Crystals Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and temperature range, as these parameters vary across the SXT214 series. Ensure the required load capacitance matches the host circuit design. Cross-reference the datasheet for the specific part number to confirm active status and availability before procurement.

Crystals Selection Notes

Select this component when space constraints require a 2.0mm x 1.6mm footprint. The 60 Ohm ESR is appropriate for 50MHz fundamental oscillation circuits. Verify that the ±20ppm tolerance meets the system's jitter requirements. Consider the operating temperature range if the application involves extreme environmental conditions.

Crystals Part Context

This part belongs to the SXT214 series of ceramic SMD crystals from Suntsu Electronics. The series is characterized by its small form factor and suitability for portable electronics. The model number indicates a 50MHz frequency with specific electrical characteristics defined by the manufacturer's coding system.

Crystals Replacement Considerations

Direct substitutes must match the 2.0x1.6mm package, 50MHz frequency, 20pF load capacitance, and ≤60 Ohm ESR. Verify pin compatibility and thermal performance. Generic replacements may differ in aging rate or drive level sensitivity.
