Substitute Part Grouping Explanation

Substitute parts for the AX7DBF2-491.5200C are identified based on strict electrical and mechanical parameter matching within the ClearClock™ AX7 series. The critical parameters determining substitution eligibility are:

• Frequency: 491.52 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package: 8-SMD, No Lead (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

Parts meeting all these parameters are classified as parametric equivalents and may be used interchangeably in applications designed for the AX7DBF2-491.5200C.
