Crystals Procurement Notes

Verify the exact frequency tolerance and stability specifications against the official Suntsu Electronics datasheet prior to procurement. Ensure the selected variant matches the required operating temperature range and load capacitance for your specific circuit design. Confirm package dimensions and soldering profiles align with your manufacturing capabilities. Cross-reference the part number suffixes to guarantee compatibility with your system requirements.

Crystals Selection Notes

Select this component when a 27 MHz fundamental crystal with ±20ppm initial tolerance is required. Consider the 150 Ohm ESR limit for oscillator circuit design to ensure proper startup. Evaluate the -10°C to +70°C operating range against environmental conditions. The 4-SMD package suits high-volume surface mount applications. Compare load capacitance requirements with existing circuit designs to avoid frequency deviation.

Crystals Part Context

This part belongs to the Suntsu Electronics crystal family, specifically designed for surface mount applications. It shares the 4-SMD no lead form factor with other models in the series but differs in frequency and electrical parameters. The SXT1147DA27-27.000M is distinct from variants like the SXT1147DD17 or SXT1147DA17 which may have different tolerances or packaging details. It serves as a timing element in systems requiring fixed frequency references.

Crystals Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 7pF load capacitance, and 4-SMD package. Verify that alternative crystals offer equal or better frequency stability and ESR ratings. Check if competitor parts support the same operating temperature range. Ensure pinout compatibility for surface mount reflow processes. Consult manufacturer cross-reference guides for verified equivalents.
