Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and operating temperature range for the target application environment. Cross-reference official documentation to validate RoHS compliance status and moisture sensitivity levels prior to procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 19.8 MHz applications with strict size constraints. Evaluate the 60 Ohm ESR against the oscillator circuit requirements to ensure proper startup conditions. Consider the ±10 ppm stability specification relative to system timing accuracy needs and verify compatibility with the host PCB layout dimensions.

Crystals Part Context

This component belongs to the 405 Series of MHz crystals manufactured by CTS-Frequency Controls. The series offers various standard frequencies in surface-mount packages suitable for industrial and commercial electronics. These crystals are designed to replace through-hole equivalents while maintaining similar electrical performance profiles for modern miniaturized designs.

Crystals Replacement Considerations

Direct substitutes may include other 19.8 MHz SMD crystals from different manufacturers provided they match the 10 pF load capacitance and 4-SMD physical dimensions. Verify pinout compatibility and mounting pad layouts before integration. Alternative packages require design modification if form factor differences exist.
