Resonators Procurement Notes

Verify the specific suffix 'Z' indicates the extended temperature range and built-in capacitor configuration as documented. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required frequency tolerance and load capacitance specifications for the target application circuit.

Resonators Selection Notes

Select this component when a compact solution with integrated capacitors is required to minimize board space. Consider the extended temperature rating if the operational environment exceeds standard commercial limits. Evaluate the 7 MHz frequency against system clock requirements and ensure compatibility with the host microcontroller or logic family input impedance characteristics.

Resonators Part Context

This part belongs to the CERALOCK CSTCR series, designed as a cost-effective alternative to crystal oscillators. It offers comparable performance to discrete crystal circuits but with reduced assembly complexity due to internal capacitors. The series is widely used in general-purpose digital circuits where moderate frequency accuracy suffices.

Resonators Replacement Considerations

Direct substitutes include other Murata CSTCR variants with matching 7 MHz frequency and 33 pF internal capacitance. Verify that alternative parts maintain the same physical footprint and electrical parameters to ensure mechanical and functional compatibility without redesign.
