Crystals Procurement Notes

Verify the specific suffix EA27 corresponds to the required load capacitance and tolerance grade. Confirm that the 4-SOJ package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the datasheet for any recent revisions affecting electrical parameters or mechanical tolerances before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a fundamental mode crystal with moderate accuracy is required for industrial environments. The 12 MHz frequency suits many microcontroller and serial communication interfaces. Consider the 18 pF load capacitance to minimize external matching components. Evaluate the ±15 ppm tolerance against system jitter requirements. Compare against higher precision options if tighter frequency stability over temperature is necessary for the application.

Crystals Part Context

This part belongs to the SXT144 series of surface-mount crystals from Suntsu Electronics. The series provides alternatives to discontinued legacy parts, maintaining similar form factors to reduce design modifications. It targets applications needing robust performance in consumer, industrial, and automotive sectors. The SXT144 line emphasizes ease of integration through standardized pin pitches and widely available frequency points.

Crystals Replacement Considerations

The SWS144 series serves as a direct replacement for discontinued 32.768 kHz crystals, but differs in frequency and package. For direct functional substitution, verify compatibility with other SXT144 variants sharing the same package and electrical characteristics. No specific cross-model substitutes are documented for this exact 12 MHz configuration.
