Crystals Procurement Notes

Verify the specific suffix EC07 against official Suntsu documentation to confirm the exact temperature range and stability class. Ensure the required load capacitance matches the circuit design. Cross-reference the package dimensions with the mechanical drawing to confirm compatibility with PCB footprint constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz reference with ±15 ppm stability is required. The 0°C to +70°C operating range suits commercial environments. Consider the 100 Ohm ESR and 18 pF load capacitance for oscillator circuit tuning. Verify that the 4-SMD form factor fits the available board space compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability grades. The SXT21418EC07-27.000M specifically targets applications needing moderate stability in a small footprint. Other variants in the series may differ in temperature range or frequency tolerance.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 18 pF load capacitance and 4-SMD packages. Verify that replacement parts meet the ±15 ppm stability and 0°C to +70°C temperature requirements. Check ESR values to ensure oscillator startup reliability.
