Bourns 5230 4µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5230 is a 4µH unshielded drum core wirewound inductor rated for 8A continuous current with a maximum DC resistance of 12mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5230 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Bourns 5230 is determined by strict equivalence across the following critical parameters:

• Inductance value: 4 µH
• Inductance tolerance: ±20%
• Current rating: 8 A minimum
• DC resistance: 12 mOhm maximum
• Core type: Ferrite drum core
• Shielding configuration: Unshielded
• Mounting: Through hole axial
• Physical dimensions: 0.380" Dia × 0.875" L
• Operating temperature range: -55°C to 105°C

The substitute part must match all electrical specifications and physical form factor to ensure direct compatibility without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5230-RC is a direct electrical and mechanical equivalent to the obsolete Bourns 5230. All critical inductance, current, resistance, and thermal parameters are identical. The primary distinction is product status and regulatory compliance.

The 5230-RC is in active production, ensuring long-term availability and supply chain stability. The component carries ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original 5230 does not.

For new designs or ongoing production requiring this inductance value and current rating, the 5230-RC is the appropriate selection. For legacy system repairs where original component specifications must be maintained, the 5230-RC provides full functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 5230-RC be used as a direct replacement for the 5230 in existing designs?

A: Yes. The 5230-RC matches all electrical specifications (inductance, current rating, DC resistance, temperature range) and physical dimensions (axial through-hole package) of the 5230. No circuit modification or board layout change is required.

Q: What is the difference between the 5230 and 5230-RC?

A: Both components are electrically and mechanically identical. The 5230-RC is the current production variant with ROHS3 compliance. The original 5230 is obsolete and non-compliant with current environmental standards.

Q: Are there packaging differences between these parts?

A: The 5230 is supplied in standard packaging, while the 5230-RC is supplied in bulk packaging. Both use identical axial through-hole form factors and are compatible with the same PCB footprints.

Q: What parameters must match for substitution?

A: Inductance (4 µH), tolerance (±20%), current rating (8 A), DC resistance (12 mOhm max), core material (ferrite), shielding (unshielded), mounting type (through hole), package style (axial), and physical dimensions (0.380" Dia × 0.875" L) must all match exactly.

Q: Is the 5230-RC suitable for high-frequency applications?

A: Both the 5230 and 5230-RC have a self-resonant frequency of 165 MHz. Component selection for high-frequency applications must account for this specification in addition to the DC inductance value.
