Crystals Procurement Notes

Verify the specific suffix 'MDAB' against official TXC documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm availability status as lead times may vary based on production schedules and regional distribution channels.

Crystals Selection Notes

Select this component when a compact footprint of 2.0 x 1.6 mm is required for 31.25 MHz applications. Consider the ±30 ppm tolerance limit for circuit design margins. Verify that the 6 pF load capacitance matches the oscillator circuit requirements to ensure accurate frequency operation.

Crystals Part Context

This part belongs to the TXC Corporation 7R series of miniature quartz crystals. The series offers various frequency options in a small SMD package suitable for space-constrained designs. The 7R series is widely used in portable devices and industrial controls where size and reliability are critical factors.

Crystals Replacement Considerations

Cross-reference with other 31.25 MHz crystals from TXC such as the 7R-31.250MAAB-T, ensuring identical package dimensions and electrical parameters. Verify that any substitute maintains the same load capacitance and ESR values to prevent frequency drift.
