Crystals Procurement Notes

Verify the specific manufacturer designation as sources list both FTS and TXC Corporation for this part number. Confirm the exact frequency tolerance specification, as documentation varies between ±30ppm and ±50ppm. Ensure the selected variant matches the required ESR and load capacitance parameters for the target circuit design before finalizing procurement.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required in a compact surface-mount form factor. Verify that the 40 Ohm ESR aligns with the oscillator circuit requirements. Consider the -20°C to +70°C temperature range suitability for the intended operational environment and ensure the 18 pF load capacitance matches the host device specifications.

Crystals Part Context

This component belongs to the 7B series of surface-mount crystals manufactured by FTS. It serves as a precision timing element for electronic circuits requiring stable frequency references. The series is characterized by its small physical footprint and compatibility with standard reflow soldering processes used in modern electronics manufacturing.

Crystals Replacement Considerations

The 9B-14.31818MBBK-B is a through-hole alternative from TXC Corporation with similar electrical characteristics but different mounting requirements. Cross-reference the pinout and mechanical dimensions carefully when substituting components to ensure board layout compatibility.
