Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-86 is determined by the following critical parameters:

  • Inductance Value: Must be 560 µH ±10%
  • DC Resistance: Must not exceed 46Ohm
  • Core Material: Ferrite construction required
  • Shielding Configuration: Unshielded only
  • Mounting Interface: Through-hole axial package mandatory
  • Physical Envelope: 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
  • Q Factor: 30 @ 790kHz minimum
  • Self Resonant Frequency: 5MHz minimum

The API Delevan 1025-86K meets these core substitution criteria with matching inductance, DCR, core material, shielding, mounting type, and physical dimensions. Current rating differences and operating temperature range variations are secondary considerations when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

The API Delevan 1025-86K qualifies as a direct substitute for the obsolete Bourns 9230-86 based on electrical and mechanical parameter alignment. Both components share identical inductance values, DC resistance specifications, core material composition, and physical form factor. The API Delevan part maintains active product status, ensuring continued availability and supply chain reliability.

The primary design consideration is the current rating differential: the API Delevan 1025-86K is rated for 35 mA versus the Bourns part's 48 mA specification. Circuit designs operating at or below 35 mA can employ the substitute without modification. Applications requiring the full 48 mA capacity must evaluate alternative solutions or confirm that actual operating current remains within the 35 mA limit.

The operating temperature range of the API Delevan part extends to 105°C maximum, compared to the Bourns specification of 125°C. Applications operating above 105°C require thermal analysis to confirm compatibility.

Both components carry identical RoHS non-compliant and REACH Unaffected designations, maintaining regulatory consistency in replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-86K replace the Bourns 9230-86 in all applications?

A: Substitution is valid when circuit operating current does not exceed 35 mA and maximum ambient temperature remains below 105°C. These are the only parameters that differ between the two parts. All other electrical and mechanical specifications are identical.

Q: What is the significance of the current rating difference?

A: The Bourns 9230-86 is rated for 48 mA while the API Delevan 1025-86K is rated for 35 mA. If your circuit operates at 35 mA or below, the substitute performs identically. If your design requires the full 48 mA capacity, the API Delevan part is not suitable without circuit redesign.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.095" diameter by 0.250" length (2.41mm x 6.35mm). They are mechanically interchangeable in through-hole axial mounting applications.

Q: Do both parts have the same inductance and DC resistance?

A: Yes. Both components provide 560 µH inductance with ±10% tolerance and 46Ohm maximum DC resistance. The Q factor and self-resonant frequency are also identical at 30 @ 790kHz and 5MHz respectively.

Q: What is the impact of the operating temperature range difference?

A: The Bourns part operates to 125°C while the API Delevan part operates to 105°C. If your application requires operation above 105°C, the substitute is not suitable. For applications with maximum ambient temperatures at or below 105°C, both parts perform equivalently.

Q: Are there compliance or certification differences?

A: Both parts carry identical RoHS non-compliant and REACH Unaffected designations. No compliance advantage exists between the two components.

Q: Why is the Bourns 9230-86 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The API Delevan 1025-86K remains in active production, providing a viable path for design continuity and component procurement.
