Crystals Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to limited supply chains. Confirm that the HC-49/US package dimensions align with existing PCB footprints. Ensure the 30 pF load capacitance matches the oscillator circuit requirements. Check for updated replacement recommendations from the manufacturer if production is no longer active.

Crystals Selection Notes

Select this component when a robust, through-hole crystal is required for 4 MHz applications. The HC-49/US form factor provides mechanical durability suitable for environments where surface-mount options are unsuitable. The ±30 ppm stability is adequate for standard digital logic timing but may require tighter specifications for high-precision communication interfaces.

Crystals Part Context

This component belongs to the 9B series of MHz crystals manufactured by TXC Corporation. The series focuses on providing cost-effective, general-purpose timing solutions using traditional through-hole technology. These units are commonly utilized in legacy designs and consumer electronics where space constraints are less critical than component longevity and ease of assembly.

Crystals Replacement Considerations

Public records indicate this product has been marked as obsolete. Users should consult official distributor channels for confirmed substitute part numbers or next-generation replacements from TXC Corporation that maintain compatible electrical parameters and package dimensions.
