Crystals Procurement Notes

Verify the specific suffix 'CKT' or 'IKT' against official datasheets to confirm packaging type and availability status. Check for obsolescence notices as distributors may list discontinued stock. Ensure compatibility with existing BOM requirements regarding moisture sensitivity level and soldering profiles before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27.12 MHz frequency is required with tight ±10ppm stability constraints. The 8pF load capacitance must match the oscillator circuit design. Consider the 4-SMD package size for space-constrained layouts. Verify temperature range suitability for the intended operational environment.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages for general-purpose timing needs. The 402F2711XIKT specifically targets applications requiring stable high-frequency reference signals in small form-factor devices.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz SMD crystals with matching 8pF load capacitance and similar ESR values. Verify pinout compatibility and physical dimensions to ensure mechanical fit within the existing PCB layout without redesign.
