Resonators Procurement Notes

Verify the specific suffix 'Z' against official Murata documentation to confirm compliance requirements and material specifications. Ensure the ordering code matches the exact frequency and tolerance parameters required by the design. Cross-reference the datasheet revision date to confirm current manufacturing status and availability constraints.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed for moderate precision applications. The integrated 39 pF load capacitor eliminates external components, reducing board space. Verify that the 50 Ohm dynamic resistance aligns with the oscillator circuit's drive level requirements to prevent over-driving or failure to start.

Resonators Part Context

This part belongs to the CSTCR_G series of ceramic resonators manufactured by Murata Electronics. The series is characterized by its small footprint and built-in capacitor options, distinguishing it from standard two-lead ceramic resonators. It serves as a key solution for mass-produced consumer devices requiring reliable timing without the higher cost of crystal units.

Resonators Replacement Considerations

Direct substitutes must match the 6.4 MHz frequency, 39 pF load capacitance, and 4.5x2x1.15 mm package dimensions. Verify equivalent dynamic resistance and temperature stability ranges before substitution.
