Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6000-271K-RC is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 270 µH with ±10% tolerance
• Current rating: 900 mA minimum
• DC resistance: 750mOhm maximum
• Core material and shielding: Ferrite, unshielded
• Package type: Radial, vertical cylinder through-hole
• Physical footprint: 0.354" diameter, 0.480" maximum height
• Q factor and self-resonant frequency characteristics

The RLB9012-271KL meets all these criteria and qualifies as a direct electrical and mechanical substitute. Both components are manufactured by Bourns Inc. and share identical inductance, current rating, DC resistance, core construction, and physical dimensions.

Parameter Comparison

*The RLB9012-271KL supports an extended upper operating temperature of 125°C versus 105°C for the 6000-271K-RC, providing broader thermal margin.

Engineering Selection Recommendations

The RLB9012-271KL is the direct substitute for the 6000-271K-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is product lifecycle status: the 6000-271K-RC is designated "Not For New Designs," while the RLB9012-271KL maintains "Active" status within Bourns' current product line. For applications requiring component replacement or procurement, the RLB9012-271KL is the recommended selection, as it ensures ongoing manufacturer support, availability, and compliance with evolving industry standards.

The RLB9012-271KL's extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) provides additional thermal headroom for demanding applications without compromising any electrical or mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-271KL be used as a direct replacement for the 6000-271K-RC in existing designs?

A: Yes. Both inductors are electrically and mechanically identical across all critical parameters: 270 µH inductance, 900 mA current rating, 750mOhm maximum DC resistance, ferrite unshielded drum core construction, and identical physical dimensions. Pin-for-pin and footprint compatibility is confirmed.

Q: What is the difference between the 6000 and RLB9012 series?

A: The 6000-271K-RC belongs to Bourns' legacy 6000 series and carries "Not For New Designs" status. The RLB9012-271KL is part of the current RLB9012 series with active product status. Both share identical electrical and mechanical specifications for this 270 µH, 900 mA inductor.

Q: Does the packaging difference (Bulk vs. Tray) affect electrical performance?

A: No. Packaging format (Bulk for 6000-271K-RC, Tray for RLB9012-271KL) is a logistics and handling consideration only. It does not affect component electrical characteristics, performance, or reliability.

Q: Is the RLB9012-271KL suitable for high-temperature applications?

A: The RLB9012-271KL operates across -55°C to 125°C, providing a 20°C higher upper temperature limit than the 6000-271K-RC (-55°C to 105°C). This extended range makes it suitable for applications requiring elevated thermal performance.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the 6000-271K-RC and RLB9012-271KL are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inductance frequency test difference between these parts?

A: The 6000-271K-RC is tested at 796 kHz, while the RLB9012-271KL is tested at 1 kHz. Both achieve the specified 270 µH inductance value and 20 Q factor at their respective test frequencies. This difference reflects measurement methodology and does not affect functional equivalence.
