Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1000141250 is determined by strict alignment of the following critical parameters:

• Connector Type: ZQSFP+ (electrical interface standard)
• Connector Style: Cage (mechanical form factor)
• Mounting Type: Through Hole, Right Angle (PCB integration method)
• Termination Method: Press-Fit (assembly compatibility)
• EMI Shielding: Required (electromagnetic compliance)

The substitute part 1000143250 maintains identical values across all critical parameters, establishing functional and mechanical equivalence. Both parts belong to the Molex 100014 series and support the same electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1000143250 is the direct functional equivalent for applications currently specified with the 1000141250. Both connectors share identical electrical interface specifications (ZQSFP+), mechanical form factor (cage style, right-angle through-hole), and assembly method (press-fit termination). The 1000143250 maintains active product status, ensuring ongoing availability and supply chain support.

Selection of the 1000143250 is appropriate for new designs and redesigns of existing applications. The transition from the obsolete 1000141250 to the 1000143250 requires no changes to PCB layout, assembly procedures, or electrical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1000143250 be used as a direct replacement for the 1000141250 in existing designs?

A: Yes. Both connectors are mechanically and electrically equivalent. They share identical ZQSFP+ interface specifications, cage-style form factor, right-angle through-hole mounting, and press-fit termination. No PCB redesign or assembly procedure modification is required.

Q: What is the primary reason for substitution?

A: The 1000141250 is classified as obsolete. The 1000143250 is the active equivalent part from Molex within the same 100014 series, ensuring continued supply availability.

Q: Are there differences in packaging between these parts?

A: Packaging information for the 1000143250 is not specified in the available data. Verify packaging requirements with the supplier or Molex technical documentation if packaging specifications are critical to your procurement process.

Q: Do both parts meet the same compliance standards?

A: The 1000141250 is confirmed ROHS3 compliant. RoHS compliance status for the 1000143250 is not specified in the provided data. Confirm compliance requirements with Molex or your quality assurance department.

Q: Are there any assembly or design considerations when transitioning to the 1000143250?

A: No design or assembly changes are required. The 1000143250 maintains identical mounting type (through-hole, right-angle), termination method (press-fit), and EMI shielding specifications. Existing assembly procedures and PCB designs are fully compatible.
