Substitute Part Grouping Explanation

Substitution eligibility for the AX7PAF4-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVPECL (signal integrity dependent)
• Supply Voltage: 3.3V (circuit compatibility)
• Function: Enable/Disable capability (operational requirement)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 7.00mm x 5.00mm (footprint constraint)
• Compliance: ROHS3, MSL 1 (regulatory and handling requirements)

The AX7PAF1-1000.0000C meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7PAF4-1000.0000C and AX7PAF1-1000.0000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and supply chain status. Both parts carry identical electrical specifications, package dimensions, and compliance certifications (ROHS3, MSL 1). The AX7PAF1-1000.0000C currently maintains higher inventory levels (909 Pcs vs. 987 Pcs), though both are listed as new original stock. For applications requiring this specific 1 GHz LVPECL oscillator with 3.3V operation and enable/disable functionality, either part provides equivalent performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF1-1000.0000C be used as a direct replacement for the AX7PAF4-1000.0000C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output, supply voltage, package type, and dimensions. No circuit modifications are required.

Q: Are there any differences in pin configuration between these parts?
