Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and pinout configurations. Ensure the selected variant matches the required operating temperature range and load capacitance specifications for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage 1.8V supply is available and a minimal footprint is required. Consider the LVCMOS output swing levels relative to the receiving input thresholds. Evaluate the need for the enable/disable feature against system power efficiency requirements and control signal availability.
Part Context
This part belongs to the Mercury 18QHTF series of miniature crystal oscillators. The series typically offers various frequency options within a standardized 2.0x1.6mm package. These components are engineered for applications demanding stable clock signals in space-constrained modern electronics.
Replacement Considerations
Cross-reference with other 18QHTF series variants from Mercury Electronics for different frequencies. Verify pin-to-pin compatibility with alternative manufacturers offering similar 4-SMD no-lead oscillators before substitution.
