Equivalent & Substitute Parts: Molex 1001141421

Part Overview

The Molex 1001141421 is a zSFP+ Cage connector assembly with press-fit termination and integrated heat sink functionality. This component is classified as Obsolete and is no longer in active production. The part was designed for high-density optical transceiver applications requiring ganged (1 x 4) connector configurations with electromagnetic interference shielding.

Due to its obsolete status, sourcing new inventory from original manufacturing channels is limited. Identifying active equivalent parts ensures design continuity and supply chain reliability for applications currently utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1001141421 is based on the following critical parameters that must remain consistent:

Connector Type and Configuration: Both the original and substitute parts must be zSFP+ connectors with a ganged (1 x 4) cage configuration and integrated heat sink functionality.

Mounting and Termination: The substitute part must maintain through-hole, right-angle mounting with press-fit termination to ensure compatibility with existing printed circuit board layouts and assembly processes.

Base Product Family: Both parts share the same base product number (100114), confirming they belong to the same connector family and are designed for the same application class.

Electromagnetic Shielding: The substitute part includes EMI shielding and light pipe features, maintaining the signal integrity requirements of the original design.

The Molex 1001147421 meets all these substitution criteria and is currently in active production status, making it the appropriate replacement for the obsolete 1001141421.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1001147421 is the direct substitute for the obsolete Molex 1001141421. Both connectors share identical mechanical and electrical specifications for zSFP+ ganged (1 x 4) cage configurations with press-fit through-hole termination.

The substitute part is currently in active production status, ensuring reliable supply chain access and ongoing manufacturer support. The ECCN classification of EAR99 for the substitute part indicates standard commercial availability without export restrictions.

The transition from the obsolete part to the active substitute requires no design modifications to existing printed circuit board layouts or assembly procedures, as the connector footprint, mounting orientation, and termination method remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1001147421 be used as a direct replacement for the 1001141421 without PCB redesign?

A: Yes. Both connectors maintain identical through-hole, right-angle mounting configurations and press-fit termination methods. The connector footprint and board-level interface are compatible.

Q: What is the primary reason for substitution?

A: The original part (1001141421) is classified as obsolete and is no longer in active production. The substitute part (1001147421) is actively manufactured and provides equivalent functionality.

Q: Are there differences in moisture sensitivity handling between the two parts?

A: The original part carries an MSL rating of 1 (Unlimited), while the substitute part is classified as Not Applicable. This reflects differences in packaging and storage requirements, but does not affect the connector's operational performance in the application.

Q: Do both connectors support the same zSFP+ transceiver modules?

A: Yes. Both connectors are designed for zSFP+ optical transceiver modules in ganged (1 x 4) configurations. The cage design, heat sink integration, and electrical interface are identical.

Q: What export compliance considerations apply to the substitute part?

A: The substitute part (1001147421) carries an ECCN classification of EAR99, indicating it is subject to standard commercial export regulations. Verify compliance requirements for your specific end-use application and destination.
