6000-331K-RC Equivalent & Substitute Parts

Part Overview

The 6000-331K-RC is a 330 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 780 mA with a maximum DC resistance of 850mOhm. This through-hole component features a radial, vertical cylinder package and operates across the temperature range of -55°C to 105°C.

The 6000-331K-RC carries a "Not For New Designs" product status, indicating it has been superseded in Bourns' product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this inductor specification remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-331K-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 330 µH
• Inductance tolerance: ±10%
• Current rating: 780 mA minimum
• DC resistance: 850mOhm maximum
• Core material and shielding: Ferrite, unshielded
• Package type: Radial, vertical cylinder through-hole
• Physical dimensions: 0.354" diameter, 0.480" maximum height
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The RLB9012-331KL meets all substitution criteria. It maintains identical electrical specifications, physical form factor, and compliance status while offering improved product lifecycle status (Active vs. Not For New Designs).

Parameter Comparison

Engineering Selection Recommendations

The RLB9012-331KL is the direct substitute for the 6000-331K-RC. Both components are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. The RLB9012-331KL carries Active product status, making it the recommended choice for new procurement and ongoing production support.

The RLB9012-331KL provides an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), offering additional thermal margin in applications requiring higher temperature operation. All electrical parameters, physical dimensions, and mechanical compatibility remain identical, ensuring direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-331KL be used as a direct replacement for the 6000-331K-RC?

A: Yes. Both components share identical inductance (330 µH), current rating (780 mA), DC resistance (850mOhm maximum), core type (ferrite, unshielded), and physical dimensions (0.354" diameter, 0.480" height). Through-hole mounting and radial vertical cylinder packaging are identical. No circuit modifications are required.

Q: What is the difference in packaging between these parts?

A: The 6000-331K-RC is supplied in bulk packaging, while the RLB9012-331KL is supplied in tray packaging. Both are through-hole components with identical form factors and mounting compatibility.

Q: Does the extended temperature range of the RLB9012-331KL affect compatibility?

A: No. The RLB9012-331KL operates from -55°C to 125°C, compared to the 6000-331K-RC range of -55°C to 105°C. The extended upper temperature limit provides additional operational margin and does not impact compatibility in applications using the original temperature specification.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 6000-331K-RC and RLB9012-331KL are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the 6000-331K-RC marked "Not For New Designs"?

A: This designation indicates the part has been superseded in Bourns' active product line. The RLB9012-331KL is the current equivalent offering identical specifications with Active product status, making it the appropriate choice for new applications and ongoing production.
