Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no lead package dimensions fit within the available PCB footprint constraints for the intended assembly process.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable pin for power control. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 4-SMD form factor for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequency options within a standardized small outline package. The manufacturer leverages decades of experience in quartz crystal production to provide reliable frequency control solutions for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Direct substitutes must match the 27.0016 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent enable/disable pin configurations and electrical characteristics from other manufacturers offering similar SMD oscillator portfolios.
