Crystals Procurement Notes

Verify the specific suffix and packaging variant against the official datasheet before ordering, as availability may vary by region. Confirm that the HC-49/US form factor aligns with the target PCB footprint requirements. Ensure the ±50 ppm stability meets the system timing budget. Check for any end-of-life notifications or alternative package options if current stock is limited.

Crystals Selection Notes

Select this component when a robust, cost-effective through-hole solution is required for 19.2 MHz applications. The HC-49/US package offers mechanical durability suitable for industrial environments. Consider the ±50 ppm tolerance relative to the host system's clock accuracy needs. Evaluate the 20 pF load capacitance compatibility with the oscillator circuit design parameters.

Crystals Part Context

This part belongs to the 9B series of crystals from TXC Corporation, which focuses on standard frequency components for consumer and industrial electronics. The 9B series typically includes various frequencies packaged in HC-49/US housings. These components are widely used in legacy and modern designs where through-hole assembly provides necessary mechanical stability.

Crystals Replacement Considerations

Direct substitutes must match the 19.2 MHz frequency, HC-49/US package, 20 pF load capacitance, and ±50 ppm tolerance. Verify equivalent series resistance and temperature range specifications. Cross-reference manufacturer-specific pinout and mounting hole dimensions to ensure physical compatibility.
