Crystals Procurement Notes

Verify the specific suffix FA38 corresponds to the required 4-SOJ package configuration and pinout compatibility with your PCB footprint. Confirm that the 150 Ohm ESR specification aligns with your oscillator circuit design requirements. Ensure the ±10ppm tolerance meets the system clock accuracy needs. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Crystals Selection Notes

Select this component when a 4.9152 MHz reference is required with moderate stability. The 20pF load capacitance must match the external capacitors in the oscillator circuit. Consider the SOJ package dimensions for board space constraints. Evaluate the -30°C to +85°C range against environmental conditions. Compare ESR limits with driver capability to ensure reliable oscillation start-up.

Crystals Part Context

This part belongs to the SXT144 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The SXT14420FA38 variant specifically denotes the 4-SOJ form factor. Other variants in the series may differ in frequency, tolerance, or package type. This model provides a standardized solution for timing applications requiring specific frequency points.

Crystals Replacement Considerations

Direct substitutes include other SXT14420FA38 models with identical frequency but different tolerances if looser specs are acceptable. Cross-reference with other manufacturers offering 4-SOJ crystals at 4.9152 MHz with 20pF load. Verify pin compatibility and mechanical dimensions before substitution. Ensure electrical parameters like ESR and drive level remain within safe operating limits.
