Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to ensure correct load capacitance and temperature range alignment. Confirm RoHS compliance status through authorized distributors. Request batch-specific aging rate data if long-term reliability certification is required for industrial deployments. Validate ESR specifications against circuit design constraints to prevent oscillation failure in cold environments.

Crystals Selection Notes

Select this component when a 2.0x1.6mm footprint is mandatory and 20MHz frequency is required. Ensure the system load capacitance matches the 8pF specification to maintain accuracy. Consider the ±20ppm tolerance limit for application compatibility. Evaluate the 200 Ohm ESR against the oscillator circuit's drive level capabilities to ensure stable startup conditions across the specified operating temperature range.

Crystals Part Context

This part belongs to the SXT214 series of ceramic surface-mount crystals from Suntsu Electronics. The series offers various load capacitances and frequency tolerances within a standardized small outline package. The '8' indicates 8pF load capacitance, 'D' denotes ±20ppm tolerance, 'B' signifies ±30ppm stability, and '07' represents the 0℃~+70℃ commercial temperature grade.

Crystals Replacement Considerations

Direct substitutes must match the 20MHz frequency, 8pF load capacitance, and 4-SMD 2.0x1.6mm package dimensions. Verify that alternative components meet or exceed the ±20ppm tolerance and 200 Ohm ESR limits. Check temperature range compatibility for the specific application environment.
