Bourns 6000-150K Equivalent & Substitute Parts

Part Overview

The Bourns 6000-150K is a 15 µH unshielded drum core wirewound inductor rated for 2.9 A with a maximum DC resistance of 56 mOhm. This through-hole radial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 6000-150K carries an obsolete product status, making it necessary to identify equivalent substitute parts for ongoing production and maintenance applications. The primary substitute maintains identical electrical and mechanical specifications while offering improved compliance status and current inventory availability.

Substitute Part Grouping Explanation

Substitution of the Bourns 6000-150K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 6000-150K-RC maintains identical specifications in the following key areas:

Inductance value and tolerance (15 µH ±10%)
Current rating and DC resistance (2.9 A, 56 mOhm Max)
Core material and shielding configuration (Ferrite, Unshielded)
Frequency characteristics (Q @ 2.52 MHz, Self Resonant Frequency)
Operating temperature range (-55°C to 105°C)
Physical dimensions and mounting configuration (Through Hole, Radial Vertical Cylinder)
Package footprint (0.354" Dia × 0.480" Height Max)

The 6000-150K-RC differs only in packaging format (Bulk vs. standard) and compliance status, with no impact on electrical or mechanical performance in equivalent circuit applications.

Engineering Selection Recommendations

The 6000-150K-RC serves as the direct substitute for the obsolete 6000-150K. Selection between these parts is determined by compliance and product lifecycle requirements:

For RoHS3-compliant applications: The 6000-150K-RC is required, as it meets RoHS3 compliance standards while the original 6000-150K does not.

For legacy system maintenance: The 6000-150K remains available in limited inventory (798 Pcs) for direct replacement in existing designs where RoHS compliance is not mandated.

For new design implementation: The 6000-150K-RC is the appropriate selection, offering superior inventory availability (1,588 Pcs) and compliance certification, despite its "Not For New Designs" status designation.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 6000-150K-RC be used as a direct replacement for the 6000-150K?

A: Yes. The 6000-150K-RC is electrically and mechanically equivalent to the 6000-150K across all specified parameters, including inductance, current rating, DC resistance, frequency response, and physical dimensions. Substitution requires no circuit modifications.

Q: What is the difference between the 6000-150K and 6000-150K-RC?

A: The primary differences are packaging format (Standard vs. Bulk) and compliance status (RoHS Non-Compliant vs. RoHS3 Compliant). Electrical and mechanical specifications are identical.

Q: Why is the 6000-150K marked as obsolete?

A: The 6000-150K has reached end-of-life status within Bourns' product portfolio. The 6000-150K-RC represents the current equivalent offering with improved compliance and availability.

Q: Are there any thermal or frequency limitations when substituting these parts?

A: No. Both parts operate identically across the -55°C to 105°C temperature range and maintain the same Q factor (50 @ 2.52 MHz) and self-resonant frequency (12 MHz).

Q: What is the impact of bulk packaging on component performance?

A: Packaging format does not affect electrical or mechanical performance. Bulk packaging is a supply chain consideration only and does not alter component specifications or circuit behavior.

Q: Can these inductors be used in high-frequency applications above 12 MHz?

A: The self-resonant frequency of 12 MHz defines the upper frequency limit for these components. Operation above this frequency is not recommended due to resonance effects.
