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 RoHS compliance status if required by your manufacturing standards. Validate the manufacturer part number to avoid confusion with similar series variants.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is mandatory for the target application. Consider the small form factor suitable for space-constrained designs. Verify compatibility with LVCMOS interfaces used in the downstream digital logic. Evaluate the need for standby capability to manage power consumption during idle periods. Compare against other frequencies in the 18QHTF21 series if different clock speeds are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies including 8.0 MHz, 15.7 MHz, 48.7056 MHz, and 51.2 MHz. All units share the same 1.8V supply requirement and 4-SMD No Lead packaging style, ensuring mechanical consistency across different clock speeds within the product line.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts such as 18QHTF21-8.000-PD or 18QHTF21-15.700-PD if frequency differences are acceptable. Cross-brand replacements require matching the 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions precisely.
