Crystals Procurement Notes

Verify the specific suffix 'CKR' against official CTS documentation to confirm packaging and availability status, as distribution channels may list obsolete or discontinued variants. Ensure the selected replacement matches the 120 Ohm ESR and 8 pF load capacitance requirements to maintain circuit stability without modifying the host design.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency crystal is required for space-constrained designs. The 4-SMD footprint allows for low-profile mounting on printed circuit boards. Verify that the host oscillator circuit can drive the specified 120 Ohm ESR and that the ±10 ppm stability meets the application's timing accuracy requirements within the industrial temperature range.

Crystals Part Context

This part belongs to the CTS 402 Series of miniature crystals. The series offers various frequencies in a standardized 2.00mm x 1.60mm SMD package. The 402F16011CKR specifically addresses applications needing precise 16 MHz timing in a compact form factor, serving as a standard frequency reference for embedded systems and consumer electronics.

Crystals Replacement Considerations

Public confirmed substitutes include 402F16011CAR and 402F16011CDT from CTS-Frequency Controls. These alternatives share identical electrical parameters and mechanical dimensions, ensuring pin-compatible replacement without circuit redesign.
