Substitute Part Grouping Explanation

Substitution eligibility for the AX5PBF2-1800.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1.8 GHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Maximum Supply Current: 110mA (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The AX5PBF1-1800.0000C meets all substitution criteria as a parametric equivalent within the same ClearClock™ AX5 series.
