Crystals Procurement Notes

Verify the specific ordering suffix EA4A against the manufacturer's current datasheet to ensure compatibility with required load capacitance and mounting specifications. Confirm that the 4-SMD no-lead package aligns with the target PCB footprint and reflow soldering profile requirements. Cross-reference the ±15ppm tolerance requirement with system design constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required with tight initial accuracy. The low ESR of 150 Ohms supports efficient oscillator circuit design. Ensure the application environment stays within the specified -40°C to +105°C range to maintain the stated ±50ppm stability. Compare against larger packages if higher power handling or different mechanical robustness is needed.

Crystals Part Context

This part belongs to the SAX214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and package sizes optimized for space-constrained electronics. The SAX21410EA4A variant specifically targets high-volume consumer and industrial devices requiring reliable frequency control in a minimal footprint.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 2.0x1.6mm footprints and 10pF load capacitance. Verify pin compatibility and electrical parameters such as ESR and stability before swapping.
