Crystals Procurement Notes

Verify the specific frequency tolerance requirement against available datasheet variants, as documentation indicates both ±15 ppm and ±25 ppm specifications for this part number. Confirm package dimensions match PCB footprint requirements. Ensure supply chain availability due to reported stock constraints. Request official RoHS compliance documentation prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 19.6608 MHz reference is required in a minimal footprint SMD package. Consider the 8 pF load capacitance compatibility with the target oscillator circuit design. Evaluate the ESR value against driver capability requirements. Compare thermal performance needs against the -40°C to +85°C operational range.

Crystals Part Context

This model belongs to the SXT324 series of tuning fork crystals produced by Suntsu Electronics. The series offers various frequency options in standardized surface-mount packages. The EC48 suffix typically denotes specific package and parameter configurations within this product line, distinguishing it from other variants like EA38 or BB48 which may differ in capacitance or tolerance.

Crystals Replacement Considerations

Direct substitutes include SXT32422BB48-19.6608M, though it features 22 pF load capacitance and different tolerance characteristics. Verify electrical compatibility before substitution. Other generic 19.6608 MHz crystals in similar SMD packages may serve as alternatives if pinout and electrical parameters align.
