Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure correct pinout and electrical characteristics. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any recent revisions to the 18QHTF21 series specifications before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a specific 75.0012 MHz frequency. Consider the small 2.0x1.6mm footprint for space-constrained PCB layouts. Ensure the LVCMOS output level matches the input requirements of the connected load circuitry.
Part Context
This part belongs to the Mercury Electronics SMD oscillator series, which focuses on miniaturized frequency control solutions. The 18QHTF21 series is characterized by its small form factor and low power consumption, catering to modern portable and high-density electronic devices requiring reliable clock sources.
Replacement Considerations
Direct substitutes must match the 75.0012 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and thermal specifications before swapping manufacturers.
