Crystals Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. Confirm the specific frequency tolerance and stability requirements align with the system design specifications before procurement. Ensure compatibility with standard reflow soldering profiles for surface-mount components.

Crystals Selection Notes

Select this component when a 38.4 MHz reference signal is required with tight frequency control. Consider the 10 pF load capacitance requirement for circuit matching. Evaluate the thermal performance needs against the specified -40°C to +85C operational range.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same form factor and mounting style as other variants within the series but differs in frequency and electrical parameters. The XIAR suffix typically denotes the tape and reel packaging option.

Crystals Replacement Considerations

The 402F3841XIKR is a confirmed substitute offering identical electrical specifications and frequency performance. Verify package compatibility and ensure the alternative variant meets the same thermal and stability requirements.
