Bourns 6000-1R0M Equivalent & Substitute Parts

Part Overview

The Bourns 6000-1R0M is a 1 µH unshielded drum core wirewound inductor rated for 10 A with a maximum DC resistance of 13 mOhm. This through-hole radial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 6000-1R0M is determined by the following critical parameters:

Inductance Value: Must be 1 µH
Current Rating: Must support minimum 10 A
DC Resistance: Must not exceed 13 mOhm
Mounting Type: Must be through-hole
Package Configuration: Must be radial, vertical cylinder
Shielding: Must be unshielded
Tolerance: Must be ±20%

The two identified substitutes meet these core electrical and mechanical requirements with variations in operating temperature range, physical dimensions, and product status.

Engineering Selection Recommendations

API Delevan 4554R-1R0M is the primary substitute for the Bourns 6000-1R0M. Both parts maintain identical electrical specifications: 1 µH inductance, 10 A current rating, and 13 mOhm maximum DC resistance. The API Delevan part is active in production and ROHS3 compliant. Physical dimensions differ slightly (0.340" diameter vs. 0.354"), but both maintain the radial vertical cylinder package configuration. The operating temperature range is narrower (-40°C to 85°C vs. -55°C to 105°C), which may be a limiting factor in extreme temperature applications.

Abracon AIUR-03-1R0M is a secondary substitute with the same inductance and DC resistance specifications. However, the current rating is reduced to 4.6 A, making this part suitable only for applications where the circuit operates below this threshold. The operating temperature range is further restricted (-25°C to 85°C). This part is ROHS3 compliant and active in production. Physical dimensions match the original Bourns part (0.354" diameter).

Selection between the two substitutes depends on application current requirements and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4554R-1R0M directly replace the Bourns 6000-1R0M?

A: Yes, for applications operating within -40°C to 85°C and requiring up to 10 A. The electrical specifications are identical. Physical dimensions are similar but not exact; verify PCB layout compatibility before implementation.

Q: Why is the Abracon AIUR-03-1R0M listed as a substitute if the current rating is only 4.6 A?

A: The Abracon part meets the core electrical parameters (inductance, DC resistance, tolerance, and frequency characteristics) and physical package requirements. It is suitable only for circuits where the actual operating current does not exceed 4.6 A, even if the original design specified 10 A capacity.

Q: What is the impact of the narrower operating temperature range in the API Delevan part?

A: The API Delevan 4554R-1R0M operates from -40°C to 85°C, compared to the original -55°C to 105°C range. Applications requiring operation below -40°C or above 85°C cannot use this substitute without thermal analysis and validation.

Q: Are there physical dimension differences that affect PCB layout?

A: Yes. The API Delevan part is 0.340" diameter (8.64 mm) with 0.433" height (11.00 mm), while the Bourns original and Abracon substitute are 0.354" diameter (9.00 mm). Height also varies: Bourns 0.480" (12.20 mm), Abracon 0.472" (12.00 mm). Verify footprint compatibility on your PCB.

Q: Are both substitutes RoHS compliant?

A: Yes. Both the API Delevan 4554R-1R0M and Abracon AIUR-03-1R0M are ROHS3 compliant, while the original Bourns 6000-1R0M is RoHS non-compliant.

Q: What is the difference between the Bourns and Abracon core types?

A: Both are drum core wirewound inductors with ferrite material. The API Delevan part does not specify core type in the provided data but maintains equivalent electrical performance.
