Bourns 9230-30 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-30 is a 2.7 µH unshielded molded inductor rated for 495 mA with a maximum DC resistance of 500mOhm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. Substitute parts must maintain the same inductance value, tolerance, and core electrical characteristics while accommodating variations in current rating and DC resistance within acceptable operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-30 is determined by the following critical parameters:

Primary Matching Criteria:

  • Inductance value: 2.7 µH (exact match required)
  • Tolerance: ±10% (must match or be tighter)
  • Shielding: Unshielded (must match)
  • Mounting type: Through Hole (must match)
  • Package / Case: Axial (must match)
  • Physical dimensions: 0.095" Dia x 0.250" L (2.41mm x 6.35mm) (must match)

Secondary Compatibility Parameters:

  • Current Rating: Substitute must meet or exceed the application requirement; lower ratings indicate reduced current capacity
  • DC Resistance: Substitute values within ±10% of the main part are acceptable for most applications
  • Operating Temperature Range: Substitute range must encompass the application's operating conditions
  • Q @ Frequency and Self Resonant Frequency: Must remain consistent for RF and high-frequency applications

The API Delevan 1025-30K qualifies as a substitute based on matching inductance, tolerance, shielding, mounting type, package, and physical dimensions. However, the reduced current rating (355 mA vs. 495 mA) and slightly higher DCR (550mOhm vs. 500mOhm) represent trade-offs that must be evaluated against specific application requirements.

Engineering Selection Recommendations

The API Delevan 1025-30K is an active product suitable for applications where the Bourns 9230-30 is no longer available. Both components share identical inductance, tolerance, shielding configuration, and physical form factor, establishing functional equivalence for circuit topology and PCB layout purposes.

Selection of the 1025-30K requires evaluation of two specific deviations:

Current Rating Consideration: The 1025-30K is rated for 355 mA maximum current, compared to 495 mA for the 9230-30. Applications operating at currents exceeding 355 mA will exceed the substitute part's rating and require alternative solutions.

DC Resistance Consideration: The 1025-30K exhibits a maximum DCR of 550mOhm versus 500mOhm for the original part. This 50mOhm increase represents a 10% rise in resistive losses. In power-sensitive applications, this may result in measurable increases in heat dissipation and should be factored into thermal design calculations.

Operating Temperature Range: The 1025-30K operates to 105°C maximum, compared to 125°C for the 9230-30. Applications requiring operation above 105°C cannot use this substitute.

Compliance Status: Both components are RoHS non-compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory consistency in procurement and supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-30K be used as a direct replacement for the Bourns 9230-30 in all applications?

A: No. The 1025-30K is suitable only for applications where circuit current does not exceed 355 mA, operating temperature remains below 105°C, and the additional 50mOhm DCR does not compromise system performance. Applications exceeding these parameters require alternative solutions.

Q: What is the significance of the different core materials (Ferrite vs. Iron)?

A: The Bourns 9230-30 uses ferrite core material, while the API Delevan 1025-30K uses iron core material. Both achieve the same inductance value and Q factor at the specified frequency, indicating equivalent electromagnetic performance for the stated electrical parameters.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.095" diameter by 0.250" length (2.41mm x 6.35mm), ensuring identical PCB footprint and mechanical fit in through-hole applications.

Q: How does the packaging difference (bulk vs. Tape & Reel) affect substitution?

A: Packaging format does not affect electrical or mechanical compatibility. The Tape & Reel packaging of the 1025-30K is a supply chain consideration and does not impact circuit performance or board assembly.

Q: What should be done if the application requires operation above 105°C or at currents exceeding 355 mA?

A: Alternative substitute parts with higher current ratings or extended temperature ranges must be identified. The 1025-30K does not meet these requirements and cannot be used in such applications.

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

A: Both components share identical RoHS status (non-compliant), ECCN (EAR99), and HTSUS classifications (8504.50.8000). No compliance advantage exists between the two parts.
