Bourns 2301-V 10µH 20A Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2301-V 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 vertical mounting configuration. The 2301-V is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The 2301-V-RC serves as the direct active production substitute, maintaining identical electrical and mechanical specifications while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2301-V is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 10 µH (fixed specification)
• Current rating: 20 A minimum
• DC resistance: 5 mOhm maximum
• Tolerance: ±15% or tighter
• Operating temperature range: -55°C to 105°C minimum

Mechanical Equivalence Requirements:

• Core type: Iron powder
• Shielding: Unshielded
• Mounting: Through hole
• Package: Radial, vertical (open) configuration
• Physical dimensions: 1.280" Dia × 0.650" W

The 2301-V-RC is classified as a direct substitute because it maintains identical specifications across all electrical and mechanical parameters while offering active product status and improved regulatory compliance.

Engineering Selection Recommendations

Primary Selection: Bourns 2301-V-RC

The 2301-V-RC is the recommended substitute for the obsolete 2301-V. This part maintains complete electrical and mechanical equivalence while offering two significant advantages:

1. Active Product Status: The 2301-V-RC is in active production, ensuring long-term availability and supply chain continuity.

2. Regulatory Compliance: The 2301-V-RC achieves ROHS3 compliance, whereas the original 2301-V is non-compliant. This compliance improvement is relevant for applications subject to RoHS directives and environmental regulations.

Both parts share identical inductance, current rating, DC resistance, tolerance, core material, shielding, mounting type, package configuration, and operating temperature range. PCB layout and assembly procedures require no modification when transitioning from 2301-V to 2301-V-RC.

Frequently Asked Questions (FAQ)

Q: Can the 2301-V-RC be used as a direct replacement for the 2301-V?

A: Yes. The 2301-V-RC is electrically and mechanically identical to the 2301-V across all specified parameters. No circuit modifications or PCB redesign is required.

Q: What is the difference between the 2301-V and 2301-V-RC?

A: The primary differences are product status and regulatory compliance. The 2301-V is obsolete and RoHS non-compliant. The 2301-V-RC is in active production and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 2301-V is supplied in standard packaging, while the 2301-V-RC is supplied in bulk packaging. Both maintain the same radial, vertical (open) configuration and physical dimensions of 1.280" Dia × 0.650" W.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: inductance (10 µH), current rating (20 A), DC resistance (5 mOhm maximum), tolerance (±15%), core material (iron powder), shielding (unshielded), mounting type (through hole), and package configuration (radial, vertical open).

Q: Is the 2301-V-RC suitable for new designs?

A: Yes. The 2301-V-RC is the active production part and is appropriate for both new designs and legacy system support.
