Crystals Procurement Notes

This component is officially discontinued and no longer manufactured by Citizen Finedevice. Procurement should focus on verified replacement parts rather than original stock. Verify that substitute components match the required frequency, load capacitance, and package dimensions. Ensure compatibility with existing circuit designs before transitioning to alternative suppliers or models.

Crystals Selection Notes

Select replacement crystals based on identical electrical parameters including frequency, tolerance, and load capacitance. Verify package footprint compatibility to ensure seamless integration into existing PCB layouts. Consider operating temperature ranges and stability requirements specific to the application environment. Cross-reference manufacturer datasheets to confirm equivalent performance characteristics.
