Crystals Procurement Notes

Verify current availability status as the part may be discontinued or out of stock. Confirm that the 10pF load capacitance matches the target circuit design requirements. Ensure the ±30ppm stability meets system timing accuracy specifications. Check for direct substitute part numbers if this specific variant is unavailable.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental mode crystal is required in a small 2.00x1.60mm SMD footprint. Ensure the application environment stays within the -20°C to +70°C operating range. Verify that the 100 Ohm ESR is compatible with the oscillator circuit's drive level constraints.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls, designed for general-purpose timing applications. It shares the same physical package dimensions as other variants in the series but differs in electrical parameters such as frequency and load capacitance.

Crystals Replacement Considerations

Direct substitutes include 402F20411CAR, 402F20412IAR, 402F204XIAR, and 402F20422IAR from CTS-Frequency Controls. These alternatives share similar form factors but may have different load capacitances or tolerances requiring circuit verification.
