Crystals Procurement Notes

Verify the specific suffix ILR against the manufacturer's current datasheet to confirm packaging and availability status. Cross-reference the ESR value of 100 Ohms and load capacitance of 12pF with circuit requirements. Ensure the 4-SMD footprint matches the PCB layout design. Confirm compliance with RoHS3 directives if required by project specifications.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with ±20ppm stability is required in a compact SMD form factor. The 100 Ohm ESR and 12pF load capacitance must match the oscillator circuit design parameters. Consider the -40°C to 85°C operating range for environmental suitability. Verify that the 4-SMD no-lead package fits within the available board space constraints.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies in standardized SMD packages. The 402F26022ILR specifically addresses the need for stable 26 MHz timing in space-constrained designs. It shares dimensional characteristics with other parts in the 402 family but differs in electrical parameters based on frequency.

Crystals Replacement Considerations

Direct substitutes include 402F26022ILT, 402F26022IAR, and 402F26022IJR from CTS-Frequency Controls. These variants share identical electrical specifications and physical dimensions. Verify package suffix compatibility for tape-and-reel handling. Parameter-equivalent alternatives may exist from other manufacturers if pinout and electrical values align.
