Crystals Procurement Notes

Verify the specific suffix 'IAR' against official datasheets to confirm the 10pF load capacitance and 100 Ohm ESR parameters, as variations exist within the 402 series. Confirm availability status directly with the manufacturer or authorized distributors, as supply chain conditions may affect lead times and stock levels. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±20ppm stability is required in a compact 2.0x1.6mm package. The 10pF load capacitance and 100 Ohm ESR must match the oscillator circuit design specifications. Consider the -40°C to +85°C operating range for industrial applications. Verify that the 4-SMD no-lead package aligns with the board layout constraints and manufacturing capabilities.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls, designed for general-purpose timing applications. The series offers various frequencies and packages, with the 402F25022IAR specifically providing a 25 MHz output in a small form factor. It is distinct from other series like the 416, which may feature different dimensions or electrical characteristics such as lower ESR values.

Crystals Replacement Considerations

Direct substitutes include 402F25022ILR and 402F25022IJR from CTS-Frequency Controls. Parameter-equivalent alternatives are 402F25012ILR and 402F2501XILR. Verify that any replacement maintains the 10pF load capacitance and 100 Ohm ESR to ensure circuit compatibility.
