Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and tolerance specifications. Confirm that the surface-mount variant matches the required PCB footprint dimensions. Check current availability status as distribution may vary. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 14.7456 MHz reference is required for serial communication interfaces. The ±20ppm tolerance supports standard baud rates like 115200 without significant cumulative error. Consider the 18pF load capacitance requirement for oscillator circuit design. The HC-49/US-SM form factor allows for space-constrained surface-mount layouts while maintaining reliability within the specified temperature range.

Crystals Part Context

This part belongs to the general category of MHz crystals produced by CTS-Frequency Controls. It serves as a passive frequency control element distinct from active oscillators. The HC-49/US-SM package represents a surface-mount adaptation of the traditional through-hole crystal housing, enabling modern PCB manufacturing techniques while retaining familiar mechanical characteristics.

Crystals Replacement Considerations

Consult official substitution lists for direct replacements. Verify that any substitute maintains identical frequency, load capacitance, and ESR values. Ensure the replacement package matches the HC-49/US-SM dimensions for board compatibility.
