Crystals Procurement Notes

Verify the specific suffix 'IKR' against official CTS documentation to confirm the IoT enhanced variant specifications. Ensure the required load capacitance matches the circuit design, as this model specifies 8pF. Confirm availability status directly with authorized distributors, as supply conditions may vary. Cross-reference the package dimensions with PCB footprint requirements prior to procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with tight ±10ppm tolerance is required for IoT applications. The 8pF load capacitance distinguishes it from standard variants requiring 10pF or 12pF. Consider the 80 Ohm ESR for oscillator circuit compatibility. Verify that the 4-SMD no-lead package fits the assembly constraints and that the industrial temperature rating meets environmental demands.

Crystals Part Context

This part belongs to the 402W series of SMD crystals, specifically designed for IoT applications. Unlike the standard 402F series which typically uses 10pF or 12pF load capacitances, the 402WF series offers specialized characteristics for low-power wireless connectivity. The 'W' designation indicates the IoT enhanced feature set within the broader CTS crystal portfolio.

Crystals Replacement Considerations

Direct substitutes include other 402WF series parts with identical electrical parameters. Variants such as 402WF27012IAR or 402WF27012IJR may serve as functional equivalents if packaging differences are acceptable. Always verify that the replacement maintains the 8pF load capacitance and 80 Ohm ESR values.
