Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as distributor listings may vary between 100 Ohms and 200 Ohms for similar variants. Confirm the package dimensions match the 2.00mm x 1.60mm footprint required by the PCB layout. Ensure the selected variant meets the -40°C to +85°C operating temperature range for the intended application environment.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency crystal is required for surface-mount assembly. The 18pF load capacitance must align with the oscillator circuit design specifications. Consider the 200 Ohm ESR if the driving circuit requires higher impedance matching compared to lower ESR alternatives. Verify compatibility with the target PCB land pattern for 4-SMD packages.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes for surface-mount applications. The 402F26012IDT specifically provides a 26 MHz output in a small form factor suitable for space-constrained designs. It is distinct from the 416 series which uses different packaging and dimensional specifications.

Crystals Replacement Considerations

The parameter-equivalent substitute part number is 402F26012IDR. Both parts share identical electrical characteristics and package dimensions. Verify that the reel tape configuration of the substitute matches the manufacturing process requirements.
