Bourns 9230-32 Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-32 is a 3.3 µH unshielded molded inductor rated for 380 mA with 850mOhm maximum DC resistance, designed for through-hole axial mounting. This part carries an obsolete product status, making identification of suitable alternatives essential for ongoing production and maintenance applications. The component operates across the temperature range of -55°C to 125°C and is classified as RoHS non-compliant.

Substitute Part Grouping Explanation

Substitute parts for the Bourns 9230-32 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Inductance value: 3.3 µH (exact match required)
• Tolerance: ±10% (exact match required)
• DC Resistance: 850mOhm Max (exact match required)
• Q @ Frequency: 45 @ 7.9MHz (exact match required)
• Self Resonant Frequency: 90MHz (exact match required)
• Mounting Type: Through Hole Axial (exact match required)
• Physical dimensions: 0.095" Dia x 0.250" L (exact match required)
• Shielding: Unshielded (exact match required)

Substitutes are categorized as direct equivalents when all electrical parameters and physical dimensions match precisely. Partial substitutes may differ in current rating, core material, or compliance status while maintaining core electrical performance at the specified test frequency.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 9230-32-RC serves as the direct equivalent substitute, maintaining identical electrical specifications and physical dimensions while offering active product status and ROHS3 compliance. This part is the preferred choice for applications requiring regulatory compliance and long-term availability.

The API Delevan 1025-32K functions as a similar substitute with equivalent inductance, tolerance, DC resistance, and frequency characteristics. However, this part operates at a reduced current rating of 285 mA compared to the 380 mA rating of the main part, and supports a narrower operating temperature range of -55°C to 105°C versus -55°C to 125°C. The 1025-32K features an iron core material and military specification compliance (MIL-PRF-M15305, MS75084). Selection of this part requires confirmation that the application current demand does not exceed 285 mA and that the reduced upper temperature limit is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 9230-32-RC be used as a direct replacement for the 9230-32?

A: Yes. The 9230-32-RC maintains identical inductance (3.3 µH), tolerance (±10%), DC resistance (850mOhm Max), Q factor (45 @ 7.9MHz), self-resonant frequency (90MHz), and physical dimensions (0.095" Dia x 0.250" L). Both parts are manufactured by Bourns Inc. and use ferrite cores. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. non-compliant).

Q: What are the limitations of using the API Delevan 1025-32K as a substitute?

A: The 1025-32K has a maximum current rating of 285 mA, which is 95 mA lower than the 9230-32's 380 mA rating. Additionally, the operating temperature range is limited to -55°C to 105°C, reducing the upper temperature limit by 20°C. The core material differs (iron vs. ferrite). These differences require application-level verification before substitution.

Q: Are there packaging differences between these parts?

A: Yes. The 9230-32 packaging is unspecified. The 9230-32-RC is supplied in Bulk packaging. The 1025-32K is supplied in Cut Tape (CT) packaging. Packaging selection depends on procurement and assembly requirements.

Q: Do all substitute parts share the same physical footprint?

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

Q: Which substitute is recommended for new designs?

A: The 9230-32-RC is recommended for new designs due to its active product status, ROHS3 compliance, and identical electrical and mechanical specifications to the obsolete 9230-32.
