Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7MCF1-50.0000C is determined by 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)
• Package Footprint: 7.00mm x 5.00mm (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The 590WB50M0000DG from Skyworks Solutions Inc. meets all critical substitution criteria. While the package configuration differs (6-SMD vs. 8-SMD), the physical footprint dimensions and mounting characteristics remain compatible for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

The 590WB50M0000DG qualifies as a direct functional substitute for the AX7MCF1-50.0000C based on electrical and mechanical parameter alignment. The substitute part is currently active in production, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

• Electrical Compatibility: All critical electrical parameters (frequency, output type, supply voltage, stability, and temperature range) are identical between the main part and substitute.
• Physical Compatibility: Both components share identical footprint dimensions (7.00mm x 5.00mm) and compatible seated heights, supporting direct board-level replacement.
• Compliance Status: The substitute part maintains ROHS3 compliance and MSL 1 rating, matching the original component's environmental and regulatory requirements.
• Supply Current: The substitute exhibits higher maximum supply current (110mA vs. 68mA). Power budget analysis is required to confirm system-level compatibility.
• Product Status: The substitute is active and in stock, providing immediate procurement availability compared to the discontinued original part.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG be used as a direct replacement for the AX7MCF1-50.0000C?

A: Yes. Both components share identical electrical specifications (50 MHz, CML output, 1.8V supply, ±25ppm stability, -40°C to 85°C operating range) and compatible physical footprints (7.00mm x 5.00mm). The substitute is suitable for direct board-level replacement provided power supply capacity accommodates the higher current draw.

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

A: The package configuration refers to the internal lead count and pinout arrangement. Both configurations maintain the same external footprint dimensions and mounting characteristics. Pin-to-pin compatibility must be verified against the specific application schematic to ensure proper signal routing and functionality.

Q: Does the higher supply current of the 590WB50M0000DG affect system design?

A: The substitute draws a maximum of 110mA compared to 68mA for the original part. System power supply and current distribution design must accommodate this difference. Verify that power delivery networks and supply rails are rated for the higher current requirement.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX7MCF1-50.0000C and 590WB50M0000DG are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent environmental and regulatory standards.

Q: What is the availability status of each part?

A: The AX7MCF1-50.0000C is discontinued at DiGi Electronics. The 590WB50M0000DG is active in production with 860 units in stock, providing reliable procurement availability for new designs and system support.
