Bourns 5800-821 Equivalent & Substitute Parts

Part Overview

The Bourns 5800-821 is a 820 µH unshielded drum core wirewound inductor rated for 280 mA with a maximum DC resistance of 1.9Ohm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5800-821 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5800-821 is determined by the following critical parameters:

• Inductance Value: Must be 820 µH (primary functional requirement)
• Core Material: Ferrite (electrical performance characteristic)
• Shielding Configuration: Unshielded (electromagnetic compatibility requirement)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Axial (form factor and PCB layout compatibility)
• Current Rating: Must meet or exceed 280 mA (operational safety margin)
• DC Resistance: Must not exceed 1.9Ohm (power dissipation and circuit performance)
• Operating Temperature Range: Must encompass or exceed -55°C to 105°C (environmental compatibility)

The API Delevan 2474-36L meets all substitution criteria. While it employs a molded construction type rather than drum core, both designs utilize ferrite cores and deliver equivalent electrical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2474-36L is a direct functional substitute for the obsolete Bourns 5800-821. Both components share identical inductance values, ferrite core construction, unshielded configuration, and through-hole axial packaging.

The 2474-36L provides superior current handling capacity (420 mA versus 280 mA) and an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). DC resistance remains within acceptable limits at 1.98Ohm maximum, compared to 1.9Ohm for the original part.

The 2474-36L is currently in active production status, ensuring long-term availability and supply chain stability. Both components carry equivalent RoHS non-compliance and REACH unaffected certifications.

Physical dimensions differ slightly; the 2474-36L features a smaller diameter (0.240" versus 0.275") and marginally increased length (0.740" versus 0.700"). These dimensional variations require PCB layout verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2474-36L directly replace the Bourns 5800-821 in existing designs?

A: The 2474-36L meets all electrical substitution criteria. However, dimensional differences require PCB layout verification. The smaller diameter and slightly increased length may affect board space allocation and component placement.

Q: What is the significance of the inductance tolerance difference (±10% versus ±15%)?

A: The original Bourns part specifies tighter tolerance at ±10%, while the substitute allows ±15%. Applications requiring strict inductance accuracy must account for this wider tolerance band in circuit design calculations.

Q: Why does the substitute part have a higher current rating?

A: The API Delevan 2474-36L is rated for 420 mA compared to the original 280 mA. This higher rating provides additional operational margin and does not negatively impact compatibility. The circuit will operate safely within the original 280 mA design specification.

Q: Are there any compliance or certification differences between these parts?

A: Both components carry identical RoHS non-compliance and REACH unaffected certifications. No compliance advantages or disadvantages exist between the two parts.

Q: What construction differences exist between drum core and molded inductor types?

A: The Bourns 5800-821 uses drum core construction, while the API Delevan 2474-36L employs molded construction. Both designs utilize ferrite cores and deliver equivalent electrical performance for this application. Molded construction typically provides improved mechanical robustness and environmental protection.

Q: Is the extended temperature range of the substitute part beneficial?

A: The 2474-36L operates to 125°C versus 105°C for the original part. This extended range provides additional thermal margin and is beneficial for applications operating in elevated temperature environments. It does not negatively impact designs operating within the original -55°C to 105°C range.
