Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a 10.026 MHz clock source is required with minimal power consumption. The LVCMOS output ensures compatibility with standard logic families. Consider the small form factor for space-constrained designs. Verify that the operating temperature range meets your environmental specifications. Compare against other Mercury Electronics models if different frequencies or voltages are needed.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes. The 'PD' suffix indicates the power-down feature. Similar parts include the 18QHTF21-8.000-PD and 18QHTF21-44.530-PD, which share the same package and voltage characteristics but differ in frequency.

Replacement Considerations

Direct substitutes may include other 10.026 MHz XO components with identical 1.8V LVCMOS outputs and 2.0x1.6mm packages. Cross-reference with Mercury Electronics' full catalog for equivalent parts. Ensure pinout compatibility and electrical specifications match exactly before substitution.
