Crystals Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation to ensure compliance with project requirements. Confirm that the HC-49/S footprint matches the target PCB design constraints. Check for any RoHS or REACH compliance documentation updates from the manufacturer prior to final procurement approval.

Crystals Selection Notes

Select this component when a through-hole crystal with 20 pF load capacitance is required for 8 MHz applications. Ensure the circuit design accommodates the 30 Ohm series resistance limit. Consider thermal stability requirements against the specified ±50 ppm tolerance before finalizing the bill of materials.

Crystals Part Context

This part belongs to the 9B series of crystals from TXC Corporation, which are widely used in consumer electronics and industrial equipment. The HC-49/S package is a legacy but reliable form factor for through-hole assembly, offering robust mechanical stability compared to surface-mount alternatives.

Crystals Replacement Considerations

Direct substitutes include other 8 MHz HC-49/S crystals with matching 20 pF load capacitance and ±50 ppm stability. Verify equivalent series resistance and drive level specifications to ensure circuit compatibility.
