Crystals Procurement Notes

Verify the specific suffix 'ILT' against the official CTS datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the ordering part number matches the required frequency code table entry for 37.4 MHz. Confirm that the supplier provides traceability documentation for automotive-grade components if AEC-Q200 compliance is required for the final assembly.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental resonance is required with tight ±20ppm stability. The 12pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The 4-SMD footprint requires adequate solder paste stencil design for reliable reflow attachment without tombstoning.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series is designed for general-purpose timing applications requiring small form factors. The 402F37412ILT specifically targets high-volume consumer and industrial markets where consistent performance across wide temperature ranges is critical for system synchronization.

Crystals Replacement Considerations

Direct substitutes include 402F3741XILR and 402F37412ILR from CTS-Frequency Controls. These parts share identical electrical parameters and mechanical dimensions. Verify that any alternative maintains the same 12pF load capacitance and 60 Ohm ESR to ensure circuit compatibility.
