Crystals Procurement Notes

Verify the specific suffix 'W' against official documentation to confirm the 'IOT Enhanced' designation and associated electrical characteristics. Ensure the selected variant matches the required load capacitance and package dimensions for the target PCB layout. Cross-reference the manufacturer's latest datasheet to confirm current production status and RoHS compliance details.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with 8pF load capacitance is required for space-constrained designs. The 4-SMD no-lead package facilitates automated assembly. Verify that the ±10ppm tolerance meets the system clock accuracy requirements. Confirm thermal performance aligns with the -40°C to 85°C operating range.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for surface-mount technology. The 'W' suffix typically denotes specific enhancements or packaging variations within the product line, distinguishing it from standard variants like the 402F series.

Crystals Replacement Considerations

Public confirmed substitutes include 402F20012IKT and 402WF20012IKR (same part). Other similar parts may exist but require verification of load capacitance and package compatibility.
