Procurement Notes

Verify that the ordering suffix matches the required frequency tolerance and temperature range specifications. Confirm package dimensions and lead-free status align with assembly requirements. Ensure compatibility with reflow soldering profiles specified in the official datasheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate electrical parameters against system design constraints before procurement.

Selection Notes

Select this component when a 48 MHz clock source with ±30 ppm stability is required in a minimal footprint. Consider the 10 pF load capacitance for matching oscillator circuit requirements. Evaluate thermal performance within the -40°C to +85°C range for environmental suitability. Compare against alternative frequencies if system flexibility allows. Ensure SMD mounting capabilities match manufacturing processes.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST, characterized by small form factors and high reliability. The series supports various frequencies and tolerances, catering to diverse timing needs. The 48 MHz variant specifically addresses common clocking requirements in modern digital systems. It complements other components in timing-critical assemblies where size and stability are paramount.

Replacement Considerations

Direct substitutes include other 48 MHz crystals with identical ±30 ppm tolerance and 10 pF load capacitance in a 2.0x1.6mm SMD package. Verify equivalent frequency stability and operating temperature ranges. Check for compatible drive levels and impedance characteristics. Ensure mechanical dimensions match existing PCB footprints. Consult manufacturer cross-reference lists for validated alternatives.
