Crystals Procurement Notes

Verify the specific suffix 'B' against official Epson documentation to confirm exact electrical tolerances and packaging details. Ensure compatibility with existing PCB footprint and reflow soldering profiles. Cross-reference part numbers to distinguish between similar variants such as AC3 or AC0 which may have different load capacitances or stability ratings.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm stability is required. Confirm that the 16 pF load capacitance matches the oscillator circuit design. Verify that the 40 Ohm ESR limit is compatible with the host system's drive level requirements. Check thermal specifications against the intended operational environment.

Crystals Part Context

This part belongs to the FA-20H series of crystals from Epson Timing. The series is characterized by small form factors and stable performance. Variants within the series differ primarily in frequency, stability, and load capacitance parameters defined by their ordering suffixes.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 16 pF load capacitance, and 4-SMD 2.5x2mm package. Verify ESR limits and temperature range compatibility. Consult manufacturer cross-reference lists for approved alternatives.
