Bourns 9220-24 820µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9220-24 is a 820 µH unshielded drum core wirewound inductor rated for 81 mA with a maximum DC resistance of 15.1 Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. The 9220-24 operates across the temperature range of -55°C to 105°C and is RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9220-24 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 820 µH with ±5% tolerance
• DC resistance: 15.1 Ohm maximum
• Current rating: minimum 81 mA
• Operating temperature range: -55°C to 105°C
• Mounting configuration: Through-hole axial package
• Shielding classification: Unshielded

The API Delevan 2500-24J meets these substitution criteria. While the core material differs (iron molded versus ferrite drum core) and the current rating is higher (92 mA versus 81 mA), the electrical performance parameters—inductance, tolerance, DC resistance, and operating temperature—remain equivalent. The substitute part is active in production, addressing the obsolescence status of the original component.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2500-24J is the qualified substitute for the obsolete Bourns 9220-24. Selection is based on:

• Electrical parameter equivalence across inductance, tolerance, DC resistance, and operating temperature range
• Current rating of 92 mA exceeds the original 81 mA specification, providing operational margin
• Active product status ensures availability and production continuity
• Identical RoHS non-compliance status maintains regulatory consistency with legacy designs
• Through-hole axial package compatibility with existing PCB layouts

Physical dimensions differ between the two parts (0.190" Dia × 0.440" L for the 9220-24 versus 0.240" Dia × 0.740" L for the 2500-24J). PCB layout verification is required to confirm mechanical fit within the available board space.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-24J directly replace the Bourns 9220-24 in all applications?

A: The 2500-24J meets all electrical parameter requirements for substitution. However, the larger physical dimensions (0.240" Dia × 0.740" L versus 0.190" Dia × 0.440" L) require verification of available PCB mounting space before implementation.

Q: What is the significance of the different core materials (ferrite drum core versus iron molded)?

A: Both core materials deliver the specified 820 µH inductance with ±5% tolerance and 15.1 Ohm DC resistance. The core material difference does not affect the electrical performance parameters that define substitution equivalence for this application.

Q: Why is the current rating of the substitute part (92 mA) higher than the original (81 mA)?

A: The higher current rating of the 2500-24J provides additional operational margin and does not compromise compatibility. The substitute part remains suitable for circuits designed for the original 81 mA specification.

Q: Are there packaging differences between these parts?

A: The Bourns 9220-24 is supplied as individual components, while the API Delevan 2500-24J is available in Tape & Reel (TR) packaging. Both are through-hole axial components suitable for manual or automated assembly.

Q: What compliance considerations apply to both parts?

A: Both the Bourns 9220-24 and API Delevan 2500-24J are RoHS non-compliant and REACH unaffected. Designs using these components maintain consistent regulatory status across the substitution.
