Procurement Notes
Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct frequency and package specifications. Confirm that the -OE suffix aligns with your specific ordering requirements as defined in the manufacturer's datasheet. Cross-reference the RoHS status and lead-free compliance if required by your assembly process. Ensure the supplier provides valid traceability documents matching the original manufacturer's batch codes.
Selection Notes
Select this component when a 1.8V supply voltage and LVCMOS output are required for low-power digital applications. The 2.0x1.6mm package size is suitable for space-constrained designs. Verify that the 12.92 MHz frequency meets the system timing requirements. Consider the Enable/Disable feature if dynamic power control is necessary for the application environment.
Part Context
This oscillator belongs to the Mercury Electronics SMD XO series, which includes various frequencies and packages. The 18QHTF21 series typically offers standard performance levels for general electronic applications. Mercury Electronics has a long history in quartz crystal manufacturing, providing frequency control products including oscillators and filters.
Replacement Considerations
Check for direct substitutes from Mercury Electronics with identical pinout and electrical characteristics. Other manufacturers may offer compatible LVCMOS oscillators in similar packages, but verify frequency tolerance and supply voltage compatibility carefully.
