Crystals Procurement Notes

Verify the specific manufacturing date code against the project timeline, as this component may be subject to end-of-life status or discontinuation notices from the manufacturer. Confirm that the HC-49/US package dimensions align precisely with the existing PCB land pattern to ensure proper solder joint formation during reflow processes.

Crystals Selection Notes

Select this part when a 37.5 MHz reference is required in a surface-mount design. Ensure the circuit load matches the 12 pF specification to maintain accuracy. Verify that the ±30 ppm stability meets the system timing requirements and that the -20°C to +70°C operating range covers the intended environmental conditions without requiring industrial-grade alternatives.

Crystals Part Context

This component belongs to the 9C series of crystals manufactured by TXC Corporation. The series is characterized by its focus on cost-effective solutions for high-volume consumer electronics. These parts are widely used in mass-produced devices where standard timing frequencies and reliable commercial-grade performance are prioritized over extreme environmental robustness.

Crystals Replacement Considerations

Direct substitutes include other 37.5 MHz crystals in the HC-49/US package with matching 12 pF load capacitance. Cross-reference datasheets to confirm identical electrical parameters and mechanical dimensions before integration.
