Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability data to ensure compatibility.

Selection Notes

Select this component when a low-profile 2.0x1.6 mm oscillator is required for space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power portable electronics. Consider the LVCMOS output compatibility with your downstream logic levels. Verify that the 12.886 MHz frequency meets your specific timing needs compared to standard frequencies like 12.0 MHz or 13.0 MHz.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which offers various frequency options in a standardized small outline package. The series is characterized by its low profile and support for power-down modes. Similar parts in the family include variants with different frequencies such as 12.0 MHz or 13.0 MHz, maintaining the same package and electrical interface specifications.

Replacement Considerations

Direct replacements must match the 12.886 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check equivalent models from other manufacturers ensuring identical pinout and electrical parameters. Verify that any substitute component supports the required standby function and meets the same temperature range specifications.
