Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-668802S-A-NF is determined by strict alignment with the following critical parameters:

• Connector Type & Configuration: Must be a jack modular connector with 8p8c (RJ45, Ethernet) contact arrangement
• Mechanical Compatibility: 90° right-angle orientation, through-hole mounting, 2-port configuration, and downward tab direction are mandatory
• Electrical Properties: Shielded design with gold-plated copper alloy or phosphor bronze contacts
• Termination: Solder termination required for PCB integration
• Environmental Ratings: Operating temperature range of -40°C to 85°C minimum
• Compliance: REACH Unaffected and EAR99 classification maintained across all substitutes

The identified substitute parts meet all mechanical and electrical requirements while offering improved availability and compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5406443-1 (TE Connectivity AMP Connectors)

The 5406443-1 is the preferred substitute due to its active product status, ensuring long-term availability and manufacturer support. It maintains full mechanical and electrical compatibility with the original SS-668802S-A-NF while offering ROHS3 compliance and identical operating temperature specifications. The phosphor bronze contact material provides equivalent performance to the copper alloy contacts of the original part. Current inventory of 2200 units supports immediate deployment.

Secondary Recommendation: 1688599 (Phoenix Contact)

The 1688599 serves as an alternative substitute with ROHS3 compliance and IP20 ingress protection rating. It maintains all critical mechanical parameters and operates within the required temperature range. However, this part is also listed as obsolete, limiting its suitability for long-term production use. The Cat5e rating provides enhanced performance margin over the original Cat5 specification.

Both substitutes maintain REACH Unaffected and EAR99 classification, ensuring regulatory compliance across international markets.

Frequently Asked Questions (FAQ)

Q: Can the 5406443-1 be used as a direct replacement for the SS-668802S-A-NF?

A: Yes. The 5406443-1 meets all mechanical and electrical requirements: 8p8c jack configuration, 90° right-angle orientation, through-hole solder termination, 2-port layout, shielded design, gold-plated contacts, and -40°C to 85°C operating range. The phosphor bronze contact material is functionally equivalent to the copper alloy contacts of the original part.

Q: What is the difference between Cat5 and Cat5e ratings?

A: Cat5e represents an enhanced specification of Cat5 cabling standards with improved performance characteristics. The 1688599 substitute with Cat5e rating is backward compatible with Cat5 applications and provides additional performance margin.

Q: Are there packaging differences between the substitutes?

A: Yes. The SS-668802S-A-NF original part packaging is not specified. The 1688599 is supplied in Bulk packaging, while the 5406443-1 is supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is the SS-668802S-A-NF listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 5406443-1 remains in active production, making it the recommended long-term solution for new designs and ongoing system support.

Q: Does the IP20 rating on the 1688599 affect compatibility?

A: No. IP20 ingress protection is an additional feature that does not impact electrical or mechanical compatibility. It indicates the connector provides protection against solid objects larger than 12mm and liquid ingress, which is beneficial for environmental robustness.

Q: Are all substitutes ROHS3 compliant?

A: The 5406443-1 and 1688599 are both ROHS3 compliant. The original SS-668802S-A-NF RoHS status is not specified in the provided data.
