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 PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a small form factor is critical for space-constrained designs. Choose the 18QHTF21-114.870-PD if the application demands a stable 114.87 MHz reference clock with low power consumption. Consider the LVCMOS output level compatibility with downstream logic gates to ensure signal integrity without additional buffering requirements.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan producing precision oscillators. This series typically offers various frequencies within a standardized small outline package format suitable for modern surface-mount technology applications.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts and voltages but different frequencies, such as 18QHTF21-115.314-OE. Verify that any replacement maintains the same LVCMOS logic family and physical 2.0x1.6mm package constraints to ensure board compatibility.
