Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0747680506 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Base product number alignment (074768 series)
• Connector category classification (Pluggable Connectors)
• Ganged cage configuration (1 x 3 arrangement)
• QSFP interface compatibility
• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The Molex 0747683506 qualifies as a manufacturer-recommended substitute because it maintains the same base product family (074768), shares the QSFP 1X3 ganged cage architecture, and carries active product status with current manufacturing support. Both components are RoHS compliant and feature MSL 1 ratings, ensuring equivalent environmental handling and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0747683506 is the manufacturer-recommended equivalent for the obsolete Molex 0747680506. Selection of the substitute part is based on the following engineering factors:

Product Status Consideration: The 0747680506 carries obsolete designation, while the 0747683506 maintains active product status with current manufacturing support and documented availability (926 pcs in stock). This transition ensures long-term supply chain continuity.

Compliance Alignment: Both components are RoHS compliant, satisfying regulatory requirements for electronic component procurement in regulated industries and markets.

Connector Architecture: Both parts share the 074768 base product family and QSFP ganged cage configuration (1 x 3), ensuring mechanical and electrical interface compatibility within the same connector ecosystem.

Enhanced Features: The substitute part incorporates integrated heat sink and EMI shielding capabilities, providing thermal management and electromagnetic interference mitigation beyond the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0747683506 directly replace the 0747680506 in existing designs?

A: The 0747683506 shares the same base product family (074768) and QSFP 1X3 ganged cage architecture. Physical form factor compatibility depends on specific mounting requirements and available board space for the right-angle through-hole configuration and integrated heat sink. Design verification against mechanical drawings is required.

Q: What is the significance of the heat sink feature in the substitute part?

A: The integrated heat sink in the 0747683506 provides thermal dissipation for high-power QSFP+ module applications. This enhancement is not present in the original 0747680506 specification. Thermal performance requirements of the target application determine whether this feature is beneficial or requires design accommodation.

Q: Are there differences in moisture sensitivity handling between these parts?

A: The 0747680506 specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The 0747683506 does not specify MSL rating in the provided data. Procurement documentation should confirm MSL classification for the substitute part to ensure equivalent storage and handling protocols.

Q: What does "No Light Pipe" designation mean?

A: The "No Light Pipe" designation indicates the connector lacks integrated optical signal transmission pathways. This is a mechanical feature distinction and does not affect electrical connector functionality for standard QSFP module interfaces.

Q: How do the mounting configurations differ?

A: The 0747680506 mounting type is not specified in available data. The 0747683506 specifies through-hole, right-angle mounting with press-fit termination. Board layout and connector orientation requirements must be evaluated against the substitute part's specific mounting configuration.

Q: Is the EMI shielding feature in the substitute part a compatibility concern?

A: EMI shielding is an enhancement feature that does not create incompatibility. The shielded design provides additional electromagnetic interference protection, which is generally beneficial in high-speed signal environments. No design modifications are required to accommodate this feature.
