Procurement Notes

Verify the complete part number including suffixes such as METV-T against official QST documentation to ensure correct packaging and specifications. Confirm that the supplier provides genuine components with traceable origin. Request datasheets matching the specific variant to validate electrical parameters like ESR and load capacitance before finalizing orders.

Selection Notes

Select this component when a precise 38.4 MHz timing source is required in small form factors. Ensure the application circuit supports the specified 8pF load capacitance to maintain accuracy. Consider the -30°C to 85°C operating range suitability for the intended environmental conditions. Verify board layout constraints align with the 4-SMD footprint dimensions.

Part Context

This part belongs to the QT216S series of quartz crystals from QST. The series offers various frequencies within a standardized 2.0x1.6mm package. The METV-T suffix indicates specific terminal configuration and tape-and-reel packaging. This model provides a balance between size, performance, and cost for mass-produced electronic devices requiring stable clock signals.

Replacement Considerations

Direct substitutes include other 38.4 MHz crystals in 4-SMD packages with similar electrical characteristics. Check compatibility regarding load capacitance and ESR values. Ensure replacement parts meet the same temperature stability requirements. Verify pinout and mechanical dimensions match the existing PCB footprint to avoid rework.
