Key Parameters

Substitute Part Grouping Explanation

The Bourns RLB9012-390KL qualifies as a direct substitute for the 6000-390K-RC based on the following critical parameters:

• Inductance Value: Both parts specify 39 µH with ±10% tolerance
• Current Rating: Both rated for 1.85 A maximum
• DC Resistance: Both maintain 100 mOhm maximum
• Core Type: Both utilize ferrite drum core construction
• Shielding Configuration: Both are unshielded
• Mounting & Package: Both feature through-hole radial, vertical cylinder mounting with identical physical dimensions (0.354" diameter, 0.480" height)
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary distinction is product status: the RLB9012-390KL is an active component, whereas the 6000-390K-RC is designated "Not For New Designs."
