Crystals Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 18.432 MHz frequency and 20 pF load capacitance. Confirm the package dimensions are compatible with the target PCB footprint. Ensure the industrial temperature rating meets the environmental requirements of the final assembly. Check for RoHS compliance status as indicated in supplier documentation.

Crystals Selection Notes

Select this component when a precise 18.432 MHz timing reference is required for digital logic circuits. The 20 pF load capacitance must match the system's external capacitor configuration. Consider the 60 Ohm ESR limit for oscillator circuit compatibility. The SMD form factor is suitable for automated assembly processes requiring small footprints.

Crystals Part Context

This crystal belongs to the ECX-64A series from ECS Inc., designed for high-volume surface-mount manufacturing. It serves as a fundamental frequency control element in synchronous digital systems. The component replaces through-hole variants where space constraints necessitate a low-profile SMD solution while maintaining standard quartz stability characteristics.

Crystals Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 20 pF load capacitance, and 6.00x3.50mm package size. Verify equivalent ESR and frequency stability ratings. Cross-reference with other manufacturers' 18.432 MHz SMD crystals ensuring identical pinout and thermal performance.
