Crystals Procurement Notes

Verify the specific suffix EA27 against official Suntsu documentation to confirm exact tolerance and temperature grade. Distributor listings may contain conflicting specifications; rely solely on the manufacturer datasheet for electrical parameters. Ensure compatibility with reflow soldering profiles defined in the component's thermal guidelines.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required for space-constrained designs. The 12 pF load capacitance must match the circuit's external capacitor values. Consider the ±15 ppm tolerance and -20°C to +70°C range against system stability requirements before finalizing the bill of materials.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The EA27 suffix typically denotes specific tolerance and temperature characteristics within this family, distinguishing it from other variants like EE27 or standard commercial grades.

Crystals Replacement Considerations

Direct substitutes include SXT21412EE27-27.120M if wider temperature ranges are acceptable. Verify pinout and footprint compatibility with the 4-SMD no-lead package. Cross-reference load capacitance and ESR values to ensure circuit oscillation stability remains unaffected.
