Crystals Procurement Notes

Verify the specific suffix 'AAR' against the manufacturer's current datasheet to confirm availability status, as distribution channels may list obsolete or discontinued variants. Ensure the ordering part number matches the required load capacitance and tolerance specifications for the target application circuit design before finalizing procurement actions.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±30ppm tolerance is required in a compact 1.6x1.2mm footprint. Confirm that the system oscillator circuit can accommodate the 60 Ohm ESR and 10pF load capacitance requirements. Verify compatibility with the -40°C to +85°C operating temperature range for the intended environment.

Crystals Part Context

This part belongs to the CTS 416 Series of miniature surface mount crystals. The series provides various frequency options in a standardized small outline package format. The 416F40033AAR specifically addresses applications needing a 40 MHz output with moderate precision in space-constrained designs.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 416F40033AKT and 416F40033IKR from CTS-Frequency Controls. These alternatives share identical electrical specifications and mechanical dimensions, allowing for direct pin-compatible replacement if the original part is unavailable.
