Crystals Procurement Notes

Verify the specific suffix DC17 against the manufacturer's official datasheet to confirm the exact package dimensions and pin configuration. Ensure the load capacitance requirement of your circuit matches the 19pF specification to maintain frequency accuracy. Confirm that the operating temperature range of -10°C to +70°C aligns with your environmental constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with moderate stability needs. The 19pF load capacitance must match the oscillator circuit design to prevent frequency drift. Consider the 60 Ohm ESR limit to ensure proper oscillation startup conditions. Verify that the commercial temperature range suffices for the intended application environment.

Crystals Part Context

This part belongs to the SXT22419 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies with consistent packaging and electrical characteristics. The DC17 suffix typically denotes specific mechanical or material attributes within this product line, distinguishing it from other variants like AA17 or DD17 which may have different temperature ranges or stability ratings.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 19pF load capacitance and 4-SMD no-lead footprint. Verify that replacement parts meet the same ±20 ppm tolerance and 60 Ohm ESR requirements. Ensure the alternative component supports the -10°C to +70°C operating range for equivalent thermal performance.
