Bourns 9220-04 Equivalent & Substitute Parts

Part Overview

The Bourns 9220-04 is a 330 µH unshielded drum core wirewound inductor rated for 105 mA with a maximum DC resistance of 9.1 Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and features a ferrite core construction. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the Bourns 9220-04 is determined by the following critical parameters:

  • Inductance Value: 330 µH (exact match required)
  • Tolerance: ±5% (must match or be tighter)
  • DC Resistance: 9.1 Ohm maximum (must not exceed)
  • Current Rating: Minimum 105 mA (equal or higher acceptable)
  • Shielding: Unshielded (must match)
  • Operating Temperature Range: -55°C to 105°C (must encompass or match)
  • Mounting Type: Through Hole (must match)
  • Package Type: Axial (must match)

The API Delevan 2500-04J meets all substitution criteria. While it employs a molded core construction (versus drum core) and iron core material (versus ferrite), these design differences do not violate the electrical and mechanical parameter constraints. The substitute part delivers equivalent inductance, tolerance, DC resistance, and operating temperature specifications while providing a higher current rating of 120 mA.

Engineering Selection Recommendations

The API Delevan 2500-04J is a direct functional substitute for the obsolete Bourns 9220-04 based on electrical parameter equivalence. Both components are RoHS non-compliant and REACH unaffected, with identical compliance classifications.

The primary consideration for selection is physical footprint. The API Delevan substitute is larger in both diameter and length, requiring verification of available board space in the target application. The increased current rating of 120 mA provides additional design margin compared to the original 105 mA specification.

Both parts maintain identical inductance, tolerance, DC resistance, and operating temperature specifications, ensuring electrical compatibility in circuits designed for the original component.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-04J be used as a direct replacement for the Bourns 9220-04?

A: Yes, from an electrical standpoint. The substitute part meets all critical electrical parameters: 330 µH inductance, ±5% tolerance, 9.1 Ohm maximum DC resistance, and -55°C to 105°C operating temperature. Physical board space must be verified, as the substitute is larger.

Q: What is the difference between drum core and molded construction?

A: The Bourns 9220-04 uses drum core construction with ferrite material, while the API Delevan 2500-04J uses molded construction with iron core material. Both achieve the specified electrical characteristics within the defined parameters.

Q: Does the higher current rating of the substitute part affect compatibility?

A: No. A higher current rating indicates the substitute can safely handle equal or greater current levels. In applications requiring 105 mA, the 120 mA rated substitute provides additional thermal margin.

Q: Are there packaging differences between these parts?

A: The Bourns 9220-04 is supplied as individual components, while the API Delevan 2500-04J is supplied in Tape & Reel (TR) packaging. Both are through-hole axial components suitable for manual or automated assembly.

Q: What should be verified before implementing this substitution?

A: Confirm available PCB space accommodates the larger physical dimensions of the substitute part (0.240" diameter x 0.740" length versus 0.190" diameter x 0.440" length). Verify the application does not depend on specific core material properties beyond the provided electrical specifications.
