Crystals Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct frequency and tolerance specifications. Confirm that the required load capacitance matches the target circuit design. Check current availability status as components may be discontinued or subject to supply constraints. Ensure compliance with environmental regulations such as RoHS3 for the intended market.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency crystal is required for space-constrained designs. The 8 pF load capacitance must align with the oscillator circuit requirements. Consider the ±10 ppm stability for applications needing tighter frequency control than standard ±15 ppm parts. Verify the 4-SMD footprint compatibility with the PCB layout and reflow soldering profile.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series provides various frequency options in a standardized small outline package. The 402F2701XIKT specifically targets the 27 MHz frequency point within this lineup, offering a balance of size and performance for embedded systems requiring stable clock references.

Crystals Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 8 pF load capacitance, 100 Ohm ESR, and 4-SMD (2x1.6mm) package. Verify that alternative manufacturers offer comparable ±10 ppm stability and similar operating temperature ranges. Cross-reference pinout and electrical characteristics to ensure circuit compatibility without modification.
