Substitute Part Grouping Explanation

Substitution of the AX7MCF2-50.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output Type: CML (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Footprint Dimensions: 7.00mm x 5.00mm (exact match required)

The substitute part 590WB50M0000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. While the package configuration differs (6-SMD vs. 8-SMD), both maintain identical footprint dimensions and height specifications compatible with the original PCB layout.

Engineering Selection Recommendations

The 590WB50M0000DG from Skyworks Solutions Inc. is a direct functional substitute for the discontinued AX7MCF2-50.0000C. Selection is based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters align exactly—frequency, output type, supply voltage, function, frequency stability, and operating temperature range are identical between the two components.

Mechanical Compatibility: Both components share identical footprint dimensions (7.00mm x 5.00mm) and are surface-mount packages with no-lead configurations. The 590WB50M0000DG has a slightly lower seated height (1.80mm vs. 1.90mm), which presents no compatibility issues for standard PCB layouts.

Power Consumption: The 590WB50M0000DG exhibits higher maximum supply current (110mA vs. 68mA) and higher disable-mode current (75mA vs. 67mA). Power budget analysis is required to confirm system-level compatibility.

Product Status: The 590WB50M0000DG is active and in production, ensuring long-term availability and supply chain continuity compared to the discontinued Abracon part.

Compliance: The original AX7MCF2-50.0000C is ROHS3 compliant. Compliance status for the Skyworks substitute should be verified during procurement.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG be used as a direct replacement on existing PCBs designed for the AX7MCF2-50.0000C?

A: Yes. Both components have identical footprint dimensions (7.00mm x 5.00mm) and are surface-mount, no-lead packages. The 590WB50M0000DG has a lower seated height (1.80mm vs. 1.90mm), which is compatible with standard PCB layouts. However, verify that the 6-SMD pad configuration of the Skyworks part aligns with your PCB design before production implementation.

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

A: The package configuration refers to the number of solder pads on the component. While the AX7MCF2-50.0000C uses 8 pads and the 590WB50M0000DG uses 6 pads, both maintain the same external footprint dimensions and are compatible with identically sized PCB landing patterns. The internal pad arrangement differs, but electrical function remains equivalent.

Q: Are there any power consumption differences I should account for?

A: Yes. The 590WB50M0000DG has higher maximum supply current (110mA vs. 68mA) and higher disable-mode current (75mA vs. 67mA). Verify that your system's power supply and current budgeting can accommodate these higher values before implementation.

Q: Is the 590WB50M0000DG RoHS compliant?

A: RoHS compliance status for the 590WB50M0000DG is not specified in the available data. Confirm compliance requirements with your procurement team and request compliance documentation from Skyworks Solutions Inc. if RoHS certification is mandatory for your application.

Q: What is the frequency stability tolerance, and does it affect system performance?

A: Both components have identical frequency stability of ±25ppm across the operating temperature range of -40°C to 85°C. This specification is unchanged between the original and substitute part, ensuring equivalent timing accuracy for your application.
