Substitute Part Grouping Explanation

Substitution of the 6000-220K-RC is determined by strict equivalence across the following electrical and mechanical parameters:

Inductance value: 22 µH ±10%
Current rating: 2.4 A minimum
DC resistance: 70 mOhm maximum
Core material and shielding: Ferrite, unshielded
Package type: Radial, vertical cylinder through-hole
Physical dimensions: 0.354" diameter, 0.480" maximum seated height
Operating temperature range: Minimum -55°C to 105°C

The RLB9012-220KL meets all electrical specifications and physical constraints required for direct substitution. The primary distinction is product status: the 6000-220K-RC is obsolete for new designs, while the RLB9012-220KL maintains active production status.

Engineering Selection Recommendations

The RLB9012-220KL is the direct equivalent for the 6000-220K-RC. Both components are manufactured by Bourns Inc. and maintain identical electrical and mechanical specifications. The RLB9012-220KL offers the advantage of active product status, ensuring continued availability and supply chain reliability. The extended operating temperature range of the RLB9012-220KL (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin without compromising performance in standard applications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-220KL directly replace the 6000-220K-RC in existing designs?

A: Yes. The RLB9012-220KL is electrically and mechanically equivalent. All critical parameters—inductance, current rating, DC resistance, core type, and physical dimensions—are identical. The component will function identically in the same circuit board layout and application.

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

A: The 6000-220K-RC is supplied in bulk packaging, while the RLB9012-220KL is supplied in tray packaging. Both use identical through-hole radial, vertical cylinder packages suitable for standard PCB assembly processes.

Q: Why is the 6000-220K-RC marked "Not For New Designs"?

A: This designation indicates the part is obsolete and no longer recommended for new product development. The RLB9012-220KL is the active equivalent and should be used for all new designs and ongoing production.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. There are no differences in regulatory certifications or environmental compliance.

Q: Does the extended temperature range of the RLB9012-220KL affect compatibility?

A: No. The RLB9012-220KL's extended operating range (-55°C to 125°C) is a superset of the 6000-220K-RC specification (-55°C to 105°C). This provides additional thermal margin and does not impact compatibility in applications within the original temperature range.

Q: What is the inventory status for these parts?

A: The 6000-220K-RC has 1065 pieces in stock. The RLB9012-220KL has 1730 pieces in stock, providing greater availability for production requirements.
