Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low voltage operation. The 2.0x1.6mm package size suits space-constrained designs. Consider the LVCMOS output type for direct interfacing with standard digital logic families without additional buffering components.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead package. The series supports multiple supply voltages and output types, allowing designers to choose based on specific system power and logic requirements while maintaining consistent physical dimensions.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical package dimensions but different frequencies, such as 18QHTF21-25.000-PD or 18QHTF21-27.000-PD, provided the system timing allows for frequency adjustment. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators if pin-out compatibility is verified.
