Crystals Procurement Notes

Verify the specific lot code and manufacturing date against project requirements before procurement. Ensure that the supply chain source provides authentic Suntsu Electronics products to avoid counterfeit components. Confirm that the 4-SMD package dimensions match the PCB footprint design exactly. Check for any special handling instructions regarding electrostatic discharge protection during storage and installation.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with high stability. The ±20 ppm stability rating suits applications sensitive to clock drift. Consider the 21 pF load capacitance compatibility with the host circuit's oscillator configuration. Evaluate the 60 Ohm ESR against the oscillator circuit's drive level limitations to ensure reliable startup and operation.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series typically includes various frequency options and package types designed for compact electronic designs. The DD38 suffix indicates specific physical and electrical characteristics within this product line, distinguishing it from other variants like the CB27 or DC17 series.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 21 pF load capacitance, and 4-SMD no-lead package. Verify that alternative parts meet or exceed the ±20 ppm stability and 60 Ohm ESR specifications. Ensure the replacement component supports fundamental mode operation and fits the same thermal and mechanical constraints.
