Crystals Procurement Notes

Verify the specific suffix 'ILR' corresponds to tape-and-reel packaging when sourcing. Confirm that the ±10 ppm tolerance meets system requirements, as other variants like 402F2041XILR may offer different tolerances. Check current availability status as supply chain conditions fluctuate. Ensure EDA models match the exact package dimensions for accurate PCB footprint design.

Crystals Selection Notes

Select this part when a 20.48 MHz reference with tight ±10 ppm initial accuracy is required. Compare against 402F2041XILR if looser tolerance is acceptable. Consider 402F20412ILT if leaded termination is preferred over SMD. Verify load capacitance compatibility with the oscillator circuit's input capacitance to ensure frequency accuracy.

Crystals Part Context

This component belongs to the CTS 402 series of miniature crystals. The series offers various frequencies and packages optimized for consumer electronics and industrial applications. The 402F20412ILR specifically targets applications requiring stable clock signals in space-constrained designs.

Crystals Replacement Considerations

Direct substitutes include 402F2041XILR and 402F20412ILR from CTS-Frequency Controls. Parameter-equivalent options are available but require verification of electrical characteristics. Ensure any replacement matches the 4-SMD package dimensions and pin configuration.
