Procurement Notes

Verify that the specific suffix 'XC7T' matches the required frequency tolerance and packaging configuration. Confirm RoHS compliance status if restricted substances are mandated by project specifications. Ensure the selected variant aligns with the thermal requirements of the final application environment.

Selection Notes

Select this component when high precision timing is required without the complexity of quartz crystals. The built-in capacitor feature reduces board space and component count. Consider the ±0.2% tolerance for applications sensitive to frequency drift. Verify compatibility with the target microcontroller's input impedance requirements.

Part Context

This part belongs to TDK's CCR series of ceramic resonators, which are designed as cost-effective alternatives to quartz crystals. The series offers various frequency options and package sizes to accommodate different embedded system needs while maintaining reliable performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes include other TDK ceramic resonators with identical 16.93 MHz frequency and 9 pF load capacitance. Cross-reference pinout and footprint dimensions to ensure mechanical compatibility during replacement or redesign phases.
