Substitute Part Grouping Explanation

Substitute parts for the AX7DBF4-491.5200C are identified based on strict parametric equivalence. The following parameters define substitution eligibility:

• Frequency: 491.52 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (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)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Parts meeting all these criteria are considered direct parametric equivalents and may be substituted without circuit redesign.
