Procurement Notes

Verify the specific suffix MEIV-T against official QST documentation to confirm the exact temperature range and tolerance specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference the manufacturer datasheet for handling instructions and storage conditions to maintain component integrity during assembly.

Selection Notes

Select this component when a 16 MHz fundamental frequency is required with ±10 ppm stability over a -30°C to +85°C range. The 8 pF load capacitance must match the oscillator circuit design. Consider the SMD form factor for automated assembly processes and space-constrained board layouts compared to through-hole alternatives.

Part Context

This part belongs to the QT325G series of quartz crystals from QST. The series offers various frequency and tolerance options in a standardized surface-mount package. The QT325G designation indicates a specific footprint and electrical characteristic set common across the product line, ensuring interchangeability within defined parameters.

Replacement Considerations

Consult QST technical support or authorized distributors for verified substitute part numbers. Generic replacements may not match the specific -30°C to +85°C temperature range or ±10 ppm stability requirements. Validate any alternative against the original schematic load capacitance and drive level specifications.
