Crystals Procurement Notes

Verify the specific suffix 'CDR' against official CTS documentation to confirm tape and reel packaging specifications. Ensure the selected variant matches the required 18pF load capacitance and 100 Ohm ESR parameters for circuit compatibility. Cross-reference the manufacturer part number directly with the latest datasheet to confirm current production status and availability constraints before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 20MHz fundamental crystal with ±10ppm stability is required in a small 2.0x1.6mm footprint. The 18pF load capacitance must align with the oscillator circuit design. Consider the -20°C to +70°C industrial temperature range suitability. Verify that the 100 Ohm ESR value is compatible with the host oscillator's drive level requirements to prevent over-driving or failure to start.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and packages optimized for space-constrained electronics. The 402F20011CDR specifically utilizes the 4-SMD no-lead form factor, distinguishing it from larger through-hole or different SMD variants within the broader product line.

Crystals Replacement Considerations

Publicly documented parameter-equivalent substitutes include the 402F20011CDT. Verify mechanical footprint compatibility and electrical equivalence before substitution. Alternative manufacturers may offer similar specifications but require independent validation of pinout and performance characteristics.
