Procurement Notes

Verify the specific suffix 'MEEQ' against official QST documentation to confirm package type and availability status. Ensure that the 14.31818 MHz frequency and ±10 ppm tolerance align with system requirements. Cross-reference the 4-SMD No Lead footprint with PCB design files to prevent mechanical mismatches during procurement.

Selection Notes

Select this component when a precise 14.31818 MHz reference is required for communication interfaces. Consider the ±10 ppm tolerance for stability needs and the 40 Ohm ESR for circuit drive level compatibility. Evaluate the 5.0x3.2 mm package size against spatial constraints in the target application design.

Part Context

This part belongs to the QT532S series of quartz crystals from QST. The series supports various frequencies for microcontroller and clock circuit applications. While some related oscillators like the QTM532L have been discontinued, this specific crystal model remains available for standard timing needs.

Replacement Considerations

Direct substitutes may include other 14.31818 MHz crystals with matching 10 pF load capacitance and similar ESR values. Verify package dimensions and pin configuration compatibility before swapping components.
