Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and package configuration. Confirm that the required operating temperature range aligns with the component specifications provided in the datasheet. Ensure that the supply voltage requirements match the system design constraints before procurement.
Selection Notes
Select this component when a low-voltage, low-power oscillator is required for portable applications. The 1.8V supply and standby feature make it suitable for battery-operated devices. Consider the 4-SMD package size for PCB layout constraints. Verify that the LVCMOS output level is compatible with the receiving logic inputs of the target circuit.
Part Context
This part belongs to the 18QHTF series of low-power oscillators from Mercury Electronics. The series offers various frequencies and includes standby functionality. These components are designed for applications where power efficiency and small form factor are critical priorities.
Replacement Considerations
Direct substitutes include other parts from the same series with matching frequencies, such as 18QHTF21-8.500-OE, provided the electrical characteristics and package dimensions are compatible. Always verify pinout and voltage levels before substitution.
