Resonators Procurement Notes

Verify the specific suffix codes against the official Murata datasheet to ensure correct tolerance and packaging specifications. Confirm that the required operating temperature range aligns with the component's rated limits. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed with integrated capacitance. Ensure the application can accommodate the inherent higher Q-factor variation compared to discrete crystals. Verify that the PCB footprint matches the specified 3.2mm x 1.3mm dimensions and that the load capacitance requirements match the 33 pF internal value.

Resonators Part Context

This part belongs to the CSTNE_G_Z series within the broader CERALOCK family. It represents a standard small-cap chip type ceramic resonator. The series is engineered for general-purpose timing applications where moderate accuracy is sufficient. It serves as a direct replacement for older discontinued series like CSTCE in many designs.

Resonators Replacement Considerations

The CSTCE12M5G55-R0 is listed as a discontinued substitute option by distributors. However, verify pin compatibility and electrical parameter differences carefully. No other official direct substitutes are confirmed in public documentation.
