Bourns 5800-680 68µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-680 is a 68 µH unshielded drum core wirewound inductor rated for 900 mA continuous current with a maximum DC resistance of 166 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 5800-680 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, field repairs, and design updates where this inductor is specified in existing assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5800-680 are identified based on electrical and mechanical compatibility within the following criteria:

Primary Substitution Criteria:

• Inductance value: 68 µH (exact match required)
• Inductance tolerance: ±10% or tighter
• Current rating: minimum 900 mA continuous
• DC resistance: 166 mOhm or lower
• Core material: Ferrite
• Shielding: Unshielded
• Mounting: Through hole axial configuration
• Operating temperature range: must encompass -55°C to 105°C minimum
• Test frequency: 1 kHz

Substitution Categories:

Direct Equivalent (Same Manufacturer): The 5800-680-RC is an active production variant of the same base product (5800 series) manufactured by Bourns Inc. It maintains identical electrical specifications and physical form factor, with the primary distinction being packaging format and RoHS compliance status.

Similar Substitute (Alternative Manufacturer): The API Delevan 2474-23L provides equivalent inductance and core material with enhanced current handling capability. This part operates within compatible temperature and frequency parameters but exhibits differences in tolerance, DC resistance, and saturation current that must be evaluated for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 5800-680-RC is the recommended substitute for the obsolete 5800-680. Both parts are manufactured by Bourns Inc. and share identical electrical specifications, physical dimensions, and performance characteristics. The 5800-680-RC is in active production status and carries ROHS3 compliance certification, making it suitable for new designs and production continuity. The primary difference is packaging format (tray versus bulk), which does not affect electrical or mechanical compatibility.

For Alternative Substitution:

The API Delevan 2474-23L may be considered when the 5800-680-RC is unavailable. This part meets the core substitution criteria of 68 µH inductance, ferrite core construction, and unshielded axial through-hole configuration. However, the following parameter differences require circuit-level evaluation:

• Inductance tolerance is ±15% versus ±10%, which may impact filter response or resonant frequency calculations
• DC resistance is 145 mOhm (lower than 166 mOhm), reducing power dissipation
• Current saturation is 770 mA, which is below the 900 mA continuous rating of the original part
• Physical dimensions differ slightly (0.240" diameter versus 0.275" diameter), requiring PCB layout verification
• Operating temperature range extends to 125°C, providing additional thermal margin

The 2474-23L is suitable for applications where the 900 mA continuous current requirement can be reduced or where circuit design permits operation below saturation limits.

Frequently Asked Questions (FAQ)

Q: Can the 5800-680-RC be used as a direct drop-in replacement for the 5800-680?

A: Yes. The 5800-680-RC is electrically and mechanically identical to the 5800-680. Both parts have 68 µH inductance, ±10% tolerance, 900 mA current rating, 166 mOhm maximum DC resistance, and identical physical dimensions. The 5800-680-RC is the active production equivalent and is recommended for all applications currently using the obsolete 5800-680.

Q: What are the key differences between the 5800-680-RC and the 2474-23L?

A: The 5800-680-RC and 2474-23L differ in manufacturer, tolerance, DC resistance, saturation current, and physical size. The 5800-680-RC maintains exact electrical specifications of the original part. The 2474-23L offers lower DC resistance and extended temperature range but has wider inductance tolerance (±15%), lower saturation current (770 mA), and different physical dimensions. Selection depends on whether these parameter variations are acceptable for the specific circuit application.

Q: Will the 2474-23L fit in the same PCB footprint as the 5800-680?

A: The 2474-23L has a smaller diameter (0.240" versus 0.275") and slightly longer length (0.740" versus 0.700"). While both are axial through-hole components, the dimensional differences require verification of PCB layout and component spacing. Physical fit must be confirmed before substitution.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 5800-680-RC carries ROHS3 compliance certification, indicating it meets current environmental and material restriction standards. The 5800-680 and 2474-23L are RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the 5800-680-RC is the appropriate choice.

Q: Can the 2474-23L handle the full 900 mA continuous current of the original specification?

A: The 2474-23L is rated for 1.56 A continuous current, which exceeds the 900 mA requirement. However, its saturation current is 770 mA, which is below the 900 mA specification. This means the inductor will saturate at 770 mA, reducing inductance and increasing core losses. The 2474-23L is suitable only for applications where continuous current remains below 770 mA or where saturation effects are acceptable.

Q: Are there any frequency-dependent considerations for these inductors?

A: All three parts are tested and specified at 1 kHz. For applications operating at significantly different frequencies, the inductance value and Q factor may vary. The provided specifications apply to the 1 kHz test frequency. Performance at other frequencies should be verified using manufacturer datasheets or impedance measurements.
