Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as variants exist with different capacitance values. Confirm the ESR specification matches your oscillator circuit capabilities. Ensure the 4-SMD footprint aligns with your PCB layout constraints. Check current availability status as stock levels fluctuate. Validate that the ±30ppm stability meets your system's timing accuracy requirements.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with moderate stability. Consider the 60 Ohm ESR for oscillator drive level compatibility. Evaluate the 9pF load capacitance against the total circuit capacitance. Compare physical dimensions against available board space. Assess thermal performance within the specified operating range.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages. The 402F38433CJR specifically targets applications needing a 38.4 MHz reference. It shares the family's general SMD form factor but differs in electrical parameters like frequency and ESR compared to other models.

Crystals Replacement Considerations

Direct substitutes include parts with identical 38.4 MHz frequency, 9pF load capacitance, and 60 Ohm ESR. Verify package compatibility for 4-SMD No Lead. Check if alternative manufacturers offer equivalent specifications. Ensure frequency tolerance remains within ±30ppm limits.
