Crystals Procurement Notes

Verify the complete part number including suffixes such as 'T' for tape and reel packaging when ordering. Confirm that the 8pF load capacitance matches the circuit design requirements. Ensure the operating temperature range of -20°C to +70°C aligns with the application environment. Check for RoHS3 compliance if required by project specifications. Validate the 4-SMD footprint dimensions against the PCB layout.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with tight ±10ppm stability. The 8pF load capacitance must match the oscillator circuit's external capacitors. Consider the 80 Ohm ESR value for drive level sensitivity. The compact 1.6x1.2mm package is ideal for dense PCB layouts. Ensure the -20°C to +70°C temperature range covers the operational conditions.

Crystals Part Context

This crystal belongs to the 8Q series from TXC Corporation, which focuses on miniature, high-accuracy MHz quartz crystals. The series offers various frequencies and load capacitances in a standardized 4-SMD no-lead form factor. The 8Q-37.400MEEV-T specifically targets applications requiring precise timing in a small footprint, leveraging TXC's seam seal technology for reliability.

Crystals Replacement Considerations

The 8Q-37.400MAAV-T and 8Q-37.400MEEC-T are listed as similar alternatives by the manufacturer. Verify electrical parameters such as load capacitance and ESR before substitution. The XRCMD37M400F1Q01R0 from Murata Electronics is another potential cross-reference. Ensure mechanical compatibility with the 4-SMD package.
