Key Parameters

Substitute Part Grouping Explanation

The Bourns 8230-12-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Inductance value: 470 nH ±10%
• Current rating: 590 mA minimum
• DC resistance: 350 mOhm maximum
• Core material: Phenolic
• Shielding configuration: Unshielded
• Mounting type: Through hole axial
• Physical dimensions: 0.120" Dia × 0.300" L
• Operating temperature range: -55°C to 105°C minimum
• Self resonant frequency: 340 MHz
• Q factor @ 25 MHz: 30

The 8230-12-RC maintains all specified electrical characteristics and physical form factor, enabling direct replacement in existing designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The 8230-12-RC is the appropriate selection for new designs and procurement of the Bourns 8230 series 470 nH inductor. This part maintains full electrical and mechanical compatibility with the obsolete 8230-12 while offering active product status and ROHS3 compliance. The transition from the non-compliant 8230-12 to the ROHS3-compliant 8230-12-RC aligns with current regulatory requirements and supply chain availability. Both parts share identical inductance, current rating, DC resistance, and thermal specifications, supporting direct substitution in existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the 8230-12-RC replace the 8230-12 in existing designs?

A: Yes. The 8230-12-RC is electrically and mechanically identical to the 8230-12. All critical parameters including inductance, current rating, DC resistance, frequency response, and physical dimensions are equivalent. Direct substitution is supported without circuit redesign.

Q: What is the primary difference between these parts?

A: The 8230-12 is obsolete and non-RoHS compliant, while the 8230-12-RC is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between the two parts?

A: The 8230-12 is supplied in standard packaging, while the 8230-12-RC is supplied in bulk packaging. Both maintain the same axial through-hole form factor and physical dimensions of 0.120" Dia × 0.300" L.

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

A: Substitution compatibility is determined by inductance value (470 nH ±10%), current rating (590 mA), DC resistance (350 mOhm maximum), core material (phenolic), shielding type (unshielded), and operating temperature range (-55°C to 105°C).

Q: Is the 8230-12-RC suitable for high-frequency applications?

A: Yes. The part maintains a self-resonant frequency of 340 MHz and a Q factor of 30 at 25 MHz, supporting applications across the specified frequency range.
