use identical through-hole radial, vertical cylinder packaging with 0.354" diameter and 0.480" maximum seated height. PCB footprints and mounting configurations are interchangeable.
Q: Does the ROHS3 compliance of the 6000-331K-RC affect circuit performance?
A: No. RoHS compliance relates to material composition and environmental standards, not electrical or mechanical performance. The 6000-331K-RC maintains all electrical specifications of the original part.
