Crystals Procurement Notes

Verify the specific suffix 'XIAT' against the official CTS datasheet to confirm the exact load capacitance and temperature range, as suffix variations within the 402 series may alter electrical parameters. Ensure compatibility with the target circuit's oscillator requirements before procurement. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints.

Crystals Selection Notes

Select this component when a 20.48 MHz reference with ±10 ppm tolerance is required in a compact surface-mount form factor. The 10 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range suitability for the intended environment. Verify that the hermetic package meets the reliability standards of the application compared to non-hermetic alternatives.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers sub-miniature surface mount crystals. The series provides various frequency options and package sizes, ranging from 1.6mm x 1.2mm to larger footprints. The 402 series is designed for high-volume manufacturing applications requiring reliable frequency control in consumer electronics and industrial equipment.

Crystals Replacement Considerations

Direct substitutes include other 402 series variants with identical 20.48 MHz frequency, 10 pF load capacitance, and ±10 ppm tolerance. Verify that alternative parts match the 4-SMD package dimensions and ESR specifications to ensure pin-to-pin and performance compatibility without circuit modification.
