Substitute Part Grouping Explanation
Substitution of the Bourns 8230-94 is determined by electrical and mechanical parameter equivalence within the 8230 series. The critical parameters for substitution are:
- Inductance value: 100 nH
- Inductance tolerance: ±10%
- Current rating: 1.1 A minimum
- DC resistance: 70 mOhm maximum
- Core material: Phenolic
- Shielding configuration: Unshielded
- Mounting type: Through hole axial
- Physical dimensions: 0.120" Dia × 0.300" L
The 8230-94-RC maintains identical electrical specifications and physical form factor, qualifying it as a direct substitute. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations
The 8230-94-RC is the direct active equivalent for the obsolete 8230-94. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 8230-94-RC is classified as active product status, ensuring continued availability and supply chain reliability.
The 8230-94-RC achieves ROHS3 compliance, whereas the original 8230-94 is non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 8230-94-RC is the appropriate selection. For legacy systems without compliance requirements, both parts are electrically and mechanically interchangeable.
Frequently Asked Questions (FAQ)
Q: Can the 8230-94-RC replace the 8230-94 in existing designs?
A: Yes. The 8230-94-RC is electrically and mechanically identical to the 8230-94. All electrical parameters, physical dimensions, and mounting characteristics are equivalent. Direct substitution is possible without circuit modification.
Q: What is the primary difference between these parts?
A: The 8230-94 is obsolete, while the 8230-94-RC is active product. The 8230-94-RC also carries ROHS3 compliance certification, whereas the 8230-94 is non-compliant. Electrical and mechanical specifications are identical.
Q: Are there packaging differences between the 8230-94 and 8230-94-RC?
A: The 8230-94 is supplied in standard packaging, while the 8230-94-RC is supplied in bulk packaging. Both maintain the same axial through-hole form factor and physical dimensions.
Q: What parameters must remain constant for substitution within the 8230 series?
A: Inductance (100 nH), inductance tolerance (±10%), current rating (1.1 A), DC resistance (70 mOhm max), core material (phenolic), shielding (unshielded), and physical dimensions (0.120" Dia × 0.300" L) must all remain constant for valid substitution.
Q: Is the 8230-94-RC suitable for RoHS-regulated applications?
A: Yes. The 8230-94-RC is ROHS3 compliant and suitable for applications subject to RoHS directives and customer compliance requirements.
