Crystals Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact electrical parameters, as generic model numbers may represent multiple variants. Ensure compatibility with the target PCB land pattern and reflow soldering profile requirements specified in the product documentation.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±15 ppm stability is required. Consider the 9 pF load capacitance requirement for oscillator circuit design. Evaluate the 100 Ohm ESR against the host oscillator's drive level specifications to ensure reliable startup and operation.

Crystals Part Context

This part belongs to the CTS 402 Series, which consists of standard seam-welded surface-mount crystals. The series provides a range of frequencies and packages suitable for general electronic applications requiring stable frequency references in compact form factors.

Crystals Replacement Considerations

Direct substitutes include other 402 series crystals from CTS or equivalent parts from manufacturers like Abracon or Murata with matching 25 MHz frequency, 9 pF load capacitance, and 4-SMD(2x1.6) package dimensions.
