Bourns 9230-22 Equivalent & Substitute Parts

Part Overview

The Bourns 9230-22 is a 1.2 µH unshielded molded inductor rated for 825 mA with a maximum DC resistance of 180mOhm, 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. 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 9230-22 is determined by the following critical parameters:

• Inductance Value: Must be 1.2 µH with ±10% tolerance
• DC Resistance: Must not exceed 180mOhm maximum
• Q Factor: Must maintain 25 @ 7.9MHz
• Self Resonant Frequency: Must be 150MHz
• Mounting Configuration: Must be through-hole axial
• Physical Dimensions: Must match 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
• Shielding: Must be unshielded
• Operating Temperature: Substitute must support minimum -55°C to 105°C range

The API Delevan 1025-22K meets all critical electrical and mechanical parameters. The primary design consideration is the current rating differential: the substitute part is rated for 620 mA versus the original 825 mA. This reduction in current capacity must be evaluated against actual circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1025-22K is an active product with equivalent electrical specifications and identical physical dimensions to the obsolete Bourns 9230-22. Both components share the same inductance value, tolerance, DC resistance maximum, Q factor, and self-resonant frequency. The substitute part is qualified to MIL-PRF-M15305 and MS75084 military standards.

Two design considerations apply:

1. Current Rating: The substitute part supports 620 mA maximum versus 825 mA for the original. Circuit current requirements must not exceed 620 mA for direct substitution.

2. Operating Temperature Upper Limit: The substitute part operates to 105°C maximum versus 125°C for the original. Applications requiring operation above 105°C are not compatible with this substitute.

3. Core Material: The substitute uses iron core versus ferrite core in the original. Both materials achieve the specified electrical performance at the stated frequency.

The API Delevan 1025-22K is suitable for direct substitution in applications where circuit current does not exceed 620 mA and maximum operating temperature does not exceed 105°C.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-22K be used as a direct replacement for the Bourns 9230-22?

A: Direct substitution is possible if circuit current requirements do not exceed 620 mA and maximum operating temperature does not exceed 105°C. The electrical specifications, physical dimensions, and mounting configuration are identical.

Q: What is the significance of the core material difference (ferrite vs. iron)?

A: Both ferrite and iron cores achieve the specified inductance value, DC resistance, Q factor, and self-resonant frequency at the stated test frequency of 7.9 MHz. The core material difference does not affect compatibility for applications within the specified electrical parameters.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS non-compliant and REACH unaffected. The API Delevan 1025-22K carries military qualification to MIL-PRF-M15305 and MS75084, which the Bourns 9230-22 does not specify.

Q: What happens if my circuit requires more than 620 mA?

A: The API Delevan 1025-22K is rated for 620 mA maximum. Operating above this rating may result in inductor saturation and performance degradation. Alternative parts with higher current ratings must be evaluated.

Q: Is the packaging format compatible?

A: Yes. Both parts use through-hole axial mounting with identical physical dimensions of 0.095" diameter by 0.250" length (2.41mm x 6.35mm). PCB layout and assembly processes require no modification.
