Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9130-80 is determined by strict equivalence across the following critical parameters: inductance value (330 µH), inductance tolerance (±10%), current rating (45 mA), maximum DC resistance (28Ohm), core material (ferrite), shielding configuration (unshielded), frequency characteristics (Q @ 790kHz and self-resonant frequency), operating temperature range (-55°C to 105°C), mounting type (through hole), and package style (axial). The substitute part must maintain identical physical dimensions (0.095" Dia x 0.250" L) to ensure mechanical compatibility in existing PCB layouts.

The API Delevan ER1025-80KR meets all specified electrical and mechanical parameters and qualifies as a direct substitute. This part is manufactured to MIL-PRF-39010/10 military specifications and maintains active product status, providing long-term availability compared to the obsolete Bourns component.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan ER1025-80KR be used as a direct replacement for the Bourns 9130-80?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including inductance (330 µH), current rating (45 mA), DC resistance (28Ohm max), core material (ferrite), operating temperature range (-55°C to 105°C), and physical dimensions (0.095" Dia x 0.250" L). Direct substitution is supported without circuit modification.

Q: What is the primary advantage of selecting the ER1025-80KR over the obsolete 9130-80?

A: The ER1025-80KR maintains active product status and is manufactured to military specifications (MIL-PRF-39010/10), ensuring continued availability and supply chain reliability. The obsolete 9130-80 presents long-term sourcing risk.

Q: Are there packaging differences between these components?

A: The Bourns 9130-80 packaging specification is not provided in available data. The API Delevan ER1025-80KR is supplied in Tape & Reel (TR) packaging, standard for automated assembly operations.

Q: Do both components meet the same compliance requirements?

A: Yes. Both the Bourns 9130-80 and API Delevan ER1025-80KR share identical compliance status: RoHS non-compliant, REACH unaffected, and ECCN EAR99 classification.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching inductance (330 µH ±10%), current rating (45 mA), maximum DC resistance (28Ohm), core material (ferrite), shielding (unshielded), frequency characteristics (Q @ 790kHz and 7MHz self-resonant frequency), and operating temperature range (-55°C to 105°C).
