Bourns 9230-10 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-10 is a 390 nH unshielded molded inductor rated for 640 mA with a maximum DC resistance of 300mOhm, 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 continuity. Substitute parts must maintain identical inductance values, equivalent current ratings, matching DC resistance specifications, and compatible physical dimensions to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-10 is determined by strict equivalence across the following parameters:

Inductance Value: Must be 390 nH ±10%
DC Resistance: Must not exceed 300mOhm maximum
Current Rating: Must meet or exceed 640 mA
Shielding Configuration: Must be unshielded
Core Material: Must be phenolic

Engineering Selection Recommendations

The API Delevan 1025-10K is a direct functional substitute for the obsolete Bourns 9230-10. Both components share identical electrical specifications for inductance, tolerance, DC resistance, and quality factor. The API Delevan part provides enhanced current rating capability (710 mA versus 640 mA) and an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), making it suitable for applications requiring higher thermal or current margins.

Both parts carry identical RoHS non-compliance and REACH unaffected status. The API Delevan 1025-10K is classified as an active product with confirmed inventory availability, eliminating procurement risk associated with the obsolete Bourns designation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-10K be used as a direct replacement for the Bourns 9230-10?

A: Yes. Both components have identical inductance (390 nH), tolerance (±10%), DC resistance (300mOhm max), core material (phenolic), shielding (unshielded), and physical dimensions (0.095" Dia x 0.250" L). The API Delevan part exceeds the current rating requirement and operates across a wider temperature range.

Q: What are the key differences between these two parts?

A: The API Delevan 1025-10K has a higher current rating (710 mA versus 640 mA) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). The self-resonant frequency differs slightly (365MHz versus 380MHz), but both values remain within acceptable tolerance for this component class.

Q: Are there any compliance or certification differences?

A: Both parts share identical compliance status: RoHS non-compliant and REACH unaffected. No compliance advantage exists between the two options.

Q: Will the API Delevan part fit in the same PCB footprint?

A: Yes. Both components have identical physical dimensions (0.095" Dia x 0.250" L / 2.41mm x 6.35mm) and use through-hole axial mounting, ensuring mechanical compatibility with existing board layouts.

Q: Why is the Bourns part listed as obsolete?

A: The Bourns 9230-10 has reached end-of-life status. The API Delevan 1025-10K remains in active production, providing long-term procurement stability and availability.
