Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm the exact temperature range (-20°C to +70°C) and tolerance specifications. Ensure the ordering quantity aligns with standard packaging configurations, such as tape and reel or cut tape options, to match production line requirements. Cross-reference the part number with official distributor catalogs to validate current availability and lead times prior to procurement.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm initial accuracy is required for space-constrained designs. The 4-SMD no-lead package facilitates high-density PCB layouts. Consider the 10 pF load capacitance requirement to ensure compatibility with the host oscillator circuit. Evaluate the -20°C to +70°C operating range against the application's thermal environment to guarantee stable performance under expected conditions.

Crystals Part Context

This part belongs to the 8Z series of high-accuracy MHz crystals from TXC Corporation. The series is characterized by small form factors suitable for portable electronics. The 8Z-40.000MEEQ-T specifically addresses applications needing reliable timing at 40 MHz with moderate stability requirements in consumer and industrial devices.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 10 pF load capacitance and similar ESR values. Verify that alternative parts match the 2.5x2.0 mm footprint and 0.55 mm height constraints. Ensure replacement components meet the same ±10 ppm tolerance and -20°C to +70°C temperature specifications.
