Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5800-8R2 is determined by the following critical parameters:

• Inductance Value: Must be 8.2 µH (tolerance variations acceptable within engineering limits)
• Core Material: Ferrite construction required for electromagnetic performance
• Shielding Configuration: Unshielded topology must be maintained
• Mounting Interface: Through-hole axial package required for PCB compatibility
• Current Handling: Substitute must support minimum 2.2 A continuous current rating
• DC Resistance: Lower or equivalent DCR values are acceptable; higher values may impact circuit performance
• Operating Temperature: Substitute must cover or exceed the -55°C to 105°C range

The API Delevan 2474-12L meets these substitution criteria while offering improved electrical characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2474-12L is a direct functional substitute for the Bourns 5800-8R2 based on the following engineering criteria:

Electrical Compatibility: Both components provide 8.2 µH inductance with ferrite core construction and unshielded topology. The 2474-12L offers superior current handling capacity (4.65 A versus 2.2 A) and lower DC resistance (28 mOhm versus 31 mOhm), making it suitable for applications where the original part is specified.

Mechanical Compatibility: Both inductors feature through-hole axial mounting and are designed for standard PCB assembly processes. Physical dimensions are comparable, with the 2474-12L measuring 0.240" diameter × 0.740" length versus the 5800-8R2 at 0.275" diameter × 0.700" length.

Product Status: The 2474-12L is classified as active, ensuring ongoing availability and supply chain support. The 5800-8R2 is obsolete, making substitution necessary for continued production.

Compliance: Both components carry identical RoHS non-compliant and REACH unaffected designations, maintaining regulatory consistency in system design.

Temperature Performance: The 2474-12L extends the upper operating temperature limit to 125°C, providing additional thermal margin compared to the 5800-8R2 specification of 105°C.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2474-12L be used as a direct replacement for the Bourns 5800-8R2?

A: Yes. Both components share identical inductance values (8.2 µH), ferrite core material, unshielded configuration, and through-hole axial mounting. The 2474-12L meets or exceeds all critical electrical parameters of the 5800-8R2.

Q: What are the differences in current rating between these inductors?

A: The 2474-12L is rated for 4.65 A continuous current, compared to 2.2 A for the 5800-8R2. This higher rating provides additional design margin and allows the substitute to handle increased current loads without saturation or thermal stress.

Q: How do the DC resistance values compare?

A: The 2474-12L has a maximum DC resistance of 28 mOhm, which is lower than the 5800-8R2 specification of 31 mOhm. Lower DCR reduces resistive losses and heat generation in the inductor, improving overall circuit efficiency.

Q: Are there physical dimension differences that affect PCB layout?

A: The 2474-12L measures 0.240" diameter × 0.740" length, while the 5800-8R2 measures 0.275" diameter × 0.700" length. The substitute is slightly narrower and longer. Verify PCB footprint spacing and component clearances before substitution.

Q: What is the inductance tolerance difference?

A: The 5800-8R2 has ±10% tolerance, while the 2474-12L has ±15% tolerance. For applications requiring tighter inductance control, the original specification should be evaluated. For most general-purpose applications, the ±15% tolerance is acceptable.

Q: Do both inductors have the same operating temperature range?

A: No. The 5800-8R2 operates from -55°C to 105°C, while the 2474-12L operates from -55°C to 125°C. The substitute provides extended high-temperature performance, beneficial for thermal-constrained applications.

Q: Are there compliance or regulatory differences?

A: Both components are RoHS non-compliant and REACH unaffected. No regulatory advantage exists between the two parts in terms of environmental compliance.
