Bourns 6000-471K Equivalent & Substitute Parts

Part Overview

The Bourns 6000-471K is a 470 µH unshielded drum core wirewound inductor rated for 680 mA with a maximum DC resistance of 1.1 Ohm. This through-hole radial component features a ferrite core and operates across the temperature range of -55°C to 105°C. The part is classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the 6000-471K are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters: Inductance value (470 µH), current rating (680 mA minimum), DC resistance (1.1 Ohm maximum), and core material (ferrite).

Mechanical Parameters: Mounting type (through hole), package configuration (radial, vertical cylinder), and physical dimensions compatible with the original footprint.

Compliance Parameters: RoHS status and REACH compliance status.

The 6000-471K-RC maintains identical electrical specifications and physical dimensions while offering improved RoHS3 compliance. The CW160808-68NJ, while manufactured by Bourns, operates at a significantly different inductance value (68 nH versus 470 µH) and uses surface mount packaging, making it unsuitable as a direct functional equivalent despite being listed in the original substitute field.

Engineering Selection Recommendations

For Direct Replacement (Recommended): The 6000-471K-RC is the appropriate substitute for the obsolete 6000-471K. Both parts maintain identical electrical specifications (470 µH inductance, 680 mA current rating, 1.1 Ohm maximum DC resistance) and physical dimensions. The 6000-471K-RC offers the advantage of ROHS3 compliance, addressing regulatory requirements for new production while maintaining full functional compatibility with existing circuit designs.

For Alternative Applications: The CW160808-68NJ is not suitable as a functional replacement for the 6000-471K due to fundamental differences in inductance value (68 nH versus 470 µH), mounting technology (surface mount versus through hole), and package form factor. This part operates in a different application space and would require circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 6000-471K-RC be used as a direct replacement for the 6000-471K?

A: Yes. The 6000-471K-RC is electrically and mechanically identical to the 6000-471K, with matching inductance (470 µH), current rating (680 mA), DC resistance (1.1 Ohm maximum), and physical dimensions. The primary difference is improved RoHS3 compliance status.

Q: Why is the CW160808-68NJ listed as a substitute if it cannot replace the 6000-471K?

A: The CW160808-68NJ differs fundamentally in inductance value (68 nH versus 470 µH), mounting type (surface mount versus through hole), and package configuration. This part is suitable only for applications requiring significantly lower inductance values and surface mount assembly.

Q: What are the key parameters that determine substitutability?

A: Inductance value, current rating, DC resistance, core material, mounting type, and package configuration are the primary parameters. The 6000-471K-RC matches all these criteria with the original part.

Q: Are there compliance differences between the 6000-471K and 6000-471K-RC?

A: Yes. The 6000-471K is RoHS non-compliant, while the 6000-471K-RC is ROHS3 compliant. Both maintain REACH unaffected status.

Q: What is the product status difference, and does it affect selection?

A: The 6000-471K is classified as obsolete, while the 6000-471K-RC is marked as not for new designs. For new production, the 6000-471K-RC is the appropriate choice. For legacy system maintenance, either part may be used depending on inventory and compliance requirements.
