Crystals Procurement Notes

Verify the specific load capacitance requirement matches your circuit design, as this unit specifies 8pF. Confirm that the 60 Ohm ESR aligns with your oscillator circuit's drive level limitations to prevent over-driving or failure to start. Ensure the 2.5x2.0mm package dimensions fit within your board's mechanical constraints and solder mask definitions.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 40MHz output is suitable for general-purpose digital systems. Consider the 8pF load capacitance carefully; mismatched load capacitors in the host circuit will cause frequency deviation. For higher temperature stability or different frequencies, consult the XT224 series variants.

Crystals Part Context

This part belongs to the YIC XT224 series of surface-mount crystals. The series offers various frequencies and package sizes, with the XT224 specifically denoting the 2.5x2.0mm footprint. It serves as a cost-effective timing solution for consumer electronics and industrial control boards where space is limited but basic timing accuracy is sufficient.

Crystals Replacement Considerations

Direct substitutes include other 40MHz crystals in 2.5x2.0mm packages with 8pF load capacitance and similar ESR values. Cross-reference with manufacturers offering XT224-compatible footprints. Verify that any replacement maintains the same fundamental frequency mode and thermal characteristics.
