Crystals Procurement Notes

Verify the specific suffix 'XIAT' against the manufacturer's current datasheet to confirm packaging configuration and availability status. Ensure the required load capacitance matches the target oscillator circuit design. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±10 ppm stability is required. The 10 pF load capacitance must align with the host oscillator's specified load requirements. Consider the -20°C to +70°C temperature range suitability for the intended application environment before finalizing the design.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series is characterized by small form factors suitable for space-constrained electronics. The 402F2001XIAT specifically utilizes a 4-pin SMD footprint, distinguishing it from larger through-hole or different SMD variants within the broader frequency control portfolio.

Crystals Replacement Considerations

Direct substitutes include the 402F2001XILT and 402F2001XIJR, which share identical electrical specifications but may differ in reel packaging or lead finish. Verify package compatibility and soldering profile requirements when cross-referencing these alternatives.
