Crystals Procurement Notes

Verify the specific suffix 'AAQ' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the PCB footprint aligns with the 2.0x1.6 mm dimensions. Confirm that the 10 pF load capacitance requirement is compatible with your host circuit's design specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 31.25 MHz output suits applications needing precise timing without the complexity of active oscillators. Consider the 10 pF load capacitance requirement during schematic design. Evaluate the -20°C to +70°C temperature range against your operational environment constraints to ensure long-term reliability.

Crystals Part Context

This part belongs to the 7R series of MHz crystals from TXC Corporation. The series specializes in glass-sealed quartz crystals designed for general-purpose electronic applications. These components are engineered to provide stable frequency references in space-constrained designs while maintaining cost-effectiveness for high-volume production environments.

Crystals Replacement Considerations

Cross-reference with other 7R series variants such as 7R-31.250MAAJ-T if different load capacitance or tolerance levels are acceptable. Verify package compatibility when substituting with similar-sized crystals from other manufacturers.
