Procurement Notes

This part number is officially classified as obsolete by the manufacturer and is not recommended for new designs. Availability is limited to existing stock or secondary markets. Verify RoHS3 compliance status with current suppliers before procurement. Ensure replacement components meet equivalent electrical specifications for legacy system maintenance.

Selection Notes

Select this component only for retrofitting existing designs where the original FB43-422 was specified. Do not use for new product development due to its obsolete status. Confirm that the 5.461 mm inner diameter accommodates the target cable bundle size. Evaluate alternative modern ferrite materials if frequency response requirements have changed since the original design phase.

Part Context

The FB43-422-RC belongs to the Bourns FB series of ferrite cable cores. This series is widely recognized for providing reliable electromagnetic interference suppression in various electronic assemblies. The specific model utilizes Type 43 material, which offers distinct permeability characteristics compared to other common ferrite compounds like Type 31 or 61.

Replacement Considerations

Official substitutes are not explicitly listed in public documentation. Consider generic Type 43 material cores with matching physical dimensions (approx. 5.5 mm ID x 12 mm length) from other manufacturers. Verify that any replacement maintains the same frequency performance profile above 200 MHz.
