Substitute Part Grouping Explanation

Substitution eligibility for the 6000-560K-RC is determined by the following critical parameters:

Inductance value: 56 µH (exact match required)
Inductance tolerance: ±10% (exact match required)
DC resistance: 180 mOhm maximum (exact match required)
Core material: Ferrite, unshielded (exact match required)
Mounting type: Through hole (exact match required)
Package configuration: Radial, vertical cylinder (exact match required)
Physical dimensions: 0.354" diameter, 0.480" maximum seated height (exact match required)
Current rating: Minimum 1.48 A (equal or greater acceptable)
Operating temperature range: Minimum -55°C to 105°C (equal or wider range acceptable)
Compliance: ROHS3 compliant (required for new stock)

Two substitute parts meet these criteria with varying degrees of parameter alignment.

Engineering Selection Recommendations

RLB9012-560KL (Bourns Inc.) - Direct Substitute

The RLB9012-560KL is the primary equivalent for the 6000-560K-RC. Both parts are manufactured by Bourns Inc. and share identical electrical specifications: 56 µH inductance, ±10% tolerance, 1.48 A current rating, and 180 mOhm maximum DC resistance. Physical dimensions are identical. The RLB9012-560KL features an extended operating temperature range (-55°C to 125°C) compared to the main part, providing broader thermal compatibility. The part carries Active product status with ROHS3 compliance and is available in tray packaging. This substitute is suitable for direct replacement in applications requiring the full 1.48 A current rating and the original temperature specification.

AIUR-03-560K (Abracon LLC) - Similar Substitute with Limitations

The AIUR-03-560K from Abracon LLC matches the inductance, tolerance, DC resistance, core material, and physical dimensions of the main part. However, this substitute has a reduced current rating of 900 mA compared to the required 1.48 A, making it unsuitable for applications operating at or near the original current specification. The operating temperature range (-25°C to 85°C) is narrower than the main part, restricting use in applications requiring the full -55°C to 105°C range. This part is suitable only for applications where current demand does not exceed 900 mA and operating temperatures remain within -25°C to 85°C. The AIUR-03-560K carries Active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-560KL replace the 6000-560K-RC in all applications?

A: Yes. The RLB9012-560KL matches all critical electrical and mechanical parameters of the 6000-560K-RC. The extended temperature range of the RLB9012-560KL (-55°C to 125°C) provides additional thermal margin beyond the original specification (-55°C to 105°C). Both parts are ROHS3 compliant and feature identical inductance, current rating, and DC resistance specifications.

Q: When is the AIUR-03-560K appropriate as a substitute?

A: The AIUR-03-560K is appropriate only in applications where the circuit current requirement does not exceed 900 mA and the operating environment remains within -25°C to 85°C. Applications requiring the full 1.48 A rating or extended temperature operation must use the RLB9012-560KL.

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

A: The 6000-560K-RC and AIUR-03-560K are supplied in bulk packaging, while the RLB9012-560KL is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects supplier inventory and handling methods.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 6000-560K-RC, RLB9012-560KL, and AIUR-03-560K are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing.

Q: Why is the 6000-560K-RC marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Bourns Inc. has discontinued active development and promotion of this part number. The RLB9012-560KL, which carries Active status, is the recommended path forward for new designs and ongoing production requiring this inductor specification.
