Bourns 5800-3R9 Equivalent & Substitute Parts

Part Overview

The Bourns 5800-3R9 is a 3.9 µH unshielded drum core wirewound inductor rated for 3.1 A with a maximum DC resistance of 15 mOhm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5800-3R9 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 systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5800-3R9 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Inductance value: 3.9 µH
• Core material: Ferrite
• Mounting type: Through hole axial
• Operating temperature range: Minimum -55°C to 105°C
• Shielding configuration: Unshielded

Allowable Variation Parameters:

• Current rating: Must meet or exceed 3.1 A
• DC resistance: Must not exceed 15 mOhm
• Tolerance: ±10% or tighter acceptable
• Physical dimensions: Minor variations acceptable within through-hole axial form factor constraints

The 5800-3R9-RC is a direct equivalent manufactured by Bourns Inc., differing only in packaging format and product status. The 2474-08L from API Delevan Inc. is a similar substitute meeting the core electrical requirements with allowable parameter variations.

Engineering Selection Recommendations

5800-3R9-RC (Direct Equivalent - Recommended for Primary Substitution)

The 5800-3R9-RC is the preferred substitute. It maintains identical electrical specifications and physical dimensions as the obsolete 5800-3R9. The primary distinction is product status: the 5800-3R9-RC is active and carries ROHS3 compliance certification, whereas the original part is obsolete and non-compliant. Packaging differs (tray versus unspecified), but electrical performance and form factor are equivalent. This part is suitable for direct replacement in all applications where the 5800-3R9 was originally specified.

2474-08L (Similar Substitute - Conditional Use)

The 2474-08L from API Delevan Inc. meets the core inductance and ferrite core requirements. It exceeds the current rating specification (4.56 A versus 3.1 A required) and operates across an extended temperature range (-55°C to 125°C). However, the saturation current is lower (3.2 A versus 5.8 A), and DC resistance is slightly elevated (17 mOhm Max versus 15 mOhm Max). The inductor type differs (molded versus drum core wirewound), and physical dimensions vary slightly. This part is suitable for applications where the lower saturation current and higher DC resistance do not present design constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5800-3R9-RC be used as a direct replacement for the 5800-3R9?

A: Yes. The 5800-3R9-RC is electrically and mechanically identical to the 5800-3R9. Both components feature 3.9 µH inductance, 3.1 A current rating, 15 mOhm maximum DC resistance, and identical physical dimensions. The primary difference is product status and RoHS compliance. The 5800-3R9-RC is active and ROHS3 compliant, making it the recommended substitute for the obsolete 5800-3R9.

Q: What are the key differences between the 5800-3R9-RC and the 2474-08L?

A: Both parts share the same 3.9 µH inductance value and ferrite core material. The 5800-3R9-RC is a drum core wirewound inductor, while the 2474-08L is a molded inductor. The 2474-08L provides higher current rating (4.56 A) and extended temperature range (-55°C to 125°C), but exhibits lower saturation current (3.2 A) and slightly higher DC resistance (17 mOhm Max). Physical dimensions also differ slightly.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The 5800-3R9 and 5800-3R9-RC are supplied in different packaging formats (unspecified versus tray). The 2474-08L is supplied in bulk packaging. Verify that packaging format is compatible with your assembly and procurement processes before finalizing component selection.

Q: Which substitute should be selected for new designs?

A: The 5800-3R9-RC is the appropriate choice for new designs. It provides direct electrical and mechanical equivalence to the original specification while offering active product status and ROHS3 compliance. The 2474-08L may be considered only if design requirements specifically accommodate its parameter variations.

Q: Does the 2474-08L saturation current of 3.2 A present a compatibility issue?

A: The saturation current specification must be evaluated against your circuit design requirements. The 2474-08L saturation current (3.2 A) is lower than the 5800-3R9 specification (5.8 A). If your application requires saturation current margin above 3.2 A, the 2474-08L is not suitable. Consult your circuit design specifications to determine if this parameter is critical.
