Bourns 5800-391 390µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-391 is a 390 µH unshielded drum core wirewound inductor rated for 400 mA continuous current with 860 mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and is specified for 1 kHz inductance testing. The part is currently obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: inductance value (390 µH), core material (ferrite), shielding configuration (unshielded), mounting type (through-hole axial), and operating temperature range compatibility. Current rating, DC resistance, and saturation current are secondary selection criteria that must support the application's electrical requirements.

The 5800-391 has two identified alternatives:

Direct Equivalent (5800-391-RC): Identical electrical specifications and physical dimensions with improved product status and RoHS3 compliance.

Similar Alternative (2474-32L): Matches inductance and core material with higher current capability but different construction type, tolerance, and saturation characteristics.

Parameter Comparison

Engineering Selection Recommendations

5800-391-RC (Bourns Inc.) is the primary substitute for the obsolete 5800-391. This part maintains identical electrical specifications, physical dimensions, and operating temperature range while offering active product status and RoHS3 compliance. Selection of this part eliminates obsolescence risk and satisfies modern regulatory requirements.

2474-32L (API Delevan Inc.) serves as an alternative where higher current capability (680 mA vs. 400 mA) and lower DC resistance (770 mOhm vs. 860 mOhm) are beneficial. However, this part exhibits lower saturation current (320 mA vs. 600 mA), wider tolerance (±15% vs. ±10%), different construction type (molded vs. wirewound), and slightly different physical dimensions. This part is suitable only when application requirements accommodate these parameter variations.

Frequently Asked Questions (FAQ)

Q: Can 5800-391-RC be used as a direct replacement for 5800-391?

A: Yes. The 5800-391-RC provides identical inductance (390 µH), current rating (400 mA), DC resistance (860 mOhm max), saturation current (600 mA), operating temperature range (-55°C to 105°C), and physical dimensions (0.275" Dia × 0.700" L). The primary advantage is active product status and RoHS3 compliance.

Q: When is 2474-32L appropriate as a substitute?

A: The 2474-32L is suitable when the application can tolerate higher current capability (680 mA), lower DC resistance (770 mOhm), wider inductance tolerance (±15%), and extended operating temperature range (-55°C to 125°C). The lower saturation current (320 mA) and different construction type must be evaluated against specific circuit requirements.

Q: What are the physical dimension differences between substitutes?

A: The 5800-391 and 5800-391-RC share identical dimensions (0.275" Dia × 0.700" L). The 2474-32L has a smaller diameter (0.240" vs. 0.275") and slightly longer length (0.740" vs. 0.700"), which may affect board layout and mechanical clearance.

Q: Are there RoHS compliance considerations?

A: The 5800-391 is RoHS non-compliant. The 5800-391-RC is RoHS3 compliant, making it suitable for applications requiring regulatory compliance. The 2474-32L is RoHS non-compliant.

Q: How do tolerance specifications affect circuit performance?

A: The 5800-391 and 5800-391-RC specify ±10% inductance tolerance, while the 2474-32L specifies ±15%. Applications requiring tighter inductance control should prioritize the ±10% tolerance parts.
