Crystals Procurement Notes

Verify the specific suffix 'IAT' against official CTS documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the target circuit design accommodates the 10pF load capacitance and 120 Ohm ESR specifications. Confirm that the 4-SMD footprint matches the PCB layout requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a precise 19.2 MHz fundamental frequency is required with tight ±10 ppm stability. It is suitable for applications demanding small form factors due to its 2.00mm x 1.60mm SMD package. Consider the -40°C to +85°C operating range for industrial environments requiring robust thermal performance.

Crystals Part Context

This part belongs to the CTS 402 Series of general-purpose quartz crystals. The series offers various frequency options and package styles, providing designers with standardized components for embedded systems. The 402F1921XIAT specifically addresses the need for high-stability timing in space-constrained surface-mount designs.

Crystals Replacement Considerations

Direct substitutes include 402F1921XILR and 402F1921XIKR from CTS-Frequency Controls. These alternatives share identical electrical parameters but may differ in packaging or suffix specifications. Verify compatibility with existing manufacturing processes before substitution.
