Crystals Procurement Notes

Verify the specific suffix 'AA48' against official Suntsu documentation to confirm package dimensions and soldering profile requirements. Ensure the load capacitance specification matches the target circuit design to maintain frequency accuracy. 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 commercial-grade applications. Consider the ±50 ppm stability limit against system timing requirements. Evaluate the 4-SMD footprint compatibility with existing PCB layouts and manufacturing capabilities before finalizing the design choice.

Crystals Part Context

This part belongs to the SXT21411 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and stability grades. The AA48 suffix typically denotes specific physical dimensions and terminal configurations distinct from other variants in the same family.

Crystals Replacement Considerations

Direct substitutes include SXT21411CC48-18.432M, which offers improved ±25 ppm stability but may require verification of pinout and thermal characteristics. Cross-reference mechanical drawings to ensure footprint compatibility before substitution.
