Bourns 5800-150 15µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-150 is a 15µH unshielded drum core wirewound inductor rated for 1.9A continuous current with a maximum DC resistance of 39mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5800-150 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Engineering Selection Recommendations

5800-150-RC (Direct Equivalent - Preferred): The 5800-150-RC is the direct equivalent manufactured by Bourns Inc. It maintains identical electrical specifications (15µH ±10%, 1.9A rating, 39mOhm DCR) and physical dimensions as the obsolete 5800-150. The primary advantage is active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs or production continuity. This part is the recommended first choice for direct replacement.

2474-15L (Similar Substitute - Conditional): The API Delevan 2474-15L provides a 15µH inductance with higher current rating (2.97A) and extended operating temperature range (-55°C to 125°C). The DC resistance specification (40mOhm Max) is marginally higher than the original (39mOhm Max). The core construction differs (molded versus drum core wirewound), and physical dimensions vary slightly. This part is suitable only when the higher current capacity and extended temperature range provide system-level benefits that offset the tolerance and construction differences. Saturation current (1.6A) is lower than the original (3A), requiring evaluation against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5800-150-RC be used as a direct drop-in replacement for the 5800-150?

A: Yes. The 5800-150-RC maintains identical electrical parameters (15µH ±10%, 1.9A, 39mOhm DCR) and physical dimensions (0.275" Dia x 0.700" L). Both are through-hole axial components with ferrite drum core construction. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What are the key differences between the 5800-150-RC and 2474-15L?

A: Both maintain 15µH inductance and ferrite core material. The 2474-15L offers higher continuous current rating (2.97A versus 1.9A) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). However, the 2474-15L has higher inductance tolerance (±15% versus ±10%), marginally higher DCR (40mOhm versus 39mOhm), lower saturation current (1.6A versus 3A), and different core construction (molded versus drum core wirewound). Physical dimensions also differ slightly.

Q: Is the 2474-15L suitable for applications requiring the original 5800-150 specifications?

A: The 2474-15L is suitable only if the application can accommodate the parameter differences. The higher current rating and extended temperature range may be beneficial. However, the lower saturation current (1.6A) and higher inductance tolerance (±15%) must be evaluated against circuit requirements. The marginal DCR increase (1mOhm) is typically negligible in most applications.

Q: What is the impact of the different core construction between the 5800-150 and 2474-15L?

A: The 5800-150 uses drum core wirewound construction, while the 2474-15L uses molded construction. Both are unshielded ferrite designs. The construction difference may affect frequency response characteristics and mechanical robustness, though both are suitable for through-hole axial mounting. Circuit-level performance testing is recommended if frequency response is critical to the application.

Q: Are there packaging considerations when substituting these parts?

A: The 5800-150 and 5800-150-RC are mechanically identical and use the same axial through-hole footprint. The 2474-15L has slightly different physical dimensions (0.240" Dia x 0.740" L versus 0.275" Dia x 0.700" L), which may require PCB layout verification. All three parts are suitable for standard through-hole assembly processes.

Q: What is the RoHS compliance status of these parts?

A: The 5800-150-RC is ROHS3 compliant, making it suitable for applications with regulatory requirements. The original 5800-150 and the 2474-15L are both RoHS non-compliant. For new designs or regulated applications, the 5800-150-RC is the appropriate choice.
