NKFLCSMAQ Fiber Optic Connector Equivalent & Substitute Parts

Part Overview

The NKFLCSMAQ is a fiber optic plug connector manufactured by Panduit Corp, classified as an LC simplex connector designed for multimode OM3 fiber applications. This connector features a 50µm fiber core diameter with 125µm cladding, operates in a free-hanging in-line configuration, and incorporates a latch lock fastening mechanism with dust cap and strain relief features.

The NKFLCSMAQ carries an obsolete product status. Identification of equivalent and substitute parts is necessary to maintain system compatibility, ensure continued availability of replacement components, and support ongoing network infrastructure requirements where this connector type is deployed.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Connector Style: LC
• Connector Type: Plug
• Simplex/Duplex Configuration: Simplex
• Fiber Cladding Diameter: 125µm
• Fiber Core Diameter: 50µm
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Lock
• Ferrule Material: Zirconia, Ceramic
• Features: Dust Cap, Strain Relief

Allowable Variation Parameters:

• Fiber Mode: Multimode OM3 or higher (OM4 compatible)
• Cable Diameter: Variation permitted within connector design specifications
• Housing Color and Boot Color: Cosmetic variation
• Series Designation: Different product series acceptable if core parameters match

The substitute part FLCSMCXAQY meets all mandatory matching parameters and represents an active product with extended multimode capability (OM3 and OM4 support).

Engineering Selection Recommendations

FLCSMCXAQY as Primary Substitute:

The FLCSMCXAQY is the direct substitute for the obsolete NKFLCSMAQ. Selection of this part is based on the following engineering criteria:

1. Product Status Alignment: FLCSMCXAQY carries active product status, ensuring ongoing availability, manufacturing support, and supply chain continuity.

2. Functional Equivalence: All critical connector parameters match the original specification, including LC style, simplex configuration, 50µm core diameter, 125µm cladding, latch lock fastening, and identical ferrule materials.

3. Enhanced Capability: FLCSMCXAQY supports both OM3 and OM4 multimode fiber standards, providing backward compatibility with OM3 systems while enabling deployment in OM4 infrastructure.

4. Compliance Consistency: Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS coding (8536.70.0000), ensuring regulatory and trade compliance equivalence.

5. Physical Integration: Identical mounting type (free hanging in-line), fastening mechanism (latch lock), and feature set (dust cap, strain relief) ensure mechanical and functional interchangeability.

Cable Diameter Consideration:

The FLCSMCXAQY features a 0.9mm cable diameter compared to the NKFLCSMAQ 2.0mm specification. This difference reflects the cable jacket diameter only and does not affect connector interface compatibility. Cable diameter selection depends on the specific fiber optic cable assembly being terminated and should be verified against the cable specification in the application.

Frequently Asked Questions (FAQ)

Q: Can FLCSMCXAQY directly replace NKFLCSMAQ in existing installations?

A: Yes. The FLCSMCXAQY meets all mandatory connector parameters for direct substitution. The connector interface, ferrule geometry, and mating characteristics are identical. Verification of cable diameter compatibility with the installed fiber optic cable is required.

Q: What is the significance of OM4 support in FLCSMCXAQY?

A: The FLCSMCXAQY supports both OM3 and OM4 multimode fiber standards. This represents an extended capability compared to the NKFLCSMAQ OM3-only specification. In OM3 systems, the connector operates within OM3 parameters. In OM4 systems, the connector supports the higher bandwidth capability of OM4 fiber. This does not affect backward compatibility with existing OM3 deployments.

Q: Why does FLCSMCXAQY have a different cable diameter?

A: Cable diameter (0.9mm versus 2.0mm) refers to the outer diameter of the fiber optic cable jacket, not the connector interface. The connector ferrule and mating interface remain identical. Cable diameter selection is determined by the specific fiber optic cable assembly specification. Verify that the cable diameter of the FLCSMCXAQY matches the cable being terminated.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS coding (8536.70.0000). Regulatory and trade compliance requirements are equivalent.

Q: What is the difference between NetKey® and OptiCam® series designations?

A: Series designation indicates the product line within Panduit's connector portfolio. NetKey® represents the legacy series (NKFLCSMAQ, obsolete status), while OptiCam® represents the current product series (FLCSMCXAQY, active status). Both series use identical LC connector technology and specifications for this simplex 50µm core application.

Q: Is the aqua boot color significant for substitution?

A: Boot color is a cosmetic identifier and does not affect functional compatibility. Both parts feature aqua boot color, providing visual consistency. Boot color selection in fiber optic connectors is typically used for network organization and identification purposes only.

Q: What inventory status should be considered for procurement?

A: NKFLCSMAQ inventory is listed as obsolete with 1021 pieces in stock. FLCSMCXAQY is an active product with 670 pieces in stock. For new installations or long-term system support, FLCSMCXAQY is the appropriate selection due to active product status and ongoing manufacturing availability.
