Bourns 5800-103 Equivalent & Substitute Parts

Part Overview

The Bourns 5800-103 is a 10 mH unshielded drum core wirewound inductor rated for 76 mA continuous current with a maximum DC resistance of 24 ohms. 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 5800-103 has reached 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 systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bourns 5800-103 are identified based on the following critical parameters that determine functional equivalence:

• Inductance Value: 10 mH (primary electrical specification)
• Inductance Tolerance: ±10% or tighter
• Current Rating: Minimum 76 mA continuous
• DC Resistance: Maximum 24 ohms
• Core Material: Ferrite
• Shielding: Unshielded
• Mounting Type: Through Hole Axial
• Operating Temperature Range: Minimum -55°C ~ 105°C coverage
• Test Frequency: 1 kHz

Two substitute parts meet these criteria:

1. 5800-103-RC (Bourns Inc.) - Direct manufacturer equivalent with identical electrical and mechanical specifications, differing only in packaging and product status.

2. 2474-49L (API Delevan Inc.) - Similar part with compatible electrical performance within acceptable tolerances, featuring enhanced current rating and extended temperature range, though with different core construction type (molded vs. drum core).

Parameter Comparison

Engineering Selection Recommendations

5800-103-RC is the primary substitute for the obsolete Bourns 5800-103. This part is manufactured by Bourns Inc. and maintains identical electrical specifications, mechanical dimensions, and thermal operating range. The 5800-103-RC is currently in active production status and carries ROHS3 compliance certification, addressing regulatory requirements for new designs and manufacturing processes. Packaging differs (tray vs. bulk), but electrical and mechanical compatibility is complete.

2474-49L (API Delevan Inc.) serves as an alternative substitute when 5800-103-RC availability is constrained. This part maintains the same 10 mH inductance value, ferrite core material, and unshielded axial configuration. The 2474-49L offers a higher continuous current rating (120 mA vs. 76 mA) and extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C). However, the inductance tolerance is wider (±15% vs. ±10%), and the saturation current is lower (60 mA vs. 110 mA). The molded construction differs from the drum core wirewound design of the original part. Selection of 2474-49L requires verification that the wider tolerance and different saturation characteristics are acceptable for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the 5800-103-RC be used as a direct replacement for the 5800-103?

A: Yes. The 5800-103-RC is electrically and mechanically identical to the 5800-103, with the same inductance value, current rating, DC resistance, core material, dimensions, and operating temperature range. The primary differences are product status (active vs. obsolete) and RoHS compliance level. Substitution is direct with no circuit modifications required.

Q: What are the key differences between 5800-103-RC and 2474-49L?

A: Both parts share the same 10 mH inductance and ferrite core material. The 5800-103-RC maintains exact electrical specifications of the original 5800-103, while the 2474-49L offers higher current rating (120 mA) and extended temperature range. However, 2474-49L has wider inductance tolerance (±15%), lower saturation current (60 mA), and different core construction (molded vs. drum core wirewound). Physical dimensions also differ slightly.

Q: Which substitute should be selected for new designs?

A: The 5800-103-RC is the recommended choice for new designs, as it provides exact electrical and mechanical compatibility with the original specification and carries ROHS3 compliance certification. The 2474-49L is suitable only when specific application requirements (higher current capability, extended temperature range) justify the tolerance and saturation current trade-offs.

Q: Are there packaging considerations when substituting these parts?

A: The 5800-103-RC is supplied in tray packaging, while the original 5800-103 was supplied in bulk. The 2474-49L is supplied in bulk packaging. Verify that packaging format is compatible with assembly and handling processes. Electrical and mechanical form factors remain compatible across all three parts for through-hole axial mounting.

Q: What is the impact of the wider inductance tolerance in the 2474-49L?

A: The 2474-49L carries ±15% inductance tolerance compared to ±10% for the 5800-103 and 5800-103-RC. This wider tolerance may affect circuit performance in applications with tight inductance specifications. Evaluate circuit sensitivity to inductance variation before selecting 2474-49L as a substitute.

Q: How do saturation current differences affect substitution?

A: The 5800-103 and 5800-103-RC both have saturation current (Isat) of 110 mA, while the 2474-49L has Isat of 60 mA. Saturation current defines the threshold above which inductance begins to degrade. Applications operating near or above 60 mA may experience inductance loss with the 2474-49L. Verify that circuit peak currents remain below the saturation specification of the selected substitute.
