Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current supply status and lifecycle stage before integration into new designs. Sourcing should focus on verified distributors offering genuine parts to ensure authenticity and compliance with RoHS standards.

Selection Notes

Select this part only if legacy compatibility with 450 kHz systems is required. Consider the leaded package constraints for modern automated assembly lines. Evaluate alternative active filters or newer ceramic components if space and throughput efficiency are critical priorities for the target application.

Part Context

Part of the Murata CERAFIL series, which specializes in ceramic discriminators and filters for communication hardware. This specific model represents a passive filtering solution utilizing piezoelectric ceramic materials to achieve precise frequency selection and noise rejection in analog signal paths.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements must be identified through independent engineering analysis or manufacturer obsolescence notices.
