Resonators Procurement Notes

Verify the obsolete lifecycle status before design finalization. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and reflow profiles. Validate electrical parameters against current application requirements due to potential supply chain variations.

Resonators Selection Notes

Select this component for applications requiring precise 315.050 MHz generation. Consider the narrow frequency tolerance for stable carrier signals. Evaluate thermal performance within the specified -40°C to +105°C range. Assess space constraints regarding the surface-mount ceramic package dimensions.

Resonators Part Context

This part belongs to Murata's SAW resonator family, specifically designed for radio frequency applications. It shares architectural similarities with other single-port resonators but is distinct in its specific frequency and tolerance specifications. The ceramic package provides environmental protection compared to alternative mounting styles.

Resonators Replacement Considerations

Direct substitutes include the RO3073A and RO3073E-11. Verify frequency accuracy and package compatibility when cross-referencing these alternatives. Ensure that the substitute parts meet the same thermal and electrical specifications required by the original design.
