Bourns 9230-42 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-42 is an 8.2 µH unshielded molded inductor rated for 210 mA with a maximum DC resistance of 2.7 Ohm, 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 9230-42 is determined by the following critical parameters:

• Inductance Value: Must be 8.2 µH with ±10% tolerance
• DC Resistance: Must not exceed 2.7 Ohm maximum
• Current Rating: Substitute must support minimum 210 mA operation
• Frequency Characteristics: Q factor of 55 @ 7.9 MHz and self-resonant frequency of 55 MHz
• Physical Form Factor: Axial through-hole mounting with 0.095" diameter and 0.250" length
• Shielding Configuration: Unshielded design

The API Delevan 1025-42K meets the core electrical specifications (inductance, tolerance, DC resistance, frequency characteristics, and physical dimensions) but operates at a reduced current rating of 160 mA and a narrower temperature range of -55°C to 105°C. This part is suitable as a substitute in applications where the 160 mA current limit is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1025-42K is an active product with current manufacturing support, providing supply chain continuity for the obsolete Bourns 9230-42. Both parts share identical inductance, tolerance, DC resistance, and frequency characteristics. The substitute is suitable for applications operating at or below 160 mA. Designs requiring the full 210 mA current rating of the original part must evaluate alternative inductors with higher current specifications. Both parts maintain RoHS non-compliant status and are subject to identical trade classifications (ECCN: EAR99, HTSUS: 8504.50.8000).

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-42K directly replace the Bourns 9230-42 in all applications?

A: The 1025-42K is suitable for applications where circuit current does not exceed 160 mA. If your design requires the full 210 mA rating of the original part, the substitute is not appropriate without circuit redesign.

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

A: The primary differences are current rating (210 mA vs. 160 mA) and maximum operating temperature (125°C vs. 105°C). All other electrical and physical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.095" diameter by 0.250" length axial through-hole components and are mechanically interchangeable.

Q: What is the packaging difference?

A: The Bourns 9230-42 is supplied in standard packaging, while the API Delevan 1025-42K is supplied in Tape & Reel format. This does not affect electrical performance or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS non-compliant and REACH unaffected. They share identical trade classifications and regulatory status.
