6000-473K-RC Equivalent & Substitute Parts

Part Overview

The Bourns 6000-473K-RC is a 47 mH unshielded drum core wirewound inductor rated for 80 mA with a maximum DC resistance of 137.8 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The 6000-473K-RC carries a "Not For New Designs" product status, indicating it has been superseded in Bourns' product portfolio. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and transition to actively supported alternatives where applicable.

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-473K-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 47 mH with ±10% tolerance
• Current rating: 80 mA minimum
• DC resistance: 137.8 Ohm maximum
• Core material and type: Ferrite drum core, unshielded
• Mounting configuration: Through-hole radial, vertical cylinder
• Physical envelope: 0.354" diameter, 0.480" maximum height
• Electrical performance: Q factor and self-resonant frequency characteristics

The RLB9012-473KL meets all substitution criteria. Both parts share identical electrical specifications, core construction, and mechanical form factor. The primary distinction is product lifecycle status and packaging format.

Parameter Comparison

*RLB9012-473KL supports extended upper temperature limit of 125°C versus 105°C for 6000-473K-RC, providing additional thermal margin.

Engineering Selection Recommendations

The RLB9012-473KL is a direct electrical and mechanical equivalent to the 6000-473K-RC. Selection between these parts should be based on the following factors:

Product Lifecycle: The RLB9012-473KL carries Active product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. The 6000-473K-RC is designated "Not For New Designs," signaling end-of-life status.

Compliance & Certifications: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Thermal Performance: The RLB9012-473KL extends the maximum operating temperature to 125°C compared to 105°C for the 6000-473K-RC. This provides additional design margin for applications operating at elevated ambient or self-heating conditions.

Packaging Considerations: The 6000-473K-RC is supplied in bulk packaging, while the RLB9012-473KL is supplied in tray format. Packaging selection depends on procurement volume and handling requirements.

For new designs or redesigns, the RLB9012-473KL is the recommended selection. For existing production using the 6000-473K-RC, the RLB9012-473KL provides a seamless drop-in replacement with enhanced lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-473KL replace the 6000-473K-RC in existing applications?

A: Yes. The RLB9012-473KL is electrically and mechanically equivalent. All critical parameters—inductance, current rating, DC resistance, core type, and physical dimensions—are identical. The component can be substituted without circuit redesign or PCB layout modification.

Q: What is the significance of the "Not For New Designs" status on the 6000-473K-RC?

A: This designation indicates the part has been superseded in the manufacturer's product portfolio. While existing inventory may remain available, the manufacturer does not recommend its use in new designs. The RLB9012-473KL is the active equivalent.

Q: Are there differences in electrical performance between these parts?

A: No. Both parts exhibit identical inductance (47 mH), current rating (80 mA), DC resistance (137.8 Ohm max), Q factor (15 @ 79kHz), and self-resonant frequency (120kHz). Electrical behavior in circuit operation is equivalent.

Q: How do the operating temperature ranges differ?

A: The 6000-473K-RC operates from -55°C to 105°C. The RLB9012-473KL extends the upper limit to 125°C. For applications operating near or above 105°C, the RLB9012-473KL provides additional thermal margin.

Q: Does packaging format affect component performance?

A: No. The 6000-473K-RC (bulk packaging) and RLB9012-473KL (tray packaging) are functionally identical. Packaging format is a logistics and handling consideration, not a performance factor. Selection depends on procurement volume and assembly process requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 6000-473K-RC and RLB9012-473KL are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations for electronic components.
