SS-6488S-A-NF-01 Equivalent & Substitute Parts

Part Overview

The SS-6488S-A-NF-01 is a modular jack connector manufactured by Stewart Connector, designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielding. This through-hole solder-terminated connector features an EMI finger and board lock mechanism, operating across -40°C to 85°C. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Connector Type & Configuration: Must be 8p8c (RJ45, Ethernet) jack modular connector
• Mounting & Orientation: Through-hole mounting with 90° right-angle orientation required
• Termination: Solder termination mandatory
• Shielding: Shielded construction required
• Tab Direction: Down-facing tab required
• Contact Finish: Gold plating required
• Operating Temperature: Must support -40°C to 85°C range
• Moisture Sensitivity: MSL 1 (Unlimited) required

All five substitute parts meet these core substitution criteria. Variations in contact material (Phosphor Bronze vs. Copper Alloy), contact finish thickness, housing material (Polyamide/Nylon vs. Thermoplastic vs. Polyester), and feature details (Board Lock vs. Board Guide) do not prevent functional substitution within the specified electrical and mechanical envelope.

Engineering Selection Recommendations

Primary Recommendation: 6116526-1 (TE Connectivity AMP Connectors)

The 6116526-1 is the manufacturer-recommended primary substitute. It maintains full electrical and mechanical compatibility with the SS-6488S-A-NF-01 across all critical parameters: 8p8c configuration, 90° right-angle orientation, through-hole solder termination, shielded construction, and -40°C to 85°C operating range. The part is active in production with RoHS compliance certification and substantial inventory availability (80,498 pcs). Contact finish thickness of 50.0µin exceeds the original specification, providing enhanced durability.

Secondary Recommendations: A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, A-2004-2-3-LP/FS-N (Assmann WSW Components)

All three Assmann variants meet core substitution criteria with active product status and ROHS3 compliance. These parts differ only in contact finish thickness (15.0µin, 30.0µin, and 50.0µin respectively). Selection among these variants depends on application-specific contact durability requirements. The A-2004-2-2-LP/FS-N variant matches the original 30.0µin finish thickness exactly.

Alternative Consideration: 7499010122 (Würth Elektronik)

The 7499010122 meets most core parameters but has two limiting factors: vertical orientation (not 90° right-angle) and reduced operating temperature range (0°C to 70°C, not -40°C to 85°C). This part is suitable only for applications that do not require the full temperature range or right-angle mounting geometry.

Frequently Asked Questions (FAQ)

Q: Can the 7499010122 substitute for the SS-6488S-A-NF-01 in all applications?

A: No. The 7499010122 has vertical orientation instead of 90° right-angle, and its operating temperature range is 0°C to 70°C versus the required -40°C to 85°C. Use this part only if your application does not require right-angle mounting or the full temperature range.

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

A: The A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, and 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. Select based on contact durability requirements for your application.

Q: Is the TE Connectivity 6116526-1 a direct replacement?

A: Yes. The 6116526-1 maintains full compatibility across all critical parameters: 8p8c configuration, 90° right-angle orientation, through-hole solder termination, shielded construction, and -40°C to 85°C operating range. It is the manufacturer-recommended primary substitute.

Q: Do all substitute parts have the same contact material?

A: No. The original SS-6488S-A-NF-01 uses Copper Alloy contacts, while the TE Connectivity 6116526-1 and all Assmann variants use Phosphor Bronze. Both materials are acceptable for 8p8c Ethernet applications and do not prevent functional substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity 6116526-1 is RoHS Compliant, and all Assmann variants are ROHS3 Compliant. The original SS-6488S-A-NF-01 RoHS status is not specified.

Q: What is the significance of the contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. Thicker finishes (50.0µin) provide longer service life under repeated mating cycles. The original specification is 30.0µin; the A-2004-2-2-LP/FS-N matches this exactly, while other variants offer thinner (15.0µin) or thicker (50.0µin) options.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your PCB layout accommodates the through-hole footprint. All substitute parts use identical through-hole mounting with the same pin configuration and spacing. Verify that your board design supports the specific housing material and mechanical features (board lock vs. board guide) if applicable.
