Crystals Procurement Notes

Verify the specific suffix 'CDT' against the manufacturer's official datasheet to confirm exact tolerance and packaging specifications. Ensure the design-in load capacitance matches the component's 18pF rating. Confirm RoHS3 compliance status directly from the latest production documentation before procurement.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal is required in a small 4-SMD footprint. The 18pF load capacitance and 100 Ohm ESR must align with the oscillator circuit design. Consider the ±15ppm stability requirement relative to system timing accuracy needs.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages optimized for space-constrained designs. The 402F250XXCDT specifically targets applications requiring a 25 MHz reference signal in a standard SMD form factor.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals with identical 18pF load capacitance, 100 Ohm ESR, and 4-SMD (2.00x1.60mm) dimensions. Verify pinout compatibility and mounting height constraints when evaluating alternative manufacturers.
