Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF2-50.0000C is determined by the following critical parameters:

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

The 590WB50M0000DG from Skyworks Solutions Inc. meets all critical substitution criteria. While the supply voltage differs (1.8V vs. 2.5V) and the package configuration varies (6-SMD vs. 8-SMD), the identical frequency, output type, function, temperature range, frequency stability, and footprint dimensions establish this part as a functional equivalent for applications where the lower supply voltage is compatible with system design.

Parameter Comparison

Engineering Selection Recommendations

The 590WB50M0000DG is an active product from Skyworks Solutions Inc., ensuring ongoing availability and supply chain continuity compared to the discontinued AX7MBF2-50.0000C. Both parts maintain identical frequency stability (±25ppm), operating temperature range (-40°C to 85°C), and footprint dimensions (7.00mm x 5.00mm), supporting direct PCB layout compatibility.

The primary design consideration is the supply voltage difference: the substitute operates at 1.8V versus the original 2.5V. System designs with 1.8V supply rails or voltage regulation capable of supporting 1.8V operation can directly implement the 590WB50M0000DG. The substitute's maximum supply current of 110mA exceeds the original specification of 68mA; power budget verification is required for applications with constrained current delivery.

Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG replace the AX7MBF2-50.0000C in all applications?

A: Substitution is valid for applications where the system supply voltage is 1.8V or where voltage regulation can provide 1.8V to the oscillator. The identical frequency (50 MHz), output type (CML), function (Enable/Disable), and footprint dimensions (7.00mm x 5.00mm) ensure functional compatibility in these scenarios. Applications requiring 2.5V supply operation require alternative solutions.

Q: What is the impact of the different package configurations (8-SMD vs. 6-SMD)?

A: Both parts share identical footprint dimensions (7.00mm x 5.00mm), allowing PCB layout reuse. The difference in SMD lead count (8 vs. 6) reflects internal design variations between manufacturers but does not affect board-level compatibility when footprint dimensions match.

Q: Are there compliance differences between the two parts?

A: The AX7MBF2-50.0000C is explicitly ROHS3 Compliant. The 590WB50M0000DG RoHS status is not specified in the provided data. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) and ECCN EAR99 classification.

Q: How does the higher supply current of the substitute affect system design?

A: The 590WB50M0000DG maximum supply current is 110mA compared to 68mA for the original part. System power delivery and current budgeting must accommodate this higher specification. Disable mode current is 75mA versus 67mA for the original, representing a 12% increase in idle power consumption.

Q: Is the frequency stability identical between both parts?

A: Yes, both parts specify ±25ppm frequency stability across the -40°C to 85°C operating temperature range, ensuring equivalent timing performance.
