Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MCF4-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz
• Output Type: CML
• Supply Voltage: 1.8V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Current - Supply (Max): 68mA
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height - Seated (Max): 0.075" (1.90mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.
