Substitute Part Grouping Explanation

The AX7DBF1-400.0000C qualifies as a parametric equivalent to the AX7DBF4-400.0000C based on the following critical substitution parameters:

• Identical frequency specification: 400 MHz
• Identical output type: LVDS
• Identical supply voltage: 2.5V
• Identical enable/disable function
• Identical frequency stability: ±25ppm
• Identical operating temperature range: -40°C ~ 85°C
• Identical maximum supply current: 70mA
• Identical package type and dimensions: 8-SMD, No Lead (7.00mm x 5.00mm x 1.90mm)
• Identical RoHS and REACH compliance status
• Same manufacturer: Abracon LLC

Both parts belong to the ClearClock™ AX7 series and share identical electrical and mechanical specifications, making them direct substitutes for circuit design and PCB layout purposes.
