Substitute Part Grouping Explanation

Substitution of the AX7MCF3-50.0000C 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 (exact match required)
Frequency Stability: ±25ppm (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Package Dimensions: 7.00mm x 5.00mm (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The 590WB50M0000DG from Skyworks Solutions Inc. meets all critical substitution criteria. While the package configuration differs (6-SMD vs. 8-SMD, No Lead), the footprint dimensions remain identical at 7.00mm x 5.00mm, and the maximum seated height is within acceptable tolerance (1.80mm vs. 1.90mm). All electrical parameters, compliance certifications, and functional specifications align with the original component.

Engineering Selection Recommendations

The 590WB50M0000DG is a direct functional substitute for the AX7MCF3-50.0000C. Both components are ROHS3 compliant and carry identical Moisture Sensitivity Level ratings. The Skyworks component is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

Supply current specifications differ between the two components. The 590WB50M0000DG draws a maximum of 110mA compared to 68mA for the original part, representing a 42mA increase during normal operation. Power budget analysis is required to confirm system-level compatibility.

Package configuration differs (6-SMD vs. 8-SMD), though footprint dimensions and maximum height remain compatible. PCB layout verification is necessary to confirm pad alignment and thermal performance.

Both components share identical electrical specifications, frequency stability, operating temperature range, and functional characteristics. The substitute part maintains full compatibility with 1.8V supply systems requiring 50 MHz CML output with Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG be used as a direct replacement for the AX7MCF3-50.0000C?

A: Yes, the 590WB50M0000DG meets all critical electrical and functional specifications. However, the package configuration differs (6-SMD vs. 8-SMD), requiring PCB layout verification before implementation.

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

A: The 590WB50M0000DG draws 110mA maximum compared to 68mA for the original part. System power budget analysis is required to confirm that power delivery and thermal management remain within design specifications.

Q: Are the package dimensions compatible?

A: Yes. Both components share identical footprint dimensions of 7.00mm x 5.00mm. The maximum seated height of the Skyworks component (1.80mm) is lower than the original (1.90mm), providing additional clearance margin.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Is the Skyworks component currently available?

A: Yes. The 590WB50M0000DG is in active production status, ensuring ongoing availability and supply chain support.

Q: Do both components support Enable/Disable functionality?

A: Yes. Both the AX7MCF3-50.0000C and 590WB50M0000DG provide Enable/Disable control at 1.8V supply voltage.
