2000-2R7-V-RC Equivalent & Substitute Parts

Part Overview

The Bourns 2000-2R7-V-RC is a 2.7 µH unshielded toroidal inductor rated for 14.7 A continuous current with 3mOhm maximum DC resistance. This through-hole component is designed for radial, vertical mounting in applications requiring high current handling with minimal DC losses. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2000-2R7-V-RC is determined by the following critical parameters:

• Inductance Value: Must be 2.7 µH with ±20% tolerance
• Current Rating: Minimum 14.7 A continuous current capability
• DC Resistance: Maximum 3mOhm to maintain equivalent power loss characteristics
• Mounting Configuration: Through-hole, radial vertical orientation
• Shielding: Unshielded construction
• Compliance: ROHS3 compliant

The API Delevan DC630R-272M meets the inductance, tolerance, mounting, shielding, and compliance requirements. However, the current rating (12.8 A) falls below the original specification, and DC resistance (5mOhm) exceeds the maximum allowed value.

Parameter Comparison

Engineering Selection Recommendations

The DC630R-272M shares the same inductance value, tolerance, and unshielded configuration as the 2000-2R7-V-RC. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent applications.

Critical deviations exist in current rating and DC resistance. The substitute part is rated for 12.8 A versus the original 14.7 A specification, representing an 87% current capability. The DC resistance increases from 3mOhm to 5mOhm maximum, resulting in higher power dissipation under load. These differences must be evaluated against specific application requirements before substitution.

The DC630R-272M is currently active in production, providing supply continuity for the obsolete 2000-2R7-V-RC.

Frequently Asked Questions (FAQ)

Q: Can the DC630R-272M directly replace the 2000-2R7-V-RC in all applications?

A: Direct substitution requires verification that the application can tolerate 12.8 A maximum current (versus 14.7 A) and increased DC resistance of 5mOhm (versus 3mOhm). Applications operating near the original current rating or with strict power loss budgets require circuit analysis before substitution.

Q: What is the impact of the higher DC resistance in the substitute part?

A: At rated current, power dissipation increases proportionally with resistance. The 2mOhm increase results in higher heat generation. Thermal management and component temperature rise must be reassessed for the application.

Q: Are the physical dimensions compatible between these parts?

A: The 2000-2R7-V-RC measures 0.680" diameter by 0.410" width (toroidal). The DC630R-272M measures 0.630" diameter by 0.830" height (drum core cylinder). Physical layout compatibility must be verified for PCB or assembly fitment.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.4000).

Q: What is the inductance test frequency difference between these parts?

A: The original part is tested at 1 kHz, while the substitute is tested at 10 kHz. Inductance values may vary slightly across frequency ranges depending on core material and construction.
