Crystals Procurement Notes

Verify the specific suffix FD48 corresponds to the 4-SOJ 5.50mm pitch package configuration. Confirm that the 18pF load capacitance matches the target circuit design requirements. Ensure the ±10ppm stability rating meets the system's frequency tolerance specifications before procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required with tight ±10 ppm stability. The 4-SOJ package suits automated surface-mount assembly processes. Verify compatibility with the host circuit's load capacitance and ESR constraints to ensure optimal oscillator performance.

Crystals Part Context

This part belongs to the Suntsu Electronics SXT8 series of plastic surface-mount crystals. It shares the 20 MHz frequency point with other variants like SXT83418FE16-20.000M but differs in package type. The series offers various pitch options to accommodate different PCB layout densities.

Crystals Replacement Considerations

Direct substitutes include SXT83418FE16-20.000M if the package footprint allows. Cross-reference with SXT83418CB48-24.000M only if frequency changes are acceptable. Verify pinout and mechanical dimensions match the existing board space.
