Substitute Part Grouping Explanation

Substitution of the AX7DAF2-600.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 600 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Function: Enable/Disable (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package Footprint: 7.00mm x 5.00mm (exact match required)

The substitute part 590BB600M000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. Variations in package lead count (8-SMD vs. 6-SMD) and maximum supply current do not preclude substitution when the footprint dimensions and electrical specifications align.

Engineering Selection Recommendations

The 590BB600M000DG from Skyworks Solutions Inc. is the qualified substitute for the discontinued AX7DAF2-600.0000C. Selection is based on the following engineering criteria:

• All critical electrical parameters (frequency, output type, supply voltage, frequency stability, operating temperature range, and function) are identical.
• The package footprint dimensions (7.00mm x 5.00mm) are identical, ensuring PCB layout compatibility.
• The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.
• Both parts maintain equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification.
• The substitute part's maximum supply current (100mA) and disable current (75mA) exceed the original part specifications, providing design margin.
• The substitute part's seated height (1.80mm) is lower than the original (1.90mm), presenting no clearance concerns.

Frequently Asked Questions (FAQ)

Q: Can the 590BB600M000DG be used as a direct replacement for the AX7DAF2-600.0000C?

A: Yes. Both parts share identical frequency (600 MHz), output type (LVDS), supply voltage (3.3V), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package footprint (7.00mm x 5.00mm). The substitute part is electrically and mechanically compatible for PCB integration.

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

A: The package lead count differs, but both maintain the same footprint dimensions (7.00mm x 5.00mm) and height compatibility. The 6-SMD configuration of the substitute part is lower in profile (1.80mm vs. 1.90mm), which does not create clearance issues in standard applications.

Q: Are there compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity levels are identical (MSL 1, Unlimited).

Q: Does the higher maximum supply current of the substitute part affect circuit design?

A: No. The substitute part's maximum supply current (100mA) and disable current (75mA) are higher than the original specifications (70mA and 65mA respectively). This provides additional design margin and does not require circuit modifications.

Q: What is the availability status of the substitute part?

A: The 590BB600M000DG is in active production status with current inventory of 845 pieces available. The original AX7DAF2-600.0000C is discontinued at DiGi Electronics, making the substitute the recommended solution for new designs and ongoing procurement.
