Crystals Procurement Notes

Verify the specific suffix requirements against the official CTS datasheet to ensure compatibility with your circuit's load capacitance and tolerance needs. Confirm that the 4-SMD package dimensions align with your PCB footprint constraints. Check current availability status as supply levels may fluctuate. Ensure compliance with RoHS3 standards if required by your manufacturing process. Validate thermal performance within the specified -20°C to +70°C range for your intended application environment.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency crystal is required with a 9 pF load capacitance. Consider the ±15 ppm stability requirement against your system's timing accuracy needs. Evaluate the 60 Ohm ESR to ensure it matches your oscillator circuit's drive level capabilities. Compare the physical size of the 2.00 x 1.60 mm package against available board space. Assess the operating temperature range to confirm suitability for your environmental conditions.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series provides various frequency options and package sizes for general-purpose frequency control applications. The 402F500XXCJT specifically addresses the need for a 50 MHz reference in compact designs. It shares common characteristics with other parts in the series, such as similar packaging and operational modes, but differs in specific electrical parameters like frequency and load capacitance.

Crystals Replacement Considerations

Direct substitutes include 402F500XXCLR and 402F500XXCJR. Verify that these alternatives match the exact 50 MHz frequency, 9 pF load capacitance, and 60 Ohm ESR specifications. Ensure the replacement packages are compatible with your existing PCB layout. Confirm that the replacement parts meet the same ±15 ppm stability and temperature range requirements.
