Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 504646-8 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Style: SC
• Connector Type: Plug
• Simplex/Duplex Configuration: Simplex
• Mode: Singlemode
• Cable Diameter: 3.0mm
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-In
• Housing Color: Blue

Secondary Compatibility Criteria:

• Fiber Cladding Diameter: 126µm (where specified)
• Ferrule Material: Ceramic or equivalent ceramic-class materials

The HellermannTyton FCSCSM meets the primary compatibility criteria as an SC simplex plug connector with singlemode capability, 3.0mm cable diameter, snap-in fastening, and blue housing. While the FCSCSM does not specify fiber cladding diameter in the provided data, it maintains functional equivalence through matching connector geometry, fastening mechanism, and operational configuration.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 504646-8 (Original Part): The original part is classified as obsolete and carries a "Not applicable" RoHS status. Current inventory availability is 1041 pieces. This part should be selected only when existing system documentation explicitly specifies the 504646-8 designation or when ceramic ferrule construction is a documented requirement.

HellermannTyton FCSCSM (Substitute Part): The FCSCSM is an active product with RoHS compliance certification, providing regulatory advantage for new installations and long-term system deployments. Current inventory availability is 1068 pieces. The FCSCSM maintains functional equivalence across all primary connector parameters and offers the additional benefit of active product status with ongoing manufacturer support. The zirconia ferrule material in the FCSCSM provides performance characteristics suitable for SC simplex singlemode applications.

Selection between these parts should be based on system requirements regarding product lifecycle status and regulatory compliance. The FCSCSM is suitable for applications where RoHS compliance and active product support are required. The 504646-8 remains valid for legacy system maintenance where specific part number compatibility is mandated.

Frequently Asked Questions (FAQ)

Q: Can the HellermannTyton FCSCSM directly replace the TE Connectivity 504646-8 in existing installations?

A: The FCSCSM is functionally equivalent for SC simplex singlemode fiber optic applications. Both connectors share identical connector style, type, simplex configuration, singlemode mode, cable diameter, mounting type, fastening mechanism, and housing color. Physical compatibility and optical performance are maintained across the substitution.

Q: What is the difference between ceramic and zirconia ferrule materials in these connectors?

A: Both ceramic and zirconia are ceramic-class ferrule materials used in fiber optic connectors. The TE Connectivity 504646-8 specifies ceramic ferrule construction, while the HellermannTyton FCSCSM uses zirconia ferrule material. Both materials are suitable for SC simplex singlemode connector applications and provide equivalent performance characteristics for the specified 126µm cladding diameter fiber.

Q: Why is the TE Connectivity 504646-8 classified as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production and support for this part number. The HellermannTyton FCSCSM, classified as an active product, represents the current equivalent offering with ongoing manufacturer availability and support.

Q: Are there packaging differences between these two connectors?

A: The TE Connectivity 504646-8 is supplied in unspecified packaging, while the HellermannTyton FCSCSM is supplied in bulk packaging. Both connectors maintain identical functional specifications and are suitable for the same applications.

Q: What does the MSL 1 (Unlimited) rating indicate?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these connectors have no moisture sensitivity restrictions and do not require special handling, storage, or baking procedures prior to installation. Both the 504646-8 and FCSCSM carry this rating.

Q: Are both connectors compliant with export regulations?

A: Both the TE Connectivity 504646-8 and HellermannTyton FCSCSM are classified under ECCN EAR99 and HTSUS code 8536.70.0000, indicating equivalent export classification status.
