Bourns 6000-1R5M Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 6000-1R5M is a 1.5 µH unshielded drum core wirewound inductor rated for 8.5 A continuous current with 16 mOhm maximum DC resistance. This through-hole radial component operates across -55°C to 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-1R5M is determined by the following critical parameters:

Primary Matching Criteria:

Inductance value: 1.5 µH (±20% tolerance)
DC resistance: 16 mOhm maximum
Current rating: minimum 8.5 A
Core material: Ferrite
Shielding: Unshielded
Mounting: Through hole radial configuration
Package: Vertical cylinder form factor

Compliance Considerations:

RoHS3 compliance status
REACH compliance status
Operating temperature range compatibility with application requirements

Parts are grouped as direct equivalents when all primary parameters match within specification. Parts with reduced current ratings or narrower temperature ranges are classified as similar substitutes with application-dependent suitability.

Engineering Selection Recommendations

6000-1R5M-RC (Bourns Inc.): Direct electrical and mechanical equivalent with identical specifications. Maintains full 8.5 A current rating and -55°C to 105°C operating range. Achieves RoHS3 compliance. Classified as "Not For New Designs" but suitable for legacy system maintenance and repair applications requiring exact parameter matching.

4554R-1R5M (API Delevan Inc.): Active product status with full electrical equivalence. Maintains 8.5 A current rating and 16 mOhm DC resistance. Operating temperature range reduced to -40°C to 85°C. Physical dimensions slightly smaller (0.340" diameter vs. 0.354"). RoHS3 compliant. Suitable for applications within the narrower temperature specification.

AIUR-03-1R5M (Abracon LLC): Active product with matching inductance, tolerance, and DC resistance. Current rating reduced to 3.3 A continuous (saturation current 8.5 A). Operating temperature range -25°C to 85°C. RoHS3 compliant with MSL 1 rating. Suitable only for applications with current requirements not exceeding 3.3 A continuous operation.

Frequently Asked Questions (FAQ)

Q: Can the 6000-1R5M-RC directly replace the obsolete 6000-1R5M?

A: Yes. The 6000-1R5M-RC is a direct equivalent with identical electrical specifications (1.5 µH, 8.5 A, 16 mOhm), matching operating temperature range (-55°C to 105°C), and identical package geometry. The primary difference is RoHS3 compliance status.

Q: Is the 4554R-1R5M suitable for all applications using the 6000-1R5M?

A: The 4554R-1R5M matches all electrical parameters and current rating. Substitution is valid only if the application operates within -40°C to 85°C. Applications requiring the full -55°C to 105°C range require the 6000-1R5M-RC or equivalent.

Q: Why is the AIUR-03-1R5M listed as a similar substitute despite lower current rating?

A: The AIUR-03-1R5M matches inductance, tolerance, DC resistance, and frequency characteristics. The 3.3 A continuous rating is a limiting factor. This part is suitable only for applications with current requirements below 3.3 A, despite the 8.5 A saturation current specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 6000-1R5M-RC, 4554R-1R5M, and AIUR-03-1R5M are all RoHS3 compliant. The original 6000-1R5M is non-compliant, making substitution necessary for RoHS-regulated applications.

Q: What are the physical dimension differences between substitute parts?

A: The 6000-1R5M and 6000-1R5M-RC share identical dimensions (0.354" diameter, 0.480" height). The 4554R-1R5M is slightly smaller (0.340" diameter, 0.433" height). The AIUR-03-1R5M matches the main part dimensions (0.354" diameter, 0.472" height). Verify PCB layout compatibility before substitution.

Q: Can these parts be used interchangeably in production?

A: Direct interchange is limited to 6000-1R5M and 6000-1R5M-RC. The 4554R-1R5M and AIUR-03-1R5M require application-specific validation due to temperature range and current rating differences respectively.
