Bourns 6000-560K Equivalent & Substitute Parts

Part Overview

The Bourns 6000-560K is a 56 µH unshielded drum core wirewound inductor rated for 1.48 A with a maximum DC resistance of 180 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 classified as obsolete, making identification of suitable alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-560K is determined by the following critical parameters: inductance value (56 µH), current rating capability, DC resistance specification (180 mOhm Max), core material (ferrite), mounting type (through hole), and package form factor (radial, vertical cylinder).

The substitute parts are categorized as follows:

Direct Equivalent (AIUR-03-560K): Matches the primary electrical specifications including inductance (56 µH), DC resistance (180 mOhm Max), core material (ferrite), and package form factor. Substitution is valid within the constraints of differing current ratings and operating temperature ranges.

Partial Equivalent (CW160808-6N8J): Differs significantly in inductance value (6.8 nH vs. 56 µH), current rating (700 mA vs. 1.48 A), mounting type (surface mount vs. through hole), and package form factor (0603 metric vs. radial vertical cylinder). This part does not qualify as a functional substitute for the 6000-560K.

Engineering Selection Recommendations

AIUR-03-560K (Abracon LLC): This part qualifies as the primary substitute for the 6000-560K. Both components share identical inductance (56 µH), DC resistance specification (180 mOhm Max), tolerance (±10%), core material (ferrite), and package form factor (radial, vertical cylinder). The AIUR-03-560K is currently in active production status with ROHS3 compliance certification. The primary design consideration is the reduced current rating (900 mA vs. 1.48 A) and narrower operating temperature range (-25°C to 85°C vs. -55°C to 105°C). Selection of this substitute requires verification that circuit current demands do not exceed 900 mA and that the operating environment remains within the specified temperature limits.

CW160808-6N8J (Bourns Inc.): This part is not suitable as a substitute for the 6000-560K. The inductance value (6.8 nH) is fundamentally incompatible with the required 56 µH specification. Additionally, the surface mount package and 0603 form factor are incompatible with through-hole mounting requirements. This part operates in a different frequency domain (250 MHz test frequency vs. 2.52 MHz) and serves applications requiring significantly lower inductance values.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-03-560K replace the 6000-560K in all applications?

A: The AIUR-03-560K is electrically compatible for applications where circuit current does not exceed 900 mA and operating temperature remains within -25°C to 85°C. If the original design requires the full 1.48 A current rating or operates outside this temperature range, the AIUR-03-560K is not suitable.

Q: Why is the CW160808-6N8J listed as a substitute if it cannot replace the 6000-560K?

A: The CW160808-6N8J is included in the substitute list but does not meet the functional requirements of the 6000-560K. It is provided for reference only and is not recommended for direct substitution.

Q: What are the key differences between the 6000-560K and AIUR-03-560K?

A: The primary differences are current rating (1.48 A vs. 900 mA), operating temperature range (-55°C to 105°C vs. -25°C to 85°C), and manufacturer (Bourns vs. Abracon). All other critical parameters including inductance, DC resistance, tolerance, core material, and package form factor are identical.

Q: Are there any compliance considerations when switching to the AIUR-03-560K?

A: The AIUR-03-560K carries ROHS3 compliance certification, whereas the 6000-560K is non-compliant. This may be advantageous for designs requiring regulatory compliance with RoHS directives.

Q: What mounting considerations apply to the AIUR-03-560K?

A: The AIUR-03-560K maintains the same through-hole radial, vertical cylinder package as the 6000-560K, allowing direct PCB mounting compatibility without layout modifications.
