Crystals Procurement Notes

Verify the manufacturer designation carefully as the model number appears associated with multiple entities including TXC Corporation in some catalogs. Confirm the specific package dimensions and load capacitance requirements against your schematic before ordering. Ensure the supplier provides documentation confirming the -20°C to 70°C operating range. Cross-reference the part number with official distributor listings to avoid confusion with similar variants or tone squelch units sharing the FTS prefix.

Crystals Selection Notes

Select this component when a 18.432 MHz fundamental frequency is required in a small surface-mount footprint. The 20 pF load capacitance must match the oscillator circuit design specifications. Consider the -20°C to 70°C temperature range suitability for the intended environment. Verify that the 5.0 x 3.2 mm package fits within the available PCB area constraints compared to larger through-hole alternatives.

Crystals Part Context

This crystal belongs to the category of passive frequency control components used for timing stability. It serves as a critical element in oscillators where accurate timekeeping or data synchronization is necessary. The surface-mount format allows for reduced board space usage compared to traditional leaded packages. These components are standard in telecommunications and datacom equipment requiring reliable clock sources.

Crystals Replacement Considerations

Equivalent parts include the TXC 7A-18.432MBBK-T which shares identical electrical characteristics and physical dimensions. Other surface-mount crystals offering 18.432 MHz frequency and 20 pF load capacitance may serve as substitutes if pin compatibility and thermal ratings align with the original design requirements.
