Crystals Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation, as component availability may fluctuate. Ensure that the receiving facility's handling procedures align with the Moisture Sensitivity Level (MSL) rating of 1 to prevent damage during storage and reflow soldering. Confirm that the final assembly environment meets the specified operating temperature range requirements for reliable long-term performance.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency with ±30 ppm stability is required for space-constrained designs. The 4-SMD package offers a balance between thermal performance and board real estate efficiency compared to larger through-hole alternatives. Consider the 40 Ohm ESR value to ensure compatibility with the oscillator circuit's drive level constraints and impedance matching requirements.

Crystals Part Context

This part belongs to the TXC Corporation quartz crystal family, specifically engineered for general-purpose timing applications. It utilizes standard AT-cut quartz technology to achieve the specified frequency stability over the industrial temperature range. The component serves as a passive frequency-determining element within active oscillator circuits or direct clock inputs.

Crystals Replacement Considerations

The 7V-19.200MAAJ-T is listed as a similar alternative from the same manufacturer. Verify package dimensions and electrical parameters before substitution. Cross-manufacturer replacements require rigorous validation of footprint compatibility and frequency tolerance specifications.
