Crystals Procurement Notes

Verify the exact specifications against the official product datasheet before procurement, as images may serve only as representations. Confirm that the HC-49S 2-DIP package and 200 Ohm ESR parameters align with your circuit design requirements. Ensure compatibility with the 5.5296 MHz frequency and ±20ppm tolerance for your specific application environment.

Crystals Selection Notes

Select this component when a 5.5296 MHz reference is required in a standard through-hole format. The 20pF load capacitance must match the oscillator circuit design. Consider the 200 Ohm ESR value for drive level sensitivity. This part suits applications where the HC-49S footprint is available and preferred over surface-mount alternatives like the X49SS2 series.

Crystals Part Context

This model belongs to the quartz frequency control component portfolio of Suzhou Hangjing Elec & Tech Co., Ltd. The company focuses on full-cycle R&D and production of crystals, oscillators, and filters. The 049ST2 series represents their standard dip-mounted crystal offerings, distinct from their surface-mount X49SS2 line which shares similar electrical characteristics but differs in physical packaging.

Crystals Replacement Considerations

The X49SS2-5.5296-F20LJDTK offers identical electrical specifications including 5.5296 MHz frequency, 20pF load capacitance, and ±20ppm tolerance. However, it utilizes an SMD package rather than the HC-49S DIP form factor. Substitution requires PCB layout modification to accommodate the different physical dimensions.
