Crystals Procurement Notes

Verify the specific suffix 'CJT' against official CTS documentation to confirm the exact load capacitance and ESR values, as variations exist within the 402 series. Confirm availability status, as this part may be discontinued or subject to limited supply. Ensure the receiving facility handles surface mount components according to standard moisture sensitivity level protocols prior to assembly.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental mode crystal is required with a 9 pF load capacitance. Consider the ±30 ppm stability requirement relative to system clock accuracy needs. Evaluate the 4-SMD footprint compatibility with PCB layout constraints. Compare ESR specifications against oscillator circuit drive levels to ensure proper startup and stable operation within the specified temperature range.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals, which are known for providing reliable frequency control in compact electronic designs. The series offers various frequency codes and package options to meet diverse application requirements. The 402F20433CJT specifically addresses the need for a standard 20.48 MHz reference in space-constrained surface mount assemblies.

Crystals Replacement Considerations

Direct substitutes include other 402 series variants with identical electrical parameters, such as different packaging suffixes if available. Verify that any replacement maintains the 20.48 MHz frequency, 9 pF load capacitance, and 100 Ohm ESR. Check for updated manufacturing statuses or obsolescence notices from CTS before switching.
