Procurement Notes

Verify the current product status before procurement planning. Public documentation indicates this specific part number may be classified as End-of-Life or discontinued. Confirm availability through authorized distributors and assess lifecycle status to ensure long-term supply chain stability for production requirements.

Selection Notes

Select this component only if the design specifically requires a SAW filter centered at 1.227 GHz with a 0.95 dB bandwidth. Evaluate the 6-SMD package dimensions against board space constraints. Consider that the part may be obsolete; verify alternative sourcing options or newer generation replacements if long-term manufacturing support is required.

Part Context

The SF2208E belongs to the broader category of Murata SAW filters, which are widely used in RF applications. These devices leverage acoustic wave propagation on piezoelectric substrates to achieve sharp frequency selectivity. The SF2208E specifically targets the 1.227 GHz band, distinguishing it from other frequencies within the manufacturer's extensive portfolio.

Replacement Considerations

Public sources indicate the SF2208E is marked as EOL (End-of-Life). No specific public substitute part numbers are confirmed in the provided data. Engineers should consult Murata directly for valid cross-reference recommendations or next-generation equivalents.
