Substitute Part Grouping Explanation

Substitute parts for the SS-668804-NF are identified based on strict alignment with the following critical parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Number of ports: 4
• Orientation: 90° angle (right)
• Mounting type: Through hole
• Termination: Solder
• Shielding: Unshielded
• Operating temperature range: -40°C ~ 85°C
• Tab direction: Down
• Features: Board guide

The identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications originally designed for the SS-668804-NF.

Parameter Comparison

Engineering Selection Recommendations

SS66800-017F (Stewart Connector): This part is the direct equivalent from the same manufacturer series. It maintains identical electrical and mechanical specifications to the SS-668804-NF while offering active product status and ROHS3 compliance. The SS66800-017F is available in higher inventory quantities and represents the primary substitute for obsolete stock replacement.

5557562-1 (TE Connectivity AMP Connectors): This cross-manufacturer substitute maintains all critical functional parameters including connector type, contact configuration, orientation, mounting, and termination method. The part differs in contact material composition (phosphor bronze versus copper alloy) and contact finish thickness (50.0µin versus 30.0µin), with a higher performance rating specification (Cat4 versus Cat5). This connector is RoHS compliant and carries active product status with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SS66800-017F be used as a direct replacement for SS-668804-NF?

A: Yes. Both parts share identical connector type, contact configuration, orientation, mounting method, termination, shielding, operating temperature range, and board guide features. The primary difference is product status: SS-668804-NF is obsolete while SS66800-017F is active.

Q: What are the differences between the Stewart Connector and TE Connectivity substitutes?

A: Both maintain core functional compatibility. Differences include contact material (copper alloy versus phosphor bronze), contact finish thickness (30.0µin versus 50.0µin), housing material composition (thermoplastic versus polyamide/nylon), and performance rating (Cat5 versus Cat4). These variations do not affect mechanical or electrical compatibility in standard 8p8c applications.

Q: Are there packaging differences between these parts?

A: Yes. SS-668804-NF packaging is not specified. SS66800-017F is supplied in tube packaging. 5557562-1 is supplied in tray packaging. Packaging selection may affect procurement quantities and handling procedures but does not impact functional performance.

Q: Do all three parts meet the same compliance standards?

A: All three parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS coding. SS66800-017F is ROHS3 compliant with MSL 1. 5557562-1 is RoHS compliant with MSL 1. SS-668804-NF REACH status is unaffected; 5557562-1 REACH status is vendor undefined.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility across standard industrial and commercial applications.
