Substitute Part Grouping Explanation

Substitution of the AX5DAF3-491.5200C is determined by strict equivalence across the following critical parameters:

• Frequency: 491.52 MHz (exact match required)
• Output Type: LVDS (signal integrity dependent)
• Supply Voltage: 3.3V (circuit compatibility)
• Function: Enable/Disable capability (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 max (physical fit)
• Current Specifications: 80mA max supply, 70mA max disable (power budget)

The AX5DAF1-491.5200C meets all these criteria and is classified as a parametric equivalent.
