Crystals Procurement Notes

Verify the specific suffix 'CAT' against official CTS documentation to confirm the exact load capacitance and packaging configuration, as suffixes define critical electrical parameters. Confirm current availability status directly with the manufacturer or authorized distributors, as this part number may be subject to discontinuation or supply constraints. Ensure the selected variant matches the required PCB footprint and thermal specifications for the target application environment.

Crystals Selection Notes

Select this component when a 50 MHz fundamental resonance is required with a 10pF load capacitance. The 4-SMD no-lead form factor suits space-constrained surface mount designs. Verify that the circuit design supports the specified 60 Ohm ESR and that the operating temperature range of -20°C to +70°C aligns with the system's environmental requirements. Consider alternative suffixes if different load capacitances are needed.

Crystals Part Context

This crystal belongs to the CTS 402 Series, which offers various fundamental mode crystals in compact SMD packages. The series provides options for different frequencies, load capacitances, and stability grades. The 402F50011CAT specifically addresses applications requiring precise 50 MHz timing in a small footprint. Other variants in the series differ primarily in frequency, capacitance, and physical dimensions while maintaining similar mounting styles.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 402F50011CJR and 402F50011CKR from CTS-Frequency Controls. These alternatives share the same 50 MHz frequency and package type but differ in load capacitance values. Verify compatibility with the existing circuit's load capacitance requirements before substitution.
