Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 2040586106 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Connector Type: QSFP-DD (Double Density)
• Connector Style: Receptacle with Cage, Ganged (2x1)
• Number of Positions: 152 (76 x 2)
• Mounting Type: Through Hole, Right Angle
• Termination: Press-Fit
• Features: EMI Shielded
• Contact Finish: Gold
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part Molex 2040588116 maintains functional and electrical equivalence through identical alignment with these parameters. The transition from obsolete to active product status enables continued component sourcing without design modification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 2040588116 serves as the direct functional equivalent to the obsolete Molex 2040586106. Both components maintain identical electrical and mechanical specifications across all critical parameters, including connector type, position count, mounting configuration, and termination method. The substitute part carries active product status, ensuring availability for procurement and production integration.

Both components satisfy RoHS compliance requirements and feature MSL 1 classification, indicating no moisture sensitivity constraints during storage and handling. The transition to the active substitute part eliminates supply chain risk associated with obsolete component sourcing while maintaining full design compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 2040588116 be used as a direct replacement for the 2040586106 in existing designs?
