6000-221K-RC Equivalent & Substitute Parts

Part Overview

The 6000-221K-RC is a 220 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1 A continuous current with a maximum DC resistance of 650 mOhm. This through-hole component is designed for radial, vertical cylinder mounting in applications requiring fixed inductance values with ferrite core construction.

The 6000-221K-RC carries a "Not For New Designs" product status, indicating it has been superseded in Bourns' product line. Identifying equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this inductance value and current rating remain functionally required.

Substitute Part Grouping Explanation

Substitution of the 6000-221K-RC is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance Value: 220 µH (±10% tolerance)
• Current Rating: 1 A minimum continuous rating
• DC Resistance: 650 mOhm maximum
• Core Type: Ferrite, unshielded drum core construction
• Mounting Configuration: Through-hole, radial vertical cylinder orientation
• Physical Envelope: 0.354" diameter, 0.480" maximum seated height
• RoHS Compliance: ROHS3 Compliant status required

The RLB9012-221KL meets all specified electrical and mechanical criteria, providing direct functional equivalence for applications currently using the 6000-221K-RC.

Parameter Comparison

Engineering Selection Recommendations

The RLB9012-221KL is the direct equivalent substitute for the 6000-221K-RC. Both components are manufactured by Bourns Inc. and share identical electrical specifications and physical dimensions.

The primary distinction is product lifecycle status: the 6000-221K-RC is designated "Not For New Designs," while the RLB9012-221KL maintains "Active" status. This indicates the RLB9012-221KL is the current production equivalent and recommended for all new applications and ongoing procurement.

Both parts maintain ROHS3 compliance and are suitable for applications requiring 220 µH inductance at 1 A continuous current with ferrite core construction. The RLB9012-221KL provides an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), offering additional thermal margin in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-221KL be used as a direct replacement for the 6000-221K-RC in existing designs?

A: Yes. Both components share identical inductance values, current ratings, DC resistance specifications, core materials, shielding characteristics, and physical dimensions. Pin-to-pin and footprint compatibility is assured for through-hole mounting applications.

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

A: The 6000-221K-RC is supplied in bulk packaging, while the RLB9012-221KL is supplied in tray packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance.

Q: Why does the RLB9012-221KL have a higher maximum operating temperature?

A: The RLB9012-221KL specifies an operating range of -55°C to 125°C, compared to -55°C to 105°C for the 6000-221K-RC. This extended upper temperature limit reflects the current design specifications for the RLB9012 series and provides additional thermal headroom for applications operating in elevated temperature environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the 6000-221K-RC and RLB9012-221KL are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be specified for new designs?

A: The RLB9012-221KL should be specified for all new designs. The 6000-221K-RC carries a "Not For New Designs" designation and is intended only for legacy system support and maintenance applications.
