Bourns 5800-183 Equivalent & Substitute Parts

Part Overview

The Bourns 5800-183 is an 18 mH unshielded drum core wirewound inductor rated for 58 mA continuous current with a maximum DC resistance of 41 Ohm. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates across a temperature range of -55°C to 105°C and is designed for through-hole axial mounting applications.

Substitute Part Grouping Explanation

Substitute parts for the 5800-183 are qualified based on the following critical parameters:

Inductance value: 18 mH (exact match required)
Inductance tolerance: ±10% or tighter
Current rating: minimum 58 mA continuous
DC resistance: 41 Ohm or lower
Core material: Ferrite
Shielding: Unshielded
Mounting type: Through Hole Axial
Operating temperature range: must encompass -55°C to 105°C minimum
Test frequency: 1 kHz

Two substitute parts meet these electrical and mechanical criteria: the Bourns 5800-183-RC (direct manufacturer equivalent with updated packaging and compliance) and the API Delevan 2474-52L (alternative manufacturer with enhanced current rating and extended temperature range).

Engineering Selection Recommendations

The Bourns 5800-183-RC is the primary substitute for the obsolete 5800-183. Both parts are manufactured by Bourns Inc., share identical electrical specifications, and maintain the same physical dimensions. The 5800-183-RC is currently in active production status with ROHS3 compliance, making it suitable for new designs and applications requiring regulatory compliance.

The API Delevan 2474-52L serves as an alternative substitute when the primary option is unavailable. This part exceeds the minimum current rating requirement (90 mA versus 58 mA) and extends the operating temperature range to 125°C. However, the inductance tolerance is wider (±15% versus ±10%), and the saturation current is lower (50 mA versus 80 mA). Physical dimensions differ slightly, requiring verification of board layout compatibility. The 2474-52L remains RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 5800-183-RC be used as a direct replacement for the 5800-183?

A: Yes. The 5800-183-RC is electrically and mechanically identical to the 5800-183, with identical inductance, current rating, DC resistance, and physical dimensions. The primary difference is product status (active versus obsolete) and improved RoHS3 compliance.

Q: What are the key differences between the 5800-183-RC and the 2474-52L?

A: The 5800-183-RC maintains exact electrical specifications and physical dimensions of the original part. The 2474-52L offers higher current rating (90 mA) and extended temperature range (-55°C to 125°C) but has wider inductance tolerance (±15%), lower saturation current (50 mA), and slightly different physical dimensions (0.240" Dia x 0.740" L). The 2474-52L uses molded construction versus drum core wirewound.

Q: Are there packaging differences between these substitutes?

A: The 5800-183 is supplied in standard packaging. The 5800-183-RC is supplied in Tray packaging. The 2474-52L is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Can the 2474-52L be used in applications requiring the full 58 mA continuous current?

A: Yes. The 2474-52L is rated for 90 mA continuous current, exceeding the 58 mA requirement. However, note that its saturation current (50 mA) is lower than the original part (80 mA), which may affect performance in applications operating near saturation conditions.

Q: What compliance considerations apply to these substitutes?

A: The 5800-183-RC is ROHS3 compliant, suitable for applications with regulatory compliance requirements. The 2474-52L is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Do physical dimension differences affect PCB compatibility?

A: The 5800-183-RC maintains identical dimensions to the original part (0.275" Dia x 0.700" L). The 2474-52L has slightly different dimensions (0.240" Dia x 0.740" L). Verify board layout and mounting hole spacing before selecting the 2474-52L as a substitute.
