Crystals Procurement Notes

Verify the specific package variant against official datasheets, as suffixes may indicate dimensional or material differences. Confirm availability through authorized distributors, noting that supply status can fluctuate. Ensure the ordering information matches the required load capacitance and frequency tolerance for your specific circuit design requirements.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm stability is required in a compact 3.2x2.5 mm footprint. Consider the -20°C to +70°C operating range for commercial applications. Verify compatibility with the target oscillator circuit's load capacitance requirements, specifically the 20 pF specification, to ensure accurate frequency performance.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series offers various standard frequencies in a small surface-mount package. The 7M-40.000MEIK-T specifically addresses timing needs for digital systems requiring moderate stability in a cost-effective form factor suitable for high-volume manufacturing.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 3.2x2.5 mm dimensions, ±10 ppm tolerance, and 20 pF load capacitance. Cross-reference with similar TXC models like 7M-40.000MEEQ-T, ensuring temperature ranges and ESR values match application constraints.
