Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7PAF4-300.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 300 MHz
• Output Type: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Current - Supply (Max): 94mA

The AX7PAF3-300.0000C meets all these parameters and is classified as a parametric equivalent. Both parts share identical electrical specifications, thermal performance, and mechanical form factor, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations
