Crystals Procurement Notes

Verify the specific suffix IJR against official CTS documentation to confirm lead time and availability status, as distribution channels may vary. Ensure compatibility with existing PCB footprints and reflow profiles. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS3 compliance requirements match project specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency with 9 pF load capacitance is required. Consider the ±10 ppm tolerance for applications needing tighter initial accuracy compared to standard ±20 ppm parts. Evaluate the 4-SMD package size constraints against available board space. Verify that the -40°C to +85°C operating range meets the environmental conditions of the target application.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and package sizes optimized for consumer electronics and industrial controls. The 402F27112IJR specifically utilizes the smaller 2.00mm x 1.60mm form factor, distinguishing it from larger legacy packages while maintaining similar electrical characteristics within the family.

Crystals Replacement Considerations

Direct substitutes include 402F27112IAR and 402F27112IDT from CTS-Frequency Controls. These alternatives share identical electrical parameters but may differ in packaging suffixes or reel configurations. Verify pin-out compatibility and mechanical dimensions before substitution.
