Crystals Procurement Notes

Verify the specific ordering suffix and revision status before procurement, as engineering samples may differ from mass production specifications. Confirm RoHS compliance documentation and AEC-Q200 qualification if automotive or high-reliability standards are required. Ensure the reel packaging quantity matches your manufacturing line requirements. Cross-reference the datasheet version to avoid using outdated parameter values for final BOM approval.

Crystals Selection Notes

Select this component when a small form factor and wide operating temperature range are critical. The 9 pF load capacitance requires careful matching with external capacitors to account for PCB stray capacitance. Verify that the driving level remains within safe limits for the target MCU's RTC interface. Consider the extended temperature range benefits over standard commercial grade parts for outdoor or industrial deployments.

Crystals Part Context

This part belongs to the AH series of tuning fork crystals from TXC Corporation. These components are specifically engineered for low-power, high-precision timing needs. The series offers various load capacitance options and temperature grades to suit different application constraints. The AH03270004 represents the industrial-grade variant with enhanced thermal stability compared to commercial alternatives.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 9 pF load capacitance, and 3.2x1.5 mm package dimensions. Verify equivalent temperature range and drive level specifications. Check for pin-compatible alternatives from other manufacturers if supply chain constraints exist. Ensure replacement parts meet the same RoHS and reliability standards.
