Engineering Selection Recommendations

The 8230-48-RC provides functional equivalence to the 8230-48 across all electrical and mechanical parameters. Selection between these parts should be based on the following factors:

Product Status: The 8230-48-RC carries active product status, ensuring ongoing manufacturer support and availability. The 8230-48 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The 8230-48-RC meets ROHS3 compliance requirements, while the 8230-48 is non-compliant. For applications subject to RoHS directives or customer compliance mandates, the 8230-48-RC is the appropriate selection.

Packaging: The 8230-48-RC is supplied in bulk packaging, whereas the 8230-48 uses standard packaging. Bulk packaging may offer cost advantages for high-volume procurement.

Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining equivalent export and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 8230-48-RC be used as a direct replacement for the 8230-48?

A: Yes. The 8230-48-RC maintains identical inductance (15 µH), current rating (205 mA), DC resistance (2.8Ohm maximum), frequency characteristics, and physical dimensions. Both components are through-hole axial inductors with ferrite drum cores and unshielded construction. Electrical and mechanical compatibility is complete.

Q: What is the difference between the 8230-48 and 8230-48-RC?

A: The primary differences are product status and compliance. The 8230-48-RC is an active product with ROHS3 compliance, while the 8230-48 is obsolete and RoHS non-compliant. The 8230-48-RC is supplied in bulk packaging. All electrical and mechanical specifications are identical.

Q: Does the packaging difference affect circuit performance?

A: No. Bulk packaging is a supply and logistics consideration only. It does not affect component electrical performance, frequency response, temperature rating, or mechanical fit within the circuit.

Q: Are there inventory considerations when selecting between these parts?

A: The 8230-48 has 1146 pieces in stock, while the 8230-48-RC has 1882 pieces available. For ongoing production or legacy system support, the 8230-48-RC's active status and higher inventory provide greater supply security.

Q: What are the critical parameters for substitution within the 8230 series?

A: Substitution requires matching inductance value, tolerance, current rating, DC resistance, core material, shielding type, frequency characteristics, operating temperature range, and physical dimensions. Any deviation in these parameters requires separate electrical and mechanical validation.
