Bourns 9230-38 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-38 is a 5.6 µH unshielded molded inductor rated for 260 mA with a maximum DC resistance of 1.8Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part operates across a temperature range of -55°C to 125°C and is RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-38 is determined by the following critical parameters:

• Inductance Value: Must be 5.6 µH with ±10% tolerance
• DC Resistance: Must not exceed 1.8Ohm maximum
• Shielding Configuration: Must be unshielded
• Mounting Type: Must be through-hole axial
• Physical Dimensions: Must match 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
• Q Factor: Must maintain 50 @ 7.9MHz
• Self Resonant Frequency: Must be within acceptable range (65MHz minimum)

The API Delevan 1025-38K meets these core substitution criteria. However, the current rating differs: the substitute is rated for 195 mA versus the original 260 mA. This represents a reduction in maximum current handling capability and must be evaluated against circuit requirements.

Engineering Selection Recommendations

The API Delevan 1025-38K is an active product with equivalent electrical characteristics to the obsolete Bourns 9230-38 across inductance, DC resistance, Q factor, and self-resonant frequency. Both components are RoHS non-compliant and REACH unaffected.

Key considerations for selection:

• Current Rating Differential: The substitute supports 195 mA maximum versus 260 mA for the original. Circuit current requirements must not exceed 195 mA for direct substitution.
• Temperature Range: The substitute operates to 105°C maximum versus 125°C for the original. Applications requiring operation above 105°C are not suitable for this substitute.
• Core Material: The substitute uses iron core versus ferrite core in the original. This difference may affect frequency response characteristics in specific applications.
• Product Status: The substitute is active and available, whereas the original is obsolete. Procurement of the substitute ensures long-term supply continuity.
• Compliance: Both parts maintain identical RoHS and REACH status.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-38K directly replace the Bourns 9230-38 in all applications?

A: Direct substitution is possible only when circuit current requirements do not exceed 195 mA and operating temperature does not exceed 105°C. If either parameter exceeds these limits, the substitute is not suitable.

Q: What is the significance of the core material difference (ferrite vs. iron)?

A: Core material affects frequency response and loss characteristics. Ferrite cores typically exhibit different Q factor behavior across frequency ranges compared to iron cores. Applications sensitive to frequency-dependent performance should evaluate this difference.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both components are 0.095" diameter by 0.250" length (2.41mm x 6.35mm), ensuring mechanical compatibility in through-hole axial mounting applications.

Q: What compliance certifications apply to both parts?

A: Both the Bourns 9230-38 and API Delevan 1025-38K are RoHS non-compliant and REACH unaffected. ECCN classification is EAR99 for both parts.

Q: Is the inductance tolerance identical?

A: Yes. Both parts maintain ±10% inductance tolerance at the 7.9 MHz test frequency.

Q: What is the maximum operating temperature for each part?

A: The Bourns 9230-38 operates from -55°C to 125°C. The API Delevan 1025-38K operates from -55°C to 105°C. Applications requiring operation above 105°C require the original part or an alternative with higher temperature rating.
