Crystals Procurement Notes

Verify the specific suffix 'DD38' against the manufacturer's latest datasheet to confirm exact dimensional tolerances and soldering profile requirements. Ensure compatibility with standard reflow soldering processes for 4-SMD packages. Cross-reference part numbers carefully as minor suffix variations may indicate different temperature ranges or packaging options.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required with moderate stability needs. The 19 pF load capacitance must match the circuit design specifications. Consider the 40 Ohm ESR for driver circuit compatibility. Evaluate space constraints given the small footprint compared to through-hole alternatives.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and package sizes. The DD38 suffix typically denotes specific physical dimensions and pin configuration within this product line, distinguishing it from other variants like DB48 or CA17.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with identical 19 pF load capacitance and similar ESR values. Verify that alternative parts support the same operating temperature range and package dimensions to ensure mechanical fit.
