Crystals Procurement Notes

Verify the specific suffix 'IAT' against manufacturer documentation to confirm exact load capacitance and tolerance specifications, as suffix variations may alter electrical parameters. Confirm availability status directly with CTS-Frequency Controls or authorized distributors, as supply chain conditions change frequently. Ensure the selected variant matches the required PCB land pattern dimensions of 2.00mm x 1.60mm for proper assembly.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency with tight ±10ppm tolerance is required. The 10pF load capacitance must match the oscillator circuit design. Consider the 120 Ohm ESR value for drive level sensitivity. The 4-SMD package requires appropriate reflow soldering profiles. Verify that the -40°C to 85°C temperature range meets the operational environment requirements.

Crystals Part Context

This part belongs to the CTS 402 Series of MHz crystals, which are characterized by small surface-mount packages and fundamental mode operation. The series provides various frequency options and load capacitance values to support diverse embedded system timing needs. The 402F19212IAT specifically addresses applications requiring precise 19.2 MHz timing with standard commercial temperature ranges.

Crystals Replacement Considerations

Direct substitutes include parts from the same 402 series with matching electrical parameters. Verify package compatibility and pin configuration before substitution. Cross-reference load capacitance and ESR values to ensure circuit stability.
