Crystals Procurement Notes

Verify the specific suffix ILR corresponds to tape-and-reel packaging requirements for your manufacturing line. Confirm that the ±10 ppm stability meets system timing budgets. Ensure PCB land patterns match the 2.00mm x 1.60mm outline. Check current availability status as supply levels fluctuate. Validate RoHS3 compliance if required by end-product regulations.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with high stability is required. Compare ESR values against oscillator circuit designs to ensure proper startup. Consider the 12pF load capacitance compatibility with host device specifications. Evaluate thermal performance within the specified -40°C to +85°C range. Assess physical space constraints against the small SMD package dimensions.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals. The series offers various frequencies and packages. The 402F50012ILR specifically targets applications needing stable 50 MHz timing in compact layouts. It shares design characteristics with other 402 series variants differing in frequency or tolerance.

Crystals Replacement Considerations

Direct substitutes include 402F50012IAR and 402F50012IJR from CTS-Frequency Controls. These alternatives share identical electrical parameters but may differ in packaging format. Verify package compatibility before substitution. Other manufacturers' parts require full parameter matching including ESR and load capacitance.
