Key Parameters

Substitute Part Grouping Explanation

Substitution of the VSC7391XHO is determined by the following critical parameters:

• Manufacturer Alignment: Both the main part and substitute are manufactured by Microchip Technology, ensuring design consistency and support continuity.
• Functional Category: Both components operate within the Interface category, specifically as Ethernet switch ICs.
• Compliance Standards: Both parts maintain ROHS3 compliance, meeting environmental and regulatory requirements.
• Product Family: The VSC7427XJG-02 belongs to the SparX™-III-26 series, representing an active, supported product line from the same manufacturer.

The VSC7427XJG-02 is designated as the manufacturer-recommended substitute and is currently in Active product status, providing long-term availability and ongoing technical support.

Parameter Comparison

Engineering Selection Recommendations

The VSC7391XHO is obsolete and no longer supported by the manufacturer. The VSC7427XJG-02 is the manufacturer-recommended substitute and maintains Active product status, ensuring continued availability, technical documentation, and design support.

Both components are ROHS3 compliant and manufactured by Microchip Technology. The VSC7427XJG-02 features a higher MSL rating (4 vs. 1), which may require adjusted handling procedures during assembly but does not affect electrical performance or functional compatibility within the Interface IC category.

Selection of the VSC7427XJG-02 is appropriate for new designs and systems requiring long-term component availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the VSC7427XJG-02 directly replace the VSC7391XHO in existing designs?

A: Both components are Microchip Technology Interface ICs with ROHS3 compliance and Surface Mount packaging. Electrical and functional compatibility must be verified against your specific application requirements and PCB design specifications.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The VSC7391XHO has MSL 1 (Unlimited shelf life), while the VSC7427XJG-02 has MSL 4 (72-hour floor life after moisture exposure). MSL 4 components require stricter moisture control during storage and assembly but do not affect electrical performance.

Q: Why is the VSC7391XHO marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The VSC7427XJG-02, as an Active product in the SparX™-III-26 series, represents the current supported alternative.

Q: Are both parts available in inventory?

A: Yes. The VSC7391XHO has 1392 units in stock, and the VSC7427XJG-02 has 2010 units in stock as new original components.

Q: What packaging format is used for the VSC7427XJG-02?

A: The VSC7427XJG-02 is supplied in Tray packaging in a 672-HSBGA (27x27) configuration.
