Substitute Part Grouping Explanation

Substitution of the Molex 1001140421 is determined by the following critical parameters:

Primary Substitution Criteria:

• Connector Type: zSFP+ (must match exactly)
• Connector Style: Cage, Ganged (1 x 4) configuration (must match exactly)
• Base Product Number: 100114 (indicates product family compatibility)
• Category: Pluggable Connectors (functional category)

Secondary Compatibility Factors:

• Product Status: Active status preferred for ongoing availability
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Mounting Type & Termination: May differ based on application requirements

The substitute part Molex 1001148421 shares the identical connector type, style, and base product number, confirming functional and mechanical compatibility within the zSFP+ ganged cage connector family. Differences in mounting type (Through Hole, Right Angle) and termination method (Press-Fit) represent design variations that do not affect core connector compatibility but may require board-level design consideration.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The Molex 1001148421 is the manufacturer-recommended substitute for the obsolete Molex 1001140421. Both components maintain identical zSFP+ connector type and ganged (1 x 4) cage configuration, ensuring functional compatibility within the 100114 product family.

Compliance & Regulatory Status:

Both parts are ROHS3 Compliant and carry equivalent regulatory standing. The substitute part carries an active ECCN classification (EAR99), whereas the obsolete part is marked OBSOLETE. This transition reflects the part's active production status and ensures compliance with current export and supply chain requirements.

Design Considerations:

The substitute part introduces Through Hole, Right Angle mounting with Press-Fit termination and EMI Shielding features. These design enhancements do not compromise connector compatibility but require verification of board layout and mounting orientation compatibility with the original application. The EMI Shielding feature provides additional electromagnetic interference protection not specified in the original part.

Inventory & Availability:

The substitute part (1001148421) is available in active production with 870 pieces in stock, compared to the obsolete part's limited remaining inventory of 774 pieces. Selection of the active substitute ensures long-term supply chain continuity and component availability for future maintenance cycles.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1001148421 directly replace the Molex 1001140421 in existing designs?

A: The 1001148421 is functionally compatible as a zSFP+ ganged (1 x 4) cage connector. However, the substitute part features Through Hole, Right Angle mounting with Press-Fit termination, whereas the original part's mounting specifications are not detailed. Board-level design verification is required to confirm mounting orientation and termination method compatibility with the existing PCB layout.

Q: What is the significance of the shared Base Product Number (100114)?

A: The identical Base Product Number indicates both parts belong to the same Molex product family and share core connector architecture. This classification confirms mechanical and electrical compatibility within the zSFP+ ganged cage connector series, supporting substitution validity.

Q: Are there regulatory or compliance differences between the two parts?

A: Both parts are ROHS3 Compliant and carry equivalent environmental compliance status. The substitute part holds an active ECCN classification (EAR99), whereas the obsolete part is marked OBSOLETE. This reflects the substitute's active production status and current regulatory standing.

Q: What additional features does the substitute part provide?

A: The Molex 1001148421 includes EMI Shielding, which provides electromagnetic interference protection. This feature is not specified in the original part documentation. EMI Shielding may enhance signal integrity in high-speed or electromagnetically sensitive applications.

Q: How should mounting type differences be evaluated?

A: The substitute part specifies Through Hole, Right Angle mounting with Press-Fit termination. The original part's mounting type is not detailed in available documentation. PCB design review is necessary to confirm that the Right Angle orientation and Press-Fit termination method are compatible with the intended application and board layout.

Q: Is the substitute part suitable for new designs?

A: Yes. The Molex 1001148421 is an active product with full production support, ROHS3 compliance, and enhanced features including EMI Shielding. It is suitable for both legacy system replacement and new design implementations requiring zSFP+ ganged (1 x 4) cage connectors.
