Crystals Procurement Notes

Verify the specific suffix 'MAHH' against official TXC documentation to confirm the exact load capacitance and tolerance parameters. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the HC-49/S package dimensions match the target PCB footprint requirements before finalizing orders.

Crystals Selection Notes

Select this component when a fundamental frequency crystal with tight ±15 ppm stability is required for through-hole assembly. The HC-49/S package offers mechanical robustness suitable for industrial applications. Consider the -20°C to +70°C operating range to ensure performance compatibility with the intended environmental conditions.

Crystals Part Context

This part belongs to the TXC 9B series of general-purpose quartz crystals. The series is characterized by its standardized HC-49/S form factor, widely adopted in legacy and modern electronics for cost-effective timing solutions. The 9B designation indicates specific manufacturing standards regarding frequency control and aging rates defined by the manufacturer.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/S crystals with identical 4.000 MHz frequency, 15 pF load capacitance, and ±15 ppm tolerance. Verify equivalent ESR and drive level specifications to maintain circuit oscillation reliability.
