Crystals Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the design specifications before procurement. Confirm that the selected variant matches the required ±15ppm stability and 12pF load capacitance. Ensure the PCB footprint accommodates the 4-SMD no-lead package dimensions. Check for any RoHS compliance documentation if environmental regulations apply to the final assembly process.

Crystals Selection Notes

Select this component when a 50 MHz reference is required in a compact surface mount form factor. Consider the ±15ppm stability limit for timing accuracy requirements. Evaluate the 60 Ohm ESR against the oscillator circuit drive level capabilities. Compare the 4-SMD package size against available board space constraints relative to other crystal options.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequency codes and package options for SMD applications. The 402F500XXCLT specifically targets 50 MHz applications requiring moderate stability in a small outline package format suitable for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes include variants such as 402F50011CAT or 402F50033CLR, provided they match the 50 MHz frequency, 12pF load capacitance, and 4-SMD package dimensions. Verify that alternative parts meet the same ±15ppm stability and 60 Ohm ESR specifications to ensure circuit compatibility.
