Crystals Procurement Notes

Verify the specific suffix 'I' against official manufacturer documentation to confirm the exact temperature grade and material composition, as suffix variations often denote distinct environmental or reliability specifications within the same series. Cross-reference the 13pF load capacitance requirement with the target circuit design to ensure proper oscillator loading conditions are met before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12.688 MHz fundamental frequency is required with strict ±30 ppm tolerance limits. The 13pF load capacitance specification must align with the host oscillator circuit's internal capacitive requirements. Ensure the PCB layout accommodates the 6.00mm x 3.50mm footprint and that the application environment remains within the specified -40°C to +85°C operational range for guaranteed performance.

Crystals Part Context

This component belongs to the CTS 406 Series of surface-mount crystals, designed for general-purpose timing applications. The series offers various frequencies and packages, with the 406I variant specifically addressing industrial temperature requirements. It serves as a passive frequency-determining element in electronic circuits requiring stable clock signals without active oscillation capabilities.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in the provided source data. Verify compatibility with alternative crystals by matching the 12.688 MHz frequency, 13pF load capacitance, 60 Ohm ESR, and identical 4-SMD 6.00x3.50mm package dimensions.
