Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The integrated power-down feature makes it suitable for applications where battery life is critical. Consider the small 4-SMD package size for space-constrained designs. Ensure the 19.1328 MHz frequency meets the clocking needs of the target microcontroller or processor.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal components. The manufacturer has decades of experience in Taiwan's crystal industry. This series typically offers standard oscillators with various frequencies and supply voltages, catering to general-purpose timing applications in modern electronics.

Oscillators Replacement Considerations

Direct substitutes within the same series include other frequencies such as 18QHTF21-51.200-PD or 18QHTF21-6.000-PD, provided the frequency difference is acceptable. Cross-manufacturer replacements must match the 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions.
