Substitute Part Grouping Explanation

Substitution of the AX7DCF4-1800.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1.8 GHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm x 1.90mm max (exact match required)
• Enable/Disable Function: Present (exact match required)

The AX7DCF1-1800.0000C meets all substitution criteria as a parametric equivalent within the Abracon ClearClock™ AX7 series.
