Substitute Part Grouping Explanation

Substitution for the AX5PBF3-1800.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1.8 GHz (exact match required)
• Output Type: LVPECL (signal integrity dependent)
• Supply Voltage: 2.5V (circuit compatibility)
• Function: Enable/Disable (operational requirement)
• Frequency Stability: ±20ppm (timing tolerance)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 5.00mm x 3.20mm x 1.50mm maximum height (physical fit)

The substitute part AX5PBF1-1800.0000C meets all these parameters identically, establishing it as a direct parametric equivalent within the ClearClock™ AX5 series.
