Procurement Notes

Verify the specific suffix 'MDIQ' against official QST documentation to confirm the exact load capacitance and stability ratings. Ensure the ordering quantity matches the manufacturer's standard tape and reel specifications. Cross-reference the date code and lot number to guarantee compliance with current RoHS directives and material declarations before finalizing procurement orders.

Selection Notes

Select this component when a 38.4 MHz reference signal is required with tight ±20 ppm stability constraints. The 10 pF load capacitance must align with the host circuit's design parameters. Consider the 2.0x1.6 mm package dimensions for PCB layout compatibility. Evaluate thermal performance requirements against the -40°C to +85°C operational range to ensure long-term reliability under varying environmental conditions.

Part Context

This part belongs to the QT216G series of surface-mount crystals from QST. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The QT216G variant specifically targets applications requiring small form factors without compromising frequency precision or thermal robustness compared to larger through-hole alternatives.

Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with identical 2.0x1.6 mm dimensions, 10 pF load capacitance, and ±20 ppm stability. Verify equivalent ESR values and drive level specifications to maintain circuit oscillation integrity. Check pinout compatibility if the replacement uses a different lead configuration.
