Crystals Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is limited to existing stock or third-party distributors. Verify part authenticity and storage conditions carefully when sourcing from secondary markets. Ensure compatibility with existing designs before procurement due to end-of-life status.

Crystals Selection Notes

Select this component only if the specific 40MHz frequency and 20pF load capacitance match the circuit requirements. Consider the ±30ppm stability limit against system timing needs. Evaluate the -20°C to +70°C temperature range against environmental conditions. Due to obsolescence, assess long-term supply chain risks and potential redesign implications.

Crystals Part Context

The 7A series represents TXC Corporation's line of miniature surface-mount crystals. This specific model utilizes standard AT-cut quartz technology for reliable oscillation. It belongs to a family of components offering various frequencies and packages, though this particular variant has reached its end-of-life stage.

Crystals Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should consult TXC Corporation for current equivalent series or consider alternative manufacturers offering similar 40MHz SMD crystals with compatible electrical parameters.
