Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and frequency tolerance specifications. Confirm that the HC-49S SMD footprint matches the target PCB design constraints. Ensure supply chain sources provide valid documentation regarding RoHS compliance and material composition certificates prior to final procurement authorization.

Crystals Selection Notes

Select this component when a durable metal-can surface-mount crystal is required for 8 MHz applications. The 18 pF load capacitance must align with the oscillator circuit design parameters. Consider the 80 Ω series resistance and 1 µW drive level limits to prevent over-driving the crystal. Verify that the -20°C to +70°C operating range satisfies the environmental conditions of the intended application environment.

Crystals Part Context

This part belongs to the TXC 9C series of surface-mount quartz crystals. It utilizes the widely adopted HC-49S form factor adapted for surface mounting, offering a balance between mechanical stability and compact board space. The series is designed for general electronic applications where reliable frequency control is essential without the need for specialized automotive or industrial certifications.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49S SMD crystals with identical 8 MHz frequency, 18 pF load capacitance, and 30 ppm tolerance. Verify pin compatibility and physical dimensions before substitution. Cross-reference electrical characteristics such as ESR and drive level sensitivity to ensure circuit performance remains unaffected.
