Bourns 9230-80 330µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-80 is a 330 µH unshielded molded inductor rated for 62 mA with 28Ohm maximum DC resistance, designed for through-hole axial mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is suitable for applications requiring ferrite core inductors with stable performance at 790 kHz test frequency.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-80 is determined by the following critical parameters: inductance value (330 µH), tolerance (±10%), DC resistance (28Ohm maximum), core material (ferrite), shielding type (unshielded), mounting configuration (through-hole axial), and physical dimensions (0.095" Dia x 0.250" L).

The substitute parts are categorized as follows:

Direct Equivalent (Same Manufacturer): The Bourns 9230-80-RC maintains identical electrical specifications and physical form factor. The primary distinction is product status (active versus obsolete) and RoHS compliance level.

Similar Substitute (Different Manufacturer): The API Delevan 1025-80K shares the same inductance, tolerance, DCR, core material, shielding, mounting type, and physical dimensions. The current rating differs (45 mA versus 62 mA), and the maximum operating temperature is reduced to 105°C.

Parameter Comparison

Engineering Selection Recommendations

Bourns 9230-80-RC is the primary substitute for the obsolete Bourns 9230-80. Both parts are manufactured by Bourns Inc. and maintain identical electrical and mechanical specifications. The 9230-80-RC is currently in active production status with ROHS3 compliance, making it suitable for new designs and production environments requiring regulatory adherence. This part is a direct replacement with no derating considerations.

API Delevan 1025-80K serves as an alternative substitute when the Bourns 9230-80-RC is unavailable. This part maintains the same inductance, tolerance, DCR, core material, shielding configuration, and physical form factor. However, the current rating is reduced to 45 mA (compared to 62 mA), and the maximum operating temperature is limited to 105°C (compared to 125°C). Selection of this part requires verification that the application current does not exceed 45 mA and that the operating temperature remains within the -55°C to 105°C range.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 9230-80-RC be used as a direct replacement for the Bourns 9230-80?

A: Yes. The 9230-80-RC is a direct equivalent with identical inductance (330 µH), current rating (62 mA), DC resistance (28Ohm), core material (ferrite), shielding (unshielded), and physical dimensions (0.095" Dia x 0.250" L). The primary difference is product status and RoHS compliance level.

Q: Under what conditions can the API Delevan 1025-80K be substituted?

A: The 1025-80K can be substituted when the application current requirement does not exceed 45 mA and the operating temperature remains within -55°C to 105°C. All other electrical parameters (inductance, tolerance, DCR, core material, shielding, Q factor, and self-resonant frequency) are equivalent to the original part.

Q: What is the impact of the reduced current rating on the API Delevan 1025-80K?

A: The 1025-80K is rated for 45 mA maximum current, compared to 62 mA for the Bourns 9230-80. If the application requires current above 45 mA, the 1025-80K will not be suitable. The DC resistance remains 28Ohm maximum for both parts.

Q: Are there temperature range differences between the substitute parts?

A: Yes. The Bourns 9230-80 and 9230-80-RC operate from -55°C to 125°C, while the API Delevan 1025-80K operates from -55°C to 105°C. Applications requiring operation above 105°C must use the Bourns parts.

Q: Do the substitute parts have the same physical dimensions?

A: Yes. All three parts share identical axial package dimensions of 0.095" Dia x 0.250" L (2.41mm x 6.35mm), ensuring mechanical compatibility in through-hole mounting applications.

Q: What is the difference in RoHS compliance between these parts?

A: The Bourns 9230-80-RC is ROHS3 compliant, while both the original Bourns 9230-80 and API Delevan 1025-80K are RoHS non-compliant. Applications subject to RoHS regulations should specify the 9230-80-RC.
