Procurement Notes
Verify the specific ordering suffix against official QST documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference datasheets from authorized distributors to validate current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a 27 MHz reference signal is required for embedded processors or communication modules. Consider the ±20 ppm stability requirement relative to system timing accuracy needs. Evaluate the 12 pF load capacitance against the oscillator circuit design to ensure proper oscillation startup and sustained amplitude.
Part Context
This part belongs to the QT216G series of quartz crystals manufactured by QST. The series offers various frequency options and package configurations tailored for modern electronic devices. The MDIE suffix typically denotes specific terminal plating and packaging characteristics within the product line.
Replacement Considerations
Direct substitutes may include other 27 MHz SMD crystals with identical 2x1.6x0.6mm dimensions and 12 pF load capacitance. Verify equivalent frequency stability (±20 ppm) and temperature range (-40°C to +85°C). Check manufacturer-specific pinout and mounting requirements to ensure mechanical and electrical compatibility.
