Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF1-600.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 600 MHz (exact match required)
• Output: LVDS (electrical interface compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Function: Enable/Disable (functional feature match)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature: -40°C ~ 85°C (environmental operating range)
• Mounting: Surface Mount, SMD package (PCB assembly compatibility)
• Physical footprint: 7.00mm x 5.00mm (board layout compatibility)

The substitute part 590BB600M000DG from Skyworks Solutions Inc. meets all these critical parameters. Minor variations in package lead count (6-SMD vs. 8-SMD) and maximum supply current do not affect functional substitution when the physical footprint and electrical specifications align.

Engineering Selection Recommendations

The 590BB600M000DG from Skyworks Solutions Inc. is the qualified substitute for the discontinued AX7DAF1-600.0000C. Selection is based on:

• Active product status: The Skyworks part remains in active production, ensuring long-term availability and supply chain continuity.
• Electrical equivalence: All critical electrical parameters (frequency, output type, supply voltage, stability, and operating range) are identical.
• Physical compatibility: Identical footprint dimensions (7.00mm x 5.00mm) and compatible height specifications enable direct PCB layout reuse.
• Compliance alignment: Both parts carry EAR99 classification and meet ROHS3 requirements, maintaining regulatory compliance in existing designs.
• Current consumption: The Skyworks part specifies higher maximum supply current (100mA vs. 70mA), which is compatible with existing power delivery designs.

Frequently Asked Questions (FAQ)

Q: Can the 590BB600M000DG directly replace the AX7DAF1-600.0000C on existing PCBs?

A: Yes. Both parts share identical frequency (600 MHz), output type (LVDS), supply voltage (3.3V), physical footprint (7.00mm x 5.00mm), and operating temperature range (-40°C ~ 85°C). The 6-SMD package of the Skyworks part is compatible with the 8-SMD footprint of the Abracon part for surface mount assembly.

Q: Are there differences in frequency stability between these parts?

A: No. Both parts specify ±25ppm frequency stability, ensuring equivalent timing accuracy for applications requiring this specification.

Q: What is the impact of the higher maximum supply current in the Skyworks part?

A: The 590BB600M000DG specifies 100mA maximum supply current compared to 70mA for the AX7DAF1-600.0000C. This difference does not affect substitution; existing power delivery designs rated for 70mA will operate the Skyworks part within specification. The higher rating provides additional design margin.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.

Q: Are there any compliance or regulatory differences?

A: Both parts carry identical ECCN classification (EAR99) and meet ROHS3 compliance requirements. No regulatory differences exist between the two parts.
