Connector Type: Both parts are QSFP+ connectors, maintaining compatibility with standard QSFP+ transceiver modules and host interfaces.

Base Product Number: Both parts share the base product number 074750, indicating they are part of the same connector platform and design generation.

Environmental Compliance: The substitute part maintains RoHS compliance and carries an active product status, ensuring continued availability and regulatory alignment.

Functional Category: Both parts function as position connectors within the QSFP+ cage assembly category, supporting equivalent electrical and mechanical performance requirements.

The Molex 0747503586 is identified as the manufacturer-recommended substitute, offering active product status and current production support.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The Molex 0747503586 is the manufacturer-recommended substitute for the obsolete 0747501586. Both parts maintain the same base product number (074750) and QSFP+ connector type, ensuring compatibility within the Molex 74750 series platform.

Product Status Consideration: The 0747501586 is classified as obsolete and no longer supported by the manufacturer. The 0747503586 carries active product status, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Compliance and Certification: Both parts are RoHS compliant. The substitute part carries an EAR99 ECCN classification, indicating standard commercial export status. The main part's ECCN is listed as obsolete, reflecting its discontinued status.

Inventory and Supply Chain: The substitute part (0747503586) has 888 pieces in current stock, providing immediate availability. The main part (0747501586) has 778 pieces in inventory but represents obsolete stock with no replenishment capability.

Mounting and Termination: The substitute part specifies through-hole, right-angle mounting with press-fit termination and includes EMI shielding with light pipe features, providing enhanced performance characteristics compared to the main part's unspecified mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0747503586 directly replace the 0747501586 in existing designs?

A: Yes. Both parts are QSFP+ connectors within the Molex 74750 series family, sharing the same base product number. The substitute part is the manufacturer-recommended replacement for the obsolete main part. Design verification should confirm that the through-hole, right-angle mounting and press-fit termination are compatible with the target application's PCB layout and assembly process.

Q: What is the primary reason for substitution?

A: The Molex 0747501586 is classified as obsolete and no longer manufactured. The 0747503586 is the active, manufacturer-recommended equivalent that maintains QSFP+ connector compatibility and the 074750 product platform.

Q: Are there differences in environmental handling between these parts?

A: The main part specifies Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints. The substitute part lists MSL as Not Applicable, which is typical for cage assemblies. Both parts are RoHS compliant and suitable for standard industrial and commercial environments.

Q: What are the key mechanical differences?

A: The substitute part (0747503586) specifies through-hole, right-angle mounting with press-fit termination, whereas the main part does not provide detailed mounting specifications. The substitute also includes EMI shielding in addition to light pipe features. These specifications should be verified against the target PCB design and assembly capabilities.

Q: Is the substitute part available for immediate procurement?

A: Yes. The Molex 0747503586 has 888 pieces in current stock as new original inventory, ensuring immediate availability. The main part, while having 778 pieces in stock, represents obsolete inventory with no manufacturer replenishment.

Q: Are there any export or regulatory restrictions on the substitute part?

A: The substitute part carries an ECCN classification of EAR99, which is the standard commercial classification for most electronic components and indicates no specific export restrictions beyond standard commercial practices.
