Bourns 6000-221K Equivalent & Substitute Parts

Part Overview

The Bourns 6000-221K is a 220 µH unshielded drum core wirewound inductor rated for 1 A with a maximum DC resistance of 650 mOhm. This through-hole component features a radial, vertical cylinder package and operates across a temperature range of -55°C to 105°C. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

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

• Inductance value: 220 µH with ±10% tolerance
• Current rating: 1 A minimum
• DC resistance: 650 mOhm maximum
• Core type: Ferrite, unshielded drum core
• Mounting configuration: Through-hole, radial vertical cylinder
• Physical footprint: 0.354" diameter, 0.480" maximum height
• Operating temperature range: -55°C to 105°C

The substitute part 6000-221K-RC meets all these criteria and is manufactured by the same supplier (Bourns Inc.) within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The 6000-221K-RC serves as the direct substitute for the obsolete 6000-221K. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is regulatory compliance: the 6000-221K-RC achieves ROHS3 compliance, whereas the original part does not. For applications requiring RoHS compliance or for new procurement, the 6000-221K-RC is the appropriate selection. Both parts maintain identical electrical performance, physical footprint, and thermal operating range, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 6000-221K-RC be used as a direct replacement for the 6000-221K?

A: Yes. The 6000-221K-RC is electrically and mechanically equivalent to the 6000-221K across all specified parameters, including inductance, current rating, DC resistance, core material, physical dimensions, and operating temperature range.

Q: What is the difference between these two parts?

A: The primary difference is product status and RoHS compliance. The 6000-221K is obsolete and RoHS non-compliant, while the 6000-221K-RC is marked "Not For New Designs" and achieves ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between the two parts?

A: The 6000-221K is supplied in standard packaging, while the 6000-221K-RC is supplied in bulk packaging. Both maintain the same radial, vertical cylinder physical form factor and are compatible with identical PCB footprints.

Q: What parameters must match for substitution?

A: Substitution requires equivalence in inductance (220 µH ±10%), current rating (1 A), DC resistance (650 mOhm maximum), core material (ferrite, unshielded), mounting type (through-hole), package configuration (radial vertical cylinder), and physical dimensions (0.354" diameter, 0.480" height).

Q: Is the 6000-221K-RC suitable for new designs?

A: The 6000-221K-RC carries a "Not For New Designs" status. For new applications, consult the Bourns product line for current-generation alternatives that meet modern design requirements and compliance standards.
