Bourns 9230-08 330nH Unshielded Molded Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-08 is a 330 nH unshielded molded inductor rated for 780 mA with a maximum DC resistance of 200mOhm, designed for through-hole axial mounting. This component operates across a temperature range of -55°C to 105°C and features a phenolic core with ±10% inductance tolerance. The 9230-08 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-08 is determined by the following critical parameters: inductance value (330 nH), inductance tolerance (±10%), current rating capability, DC resistance, mounting type (through hole axial), package dimensions, core material (phenolic), and operating temperature range. Substitute parts must maintain electrical performance within these specified boundaries to ensure functional equivalence in circuit applications.

The substitute parts identified are grouped into two categories:

Direct Equivalent (Same Manufacturer): The 9230-08-RC is manufactured by Bourns Inc. and maintains identical electrical specifications and physical dimensions as the main part. The primary distinction is packaging format (bulk versus standard) and product status (active versus obsolete).

Similar Equivalent (Alternative Manufacturer): The 1025-08K, manufactured by API Delevan Inc., provides functional equivalence with minor parameter variations within acceptable engineering tolerances. This part meets the same inductance, tolerance, and mounting requirements while offering enhanced current rating and extended temperature range.

Parameter Comparison

Engineering Selection Recommendations

9230-08-RC (Bourns Inc.): This part is the preferred direct substitute for the obsolete 9230-08. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. Selection of the 9230-08-RC eliminates obsolescence risk and provides access to current manufacturing processes and quality assurance protocols.

1025-08K (API Delevan Inc.): This part serves as a functional alternative when the 9230-08-RC is unavailable. The 1025-08K provides enhanced current rating capability (830 mA versus 780 mA) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). The DC resistance specification (220mOhm Max) remains within acceptable engineering tolerance relative to the main part. This part is qualified to MIL-PRF-M15305 military standards and is available in cut tape packaging. RoHS compliance status differs from the main part; applications requiring RoHS certification should account for this distinction.

Frequently Asked Questions (FAQ)

Q: Can the 9230-08-RC be used as a direct replacement for the 9230-08?

A: Yes. The 9230-08-RC is electrically and mechanically identical to the 9230-08, with the same inductance (330 nH), current rating (780 mA), DC resistance (200mOhm Max), and physical dimensions (0.095" Dia x 0.250" L). The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant). Direct substitution is appropriate for all applications.

Q: What are the key differences between the 1025-08K and the 9230-08?

A: Both parts share identical inductance (330 nH), tolerance (±10%), Q factor (30 @ 25MHz), self-resonant frequency (410MHz), and physical dimensions. The 1025-08K offers higher current rating (830 mA versus 780 mA) and extended temperature range (-55°C to 125°C versus -55°C to 105°C). The DC resistance is slightly higher (220mOhm Max versus 200mOhm Max). The 1025-08K is manufactured by API Delevan Inc. and meets MIL-PRF-M15305 military specifications.

Q: Are all substitute parts available in the same packaging format?

A: No. The 9230-08 is supplied in standard packaging, the 9230-08-RC is available in bulk packaging, and the 1025-08K is supplied in cut tape (CT) format. Packaging selection should align with production requirements and inventory management protocols.

Q: Which substitute part should be selected for new designs?

A: The 9230-08-RC is the recommended choice for new designs due to its active product status, identical specifications, and ROHS3 compliance. The 1025-08K is suitable when enhanced current rating or extended temperature range is required, or when the 9230-08-RC is unavailable.

Q: Are there RoHS compliance considerations when selecting a substitute?

A: Yes. The 9230-08-RC is ROHS3 compliant, while both the 9230-08 and 1025-08K are RoHS non-compliant. Applications subject to RoHS regulations should prioritize the 9230-08-RC. The 1025-08K may be acceptable in applications where RoHS compliance is not mandated.
