• Communication interface synchronization

Procurement Notes

Verify the specific ordering suffix against official QST documentation to confirm exact tolerance and packaging specifications. Ensure the procurement channel provides valid traceability for RoHS compliance status. Cross-reference the part number with current manufacturer datasheets to validate availability and technical parameters before finalizing purchase orders.

Selection Notes

Select this component when a 5 MHz surface-mount crystal with 12 pF load capacitance is required. The ±30 ppm tolerance suits applications needing moderate precision. Confirm that the HC49 SMD package dimensions fit the target PCB layout constraints. Evaluate thermal stability requirements against the ±50 ppm specification.

Part Context

This part belongs to the QST QT49S series of surface-mount crystals. The series offers various frequencies and tolerance options within the HC49 SMD package. The QT49S-5.000MAGE-T specifically denotes the 5 MHz variant with defined electrical characteristics for general-purpose timing applications.

Replacement Considerations

Direct substitutes must match the 5 MHz frequency, 12 pF load capacitance, and HC49 SMD package. Verify equivalent frequency tolerance and stability ratings from alternative manufacturers. Ensure pinout compatibility and mounting orientation align with existing board designs.
