Bourns 2301-H 10µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2301-H is a 10 µH unshielded toroidal inductor rated for 20 A continuous current with a maximum DC resistance of 5 mOhm. This through-hole component features an iron powder core and radial, horizontal mounting configuration. The 2301-H is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The 2301-H-RC serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved compliance status.

Substitute Part Grouping Explanation

The 2301-H-RC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters: identical inductance value of 10 µH at ±15% tolerance, equivalent 20 A current rating, matching 5 mOhm maximum DC resistance, identical core material (iron powder), and matching physical dimensions (1.280" diameter, 0.650" maximum seated height). Both components utilize through-hole mounting with radial, horizontal (open) package configuration and operate across the same temperature range (-55°C to 105°C). The substitution is valid for applications requiring these exact specifications without modification to PCB layout or mechanical assembly.

Engineering Selection Recommendations

The 2301-H-RC is the appropriate selection for new designs and production applications. As an active product with ROHS3 compliance, it provides supply chain continuity and regulatory alignment. The obsolete 2301-H should be replaced in existing designs where component refresh cycles permit. Both parts maintain identical electrical performance and physical footprint, enabling direct PCB substitution without design modification. The 2301-H-RC's active status ensures long-term availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 2301-H-RC replace the 2301-H in existing assemblies? A: Yes. The 2301-H-RC is a direct substitute with identical inductance (10 µH), current rating (20 A), DC resistance (5 mOhm), core material (iron powder), and physical dimensions. No PCB or mechanical modifications are required.

Q: What is the primary difference between these parts? A: The 2301-H-RC is an active product with ROHS3 compliance, while the 2301-H is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences? A: The 2301-H-RC is supplied in bulk packaging, while the 2301-H packaging specification is not defined. This does not affect electrical or mechanical compatibility.

Q: Do both parts operate across the same temperature range? A: Yes. Both the 2301-H and 2301-H-RC operate from -55°C to 105°C.

Q: Is the inductance tolerance the same for both parts? A: Yes. Both parts maintain ±15% inductance tolerance at 1 kHz test frequency.
