Procurement Notes
Verify the specific suffix 'B' against official QST documentation to confirm exact tolerance and pinout specifications. Ensure the 4-SMD footprint matches the target PCB design. Confirm active status and RoHS compliance through authorized distributors before ordering.
Selection Notes
Select this model when a 18.432 MHz CMOS clock source is required in a compact surface-mount form factor. Consider the 3.3V operating voltage and industrial temperature range suitability for the application environment. Verify that the enable/disable feature aligns with system power sequencing requirements.
Part Context
This component belongs to the QTM750 series of surface-mount oscillators from QST. The series offers various frequencies and packages, with this specific part providing a standard CMOS output in a 7x5mm footprint. It serves as a timing reference solution for modern electronic designs requiring reliable clock signals.
Replacement Considerations
Direct substitutes include other QTM750 variants with identical frequency and package, such as QTM750-18.432MBE-T or QTM750-18.432MBB-T, provided electrical parameters match. Cross-manufacturer replacements require verification of pinout, voltage, and output waveform compatibility.
