Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 2040586102 is determined by the following critical parameters:

• Connector Type: QSFP-DD (Double Density) receptacle configuration
• Position Count: 152 positions (76 x 2 ganged arrangement)
• Connector Style: Receptacle with cage and integrated heat sink
• Mounting Configuration: Through-hole, right-angle orientation
• Termination Method: Press-fit contact termination
• Base Product Series: 204058 family
• Electrical & Environmental Compliance: RoHS3 compliance and MSL rating

The substitute part 2040588112 shares the base product number 204058 and maintains the QSFP-DD receptacle configuration with ganged 2x1 assembly and angled heat sink design, establishing functional equivalence within the Molex connector portfolio.

Parameter Comparison

Engineering Selection Recommendations

The Molex 2040588112 is the designated manufacturer substitute for the obsolete 2040586102. As an active product within the same 204058 base series, the 2040588112 provides continuity for applications requiring QSFP-DD receptacle connectors with ganged 2x1 configuration and integrated heat sink.

Selection of the 2040588112 is supported by:

• Shared base product family (204058) ensuring design compatibility
• Active product status providing ongoing availability and supply chain support
• Identical connector type and ganged assembly configuration
• Manufacturer designation as the recommended substitute

For applications where the original 2040586102 specifications are critical, design validation against the 2040588112 datasheet is necessary to confirm all electrical, mechanical, and environmental parameters meet application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the 2040586102 being discontinued? A: The 2040586102 is classified as obsolete. The manufacturer recommends transitioning to the 2040588112, which maintains the core QSFP-DD receptacle functionality within the active product portfolio.

Q: What are the key differences between the 2040586102 and 2040588112? A: Both connectors share the QSFP-DD receptacle type, ganged 2x1 configuration, and base product series (204058). The 2040588112 features an angled heat sink design. Complete specification comparison requires review of both datasheets for all electrical and mechanical parameters.

Q: Can the 2040588112 be used as a direct replacement? A: The 2040588112 is the manufacturer-designated substitute. Compatibility depends on PCB layout, mounting orientation, and thermal requirements. Physical dimensions and mounting hole patterns must be verified against application specifications.

Q: What is the ganged 2x1 configuration? A: The ganged 2x1 assembly consists of two QSFP-DD receptacle units stacked and mechanically coupled as a single connector module, providing 152 total positions (76 positions per unit).

Q: Are both parts RoHS compliant? A: The 2040586102 is ROHS3 compliant. RoHS compliance status for the 2040588112 is not specified in the provided data and should be confirmed with the manufacturer.

Q: What is the MSL rating and why does it matter? A: The 2040586102 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling. This classification should be verified for the 2040588112 to ensure equivalent handling requirements.
