Bourns 9220-08 Equivalent & Substitute Parts

Part Overview

The Bourns 9220-08 is a 390 µH unshielded drum core wirewound inductor rated for 100 mA with 10Ohm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and features a ferrite core construction. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9220-08 is determined by the following critical parameters:

• Inductance value: 390 µH (exact match required)
• Tolerance: ±5% (matching specification)
• DC Resistance: 10Ohm maximum (equal or lower acceptable)
• Current Rating: minimum 100 mA (equal or higher acceptable)
• Operating Temperature: -55°C to 105°C (matching or wider range acceptable)
• Mounting Type: Through Hole Axial (form factor compatibility)
• Shielding: Unshielded (electromagnetic environment compatibility)

The API Delevan 2500-08J meets all substitution criteria with equivalent electrical performance and compatible physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2500-08J is a direct functional substitute for the obsolete Bourns 9220-08. Selection is based on the following engineering factors:

• Both components maintain identical inductance (390 µH) and tolerance (±5%)
• The API Delevan part provides equal DC resistance specification (10Ohm maximum)
• Current rating of 114 mA exceeds the original 100 mA requirement, providing operational margin
• Operating temperature range is identical (-55°C to 105°C)
• Both components are unshielded with equivalent self-resonant frequency (4.5 MHz)
• The API Delevan 2500-08J is currently active in production, ensuring long-term availability
• Both components share RoHS non-compliant and REACH unaffected status
• Physical form factor is compatible for through-hole axial mounting applications

Core material differs (ferrite versus iron) and construction type differs (drum core wirewound versus molded), but these differences do not affect electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-08J directly replace the Bourns 9220-08 in existing designs?

A: Yes. Both components meet identical electrical specifications for inductance, tolerance, DC resistance, current rating, and operating temperature. Through-hole axial mounting is compatible. Physical dimensions differ slightly, but both fit standard component spacing.

Q: Why does the API Delevan part have a higher current rating (114 mA vs 100 mA)?

A: Higher current ratings indicate greater thermal margin and are acceptable for substitution. The circuit will operate within safe parameters with the substitute component.

Q: What is the difference between ferrite and iron core construction?

A: Both core materials are provided in the specifications. Ferrite cores are used in the original Bourns design, while iron cores are used in the API Delevan substitute. Both achieve the required 390 µH inductance and 4.5 MHz self-resonant frequency within the specified tolerance.

Q: Are there packaging differences between these components?

A: The Bourns 9220-08 is supplied in bulk packaging, while the API Delevan 2500-08J is supplied in Tape & Reel (TR) format. Both are through-hole axial components suitable for manual or automated assembly.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS non-compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8504.50.8000 HTSUS code.

Q: Why is the Bourns 9220-08 obsolete?

A: Product obsolescence is determined by the manufacturer. The API Delevan 2500-08J provides equivalent electrical and mechanical performance for applications requiring 390 µH inductance with 100 mA current capability.
