Procurement Notes

Verify the complete part number against official QST documentation to ensure correct suffix alignment. Confirm that the specific variant matches the required load capacitance and frequency tolerance for the target circuit design. Cross-reference package dimensions and thermal specifications with system constraints prior to integration.

Selection Notes

Select this component when a 32 MHz reference signal is required in space-constrained designs. Ensure the application environment remains within the -20°C to +70°C operational limits. Verify that the system impedance matches the 8 pF load capacitance requirement to maintain accurate frequency output without external tuning adjustments.

Part Context

This model belongs to the QT252S series of surface-mount crystals from QST. The series offers standardized footprints suitable for high-volume manufacturing processes. Components in this family provide consistent electrical performance profiles tailored for general-purpose timing applications in portable and industrial devices.

Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 4-SMD package, and 8 pF load capacitance. Verify equivalent ESR values and temperature stability ratings to ensure functional parity in existing circuit layouts without redesign requirements.
