Crystals Procurement Notes

Verify current availability status as the product may be subject to discontinuation or limited supply conditions. Confirm that the ordering suffix corresponds to the specific package and tolerance requirements. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Check for any updated datasheet revisions that might affect mechanical dimensions or electrical parameters before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 33.8688 MHz reference signal is required for automotive or industrial applications. The HC-49/S SMD form factor offers a balance between traditional crystal performance and modern surface mount assembly needs. Consider the ±30 ppm tolerance for standard clock generation tasks where high precision is not critical. Verify that the 10 pF load capacitance matches the oscillator circuit design specifications.

Crystals Part Context

This part belongs to the AT series of crystals from TXC Corporation, which are known for their robust construction and wide temperature operation capabilities. The AT series typically employs glass-sealed quartz elements to provide stable frequency output over varying environmental conditions. This specific model represents a transition from through-hole to surface mount packaging while maintaining the electrical characteristics associated with the HC-49/S form factor.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the specific combination of frequency, tolerance, package style, and AEC-Q200 certification, direct replacements must be sourced from official manufacturer cross-reference lists or verified distributors. Ensure any alternative component meets the same electrical and mechanical specifications.
