Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9130-10 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 390 nH with ±10% tolerance
• Current rating: 700 mA minimum
• DC resistance: 300 mOhm maximum
• Q factor: 30 @ 25 MHz
• Self resonant frequency: 365 MHz
• Operating temperature range: -55°C to 125°C
• Core material: Phenolic
• Shielding configuration: Unshielded
• Mounting and package: Through-hole axial

The API Delevan ER1025-10KR meets all specified electrical and mechanical parameters and qualifies as a direct substitute. This part is manufactured to MIL-PRF-39010/08 military specifications and maintains active product status, providing long-term availability advantages over the obsolete Bourns part.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan ER1025-10KR is the qualified substitute for the Bourns 9130-10. Selection is based on:

• Complete electrical parameter equivalence across inductance, current rating, DC resistance, Q factor, and frequency characteristics
• Identical mechanical and thermal specifications
• Active product status ensuring continued availability and supply chain stability
• Compliance with MIL-PRF-39010/08 military specifications, providing additional qualification documentation
• Matching regulatory classifications (RoHS non-compliant, REACH Unaffected, ECCN EAR99)

Both parts carry identical HTSUS classification (8504.50.8000), confirming functional and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan ER1025-10KR be used as a direct replacement for the Bourns 9130-10?

A: Yes. The ER1025-10KR meets all electrical and mechanical specifications of the 9130-10, including inductance value, current rating, DC resistance, Q factor, frequency response, temperature range, and physical dimensions. Both parts are unshielded phenolic-core axial inductors with identical through-hole mounting.

Q: What is the primary advantage of switching to the API Delevan part?

A: The ER1025-10KR maintains active product status, whereas the Bourns 9130-10 is obsolete. Active status ensures long-term availability, consistent manufacturing, and supply chain reliability.

Q: Are there packaging differences between these parts?
