Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 2.5V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-frequency 2.1 MHz reference signal is required with LVCMOS compatibility. Consider the enable pin if dynamic power saving is necessary. Compare against other models in the 25QHTF21 series for alternative frequencies or voltage levels if the standard 2.5V operation does not suit the target application environment.

Oscillators Part Context

This part belongs to the 25QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a consistent 4-SMD no-lead form factor. These components are designed for general electronic applications where stable clock signals are essential, leveraging Mercury's expertise in quartz crystal manufacturing established since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 25QHTF21 series variants with identical pinout and electrical characteristics but different frequencies, such as 25QHTF21-17.200-OE or 25QHTF21-46.000-OE, provided the frequency difference is acceptable for the design.
