Substitute Part Grouping Explanation

Substitution of the obsolete Molex 1111123460 is determined by alignment across the following critical parameters:

Functional Equivalence Criteria:

• Connector Category: Pluggable Connectors
• Connector Type: SFP+
• Configuration: 1X4 Cage, Ganged
• Thermal Management: Integrated Net Heatsink
• Base Product Series: 111112

Compliance & Environmental Criteria:

• RoHS Compliance Status
• Moisture Sensitivity Level (MSL) rating
• ECCN classification for export control

Mechanical & Electrical Criteria:

• Connector Style: Cage, Ganged (1 x 4) with Heat Sink
• Mounting Type: Through Hole, Right Angle
• Termination Method: Press-Fit
• EMI Shielding: Present

The substitute part 1111124860 shares the same base product series (111112), identical connector type and configuration, and maintains equivalent thermal and EMI characteristics while transitioning to Active product status with current manufacturing support.

Engineering Selection Recommendations

For New Designs and Production: The Molex 1111124860 is the designated active substitute for the obsolete 1111123460. This part maintains functional and mechanical equivalence while providing current manufacturing support and supply chain continuity. The transition from Obsolete to Active product status ensures long-term component availability and compliance with current regulatory frameworks.

For Legacy System Support: Existing inventory of 1111123460 units (1130 pieces) remains available for maintenance and repair applications. However, new production should transition to 1111124860 to align with active product lines and eliminate future obsolescence risk.

Compliance Considerations: Both parts maintain RoHS Compliance status. The substitute part carries EAR99 ECCN classification, confirming standard export control treatment. The HTSUS code 8538.90.8180 applies to the active substitute for tariff and trade documentation purposes.

Frequently Asked Questions (FAQ)

Q: Can the 1111124860 directly replace the 1111123460 in existing PCB designs?

A: Yes. Both parts share identical connector type (SFP+), configuration (1X4 Cage, Ganged), mounting type (Through Hole, Right Angle), and termination method (Press-Fit). The mechanical and electrical interfaces are equivalent, permitting direct substitution without PCB redesign.

Q: What is the significance of the Base Product Number 111112?

A: The Base Product Number 111112 identifies the product family to which both parts belong. Shared base product numbers indicate that parts are within the same design series and are engineered for functional compatibility.

Q: Why is the obsolete part still in inventory?

A: The 1111123460 remains in stock (1130 pieces) for legacy system support, field repairs, and maintenance applications. However, new production should utilize the active substitute 1111124860.

Q: Are there differences in thermal performance between these parts?

A: Both parts incorporate integrated net heatsink designs for thermal management in SFP+ applications. Thermal characteristics are functionally equivalent based on the provided specifications.

Q: What does MSL 1 (Unlimited) mean for the obsolete part?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life and requires no special moisture control during storage or handling. The active substitute lists MSL as Not Applicable, which is standard for connector assemblies that do not require moisture sensitivity classification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1111123460 and 1111124860 carry RoHS Compliant status, confirming compliance with Restriction of Hazardous Substances regulations.

Q: What is the HTSUS code used for?

A: The HTSUS code 8538.90.8180 (applicable to the active substitute) is used for tariff classification, trade documentation, and customs purposes when importing or exporting the component.
