Crystals Procurement Notes

Verify the specific suffix 'CAT' against official CTS documentation to confirm exact packaging or material variations. Ensure the selected variant matches the required load capacitance and tolerance for the target circuit design. Cross-reference the part number with current manufacturer availability status prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 20.48 MHz reference signal is required with ±10 ppm accuracy. The 10 pF load capacitance must match the oscillator circuit requirements. Consider the 4-SMD footprint constraints and the -20°C to +70°C operating range during PCB layout and environmental assessment phases.

Crystals Part Context

This part belongs to the CTS 402 Series, which comprises sub-miniature surface mount crystals. The series typically supports frequencies from 16 MHz to 96 MHz in a standardized 2.0 x 1.6 mm package. The 402F20411CAT represents a specific frequency configuration within this family, sharing common physical dimensions and mounting characteristics with other series members.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 402F20411CAR, 402F20411CKR, and 402F20411CJR. These alternatives share identical electrical parameters and mechanical footprint. Verify that any replacement maintains the same frequency tolerance and load capacitance specifications.
