Bourns 9230-54 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-54 is a 27 µH unshielded molded inductor rated for 185 mA with a maximum DC resistance of 4.6Ohm, designed for through-hole axial mounting. This component operates across a temperature range of -55°C to 125°C and features a ferrite core with ±10% inductance tolerance. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-54 is determined by the following critical parameters:

• Inductance Value: Must be 27 µH with ±10% tolerance
• DC Resistance: Maximum 4.6Ohm
• Current Rating: Must support minimum 185 mA continuous operation
• Mounting Configuration: Through-hole axial package only
• Physical Dimensions: 0.095" diameter x 0.250" length (2.41mm x 6.35mm)
• Shielding Type: Unshielded construction
• Operating Temperature: Must cover the required application temperature range

The API Delevan 1025-54K meets the core electrical and mechanical substitution criteria, with the exception of current rating, which is specified at 140 mA versus the original 185 mA rating.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1025-54K is an active product with equivalent electrical specifications and identical physical dimensions to the obsolete Bourns 9230-54. Both components share identical inductance values, tolerance, DC resistance, and Q-factor characteristics at 2.5MHz.

The primary design consideration is the current rating differential: the API Delevan part is rated for 140 mA versus the original 185 mA specification. Applications operating at or below 140 mA continuous current are electrically compatible. Applications requiring the full 185 mA rating must evaluate alternative sources or confirm that the 140 mA rating is sufficient for the specific circuit operation.

Both parts carry identical RoHS non-compliance and REACH unaffected status. The API Delevan component operates to 105°C maximum, compared to the original 125°C upper limit. Applications requiring operation above 105°C require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-54K directly replace the Bourns 9230-54 in all applications?

A: Direct replacement is possible for applications where continuous current does not exceed 140 mA and maximum operating temperature does not exceed 105°C. The inductance value, DC resistance, and physical dimensions are identical. Applications exceeding these current or temperature limits require alternative component evaluation.

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

A: The Bourns 9230-54 uses ferrite core material while the API Delevan 1025-54K uses iron core material. Both achieve the same inductance value and Q-factor at 2.5MHz. Core material differences do not affect substitution eligibility when electrical performance parameters are equivalent.

Q: Are there packaging differences between these components?

A: The Bourns 9230-54 is supplied in standard packaging, while the API Delevan 1025-54K is supplied in Cut Tape (CT) format. Both maintain identical axial through-hole package dimensions of 0.095" diameter x 0.250" length. Tape packaging is standard for active production components and does not affect electrical or mechanical compatibility.

Q: What compliance considerations apply to substitution?

A: Both components are RoHS non-compliant and REACH unaffected. No compliance advantage exists between the original and substitute part. Applications with RoHS compliance requirements must source alternative components meeting RoHS standards.

Q: How do the self-resonant frequency specifications compare?

A: The Bourns 9230-54 specifies 22MHz self-resonant frequency while the API Delevan 1025-54K specifies 20MHz. This 2MHz difference is within normal manufacturing variation for unshielded inductors and does not affect substitution eligibility for standard circuit applications.
