Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0747500044 is based on alignment with the following critical parameters:

Manufacturer Consistency: Both the main part and substitute are manufactured by Molex, ensuring design philosophy and quality standards remain consistent.

Base Product Family: The substitute part shares the same base product number (074750), indicating it belongs to the same product family and design lineage.

Functional Category: Both parts are classified as pluggable connectors within the QSFP PCI heat sink cage assembly category, maintaining functional equivalence for system integration.

Connector Architecture: The substitute part is specified as a QSFP+ cage with heat sink connector, providing the same thermal management and signal integrity features required for high-speed interconnect applications.

Mounting and Termination: The substitute employs press-fit through-hole mounting with right-angle orientation, supporting standard PCB assembly processes compatible with the original design.

Compliance Standards: The substitute maintains RoHS compliance and is assigned ECCN classification EAR99, supporting regulatory requirements for commercial distribution.

The primary distinction between the main part and substitute is the active product status of the substitute (0747503044), which ensures ongoing manufacturer support, availability, and technical documentation.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The Molex 0747503044 is the manufacturer-recommended substitute for the obsolete 0747500044. Selection of the active substitute part ensures access to current manufacturing processes, quality assurance protocols, and technical support from Molex.

For New Designs: The 0747503044 should be specified in new designs to avoid future obsolescence issues and to benefit from the active product status, which guarantees continued availability and compatibility with current manufacturing standards.

For Maintenance and Repair: When replacing failed units in existing systems, the 0747503044 provides functional equivalence while supporting long-term system reliability through manufacturer backing and documented specifications.

Compliance Considerations: Both parts maintain RoHS compliance. The substitute part carries ECCN classification EAR99, which is suitable for commercial distribution channels and does not impose additional export restrictions beyond standard commercial regulations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0747503044 be used as a direct replacement for the 0747500044 in existing assemblies?

A: Yes. Both parts share the same base product number (074750), belong to the same QSFP PCI heat sink cage assembly category, and are manufactured by Molex. The substitute part is the manufacturer-recommended equivalent for the obsolete model.

Q: What is the primary reason for substituting the 0747500044?

A: The 0747500044 carries obsolete product status, indicating it is no longer manufactured or supported by Molex. The 0747503044 is an active product that provides the same functional capability with ongoing manufacturer support.

Q: Are there any differences in mounting or installation between these parts?

A: The substitute part (0747503044) is specified with through-hole, right-angle mounting and press-fit termination. These specifications should be verified against the original assembly design to ensure compatibility with existing PCB layouts and assembly processes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are RoHS compliant. The substitute part carries ECCN classification EAR99, which supports standard commercial distribution. Moisture sensitivity levels differ, with the main part rated MSL 1 (Unlimited) and the substitute rated as Not Applicable.

Q: What inventory considerations should be evaluated when transitioning from the obsolete to the active part?

A: The obsolete part (0747500044) has 759 units currently in stock, while the substitute (0747503044) has 1150 units available. For long-term supply chain planning, the active substitute part provides greater assurance of continued availability through standard distribution channels.

Q: Are there any electrical or mechanical parameter differences that would affect system performance?

A: Substitution is based on functional equivalence within the QSFP PCI heat sink cage assembly category. Both parts are designed to support the same connector architecture and thermal management requirements. Specific electrical and mechanical parameters not provided in the available documentation should be verified through Molex technical datasheets.
