Bourns 6000-2R2M Equivalent & Substitute Parts

Part Overview

The Bourns 6000-2R2M is a 2.2 µH unshielded drum core wirewound inductor rated for 6.5 A with a maximum DC resistance of 21 mOhm. This through-hole radial component operates across -55°C to 105°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts are necessary for ongoing production and maintenance applications requiring identical or compatible electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-2R2M is determined by the following critical parameters: inductance value (2.2 µH), current rating (minimum 6.5 A), DC resistance (21 mOhm maximum), core material (ferrite), shielding configuration (unshielded), and mounting type (through-hole radial). Parts meeting these specifications are classified as direct or similar substitutes based on exact parameter alignment and product status.

The 6000-2R2M-RC qualifies as a direct substitute, maintaining identical electrical specifications and physical form factor while offering improved RoHS3 compliance. The 4554R-2R2M from API Delevan meets all core electrical requirements but operates within a narrower temperature range (-40°C to 85°C) and exhibits minor dimensional variations. The AIUR-03-2R2M from Abracon LLC maintains inductance, DCR, and core specifications but features a reduced current rating of 3.2 A with a saturation current of 6.5 A, making it suitable only for applications not requiring sustained 6.5 A operation.

Engineering Selection Recommendations

For applications requiring full parameter compatibility with the original 6000-2R2M, the 6000-2R2M-RC is the primary substitute. This part maintains identical electrical specifications and temperature range while offering RoHS3 compliance, making it suitable for both legacy system maintenance and new designs where Bourns components are specified.

The 4554R-2R2M from API Delevan serves as an alternative for applications operating within the -40°C to 85°C temperature window. This part is actively manufactured and RoHS3 compliant, providing long-term availability. Minor dimensional differences (0.340" diameter versus 0.354", 0.433" height versus 0.480") must be verified for PCB layout compatibility.

The AIUR-03-2R2M from Abracon LLC is suitable only for applications where the sustained current requirement does not exceed 3.2 A, despite its 6.5 A saturation rating. This part offers the tightest tolerance (±10%) and active production status but operates within a narrower temperature range (-25°C to 85°C). Selection of this part requires confirmation that circuit operation does not demand continuous 6.5 A current delivery.

Frequently Asked Questions (FAQ)

Q: Can the 6000-2R2M-RC be used as a direct replacement in existing designs?

A: Yes. The 6000-2R2M-RC maintains identical inductance (2.2 µH), current rating (6.5 A), DC resistance (21 mOhm), and operating temperature range (-55°C to 105°C). Physical dimensions and mounting type are identical. The primary difference is improved RoHS3 compliance.

Q: What is the key limitation of the AIUR-03-2R2M substitute?

A: The AIUR-03-2R2M has a continuous current rating of 3.2 A, compared to 6.5 A for the main part. Although its saturation current reaches 6.5 A, sustained operation above 3.2 A will cause excessive heating and potential inductor failure. Use this part only in applications with peak or intermittent current demands below 3.2 A.

Q: Are there dimensional concerns when substituting the 4554R-2R2M?

A: Yes. The 4554R-2R2M has a slightly smaller diameter (0.340" versus 0.354") and height (0.433" versus 0.480"). PCB footprint and component clearance must be verified before substitution to ensure mechanical fit within the assembly.

Q: Which substitute offers the best long-term availability?

A: The 4554R-2R2M and AIUR-03-2R2M are both actively manufactured. The 6000-2R2M-RC is classified as "Not For New Designs," indicating limited future availability. For new designs, the 4554R-2R2M or AIUR-03-2R2M are preferred, subject to electrical requirement verification.

Q: Do all substitutes maintain the same Q factor and self-resonant frequency?

A: Yes. All listed substitutes maintain Q = 20 @ 7.96 MHz and self-resonant frequency of 100 MHz, ensuring equivalent high-frequency performance characteristics.

Q: What compliance differences exist between the main part and substitutes?

A: The original 6000-2R2M is RoHS non-compliant. All three substitutes (6000-2R2M-RC, 4554R-2R2M, and AIUR-03-2R2M) are RoHS3 compliant. All parts are REACH unaffected and classified as EAR99 for export control purposes.
