Crystals Procurement Notes

Verify the specific suffix configuration against official Suntsu documentation to ensure alignment with required tolerance and temperature grades. Confirm that the 4-SMD no-lead package matches your reflow soldering profile capabilities. Cross-reference the ESR specifications with your oscillator circuit design to guarantee startup reliability under worst-case conditions. Ensure compliance with RoHS3 standards if applicable to your manufacturing region.

Crystals Selection Notes

Select this model when a 16 MHz frequency is required alongside a 20 pF load capacitance for standard microcontroller interfaces. Consider the ±30 ppm tolerance and ±50 ppm stability limits against your system's jitter budget. The industrial temperature range makes it suitable for harsh environments where commercial-grade parts may fail. Evaluate the 200 Ohm ESR limit to ensure compatibility with your driver circuit's output impedance constraints.

Crystals Part Context

This component belongs to the SXT214 series, which specializes in miniature ceramic crystals for modern electronics. The series addresses the industry trend toward miniaturization by offering a 2.0 x 1.6 mm footprint significantly smaller than traditional 2520 packages. It provides engineers with options for various load capacitors and tolerance grades within a standardized industrial temperature window.

Crystals Replacement Considerations

Direct substitutes include other SXT214 variants with identical 16 MHz frequency and 20 pF load capacitance but different tolerance codes, such as SXT21420BB48-16.000M for tighter stability. Generic replacements must match the 4-SMD no-lead package dimensions and electrical parameters precisely to avoid layout modifications.
