Bourns 2309-V 47µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2309-V is a 47 µH unshielded toroidal inductor rated for 10.7 A continuous current with a maximum DC resistance of 16 mOhm. This through-hole component features an iron powder core and is designed for radial, vertical mounting in electronic circuits requiring stable inductance at 1 kHz test frequency across an operating temperature range of -55°C to 105°C.

The 2309-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this inductor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2309-V is determined by strict equivalence across the following critical parameters:

• Inductance value: 47 µH
• Current rating: 10.7 A minimum
• DC resistance: 16 mOhm maximum
• Tolerance: ±15%
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package / Case: Radial, Vertical (Open)
• Operating temperature range: -55°C ~ 105°C
• Physical dimensions: 1.280" Dia x 0.650" W (32.51mm x 16.51mm)

The substitute part 2309-V-RC meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status and packaging configuration, with the substitute part carrying active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The 2309-V-RC is the direct equivalent substitute for the obsolete 2309-V. Both parts are manufactured by Bourns Inc. within the 2300 series and maintain identical electrical specifications and physical dimensions.

The 2309-V-RC offers the following advantages for new designs and ongoing production:

• Active product status ensures continued availability and supply chain support
• ROHS3 compliance satisfies modern regulatory requirements, whereas the 2309-V is RoHS non-compliant
• Bulk packaging configuration supports higher-volume procurement
• Identical electrical performance across all critical parameters

For applications currently using the 2309-V, direct substitution with the 2309-V-RC requires no circuit modifications or re-qualification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 2309-V-RC be used as a direct replacement for the 2309-V in existing designs?

A: Yes. The 2309-V-RC is electrically and mechanically identical to the 2309-V. All inductance, current rating, DC resistance, tolerance, core material, shielding, mounting type, package configuration, and operating temperature specifications are equivalent. No circuit modifications are required.

Q: What is the primary difference between the 2309-V and 2309-V-RC?

A: The 2309-V is obsolete with RoHS non-compliant status, while the 2309-V-RC is an active product with ROHS3 compliance. The 2309-V-RC is supplied in bulk packaging, whereas the 2309-V packaging configuration differs. Electrical and mechanical specifications are identical.

Q: Are there any compliance considerations when switching from 2309-V to 2309-V-RC?

A: The 2309-V-RC carries ROHS3 compliance certification, making it suitable for applications subject to RoHS directives. The 2309-V is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: What are the critical parameters that define substitution eligibility for this inductor?

A: Substitution is determined by equivalence in inductance (47 µH), current rating (10.7 A), DC resistance (16 mOhm maximum), tolerance (±15%), core material (iron powder), shielding (unshielded), mounting type (through hole), package configuration (radial, vertical open), operating temperature range (-55°C to 105°C), and physical dimensions (1.280" Dia x 0.650" W).

Q: Is the 2309-V-RC available in the same packaging as the 2309-V?

A: The 2309-V-RC is supplied in bulk packaging. Both parts share identical through-hole radial vertical mounting configuration and physical dimensions, ensuring mechanical compatibility in PCB layouts.
