Crystals Procurement Notes

Verify the specific suffix codes against the official TXC datasheet to confirm exact electrical tolerances and temperature ranges. Ensure the ordering part number matches the required AEC-Q200 certification level. Confirm package dimensions and pin configuration align with the target PCB layout. Check for any recent updates to the RoHS or REACH compliance status prior to final procurement.

Crystals Selection Notes

Select this component when high-frequency stability is critical for automotive clocking applications. The ±30ppm stability ensures consistent performance under varying thermal conditions typical in vehicle interiors. The seam seal technology offers superior protection against moisture and contaminants compared to standard epoxy-sealed crystals. Consider the 2.5x2.0mm footprint for space-constrained designs requiring robust mechanical integrity.

Crystals Part Context

This part belongs to TXC's line of high-accuracy MHz quartz crystals tailored for demanding industrial and automotive sectors. The AZ series specifically targets applications requiring rigorous quality certifications and long-term reliability. It complements other TXC oscillator and resonator products by providing a discrete solution for custom circuit designs where integrated oscillators are not suitable.

Crystals Replacement Considerations

Direct substitutes include the 8Q-37.400MEEV-T and 8Q-37.400MAAV-T from TXC Corporation, which share similar frequency and package characteristics. Verify that alternative parts meet the same AEC-Q200 automotive qualification standards and temperature range specifications before implementation.
