Crystals Procurement Notes

Verify that the ordered component matches the specific HC-49S-SMD package dimensions and pin configuration required by the target PCB footprint. Confirm that the 20 pF load capacitance aligns with the oscillator circuit design specifications to ensure accurate frequency performance. Ensure the supplier provides documentation confirming the -40°C to +85°C operating range compliance for the intended application environment.

Crystals Selection Notes

Select this component when a surface-mount passive crystal is required for 4.096 MHz applications. The HC-49S-SMD form factor offers a balance between mechanical robustness and space efficiency compared to through-hole variants. The ±20 ppm tolerance is suitable for general timing purposes where high-precision oven-controlled stability is not mandatory. Consider the liquid metal coating for improved durability in industrial settings.

Crystals Part Context

This part belongs to the SCTF SXMH series of passive crystals. The series includes various frequencies such as 12.000 MHz and 4.096 MHz, all sharing similar HC-49S-SMD packaging characteristics. The model number encodes key parameters including frequency, load capacitance, and package type, facilitating identification within the manufacturer's catalog of surface-mount resonators.

Crystals Replacement Considerations

Direct substitutes must match the 4.096 MHz frequency, 20 pF load capacitance, and HC-49S-SMD package. Verify that alternative components offer equivalent ±20 ppm tolerance and -40°C to +85°C operating ranges. Ensure the replacement maintains the same physical pinout and mounting profile to avoid PCB redesign.
