Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9130-12 is determined by strict equivalence across the following parameters:

• Inductance value: 470 nH with ±10% tolerance
• Current rating: 650 mA minimum
• DC resistance: 350 mOhm maximum
• Core material: Phenolic
• Shielding configuration: Unshielded
• Frequency characteristics: Q factor of 30 @ 25 MHz and self-resonant frequency of 330 MHz
• Operating temperature range: -55°C to 125°C
• Mounting and package: Through-hole axial configuration with 0.095" diameter and 0.250" length

The API Delevan ER1025-12KR meets all specified electrical and mechanical parameters, qualifying as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan ER1025-12KR is a direct substitute for the obsolete Bourns 9130-12. Both components are RoHS non-compliant and REACH unaffected, with identical ECCN and HTSUS classifications. The ER1025-12KR maintains active product status and is available in tape and reel packaging, supporting production environments. The substitute conforms to MIL-PRF-39010/08 military specifications, providing additional qualification documentation for applications requiring military-grade components.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan ER1025-12KR be used as a direct replacement for the Bourns 9130-12?

A: Yes. Both components share identical electrical specifications (470 nH inductance, 650 mA current rating, 350 mOhm maximum DC resistance), frequency characteristics (Q factor of 30 @ 25 MHz, 330 MHz self-resonant frequency), core material (phenolic), and physical dimensions (0.095" diameter x 0.250" length). The through-hole axial package configuration is identical.

Q: What is the primary advantage of selecting the ER1025-12KR over the obsolete 9130-12?

A: The ER1025-12KR maintains active product status with current manufacturing and distribution support. The component is available in standard tape and reel packaging suitable for production assembly. The part qualifies to MIL-PRF-39010/08 military specifications.

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

A: Both components share identical RoHS, REACH, ECCN, and HTSUS classifications. The ER1025-12KR includes military specification qualification (MIL-PRF-39010/08) not specified for the 9130-12.

Q: Does packaging format affect electrical performance?

A: No. The ER1025-12KR tape and reel packaging is a distribution format only and does not alter electrical or mechanical specifications. Component performance remains identical to the original through-hole axial inductor.

Q: Are there any temperature or frequency limitations when substituting?

A: No. Both components operate identically across the -55°C to 125°C temperature range and maintain specified Q factor and self-resonant frequency characteristics across all operating conditions.
