Crystals Procurement Notes

Verify that the specific part number matches the required automotive qualification standards. Confirm the load capacitance and frequency tolerance align with the target circuit design specifications before procurement. Ensure supply chain sources provide valid traceability documentation for AEC-Q200 compliance.

Crystals Selection Notes

Select this component when automotive-grade durability and compact size are critical. The 8 pF load capacitance requires matching with the host system's external capacitors. Consider the wide operating temperature range for harsh environment deployments.

Crystals Part Context

This model belongs to TXC's automotive quartz crystal series, distinguished by its small form factor and robust sealing. It serves as a precise clock source for microcontrollers and communication modules in vehicles where space constraints and thermal resilience are paramount.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 8 pF load capacitance, and 2.0x1.6 mm package. Verify AEC-Q200 certification if automotive use is required. Cross-reference pinout and electrical characteristics for compatibility.
