Bourns 5800-330 33µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5800-330 is a 33µH unshielded drum core wirewound inductor rated for 1.3A continuous current with a maximum DC resistance of 90mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for general-purpose filtering and energy storage applications in electronic circuits.

The 5800-330 is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives with identical or compatible electrical specifications are available from both Bourns Inc. and other manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the 5800-330 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (5800-330-RC): This Bourns part maintains identical electrical specifications including inductance value, current rating, DC resistance, core material, and operating temperature range. The primary difference is product status (active vs. obsolete) and packaging format (tray vs. standard). This part is a direct functional replacement with no design modifications required.

Similar Substitute (2474-19L): This API Delevan part shares the same inductance value (33µH), core material (ferrite), mounting type (through hole), and package style (axial). However, it introduces variations in current rating (2.17A vs. 1.3A), DC resistance (75mOhm vs. 90mOhm), tolerance (±15% vs. ±10%), and operating temperature range (-55°C to 125°C vs. -55°C to 105°C). This part is suitable for applications where the higher current capability and lower DC resistance provide performance benefits, provided circuit design accommodates the tolerance difference.

Engineering Selection Recommendations

For Direct Replacement: The 5800-330-RC is the preferred substitute when component-level compatibility is required. As an active product with ROHS3 compliance, it eliminates obsolescence risk while maintaining identical electrical performance and mechanical fit. This part is suitable for all applications currently using the 5800-330.

For Performance-Enhanced Applications: The 2474-19L offers increased current handling capacity (2.17A vs. 1.3A) and reduced DC resistance (75mOhm vs. 90mOhm), making it suitable for circuits where thermal management or current margin is a design consideration. The extended operating temperature range (-55°C to 125°C) provides additional thermal headroom. However, the ±15% inductance tolerance and different core construction (molded vs. drum core wirewound) require circuit validation to confirm compatibility with existing design margins.

Compliance Considerations: The 5800-330-RC is the only ROHS3-compliant option among the three parts. For applications subject to RoHS regulations, this part is the mandatory selection.

Frequently Asked Questions (FAQ)

Q: Can the 5800-330-RC be used as a direct drop-in replacement for the 5800-330?

A: Yes. The 5800-330-RC maintains identical inductance, current rating, DC resistance, core material, operating temperature range, and physical dimensions. No circuit modifications are required. The primary difference is product status (active vs. obsolete) and packaging format (tray vs. standard).

Q: What are the key differences between the 5800-330 and the 2474-19L?

A: Both parts share the same 33µH inductance value, ferrite core material, unshielded construction, and axial through-hole package. The 2474-19L differs in current rating (2.17A vs. 1.3A), DC resistance (75mOhm vs. 90mOhm), inductance tolerance (±15% vs. ±10%), core construction type (molded vs. drum core wirewound), and operating temperature range (-55°C to 125°C vs. -55°C to 105°C).

Q: Is the 2474-19L suitable for all applications using the 5800-330?

A: The 2474-19L is electrically compatible for applications where the higher current rating and lower DC resistance do not conflict with circuit design. However, the wider inductance tolerance (±15%) may require circuit validation if tight inductance specifications are critical. The different core construction may also affect frequency response characteristics not specified in the provided parameters.

Q: What is the difference between the 5800-330 and 5800-330-RC packaging?

A: The 5800-330 uses standard packaging, while the 5800-330-RC is supplied in tray packaging. Both parts are electrically and mechanically identical. Tray packaging is typically used for automated assembly processes.

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

A: The 5800-330-RC is the recommended selection for new designs. It is an active product with ROHS3 compliance, eliminating obsolescence and regulatory concerns while maintaining full compatibility with the original 5800-330 specification.

Q: Are there any thermal considerations when selecting between these parts?

A: The 2474-19L operates across a wider temperature range (-55°C to 125°C) compared to the 5800-330 and 5800-330-RC (-55°C to 105°C). For applications operating near the upper temperature limit, the 2474-19L provides additional thermal margin. The lower DC resistance of the 2474-19L (75mOhm vs. 90mOhm) also results in reduced resistive heating under load.
