Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in listings associated with both QST and TXC Corporation. Confirm the specific datasheet version and electrical parameters match your design requirements before ordering. Ensure the supplier provides original documentation to validate the component's authenticity and performance specifications.

Selection Notes

Select this component when a 25 MHz reference is required in a minimal 2.0x1.6 mm footprint. The ±20 ppm stability suits general-purpose digital logic and communication interfaces. Consider the -20°C to +70°C operating range against your environmental constraints. The 6 pF load capacitance must align with the oscillator circuit design.

Part Context

This crystal belongs to the QT216G series, characterized by small surface-mount dimensions. It serves as a fundamental timing element for synchronous digital systems. The glass seal technology differentiates it from ceramic-packaged alternatives, offering specific reliability characteristics for mass-produced consumer devices.

Replacement Considerations

QT216G-25.000MDDQ-T offers similar 25 MHz operation but may differ in load capacitance or package tolerance. Verify pin compatibility and electrical specs before substitution.
