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

Part Overview

The Bourns 2000-2R7-H-RC is a 2.7 µH unshielded toroidal inductor rated for 14.7 A continuous current with a maximum DC resistance of 3mOhm. This through-hole component operates across -55°C to 105°C and is designed for radial, horizontal mounting orientation. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

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

• Inductance value: 2.7 µH with ±20% tolerance
• Current rating: minimum 14.7 A continuous
• DC resistance: maximum 5mOhm (allowing slight increase from 3mOhm specification)
• Shielding configuration: unshielded
• Mounting type: through-hole
• Operating temperature range: minimum -55°C to 105°C coverage
• RoHS3 compliance and REACH unaffected status

The API Delevan DC630R-272M meets these substitution criteria with equivalent inductance and tolerance, though with a lower current rating of 12.8 A and slightly higher DCR of 5mOhm. The substitute maintains unshielded construction, through-hole mounting, and required compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DC630R-272M from API Delevan is an active product with current manufacturing support and full compliance certifications (ROHS3, REACH unaffected). As an active component, it provides supply chain continuity for the obsolete 2000-2R7-H-RC.

The substitute maintains electrical equivalence in inductance value and tolerance. The current rating reduction from 14.7 A to 12.8 A and DCR increase from 3mOhm to 5mOhm represent measurable parameter shifts that must be evaluated against specific circuit requirements. The extended operating temperature range to 125°C provides additional thermal margin.

Selection of the DC630R-272M is appropriate for applications where the 12.8 A current rating and 5mOhm DCR specifications satisfy circuit design constraints.

Frequently Asked Questions (FAQ)

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

A: Both components share identical inductance (2.7 µH) and tolerance (±20%), unshielded construction, and through-hole mounting. However, the substitute has a lower current rating (12.8 A vs. 14.7 A) and higher DCR (5mOhm vs. 3mOhm). Substitution is valid only when circuit current requirements do not exceed 12.8 A and the higher DCR does not compromise performance.

Q: What are the physical mounting differences between these inductors?

A: The 2000-2R7-H-RC uses radial, horizontal (open) orientation with 0.680" diameter and 0.410" seated height. The DC630R-272M uses radial, vertical cylinder orientation with 0.630" diameter and 0.830" seated height. PCB layout and mechanical clearance must be verified before substitution.

Q: Are both components RoHS compliant?

A: Yes, both the 2000-2R7-H-RC and DC630R-272M are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Why is the original part obsolete?

A: The 2000-2R7-H-RC is listed as obsolete by Bourns. The DC630R-272M is an active product from API Delevan with ongoing manufacturing and supply availability.
