Substitute Part Grouping Explanation

The AX5DBF1-300.0000C qualifies as a parametric equivalent to the AX5DBF3-300.0000C based on the following critical substitution parameters:

• Frequency: Both parts operate at 300 MHz
• Output Configuration: Both provide LVDS output
• Supply Voltage: Both require 2.5V operation
• Enable/Disable Function: Both include this control feature
• Frequency Stability: Both maintain ±20ppm stability
• Operating Temperature Range: Both support -40°C ~ 85°C
• Supply Current Specifications: Both draw maximum 80mA during operation and 70mA in disable mode
• Package Type: Both use 8-SMD, No Lead housing
• Physical Dimensions: Both share identical package footprint (5.00mm x 3.20mm x 1.50mm max height)
• Compliance Standards: Both are ROHS3 compliant with MSL 1 rating

The substitution is based on electrical and mechanical parameter equivalence within the ClearClock™ AX5 oscillator family.
