Crystals Procurement Notes

Verify the specific suffix CLT against official CTS documentation to confirm tape and reel packaging configuration. Confirm that the 402F40011CLT designation aligns with the required 12pF load capacitance and 40MHz frequency code. Cross-reference the manufacturer's current lifecycle status, as availability may be limited or discontinued in certain regions. Ensure the selected variant matches the -20°C to +70°C temperature rating required for the target application environment.

Crystals Selection Notes

Select this component when a 40MHz fundamental frequency with ±10ppm stability is required in a compact 2.0x1.6mm footprint. The 12pF load capacitance must match the oscillator circuit design specifications. Consider the 60 Ohm ESR value for impedance matching requirements. This part is suitable for commercial temperature ranges (-20°C to +70°C). Verify compatibility with standard SMT reflow profiles and ensure the 4-SMD no-lead package fits within the allowable board space constraints.

Crystals Part Context

This component belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series offers various frequency codes and package options for timing applications. The 402F40011CLT specifically denotes the 40MHz frequency code with the CLT suffix indicating the specific packaging type. It shares the same physical footprint and electrical characteristics as other variants in the 402 series, differing primarily in frequency and packaging suffixes.

Crystals Replacement Considerations

Publicly listed parameter-equivalent substitutes include 416F40011CDR. Note that the 416 series typically uses a smaller 1.6x1.2mm package compared to the 402 series 2.0x1.6mm footprint. Verify mechanical fit and soldering profile compatibility before substitution. Other similar parts like 416F40011CAR are also listed but require verification of exact electrical equivalence.
