Crystals Procurement Notes

Verify the specific suffix 'IAT' against the manufacturer's official datasheet to confirm tape and reel packaging and exact electrical tolerances. Ensure the load capacitance requirement matches the target circuit design before procurement. Cross-reference the full part number with authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when a 27 MHz fundamental crystal with 10 pF load capacitance is required. The 4-SMD package suits automated assembly processes. Verify that the operating temperature range and stability requirements align with the application environment. Confirm compatibility with the host oscillator circuit impedance.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series offers various frequencies and load capacitances in standardized packages. The 402F27012IAT specifically addresses needs for 27 MHz timing in space-constrained designs. It complements other variants in the family differing only in frequency or capacitance values.

Crystals Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 10 pF load capacitance, 100 Ohm ESR, and 4-SMD 2.00x1.60mm footprint. Verify pinout compatibility and mounting dimensions. Check if alternative manufacturers offer RoHS3 compliant equivalents with identical electrical parameters.
