Crystals Procurement Notes

Verify that the ordering suffix matches the required frequency tolerance and load capacitance specifications. Confirm the package type corresponds to the 4-pin SMD ceramic variant. Ensure the component meets RoHS and lead-free processing requirements for your assembly line. Cross-reference the part number against official ILSI documentation to confirm availability and exact electrical parameters before procurement.

Crystals Selection Notes

Select this component when a low-cost, ultra-miniature crystal is required for frequencies between 16 MHz and 23.999999 MHz. It is appropriate for designs needing ±30 ppm tolerance and 8 pF load capacitance. Consider the 80 Ohm maximum ESR limit for oscillator circuit compatibility. This part is suitable for applications requiring standard AT-cut performance in a compact SMD form factor.

Crystals Part Context

This part belongs to the ILSI ILCX19 series, which offers various frequency options in a consistent 2.0mm x 1.6mm package. The series provides multiple tolerance grades, indicated by suffixes such as F for ±30 ppm. Other variants in the series may differ in frequency, tolerance, or load capacitance while maintaining the same physical dimensions and general application scope.

Crystals Replacement Considerations

Direct substitutes include other ILCX19 series parts with matching 20 MHz frequency and ±30 ppm tolerance. Verify that replacement crystals have compatible 8 pF load capacitance and similar ESR limits. Ensure the alternative maintains the 4-pin SMD ceramic package for board layout compatibility.
