Crystals Procurement Notes

Verify the specific load capacitance requirement of 9pF against the target circuit design, as this differs from other variants in the series. Confirm that the ±10ppm stability meets the system's jitter and phase noise specifications. Ensure the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the final application. Check current availability status as supply chain constraints may affect lead times.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with a 9pF load capacitance. Compare against the 402F50011CAT variant if a 10pF load capacitance is preferred for the specific oscillator circuit. Consider the 402F50011CJR or CKR alternatives only if their respective packaging or minor parameter variations better suit the manufacturing process. Verify that the 60 Ohm ESR is compatible with the driving circuit's power requirements.

Crystals Part Context

This part belongs to the CTS 402 Series of MHz crystals, which are characterized by high reliability and low cost. The series offers various frequency codes and load capacitance options to accommodate different oscillator designs. The 402F50011CJT specifically addresses the need for precise 50 MHz timing in consumer and industrial electronics using standard surface-mount technology.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 402F50011CAT, 402F50011CJR, and 402F50011CKR. Note that these substitutes may have different load capacitances (e.g., 10pF for CAT) or packaging suffixes. Verify electrical compatibility before substitution.
