Key Parameters

Substitute Part Grouping Explanation

The Bourns RLB9012-470KL qualifies as a direct substitute for the 6000-470K-RC based on the following critical parameters:

• Identical inductance value: 47 µH with ±10% tolerance
• Matching current rating: 1.77 A
• Identical DC resistance specification: 160 mOhm maximum
• Same core material: Ferrite
• Identical shielding configuration: Unshielded
• Matching physical dimensions: 0.354" diameter, 0.480" height
• Identical mounting type: Through hole, radial vertical cylinder package
• Equivalent electrical performance: Q factor of 30 @ 2.52 MHz, self resonant frequency of 6.5 MHz

The primary distinction is product status: the RLB9012-470KL is an active component, whereas the 6000-470K-RC is designated as not for new designs.

Engineering Selection Recommendations

The RLB9012-470KL is the direct active equivalent for the 6000-470K-RC. All critical electrical and mechanical parameters are identical, ensuring pin-for-pin and form-factor compatibility. The RLB9012-470KL carries active product status with full ROHS3 and REACH compliance, making it suitable for new designs and ongoing production applications where the 6000 series is no longer recommended.

The extended operating temperature range of the RLB9012-470KL (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin for applications operating at elevated temperatures. Both components are manufactured by Bourns Inc. and share identical packaging specifications, allowing direct substitution without circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-470KL be used as a direct replacement for the 6000-470K-RC?

A: Yes. The RLB9012-470KL is electrically and mechanically identical to the 6000-470K-RC across all specified parameters, including inductance, current rating, DC resistance, core material, shielding, physical dimensions, and mounting configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between these two parts?

A: The primary differences are product status and packaging format. The 6000-470K-RC is designated as not for new designs and supplied in bulk packaging. The RLB9012-470KL is an active component supplied in tray packaging. The RLB9012-470KL also supports an extended upper operating temperature of 125°C compared to 105°C for the 6000-470K-RC.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. Compliance status is equivalent between the two components.

Q: Will the RLB9012-470KL fit the same PCB footprint?

A: Yes. Both components share identical physical dimensions (0.354" diameter, 0.480" height) and radial vertical cylinder package configuration, ensuring compatibility with existing through-hole PCB layouts.

Q: Which part should be selected for new designs?

A: The RLB9012-470KL should be selected for new designs. The 6000-470K-RC is not recommended for new applications due to its discontinued design status.
