Crystals Procurement Notes

Verify the complete part number including suffixes to ensure correct load capacitance and tolerance specifications. Confirm that the required operating temperature range aligns with the -20°C to 70°C rating. Check for alternative packages if space constraints differ from the 2.00mm x 1.60mm footprint. Ensure compliance with RoHS3 requirements for your specific manufacturing environment.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with tight ±10ppm stability. The 18pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The surface-mount form factor is suitable for high-density PCB layouts where space is limited compared to through-hole alternatives.

Crystals Part Context

This crystal belongs to the 402 series from CTS-Frequency Controls, which offers various surface-mount options. The 402F38411CDT specifically targets applications needing higher stability than standard ±30ppm variants. It complements other frequencies in the series by providing a common baud rate reference point for digital systems.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with ±10ppm tolerance and 18pF load capacitance in 4-SMD packages. Verify ESR compatibility, as values like 60 Ohms may differ between manufacturers. Ensure the replacement part meets the same thermal and mechanical specifications for reliable integration.
