3M 8310-G Fiber Optic Connector Coupler - Equivalent & Substitute Parts

Part Overview

The 3M 8310-G is a simplex SC-to-SC fiber optic coupler designed for singlemode applications with panel mount, flange configuration. This component functions as a receptacle-to-receptacle adapter, enabling connection between two SC fiber optic connectors in a fixed installation. The 8310-G is discontinued at DiGi Electronics, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new installations where inventory is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 8310-G is determined by strict equivalence across the following critical parameters:

• Connector Configuration: SC Receptacle to SC Receptacle (simplex orientation)
• Optical Mode: Singlemode operation
• Mechanical Interface: Panel mount with flange mounting
• Functional Features: Angle polished ferrule with dust cap protection
• Environmental Classification: MSL 1 rating for moisture sensitivity

The Molex 1061613500 satisfies all substitution criteria. While this part introduces additional features (snap-in mounting capability, zirconia ferrule material, shutter mechanism) and enhanced compliance certifications, these represent functional enhancements rather than deviations from the core electrical and mechanical requirements of the 8310-G.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1061613500 is the qualified substitute for the 3M 8310-G based on functional equivalence and product availability. The 8310-G is discontinued, while the 1061613500 maintains active product status with current inventory availability (853 pcs in stock). Both components meet RoHS compliance requirements; the 1061613500 carries ROHS3 certification, representing current regulatory alignment. The 1061613500 includes additional mechanical features (snap-in mounting, shutter mechanism) and material specifications (polymer housing, zirconia ferrule) that do not conflict with the core SC simplex singlemode coupler application. Selection of the 1061613500 ensures long-term supply chain continuity and compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1061613500 directly replace the 3M 8310-G in existing installations?

A: Yes. Both components are SC simplex singlemode couplers with identical receptacle-to-receptacle configuration and panel mount flange mounting. The 1061613500 includes snap-in mounting capability as an additional feature, which does not prevent standard panel mount installation.

Q: What is the significance of the zirconia ferrule material in the Molex part?

A: The zirconia ferrule in the 1061613500 is a material specification provided in the component data. This material is standard in fiber optic connector applications and does not affect compatibility with SC connector interfaces.

Q: Does the shutter mechanism on the Molex part affect compatibility?

A: No. The shutter is a protective feature that enhances dust and contamination prevention during non-connection periods. It does not interfere with normal SC connector mating operations.

Q: Are there any packaging differences between these parts?

A: The 3M 8310-G packaging is not specified in the available data. The Molex 1061613500 is supplied in bag packaging. Verify packaging requirements for your procurement process.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate restriction of hazardous substances. ROHS3 represents the current regulatory iteration. The 1061613500 meets the latest compliance standard.

Q: Is the MSL 1 rating identical between both parts?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.
