Crystals Procurement Notes

Verify the specific suffix 'CLR' against official CTS documentation to confirm packaging and tape specifications. Ensure compatibility with existing PCB footprints matching the 2.00mm x 1.60mm outline. Confirm that the ±10 ppm stability meets system timing requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27 MHz fundamental crystal with 12 pF load capacitance is required. Compare ESR values against circuit design limits to ensure proper oscillation startup. Consider the -20°C to +70°C operating range against environmental conditions. Verify package dimensions fit within available board space constraints.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series provides various frequency options in standardized SMD packages. The 402 series is designed for general-purpose timing applications where moderate stability and small form factors are prioritized over high-performance automotive or industrial grades.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 402F27011CKT and 402F27011CAR from CTS-Frequency Controls. These alternatives share similar electrical characteristics but may differ in packaging suffixes or availability status. Verify pinout and mechanical dimensions before substitution.
