Crystals Procurement Notes

Verify that the specific part number matches the required frequency and package dimensions against current schematic requirements. Confirm that the supplier provides genuine components from Suntsu Electronics, Inc., as counterfeit parts may exhibit incorrect frequency or stability characteristics. Ensure the ordering suffix aligns with the desired packaging format, such as tape and reel or bulk, to match assembly line capabilities. Cross-reference the date code to ensure recent manufacturing standards are met for long-term reliability in production environments.

Crystals Selection Notes

Select this component when replacing obsolete Epson MA-306 units in existing designs without altering footprint constraints. Choose this model for applications requiring a 20 MHz reference signal within a compact 8.0 mm x 3.8 mm envelope. Consider the ±20 ppm tolerance and 40 Ohm ESR specifications to ensure compatibility with the host circuit's drive level and loading requirements. Evaluate the 0°C to +70°C operating range against the environmental conditions of the final product deployment.

Crystals Part Context

This component is part of the SXT834 series, which addresses supply chain discontinuations by offering direct replacements for legacy Epson MA-306 crystals. The series spans frequencies from 8.000 MHz to 54.000 MHz, catering to diverse timing needs. The SXT83418DA17-20.000M specifically targets the 20 MHz segment, maintaining the physical and electrical compatibility necessary for seamless integration into established hardware architectures previously dependent on the older generation components.
