Bourns 5800-820 82µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-820 is a 82 µH unshielded drum core wirewound inductor rated for 900 mA continuous current with a maximum DC resistance of 190 mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance filtering and energy storage in power conversion circuits.

The 5800-820 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5800-820 are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 82 µH (exact match required)
• Inductance tolerance: ±10% or tighter
• Current rating: minimum 900 mA continuous
• DC resistance: 190 mOhm or lower
• Core material: Ferrite
• Shielding: Unshielded
• Mounting type: Through Hole
• Package: Axial
• Operating temperature range: must encompass -55°C to 105°C

Substitution Categories:

Direct Equivalent (Same Manufacturer): The 5800-820-RC is a direct equivalent manufactured by Bourns Inc. with identical electrical specifications and physical dimensions. The primary distinction is packaging format (tray versus bulk) and product status (active versus obsolete).

Similar Substitute (Alternative Manufacturer): The API Delevan 2474-24L provides functional substitution with the same 82 µH inductance value and ferrite core construction. This part operates within compatible electrical parameters with variations in current rating, DC resistance, and tolerance specifications that must be evaluated against circuit requirements.

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The Bourns 5800-820-RC is the recommended direct substitute. It maintains identical electrical specifications and physical dimensions while offering the advantage of active product status and ROHS3 compliance. This part is suitable for new designs and ongoing production of legacy systems without circuit modification.

For Alternative Substitution:

The API Delevan 2474-24L provides functional substitution when the 5800-820-RC is unavailable. This part meets the core inductance and current rating requirements with the following considerations:

• Saturation current (Isat) of 710 mA is lower than the original 1.3 A specification. Circuit designs operating near saturation limits require verification.
• DC resistance of 152 mOhm is lower than the 190 mOhm maximum, resulting in reduced power dissipation.
• Inductance tolerance of ±15% is wider than the original ±10%, affecting circuit performance in precision applications.
• Physical dimensions differ slightly (0.240" Dia x 0.740" L versus 0.275" Dia x 0.700" L), requiring PCB layout verification for through-hole mounting compatibility.
• Extended operating temperature range to 125°C provides additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the 5800-820-RC be used as a direct drop-in replacement for the 5800-820?

A: Yes. The 5800-820-RC is electrically and mechanically identical to the 5800-820, with the same inductance value, current rating, DC resistance, and physical dimensions. The primary difference is packaging format and product status. No circuit modifications are required.

Q: What are the key differences between the Bourns 5800-820-RC and the API Delevan 2474-24L?

A: Both parts share the same 82 µH inductance and ferrite core construction. The API Delevan part has a higher continuous current rating (1.53 A versus 900 mA) and lower DC resistance (152 mOhm versus 190 mOhm). However, its saturation current is lower (710 mA versus 1.3 A), and inductance tolerance is wider (±15% versus ±10%). Physical dimensions also differ slightly. These differences must be evaluated against specific circuit requirements.

Q: Is the API Delevan 2474-24L suitable for circuits designed for the 5800-820?

A: The 2474-24L can function as a substitute in applications where the lower saturation current and wider inductance tolerance are acceptable. Circuits operating at or near the original 900 mA current rating or requiring tight inductance tolerance should be re-evaluated. PCB layout verification is necessary due to dimensional differences.

Q: What is the impact of the wider inductance tolerance (±15%) in the 2474-24L?

A: The ±15% tolerance in the 2474-24L compared to ±10% in the 5800-820 results in greater variation in inductance values across production batches. In precision filtering, resonant, or tuned circuit applications, this wider tolerance may affect circuit performance and require design margin analysis.

Q: Are there RoHS compliance considerations for these parts?

A: The original 5800-820 is RoHS non-compliant. The 5800-820-RC is ROHS3 compliant, making it suitable for applications with RoHS requirements. The API Delevan 2474-24L is RoHS non-compliant. Compliance requirements should be verified against end-application specifications.

Q: Can the 2474-24L be used in high-temperature applications?

A: The 2474-24L operates to 125°C, providing a 20°C margin above the original 5800-820 specification of 105°C. This extended range may be beneficial in thermally demanding environments, though all other electrical parameters must still meet circuit requirements.
