Substitute Part Grouping Explanation

The 590FB500M000DG (Skyworks Solutions Inc., Si590 series) qualifies as a manufacturer-recommended substitute for the AX7DBF2-500.0000C based on the following critical parameters:

Matching Parameters:

• Frequency: 500 MHz
• Output Type: LVDS
• Supply Voltage: 2.5V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Footprint Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS Code: 8542.39.0001

Package Difference: The substitute uses a 6-SMD, No Lead package versus the original 8-SMD, No Lead package. Both packages maintain identical footprint dimensions and seated height compatibility within acceptable tolerances (original: 0.075" max, substitute: 0.071" max).

Parameter Comparison

Engineering Selection Recommendations

The 590FB500M000DG is the manufacturer-recommended substitute for the discontinued AX7DBF2-500.0000C. Both components maintain identical electrical specifications for frequency, output type, supply voltage, function, and frequency stability. The footprint dimensions are identical, ensuring PCB layout compatibility without redesign.

The substitute operates at higher maximum supply currents (100mA vs. 70mA) and disable current (75mA vs. 65mA), which represents increased power consumption but does not affect functional compatibility in applications designed for the original part's specifications. The substitute's slightly lower seated height (0.071" vs. 0.075") provides additional clearance margin in space-constrained assemblies.

Both components maintain equivalent compliance status: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. The substitute's active product status ensures long-term availability and supply chain continuity compared to the discontinued original.

Frequently Asked Questions (FAQ)

Q: Can the 590FB500M000DG be used as a direct replacement for the AX7DBF2-500.0000C?

A: Yes. Both components share identical frequency (500 MHz), output type (LVDS), supply voltage (2.5V), function (Enable/Disable), frequency stability (±25ppm), and operating temperature range (-40°C ~ 85°C). Footprint dimensions are identical, enabling direct PCB substitution without layout modification.

Q: What is the difference between the 8-SMD and 6-SMD packages?

A: The package designation refers to the number of solder pads. Both packages maintain the same footprint dimensions (7.00mm x 5.00mm) and are mechanically compatible on the PCB. The internal lead configuration differs, but this does not affect electrical performance or pinout compatibility for this application.

Q: Are there any power consumption differences between the original and substitute?

A: The substitute operates at higher maximum supply currents: 100mA (vs. 70mA original) and 75mA disable current (vs. 65mA original). Applications must verify that power supply capacity accommodates the substitute's higher current draw. This difference does not affect functional compatibility.

Q: Is the substitute suitable for the same temperature range?

A: Yes. Both components operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in equivalent operating environments.

Q: What is the significance of the identical ECCN and HTSUS codes?

A: Both components share the same export control classification (EAR99) and tariff code (8542.39.0001), indicating equivalent regulatory and trade compliance status. No additional export or import documentation changes are required when substituting between these parts.
