Crystals Procurement Notes

Verify the exact ESR value (35 Ohms vs 80 Ohms) and frequency tolerance (±20ppm vs ±30ppm) against the specific manufacturer datasheet before integration. Confirm that the HC-49S-SMD footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final application to guarantee long-term reliability.

Crystals Selection Notes

Select this component when a low-cost, surface-mount crystal is required for 11.0592 MHz applications. The HC-49S-SMD form factor provides a balance between size and mechanical robustness. Consider the specific ESR requirement of the oscillator circuit; if the circuit demands lower power consumption, verify the 35 Ohms variant is available. This part is suitable for general-purpose digital logic timing where high precision is not critical.

Crystals Part Context

This model belongs to the SCTF SXMH series of SMD crystals. It serves as a direct surface-mount replacement for through-hole HC-49U crystals, allowing for reduced board space usage. The 11.0592 MHz frequency is commonly used in serial communication interfaces to generate non-error baud rates without fractional division errors.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49S-SMD crystals with identical 11.0592 MHz frequency, 20pF load capacitance, and similar ESR ratings. Verify pin compatibility and thermal characteristics when swapping brands.
