Crystals Procurement Notes

This component is officially discontinued by the manufacturer. Verify end-of-life status through official channels before design finalization. Sourcing may be limited to surplus or secondary markets. Confirm RoHS compliance details via current documentation. Evaluate alternative components for new production runs to ensure long-term supply chain stability.

Crystals Selection Notes

Select this part only if the specific 18.432 MHz frequency and HC-49/US footprint are mandatory. Note that the ±50ppm stability is standard, not high precision. Ensure circuit design accommodates the 20pF load requirement. Consider newer series from the manufacturer for improved availability and potentially tighter tolerances.

Crystals Part Context
