Crystals Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the specific HC-49/US package dimensions and electrical parameters. Check for valid RoHS3 compliance documentation. Ensure storage conditions prevent moisture damage prior to soldering. Validate part markings against the official datasheet specifications.

Crystals Selection Notes

Select this component when a 3.6864 MHz fundamental frequency is required for digital logic timing. The 18 pF load capacitance must match the oscillator circuit design requirements. Consider the ±50 ppm stability tolerance for applications where high precision is not critical. The HC-49/US SMD form factor suits space-constrained PCB layouts compared to through-hole alternatives.

Crystals Part Context

This crystal belongs to the 9C series from TXC Corporation, which specializes in surface-mount quartz crystals. The series offers various frequency options optimized for consumer electronics and industrial applications. The 9C03600039 specifically targets cost-sensitive designs requiring reliable frequency control without the complexity of active oscillators.

Crystals Replacement Considerations

Direct substitutes include other 3.6864 MHz crystals with identical 18 pF load capacitance and HC-49/US footprint. Verify ESR compatibility to ensure oscillator startup reliability. Cross-reference pinout and mechanical dimensions to confirm PCB compatibility before substitution.
