Crystals Procurement Notes

Verify the specific suffix CA38 against official Suntsu documentation to confirm package type and electrical characteristics. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm availability status as supply chain fluctuations may affect stock levels. Cross-reference pinout diagrams with target PCB layout requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 20 MHz reference with ±25 ppm stability is required within a 3.2x2.5mm footprint. Consider the 12pF load capacitance requirement for circuit matching. Evaluate the -30°C to +85°C range against application thermal constraints. Compare ESR specifications with oscillator circuit design limits to ensure proper startup and sustainment.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages tailored for consumer electronics and industrial applications. The CA38 suffix typically denotes specific dimensional and mounting characteristics within this product line, distinguishing it from other variants like BA or CC series components.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12pF load capacitance, and 4-SMD package dimensions. Verify that alternative parts support the same ±25 ppm tolerance and -30°C to +85°C operating range. Check for identical ESR values to prevent oscillation failure. Consult manufacturer cross-reference lists for officially approved replacements.
