Bourns 5800-151 150µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-151 is a 150 µH unshielded drum core wirewound inductor rated for 600 mA continuous current with a maximum DC resistance of 460mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance values in compact form factors.

The 5800-151 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5800-151 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Inductance value: 150 µH (exact match required)
• Core material: Ferrite (unshielded)
• Mounting type: Through hole axial configuration
• Operating temperature range: Minimum -55°C to 105°C coverage
• Inductance test frequency: 1 kHz

Secondary Compatibility Factors:

• Current rating: Must meet or exceed 600 mA continuous operation
• DC resistance: Lower or equal values preferred to minimize power dissipation
• Physical dimensions: Axial package compatibility with PCB layout constraints
• Saturation current: Must support transient current demands

The substitute parts listed below satisfy the primary matching criteria. Variations in secondary factors reflect different design approaches and manufacturing processes while maintaining functional equivalence for the specified inductance and current requirements.

Engineering Selection Recommendations

5800-151-RC (Direct Substitute - Recommended)

The 5800-151-RC is the primary substitute for the obsolete 5800-151. Both parts are manufactured by Bourns Inc. and share identical electrical specifications: 150 µH inductance, ±10% tolerance, 600 mA current rating, 900 mA saturation current, and 460 mOhm maximum DC resistance. Physical dimensions and mounting characteristics are identical.

The 5800-151-RC maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements for new designs and production runs. This part is the direct replacement when component availability and regulatory compliance are priorities.

2474-27L (Alternative Substitute)

The API Delevan 2474-27L provides an alternative solution with the same 150 µH inductance value and ferrite core construction. This molded inductor design offers a higher continuous current rating of 1.04 A and lower DC resistance of 330 mOhm maximum, providing improved thermal performance in applications approaching the 600 mA design limit.

The 2474-27L operates across an extended temperature range of -55°C to 125°C, supporting applications with elevated ambient temperature requirements. Physical dimensions differ slightly (0.240" Dia x 0.740" L versus 0.275" Dia x 0.700" L), requiring verification of PCB layout compatibility. The ±15% inductance tolerance is broader than the original specification.

Selection between 5800-151-RC and 2474-27L depends on regulatory compliance requirements, thermal performance needs, and physical space constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5800-151-RC be used as a direct replacement for the 5800-151?

A: Yes. The 5800-151-RC is electrically and mechanically identical to the 5800-151, with matching inductance (150 µH), current rating (600 mA), DC resistance (460 mOhm max), and physical dimensions (0.275" Dia x 0.700" L). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What are the key differences between the 5800-151-RC and 2474-27L?

A: Both parts provide 150 µH inductance with ferrite cores and through-hole axial mounting. The 2474-27L offers higher current capacity (1.04 A versus 600 mA), lower DC resistance (330 mOhm versus 460 mOhm), and extended temperature range (-55°C to 125°C versus -55°C to 105°C). Physical dimensions differ slightly, and inductance tolerance is ±15% versus ±10%. The 2474-27L uses molded construction versus drum core wirewound.

Q: Are there physical space considerations when substituting with the 2474-27L?

A: Yes. The 2474-27L dimensions are 0.240" Dia x 0.740" L (6.10mm x 18.80mm) compared to the original 0.275" Dia x 0.700" L (6.99mm x 17.78mm). The diameter is smaller but the length is slightly greater. PCB layout and component placement must be verified to ensure compatibility with the target application.

Q: Which substitute part should be selected for new designs?

A: The 5800-151-RC is recommended for new designs requiring direct compatibility with existing schematics and layouts. It provides identical electrical and mechanical specifications with the advantage of active product status and ROHS3 compliance. The 2474-27L is suitable when improved thermal performance or extended temperature range is required and physical dimensions can be accommodated.

Q: What is the saturation current difference between the 5800-151 and 2474-27L?

A: The 5800-151 has a saturation current (Isat) of 900 mA, while the 2474-27L has an Isat of 520 mA. Applications with transient current demands exceeding 520 mA may require the higher saturation current of the 5800-151 or 5800-151-RC to prevent core saturation.

Q: Are there RoHS compliance implications when selecting a substitute?

A: The 5800-151-RC achieves ROHS3 compliance, making it suitable for applications and markets with RoHS requirements. The 2474-27L is RoHS non-compliant. For new designs subject to RoHS regulations, the 5800-151-RC is the appropriate selection.
