Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1000141344 is based on the following critical parameters that must align between the original and substitute part:

Primary Substitution Criteria:

• Connector Type: Both parts must be ZQSFP+ connectors to ensure electrical and mechanical compatibility
• Base Product Number: Both parts share the base product number 100014, indicating they belong to the same connector family and platform
• Manufacturer: Molex maintains design consistency within its product families, ensuring functional equivalence
• RoHS Compliance: The substitute part must maintain RoHS Compliant status for regulatory alignment

Functional Compatibility: The substitute part (1000143344) is identified as the manufacturer-recommended replacement. While the original part is a spring finger assembly, the substitute is a cage connector with heat sink functionality. Both serve position connector roles within the ZQSFP+ connector ecosystem and share the same base product platform, establishing their substitution relationship.

Engineering Selection Recommendations

Primary Recommendation: Molex 1000143344

The Molex 1000143344 is the manufacturer-recommended substitute for the obsolete 1000141344. Selection of this part is based on the following engineering factors:

1. Product Status Alignment: The substitute part maintains Active product status, ensuring long-term availability and continued manufacturing support from Molex.

2. Regulatory Compliance: Both parts maintain RoHS Compliant certification, satisfying environmental and regulatory requirements for electronic component procurement.

3. Platform Compatibility: Both parts share the base product number 100014 and ZQSFP+ connector type, confirming they operate within the same connector platform and ecosystem.

4. Certification and Standards: The substitute part carries ECCN EAR99 classification and HTSUS code 8538.90.8180, indicating standard commercial electronic component status with no export restrictions.

5. Enhanced Features: The substitute part incorporates EMI shielding and heat sink functionality, providing additional performance benefits over the original spring finger assembly design.

For applications requiring the exact original configuration, inventory of 1105 pieces of the original part 1000141344 remains available. However, for new designs and long-term production requirements, the active substitute part 1000143344 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 1000141344 listed as Obsolete?

A: The 1000141344 has reached end-of-life status in Molex's product portfolio. The manufacturer has transitioned to the 1000143344 as the active replacement within the 100014 base product family. Obsolete designation indicates the part is no longer in active production, though existing inventory may remain available.

Q: Can the Molex 1000143344 directly replace the 1000141344 in existing designs?

A: Both parts are ZQSFP+ connectors sharing the base product number 100014 and RoHS Compliant status. The substitute part features enhanced specifications including EMI shielding and heat sink integration. Physical form factor and mounting differences (Through Hole, Right Angle with Press-Fit termination on the substitute) must be evaluated against the original application requirements.

Q: What is the difference between the spring finger assembly and the cage with heat sink design?

A: The original 1000141344 is a spring finger assembly serving as a position connector element. The substitute 1000143344 is a complete cage connector with integrated heat sink functionality. Both serve position connector roles within ZQSFP+ applications, but the substitute provides thermal management and EMI shielding capabilities.

Q: Are there any moisture sensitivity or environmental concerns with substitution?

A: The original part carries MSL 1 (Unlimited) rating. The substitute part is rated as Not Applicable for MSL, indicating it does not require moisture sensitivity precautions during storage and handling. This represents an improvement in manufacturing and logistics flexibility.

Q: What packaging format is the substitute part supplied in?

A: The Molex 1000143344 substitute is supplied in Tray packaging, suitable for automated assembly and high-volume production environments.

Q: Are both parts RoHS Compliant?

A: Yes. Both the original 1000141344 and substitute 1000143344 maintain RoHS Compliant certification, satisfying environmental regulations for lead-free and restricted substance requirements.
