Substitute Part Grouping Explanation

Substitute parts for the AX7DBF2-156.2500C are determined by strict equivalence across the following critical parameters:

• Frequency: 156.25 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)
• Maximum Supply Current: 70mA (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute parts AX7DBF1-156.2500C and AX7DBF3-156.2500C meet all these criteria and are therefore direct parametric equivalents within the ClearClock™ AX7 series.
