Crystals Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact physical dimensions and termination style. Ensure the selected variant matches the required PCB footprint and soldering profile. Cross-reference the ESR and load capacitance values with the target oscillator circuit design to guarantee stable startup and operation under specified environmental conditions.

Crystals Selection Notes

Select this component when a standard 3.6864 MHz reference is required for digital systems. The HC-49/US form factor offers established compatibility with common mounting pads. Consider the ±30 ppm tolerance for general timing applications where high precision is not critical. Verify that the 180 Ohm ESR aligns with the driving circuit's capability to sustain oscillation without excessive power dissipation.

Crystals Part Context

This part belongs to the 49SMT series from YIC, representing a standardized quartz crystal solution. The model number indicates the specific frequency, load capacitance, and package type within the manufacturer's catalog. It serves as a passive frequency control element essential for generating precise clock signals in electronic assemblies requiring stable timekeeping or data transmission rates.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US crystals with identical 3.6864 MHz frequency, 20 pF load capacitance, and similar ESR specifications. Verify pin compatibility and mechanical dimensions before substitution. Alternative part numbers may vary in temperature stability or aging rates; consult individual datasheets for performance equivalence.
