Oscillators Procurement Notes

Verify the specific supply voltage requirement against the target application circuit before procurement. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Ensure the 4-SMD no-lead package footprint matches the PCB design guidelines to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a fixed frequency of 23.79021 MHz is required with low power consumption capabilities. The enable/disable feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the operating temperature range and load capacitance requirements to ensure system stability under varying environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies and voltage options, all sharing the same small form factor. Mercury Electronics has been a pioneer in the Taiwan crystal industry since 1973, providing reliable timing solutions for global markets.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts but different frequencies, such as 18QHTF21-25.000-OE, if frequency adjustment is permissible. Cross-brand replacements must match the 4-SMD no-lead package, LVCMOS output, and 23.79021 MHz frequency precisely to maintain electrical compatibility.
