Crystals Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify end-of-life status and final time buy requirements before procurement. Ensure replacement strategies are defined due to discontinuation. Confirm RoHS3 compliance and MSL level 1 handling requirements during storage and assembly. Cross-reference datasheets for any product change notices affecting pinout or electrical characteristics.

Crystals Selection Notes

Select this part only if the specific 35.328 MHz frequency and HC-49/US form factor are mandatory for the design. Consider the ±50ppm stability requirement against application needs. Evaluate the 80 Ohm ESR value for oscillator circuit compatibility. Due to obsolete status, prioritize alternative sources or qualified substitutes immediately.

Crystals Part Context

The 9C series represents TXC Corporation's line of miniature surface-mount crystals. This model belongs to the HC-49S variant family, designed for cost-effective timing solutions. It serves as a passive frequency-determining element in oscillator circuits, replacing through-hole variants with a compact surface-mount profile suitable for modern PCB layouts.

Crystals Replacement Considerations

Public confirmed substitute: QT49S-35.328MBBK-T by QST. Verify parameter equivalence including frequency, load capacitance, ESR, and package dimensions before integration.
