Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Connector Style: LC
• Connector Type: Plug
• Simplex/Duplex Configuration: Simplex
• Fiber Core Diameter: 50µm
• Fiber Cladding Diameter: 125µm
• Cable Diameter: 2.0mm
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Lock
• Ferrule Material: Zirconia, Ceramic
• Body Material: Plastic
• Features: Dust Cap, Strain Relief

The FLCSMBLY part number meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors are manufactured by Panduit Corp and maintain identical mechanical and optical interface specifications. The FLCSMBLY is currently in active product status, providing continuity for applications previously utilizing the obsolete NKFLCSMBL.

Parameter Comparison

Engineering Selection Recommendations

The FLCSMBLY is the direct substitute for the obsolete NKFLCSMBL. Selection of FLCSMBLY is supported by the following factors:

Compliance and Regulatory Alignment: Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring regulatory continuity in procurement and deployment.

Product Status: The FLCSMBLY holds active product status with Panduit Corp, providing assured supply chain availability and ongoing manufacturer support. The NKFLCSMBL obsolete status necessitates transition to an actively maintained equivalent.

Mechanical and Optical Interface Compatibility: All critical mechanical parameters—connector style, type, simplex configuration, fiber dimensions, cable diameter, mounting type, fastening mechanism, and ferrule/body materials—are identical between the two parts. This ensures direct physical and functional interchangeability in existing installations.

Performance Characteristics: The FLCSMBLY demonstrates improved optical performance with specified reflection characteristics (-20dB) and documented attenuation (-0.3dB), providing measurable performance data for system design and validation purposes.

Frequently Asked Questions (FAQ)

Q: Can FLCSMBLY directly replace NKFLCSMBL in existing installations?

A: Yes. Both connectors share identical mechanical specifications including LC connector style, simplex configuration, 50µm core/125µm cladding fiber dimensions, 2.0mm cable diameter, latch lock fastening, and zirconia ceramic ferrule construction. Physical and functional interchangeability is confirmed.

Q: What are the differences between NKFLCSMBL and FLCSMBLY?

A: The primary differences are product status (NKFLCSMBL is obsolete; FLCSMBLY is active), series designation (NetKey® versus OptiCam®), housing and boot colors, and documented optical performance specifications. FLCSMBLY provides specified reflection performance (-20dB) and attenuation (-0.3dB), whereas NKFLCSMBL attenuation is specified as -0.1dB with reflection unspecified.

Q: Are there packaging differences between these parts?

A: NKFLCSMBL packaging is not specified in available documentation. FLCSMBLY is supplied in bulk packaging. Confirm packaging requirements with supplier specifications for procurement planning.

Q: Do both parts support multimode fiber applications?

A: Yes. NKFLCSMBL is specified for multimode OM2 operation. FLCSMBLY is specified for multimode operation. Both connectors accommodate 50µm core multimode fiber with 125µm cladding diameter.

Q: Are regulatory certifications equivalent between the two parts?

A: Yes. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8536.70.0000), ensuring regulatory compliance continuity.

Q: What inventory status should be considered for procurement decisions?

A: NKFLCSMBL has 887 pieces in stock but is obsolete. FLCSMBLY has 814 pieces in stock and is actively maintained. For new deployments and long-term supply assurance, FLCSMBLY is the appropriate selection.
