Crystals Procurement Notes

Verify the specific suffix EC16 against official Suntsu datasheets to confirm package dimensions and soldering profiles. Ensure the required frequency tolerance of ±15 ppm aligns with system timing requirements. Cross-reference the 18pF load capacitance with the host circuit design to prevent frequency deviation. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 18.432 MHz reference is required for UART or SPI interfaces. The 70 Ohm ESR must match the oscillator circuit's drive level specifications. Consider the 4-SMD footprint constraints during PCB layout. Verify that the operating temperature range meets the application environment. Compare against alternative crystals if tighter stability or different package sizes are needed.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability options in a standardized small outline package. The EC16 suffix typically denotes specific mechanical and electrical characteristics within this family, distinguishing it from other variants like EB17 or DC16 which may have different tolerances or temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 18pF load capacitance and similar ESR values. Check pinout compatibility for the 4-SMD no-lead package. Verify that replacement parts meet the same ±15 ppm stability requirement. Ensure the substitute manufacturer supports the required volume and quality standards.
