Crystals Procurement Notes

Verify the current lifecycle status before procurement as this part may be discontinued or subject to supply constraints. Confirm that the HC-49/US through-hole footprint matches the target PCB design. Ensure the circuit supports parallel resonance configuration with the specified 12 pF load capacitance. Validate that the 80 Ohm ESR limit aligns with the oscillator driver circuit requirements.

Crystals Selection Notes

Select this component when a standard through-hole crystal is required for 48 MHz applications. The HC-49/US package offers mechanical durability suitable for industrial environments. Consider the third overtone mode if higher frequency stability is needed compared to fundamental mode crystals. Verify compatibility with the system's load capacitance and temperature range specifications.

Crystals Part Context

This part belongs to the standard quartz crystal category from TXC Corporation. It serves as a passive frequency-determining element in electronic circuits. The HC-49/US form factor is widely used in legacy and industrial designs requiring reliable through-hole integration.

Crystals Replacement Considerations

Check for direct cross-reference parts with identical HC-49/US dimensions and 48 MHz third overtone characteristics. Ensure replacement components match the 12 pF load capacitance and ±10 ppm tolerance. Verify that alternative suppliers offer comparable aging rates and ESR values.
