Bourns 5800-122 Equivalent & Substitute Parts

Part Overview

The Bourns 5800-122 is a 1.2 mH unshielded drum core wirewound inductor rated for 230 mA with a maximum DC resistance of 2.7 Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, current rating compatibility, and operating temperature range to ensure functional equivalence in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bourns 5800-122 are classified based on electrical parameter alignment and product availability status. The primary substitution criteria are:

Direct Electrical Equivalence: Inductance value of 1.2 mH, ferrite core material, unshielded construction, and through-hole axial mounting are mandatory matching parameters. Current rating and DC resistance must support the original design specifications without exceeding saturation limits.

Tolerance Considerations: The original part specifies ±10% inductance tolerance. Substitute parts with different tolerance specifications remain functionally compatible provided the inductance value remains within acceptable circuit operating margins.

Temperature Range: Operating temperature range of -55°C to 105°C is the baseline requirement. Substitute parts with extended temperature ranges provide enhanced environmental compatibility.

Product Status Impact: The obsolete status of the 5800-122 necessitates active-status alternatives. RoHS compliance status and packaging format differences do not affect electrical functionality but influence procurement and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

5800-122-RC (Direct Substitute): This part is the primary equivalent for the obsolete 5800-122. It maintains identical electrical specifications, physical dimensions, and operating temperature range. The 5800-122-RC is manufactured by Bourns Inc. and carries active product status with ROHS3 compliance, making it the preferred choice for new designs and production continuity. Packaging format differs (tray versus tape) but does not affect component functionality.

2474-38L (Similar Substitute): The API Delevan 2474-38L provides electrical compatibility with notable parameter variations. While inductance and core material match, this part features a higher current rating (370 mA versus 230 mA) and lower saturation current (180 mA versus 330 mA). The extended operating temperature range (-55°C to 125°C) offers environmental advantages. Physical dimensions differ slightly (0.240" Dia x 0.740" L). This substitute is suitable for applications where the lower saturation current does not present a design constraint and where the higher current rating provides design margin. RoHS non-compliance status matches the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5800-122-RC be used as a direct replacement for the 5800-122?

A: Yes. The 5800-122-RC is electrically and mechanically identical to the 5800-122, with matching inductance (1.2 mH), current rating (230 mA), DC resistance (2.7 Ohm max), and operating temperature range (-55°C to 105°C). The primary difference is product status (active versus obsolete) and packaging format (tray versus tape). Both are through-hole axial components with identical physical dimensions.

Q: What are the key differences between the 5800-122 and the 2474-38L?

A: Both parts share the same inductance value (1.2 mH), ferrite core material, and unshielded axial construction. The 2474-38L differs in current rating (370 mA versus 230 mA), saturation current (180 mA versus 330 mA), inductance tolerance (±15% versus ±10%), operating temperature range (-55°C to 125°C versus -55°C to 105°C), and physical dimensions (0.240" Dia x 0.740" L versus 0.275" Dia x 0.700" L). The 2474-38L is manufactured by API Delevan Inc. rather than Bourns Inc.

Q: Is the 2474-38L suitable for applications requiring the full 230 mA current rating?

A: The 2474-38L has a saturation current of 180 mA, which is lower than the original part's 330 mA saturation current. Applications operating at or near 230 mA may approach saturation limits with the 2474-38L. Circuit design review is necessary to confirm compatibility with the lower saturation specification.

Q: Does RoHS compliance affect component selection?

A: RoHS compliance is a regulatory and procurement consideration rather than an electrical functionality factor. The 5800-122-RC is ROHS3 compliant, while both the original 5800-122 and the 2474-38L are RoHS non-compliant. Selection depends on regulatory requirements for the end application and supply chain compliance mandates.

Q: Are there physical space constraints when substituting the 2474-38L?

A: The 2474-38L has slightly different physical dimensions (0.240" Dia x 0.740" L) compared to the original part (0.275" Dia x 0.700" L). The diameter is smaller but the length is slightly longer. PCB layout and component placement must be verified to ensure the substitute fits within available space constraints.

Q: What is the inductance tolerance impact when using the 2474-38L?

A: The 2474-38L specifies ±15% inductance tolerance compared to the original part's ±10%. This wider tolerance band may affect circuit performance in applications with tight inductance specifications. Circuit simulation or testing should confirm acceptable performance margins with the broader tolerance range.
