Crystals Procurement Notes

Verify the specific suffix and packaging configuration against the official datasheet before ordering. Confirm that the AEC-Q200 certification status aligns with your project's quality requirements. Ensure the 3.2mm x 2.5mm package dimensions are compatible with your PCB layout constraints. Cross-reference the manufacturer part number directly with TXC Corporation documentation to avoid substitution errors.

Crystals Selection Notes

Select this component when a 42 MHz reference is required in space-constrained automotive designs. The 8 pF load capacitance must match the oscillator circuit design specifications. Consider the ±30 ppm stability requirement relative to system timing tolerance. The glass seal technology offers superior performance compared to standard ceramic packages in harsh thermal conditions.

Crystals Part Context

This part belongs to the AV/AA series of automotive-grade crystals from TXC Corporation. These components are engineered specifically for the demanding temperature ranges and vibration profiles found in modern vehicles. The series emphasizes long-term frequency stability and robust mechanical integrity under automotive stress conditions.

Crystals Replacement Considerations

Direct substitutes include other AEC-Q200 qualified 42 MHz crystals in the same package size. Verify ESR and load capacitance compatibility before swapping manufacturers. Ensure the replacement maintains the same glass seal construction if environmental sealing is critical.
