Bourns 2308-V 39µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2308-V is a 39 µH unshielded toroidal inductor rated for 11.2 A continuous current with a maximum DC resistance of 14 mOhm. This through-hole component features an iron powder core and is designed for radial, vertical mounting in applications requiring stable inductance at 1 kHz test frequency across an operating temperature range of -55°C to 105°C.

The 2308-V carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications currently using this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2308-V is determined by strict equivalence across electrical and mechanical parameters. The substitute part must maintain:

• Identical inductance value: 39 µH
• Matching inductance tolerance: ±15%
• Equal or greater current rating: 11.2 A minimum
• DC resistance not exceeding: 14 mOhm maximum
• Identical core material: Iron Powder
• Matching shielding configuration: Unshielded
• Compatible mounting: Through Hole
• Identical package geometry: Radial, Vertical (Open)
• Matching physical dimensions: 1.280" Dia × 0.650" W
• Operating temperature range: -55°C to 105°C minimum

The 2308-V-RC meets all these criteria as a direct electrical and mechanical equivalent within the Bourns 2300 series.

Parameter Comparison

Engineering Selection Recommendations

The 2308-V-RC is the direct substitute for the obsolete 2308-V. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product lifecycle status and regulatory compliance.

The 2308-V carries obsolete status with RoHS non-compliance. The 2308-V-RC maintains active product status and achieves ROHS3 compliance, making it the appropriate selection for new designs and ongoing production requiring regulatory alignment. Both components are unaffected by REACH regulations and classified under ECCN EAR99.

For applications currently using the 2308-V, direct substitution with the 2308-V-RC requires no circuit redesign or board layout modification due to identical electrical performance and physical footprint.

Frequently Asked Questions (FAQ)

Q: Can the 2308-V-RC replace the 2308-V in existing designs?

A: Yes. The 2308-V-RC is a direct substitute with identical inductance (39 µH), current rating (11.2 A), DC resistance (14 mOhm maximum), core material (iron powder), and physical dimensions (1.280" Dia × 0.650" W). No circuit or layout changes are required.

Q: What is the key difference between these two parts?

A: The 2308-V is obsolete and RoHS non-compliant. The 2308-V-RC is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between 2308-V and 2308-V-RC?

A: The 2308-V is supplied in standard packaging. The 2308-V-RC is supplied in bulk packaging. Both use identical through-hole radial, vertical (open) package geometry with no impact on circuit board assembly or performance.

Q: What inductance tolerance should be expected?

A: Both the 2308-V and 2308-V-RC carry ±15% inductance tolerance at 1 kHz test frequency. Circuit designs must account for this tolerance range in inductance-critical applications.

Q: Are these components suitable for high-temperature applications?

A: Both components operate across -55°C to 105°C. Applications requiring operation outside this range require alternative component selection.

Q: Does the unshielded design affect EMI performance?

A: Both components are unshielded toroidal inductors. Circuit layout and shielding strategy must be evaluated based on application EMI requirements.
