Substitute Part Grouping Explanation

Substitution of the AX7DBF3-400.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 400 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Maximum Supply Current: 70mA (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The AX7DBF1-400.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-400.0000C is a direct parametric equivalent to the AX7DBF3-400.0000C. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part maintains identical electrical specifications, frequency stability, operating temperature range, and current consumption characteristics. Both parts are discontinued at DiGi Electronics; however, the AX7DBF1-400.0000C currently has higher inventory availability (913 Pcs vs. 819 Pcs). Selection between these parts should be based on procurement availability and lead time requirements, as all functional and compliance parameters are equivalent.
