Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended temperature range (-40°C to +85°C) compared to standard variants. Confirm the 12pF load capacitance matches the target oscillator circuit design requirements. Ensure the 100 Ohm ESR value is compatible with the driving circuit's power constraints. Check for RoHS3 compliance documentation if required by regulatory standards.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal is required for space-constrained designs. The 4-SMD footprint suits high-density PCB layouts. Consider the 12pF load capacitance and 100 Ohm ESR specifications against the host oscillator circuit parameters. The extended temperature range makes it suitable for industrial or automotive environments where thermal stability is critical.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series is characterized by small form factors and reliable performance for general electronic applications. The 402F2501XILT specifically denotes the 25 MHz frequency variant within this family, distinguished by its specific load capacitance and temperature rating.

Crystals Replacement Considerations

The 402F2501XIAR is listed as a similar alternative from the same manufacturer. Verify that any substitute maintains the identical 25 MHz frequency, 12pF load capacitance, and 100 Ohm ESR to ensure circuit compatibility.
