Crystals Procurement Notes

Verify the specific suffix 'CAR' against the manufacturer's current datasheet to confirm active status and exact electrical tolerances. Check for recent lifecycle changes or obsolescence notices from CTS-Frequency Controls. Ensure compatibility with the target circuit's load capacitance requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with 10 pF load capacitance is required. Consider the 60 Ohm ESR value for oscillator circuit design. The commercial temperature range (-20°C to +70°C) dictates suitability for standard consumer electronics rather than harsh industrial environments requiring extended ranges.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package sizes optimized for space-constrained designs. The 402F50011CAR specifically targets applications needing stable 50 MHz timing in a small form factor, distinguishing it from larger through-hole or older SMD variants.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 402F50011CAT, 402F50011CJR, and 402F50011CKR. These alternatives share similar specifications but may differ in packaging suffixes or specific manufacturing lot details. Verify pin-out and electrical parameters match the original design requirements.
