FO-EX-LCAD2 Fiber Optic Connector Coupler - Equivalent & Substitute Parts

Part Overview

The FO-EX-LCAD2 is a simplex fiber optic coupler manufactured by JAE Electronics, designed to connect two LC receptacle connectors in a panel-mount, snap-in configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

The FO-EX-LCAD2 supports both singlemode and multimode fiber optic transmission across an operating temperature range of -40°C to 85°C. The coupler features a zirconia ferrule and includes a dust cap for connector protection during storage and non-use periods.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FO-EX-LCAD2 is determined by strict alignment of the following critical parameters:

• Connector interface: LC receptacle to LC receptacle configuration
• Simplex operation: Single fiber channel transmission
• Mounting method: Panel mount with snap-in mechanism
• Ferrule composition: Zirconia material for optical performance
• Operating temperature range: -40°C to 85°C minimum
• Dust cap inclusion: Required for connector protection

The substitute part 1061241100 (Molex) meets all these criteria. While the Molex part specifies singlemode fiber mode support compared to the FO-EX-LCAD2's singlemode/multimode capability, singlemode operation is a subset of multimode compatibility in terms of physical connector interface and mechanical fit. The housing material differs (polymer versus synthetic resin), but both materials provide equivalent mechanical protection and panel-mount functionality.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1061241100 serves as a direct functional substitute for the obsolete FO-EX-LCAD2. Both components share identical connector interfaces, simplex configuration, operating temperature specifications, and ferrule materials. The Molex part carries active product status with RoHS3 compliance and REACH unaffected designation, providing regulatory continuity for new designs and system upgrades.

The housing material difference (polymer versus synthetic resin) does not affect mechanical compatibility or panel-mount snap-in functionality. The Molex part's singlemode specification is compatible with systems designed for the FO-EX-LCAD2's multimode capability, as singlemode connectors operate within the same physical and optical interface standards.

Selection of the Molex 1061241100 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing LC receptacle fiber optic systems.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1061241100 replace the FO-EX-LCAD2 in existing installations?

A: Yes. Both couplers share identical LC receptacle-to-receptacle simplex configuration, panel-mount snap-in mechanism, operating temperature range, and ferrule material. Physical and optical interface compatibility is maintained.

Q: What is the difference between singlemode and multimode fiber mode support?

A: The FO-EX-LCAD2 supports both singlemode and multimode fiber transmission, while the Molex 1061241100 supports singlemode only. Singlemode operation is mechanically and optically compatible with multimode-capable connectors. Systems designed for singlemode fiber will operate without modification using either coupler.

Q: Are there packaging differences between these parts?

A: The FO-EX-LCAD2 packaging is not specified in available data. The Molex 1061241100 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same regulatory standards?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4030) classifications. The Molex 1061241100 carries RoHS3 compliance and REACH unaffected status. Verify regulatory requirements for your specific application and region.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the FO-EX-LCAD2 and Molex 1061241100 carry this rating.
