Molex 1060043389 MTP-MTP Simplex Fiber Optic Coupler

Part Overview

The Molex 1060043389 is a simplex fiber optic coupler designed to connect two MTP receptacle connectors in a panel-mount, snap-in configuration. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The coupler supports both singlemode and multimode fiber applications with a polymer housing and includes integrated features such as a 45° angle, bezel, and shutter mechanism.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 1060043389 is determined by the following critical parameters:

• Connector Type: Both ends must be MTP receptacle connectors
• Configuration: Simplex operation (single fiber channel)
• Fiber Mode Support: Compatibility with singlemode and/or multimode applications
• Mounting Method: Panel mount configuration with snap-in capability
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part Molex 1061810007 maintains functional equivalence across all critical parameters. The primary differences are in housing material (Polyether Imide instead of Polymer), mounting flange design (flange-based instead of angle-based), and inclusion of a dust cap feature. These variations do not affect the core substitution relationship for MTP-to-MTP simplex coupling applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1061810007 is the designated manufacturer substitute for the obsolete Molex 1060043389. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current procurement and deployment.

The substitute part is currently in active production status with higher inventory availability (1098 units versus 627 units for the obsolete part). The housing material upgrade to Polyether Imide (PEI) with UL94 V-0 flammability rating provides enhanced material performance characteristics compared to the original polymer housing.

Functional compatibility is maintained across all MTP-to-MTP simplex coupling applications supporting both singlemode and multimode fiber. The flange-based mounting design of the substitute part represents a mechanical variation from the original 45° angle design; panel integration requirements must be evaluated for specific installation contexts.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1061810007 directly replace the 1060043389 in existing installations?

A: Both parts function as MTP-to-MTP simplex couplers with identical connector types and fiber mode support. The primary consideration is the mounting interface: the substitute uses a flange design versus the original 45° angle configuration. Panel cutout and mounting hardware compatibility must be verified for your specific installation.

Q: What are the key differences between these two parts?

A: The substitute part features Polyether Imide (PEI) housing with UL94 V-0 flammability rating instead of polymer housing, includes a dust cap feature, and uses a flange-based mounting approach. All electrical and optical characteristics remain equivalent for simplex MTP-to-MTP coupling applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 1060043389 and 1061810007 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for component procurement and deployment.

Q: Why is the original part listed as obsolete?

A: The Molex 1060043389 has been discontinued by the manufacturer. The 1061810007 represents the active production alternative that maintains functional equivalence for MTP-to-MTP simplex fiber optic coupling applications.

Q: Does the housing material change affect optical performance?

A: Housing material changes do not affect optical transmission characteristics. Both polymer and Polyether Imide (PEI) housings provide equivalent optical isolation and connector interface functionality for simplex MTP coupling.

Q: What is the significance of the UL94 V-0 rating on the substitute part?

A: UL94 V-0 indicates superior flame resistance of the Polyether Imide housing material. This certification provides enhanced material safety characteristics compared to the unspecified flammability rating of the original polymer housing.
