Crystals Procurement Notes

Verify the specific suffix CA17 against official datasheets to confirm load capacitance and ESR values match system requirements. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm RoHS compliance status if required by project regulations. Cross-reference part numbers to avoid confusion with similar variants in the SXT324 series.

Crystals Selection Notes

Select this component when a 18.432 MHz frequency is required with ±25ppm stability. The 9pF load capacitance must align with the oscillator circuit design. The 70 Ohm ESR should be compatible with the driving capability of the host microcontroller or clock generator. Consider the 3.20mm x 2.50mm footprint for PCB layout constraints.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and stability grades. The CA17 suffix typically denotes specific electrical characteristics within this family, distinguishing it from other variants like CC07 or BA16 which may have different stability or temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other SXT3249CA17-18.432M units from authorized distributors. Alternative manufacturers producing 18.432 MHz crystals in 3225 packages with 9pF load capacitance and similar ESR may be considered after verifying electrical parameters and mechanical fit.
