Substitute Part Grouping Explanation

Substitute parts for the AX5DAF2-491.5200C are determined by strict equivalence across the following critical parameters:

• Frequency: 491.52 MHz (exact match required)
• Output Type: LVDS (signal integrity requirement)
• Supply Voltage: 3.3V (circuit compatibility)
• Function: Enable/Disable (operational requirement)
• Frequency Stability: ±20ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB footprint compatibility)
• Package Dimensions: 5.00mm x 3.20mm (physical fit)
• Maximum Height: 1.50mm (clearance requirement)

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