Molex 1000141340 ZQSFP+ Cage Connector Equivalent & Substitute Parts

Part Overview

The Molex 1000141340 is a ZQSFP+ Cage connector with spring finger design, classified as a Position Connector within the Pluggable Connectors category. This component is designated as Obsolete, indicating it is no longer in active production or supported by the manufacturer. Due to its obsolete status, sourcing original units becomes increasingly difficult, making identification of active equivalent parts essential for ongoing system maintenance, repairs, and new designs requiring compatible connector solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1000141340 is based on the following critical parameters that must align between the original and substitute component:

Primary Substitution Criteria:

• Connector Type: ZQSFP+ (maintains electrical and mechanical interface compatibility)
• Base Product Number: 100014 (indicates same product family and design lineage)
• Manufacturer: Molex (ensures design consistency and quality standards)
• Category: Pluggable Connectors (functional classification match)

Secondary Compatibility Factors:

• RoHS Compliance Status (regulatory alignment)
• Moisture Sensitivity Level (environmental handling requirements)
• Termination Method (electrical connection approach)
• Mounting Configuration (physical installation method)

The substitute part 1000143340 shares the same base product number (100014) and connector type (ZQSFP+), establishing it as the direct active equivalent within the Molex product portfolio. The transition from the obsolete 1000141340 to the active 1000143340 represents a product line evolution within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The original part 1000141340 carries an Obsolete designation, which restricts its availability for new procurement. The substitute part 1000143340 maintains Active status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards.

Compliance and Certification: Both components are manufactured by Molex and share the same base product number (100014), confirming they belong to the same connector family. The substitute part carries EAR99 export classification, indicating standard commercial availability without export restrictions. The original part's RoHS Compliant status aligns with the substitute's compliance profile.

Connector Family Alignment: Both parts are ZQSFP+ connectors, establishing electrical and mechanical interface compatibility. The shared base product number confirms that the substitute represents the current production equivalent within Molex's product portfolio.

Functional Equivalence: The substitute part 1000143340 is the manufacturer-recommended replacement, as indicated in the original part's substitution field. This designation confirms that Molex has validated the substitute as a direct functional equivalent for applications previously using the 1000141340.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 1000141340 listed as Obsolete? A: The 1000141340 has reached end-of-life status within Molex's product portfolio. Obsolete designation indicates the manufacturer no longer produces this component and has transitioned users to active alternatives.

Q: Is the Molex 1000143340 a direct replacement for the 1000141340? A: Yes. Both components are ZQSFP+ connectors sharing the same base product number (100014). The 1000143340 is the active equivalent and is listed as the manufacturer-recommended substitute.

Q: What are the key differences between these two parts? A: The primary differences are product status (Obsolete vs. Active) and connector configuration. The substitute features a cage with heat sink design, press-fit termination, through-hole right-angle mounting, and EMI shielding. The original part features spring finger design with unspecified mounting details.

Q: Are there compatibility concerns when substituting the 1000141340 with the 1000143340? A: Both parts maintain ZQSFP+ connector type compatibility. Design differences in mounting type (through-hole right-angle vs. unspecified original) and termination method (press-fit vs. unspecified original) require verification against specific application requirements.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute part? A: The substitute part 1000143340 lists MSL as Not Applicable, indicating different handling requirements compared to the original part's MSL 1 (Unlimited) rating.

Q: Can I use the 1000143340 in new designs? A: Yes. The 1000143340 is an Active product with current manufacturer support, making it suitable for new designs requiring ZQSFP+ cage connectors with the specified features (heat sink, EMI shielding, press-fit termination, through-hole right-angle mounting).

Q: What packaging options are available for the substitute part? A: The 1000143340 is available in Bulk packaging configuration.

Q: Are both parts RoHS Compliant? A: The original 1000141340 is explicitly RoHS Compliant. The substitute 1000143340 does not specify RoHS status in the provided data; verification with Molex is recommended for regulatory compliance confirmation.
