SS-6488S-A-NF-SB04 Equivalent & Substitute Parts

Part Overview

The SS-6488S-A-NF-SB04 is a modular jack connector manufactured by Stewart Connector, designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielding. This connector features through-hole solder termination, board lock functionality, and operates across -40°C to 85°C. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-6488S-A-NF-SB04 is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Jack (modular)
• Contact configuration: 8p8c (RJ45, Ethernet)
• Number of ports: 1
• Orientation: 90° angle (right)
• Mounting type: Through hole
• Termination: Solder
• Shielding: Shielded

Secondary Compatibility Criteria:

• Board lock feature presence
• Operating temperature range compatibility (minimum -40°C, maximum 85°C or higher)
• Contact finish: Gold
• Moisture sensitivity level: 1 (Unlimited)
• REACH compliance status

All identified substitute parts meet these primary criteria. Variations in contact material (phosphor bronze vs. copper alloy), contact finish thickness, housing material, and additional features (EMI finger, specific ratings) represent acceptable engineering variations that do not compromise functional interchangeability in standard 8p8c modular jack applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SS-6488-NF-SB04

The SS-6488-NF-SB04 from Stewart Connector is the direct active equivalent. It maintains identical electrical and mechanical specifications to the obsolete SS-6488S-A-NF-SB04, including contact configuration, orientation, termination method, operating temperature range, and board lock features. This part is ROHS3 compliant and currently in active production status with 1160 units in stock.

Secondary Recommendations: Assmann WSW A-2004 Series

The A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, and A-2004-2-3-LP/FS-N represent functionally equivalent alternatives. These parts maintain all primary compatibility criteria with variations limited to contact material (phosphor bronze), contact finish thickness (15.0µin to 50.0µin), and housing material (polyester). All three variants are ROHS3 compliant and active products with inventory availability ranging from 768 to 937 units.

Alternative Options: Phoenix Contact 1653087 and Hirose TM11R-5N2-88(50)

The Phoenix Contact 1653087 and Hirose TM11R-5N2-88(50) provide additional substitution paths with enhanced EMI shielding through integrated EMI finger design. Both maintain core 8p8c jack functionality with through-hole solder termination and board lock features. Operating temperature ranges are reduced (-25°C to 80°C) compared to the main part specification. Both are ROHS3/RoHS compliant and active products.

Limited Compatibility: Würth Elektronik 74990111215

The 74990111215 meets primary substitution criteria but operates within a narrower temperature range (0°C to 70°C), which may restrict deployment in extended temperature environments. This part includes integrated LED indicators (yellow-green) and AutoMDIX functionality specific to 10/100 Base-T applications. Selection should be limited to applications where the reduced temperature range and additional features are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the SS-6488S-A-NF-SB04?

A: Yes, all listed substitute parts meet the primary compatibility criteria for 8p8c modular jack connectors with 90° right-angle orientation, through-hole solder termination, and shielding. The SS-6488-NF-SB04 is the most direct equivalent. Other substitutes introduce acceptable variations in contact material, finish thickness, and housing material that do not affect functional interchangeability in standard Ethernet applications.

Q: What is the difference between the Assmann WSW A-2004 variants?

A: The three Assmann WSW variants (A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, A-2004-2-3-LP/FS-N) differ only in contact finish thickness: 15.0µin, 30.0µin, and 50.0µin respectively. All other electrical and mechanical parameters are identical. Selection between variants depends on contact durability requirements for your specific application.

Q: Why does the Würth Elektronik 74990111215 have a narrower operating temperature range?

A: The 74990111215 operates from 0°C to 70°C, compared to the main part's -40°C to 85°C range. This reflects design specifications for the WE-RJ45 LAN series optimized for standard commercial networking environments. Use this part only in applications where the reduced temperature range is acceptable.

Q: What does EMI Finger shielding mean?

A: EMI finger shielding refers to integrated conductive fingers within the connector housing that provide enhanced electromagnetic interference suppression. The Phoenix Contact 1653087 and Hirose TM11R-5N2-88(50) include this feature. It is an enhancement that does not compromise compatibility with standard 8p8c applications.

Q: Are all substitute parts ROHS compliant?

A: Yes, all active substitute parts listed are either ROHS3 compliant or RoHS compliant. The obsolete SS-6488S-A-NF-SB04 does not specify RoHS status. All substitutes meet current environmental compliance requirements.

Q: What packaging options are available?

A: Packaging varies by manufacturer: Stewart Connector SS-6488-NF-SB04 is supplied in tubes, Phoenix Contact 1653087 in bulk, Würth Elektronik 74990111215 in tubes, Assmann WSW A-2004 series in trays, and Hirose TM11R-5N2-88(50) in trays. Confirm packaging requirements with your procurement process.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts are mechanically and electrically compatible for PCB integration. However, maintaining a single part number per design is recommended for manufacturing consistency, supply chain management, and quality control purposes.
