Engineering Selection Recommendations

Product Status Consideration: The Molex 1000142748 is classified as Obsolete and carries an OBSOLETE ECCN designation. The substitute part 1000143748 maintains Active product status with current regulatory compliance (ECCN EAR99, HTSUS 8538.90.8180), ensuring ongoing manufacturer support, availability, and compliance with current export and trade regulations.

Inventory and Supply Chain: While the main part currently maintains 854 pieces in stock, the substitute part provides superior long-term supply assurance with 1,097 pieces available and active production status. For new designs and long-term production planning, the substitute part is the appropriate selection.

Regulatory Compliance: The transition from OBSOLETE classification to EAR99 classification reflects current regulatory framework alignment. The substitute part's HTSUS code 8538.90.8180 provides clear tariff and trade classification for procurement and logistics purposes.

Family Continuity: Both parts share the base product number 100014, confirming that the substitute part represents the current generation within the same connector family, maintaining design philosophy and ecosystem compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 1000142748 listed as Obsolete?

A: The Molex 1000142748 has reached end-of-life status and is no longer in active production. Molex has transitioned this product line to newer designs within the same base product family (100014 series).

Q: Is the Molex 1000143748 a direct replacement for the 1000142748?

A: Both parts share the same base product number (100014) and manufacturer, confirming they belong to the same connector family. The 1000143748 represents the active substitute within this family. Specific mechanical and electrical compatibility must be verified against your application requirements, particularly regarding connector type (ZQSFP+ vs. Position Connector), mounting configuration (Through Hole, Right Angle), and termination method (Press-Fit).

Q: What are the key differences between these parts?

A: The substitute part 1000143748 specifies ZQSFP+ connector type with Cage with Heat Sink styling, Through Hole Right Angle mounting, and Press-Fit termination. The original part 1000142748 is documented as a Position Connector with unspecified mounting and termination details. The substitute includes EMI Shielding and Light Pipe features.

Q: What does the ECCN classification change from OBSOLETE to EAR99 mean?

A: The OBSOLETE ECCN designation reflects the part's end-of-life status. The substitute part's EAR99 classification indicates it is subject to current U.S. export control regulations but is generally authorized for export to most destinations without specific licensing requirements. This ensures compliance with current trade and export frameworks.

Q: How should I approach transitioning from the 1000142748 to the 1000143748?

A: Verify that the substitute part's specifications—including connector type (ZQSFP+), mounting style (Through Hole, Right Angle), termination method (Press-Fit), and features (EMI Shielded, Light Pipe)—align with your application's mechanical and electrical requirements. Confirm PCB layout compatibility with the Right Angle mounting configuration and Press-Fit termination method.

Q: Is inventory availability a concern for the 1000142748?

A: While 854 pieces are currently in stock, the Obsolete status indicates no future production. For applications requiring long-term supply assurance, the Active status of the 1000143748 with 1,097 pieces in inventory provides superior availability and production continuity.
