Crystals Procurement Notes

Verify the complete part number including suffixes against official TXC documentation to ensure correct load capacitance and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference manufacturer datasheets for handling instructions and soldering profiles to maintain component integrity during assembly processes.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental mode crystal is required for designs demanding ±30 ppm stability over wide temperature variations. Ensure circuit design accommodates the specified 20 pF load capacitance to achieve accurate frequency output. Verify that the PCB layout supports the 4-SMD package dimensions and that drive levels remain within safe operational limits defined in the technical specifications.

Crystals Part Context

This model belongs to the 7M series of surface-mount crystals from TXC Corporation, designed for general-purpose timing applications. The series offers various frequency options within standardized packages to facilitate design-in flexibility. The 7M-19.2000MAHK-T specifically addresses common clocking needs in digital circuits where moderate stability and broad thermal performance are prioritized over ultra-high precision.

Crystals Replacement Considerations

Direct substitutes include other 19.2 MHz crystals with identical 20 pF load capacitance and ±30 ppm tolerance in the same 3.2x2.5mm package. Verify ESR compatibility and temperature range alignment before substitution. Alternative models from different manufacturers must match electrical parameters and physical footprint to ensure seamless integration without redesign.
