Oscillators Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 1.8V supply requirement aligns with your system's voltage rails. Check for any recent updates to the RoHS compliance status or lead-free certification before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The 4-SMD no-lead package offers space-saving advantages for dense PCB layouts. Ensure the 3.136 MHz frequency meets the exact timing requirements of the target application, as frequency customization may require different part numbers within the series.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz frequency control products. The series typically features small form factors and low power consumption profiles. Mercury Electronics has a long history in Taiwan's quartz industry, providing reliable timing solutions for various electronic sectors.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinouts but different frequencies, such as 18QHTF21-4.068-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application.
