6000-222K-RC Equivalent & Substitute Parts

Part Overview

The Bourns 6000-222K-RC is a 2.2 mH unshielded drum core wirewound inductor rated for 360 mA with a maximum DC resistance of 5.9 Ohm. This through-hole radial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 6000-222K-RC carries a "Not For New Designs" product status, indicating it has been superseded in Bourns' current product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design continuity where this component specification remains functionally required.

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-222K-RC is determined by strict equivalence across the following critical parameters:

Inductance value: 2.2 mH with ±10% tolerance
Current rating: 360 mA minimum
DC resistance: 5.9 Ohm maximum
Core material and type: Ferrite drum core, unshielded
Mounting configuration: Through-hole radial, vertical cylinder
Physical footprint: 0.354" diameter, 0.480" maximum height
Electrical performance: Q factor and self-resonant frequency characteristics

The RLB9012-222KL meets all these criteria and is classified as a direct substitute. Both components share identical inductance, current rating, DC resistance, core construction, and physical dimensions. The substitute maintains functional and mechanical compatibility while offering improved product status and availability.

Engineering Selection Recommendations

The RLB9012-222KL is the direct substitute for the 6000-222K-RC based on complete electrical and mechanical parameter equivalence. Selection of the RLB9012-222KL is supported by the following factors:

Active product status ensures ongoing manufacturer support and supply chain availability
All critical electrical parameters match the original specification exactly
Physical dimensions and mounting configuration are identical, enabling direct PCB compatibility
Operating temperature range of -55°C to 125°C exceeds the original -55°C to 105°C specification, providing extended thermal margin
Both components maintain ROHS3 compliance and equivalent regulatory certifications
Packaging format differs (tray versus bulk), which may require adjustment to procurement and handling procedures but does not affect component functionality

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-222KL be used as a direct replacement for the 6000-222K-RC on existing PCBs?

A: Yes. Both components share identical physical dimensions (0.354" diameter, 0.480" height), mounting type (through-hole radial), and electrical specifications (2.2 mH, 360 mA, 5.9 Ohm DCR). No PCB modifications are required.

Q: What is the difference in operating temperature range between these parts?

A: The 6000-222K-RC operates from -55°C to 105°C, while the RLB9012-222KL operates from -55°C to 125°C. The substitute provides an additional 20°C of upper temperature margin, which is beneficial for thermal headroom in applications approaching the original specification limit.

Q: Are there packaging considerations when switching from 6000-222K-RC to RLB9012-222KL?

A: The primary packaging difference is format: the 6000-222K-RC is supplied in bulk packaging, while the RLB9012-222KL is supplied in tray packaging. This affects handling, storage, and procurement workflows but does not impact component performance or compatibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 6000-222K-RC and RLB9012-222KL are ROHS3 compliant, REACH unaffected, and classified under the same ECCN and HTSUS codes, ensuring equivalent regulatory status.

Q: Why is the 6000-222K-RC marked as "Not For New Designs"?

A: This designation indicates the part has been superseded in Bourns' active product line. The RLB9012-222KL represents the current active equivalent and is the recommended choice for new designs and ongoing production.
