SS-7188V-A-FLS Modular Connector: Equivalent & Substitute Parts

Part Overview

The SS-7188V-A-FLS is an 8p8c (RJ45, Ethernet) modular jack connector manufactured by Stewart Connector. This vertical, unshielded connector is designed for through-hole mounting with solder termination and supports Cat5e rated applications. The part is currently active in production with 1,042 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability in designs where specific manufacturer constraints do not apply.

Substitute Part Grouping Explanation

Substitute parts for the SS-7188V-A-FLS are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Connector Type: Jack (Modular)
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: Vertical
• Number of Ports: 1
• Number of Rows: 1
• Operating Temperature Range: -40°C ~ 85°C
• Housing Material: Thermoplastic
• Contact Finish: Gold
• Tab Direction: User Selectable
• LED Color: Does Not Contain LED

Allowable Variations in Substitution:

• Termination Type: Solder (main part) to Press-Fit (substitute parts)
• Shielding: Unshielded (main part) to Shielded (6116202-1 only)
• Category Rating: Cat5e (main part) to Cat5 (substitute parts)
• Contact Material: Copper Alloy (main part) to Phosphor Bronze (substitute parts)
• Contact Finish Thickness: 30.0µin (main part) to 50.0µin (substitute parts)
• Packaging: Tray (main part) to Tube (substitute parts)

The identified substitute parts maintain core electrical and mechanical compatibility while allowing for these specified parameter variations based on application flexibility.

Engineering Selection Recommendations

SS-7188V-A-FLS (Stewart Connector):

• Primary choice when solder termination is required for PCB assembly processes
• ROHS3 compliance provides the highest regulatory standard
• Copper alloy contacts with 30.0µin gold finish meet Cat5e specifications
• Unshielded configuration suitable for non-EMI-sensitive applications

6116201-1 (TE Connectivity AMP Connectors):

• Press-fit termination alternative for automated assembly or rework scenarios
• Maintains unshielded configuration matching the main part's electrical characteristics
• Cat5 rating supports legacy and standard Ethernet applications
• Phosphor bronze contacts with 50.0µin gold finish provide enhanced durability
• RoHS compliant with vendor-undefined REACH status

6116202-1 (TE Connectivity AMP Connectors):

• Shielded variant for applications requiring electromagnetic interference mitigation
• Press-fit termination compatible with automated assembly processes
• Cat5 rating appropriate for standard Ethernet deployments
• Phosphor bronze contacts with 50.0µin gold finish offer extended contact life
• RoHS compliant with vendor-undefined REACH status

All three parts maintain identical operating temperature ranges, housing materials, and mechanical form factors. Selection depends on termination method requirements, shielding necessity, and regulatory compliance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can 6116201-1 directly replace SS-7188V-A-FLS in existing designs?

A: Direct replacement is possible when the design accommodates press-fit termination instead of solder termination. The electrical and mechanical interfaces are equivalent. PCB pad design and assembly process compatibility must be verified.

Q: What is the difference between 6116201-1 and 6116202-1?

A: The primary difference is shielding. 6116201-1 is unshielded, matching the SS-7188V-A-FLS configuration. 6116202-1 is shielded and should be used only when electromagnetic interference protection is required. Both use identical press-fit termination and phosphor bronze contacts.

Q: Does the Cat5e to Cat5 rating difference affect compatibility?

A: Cat5e is a superset of Cat5 specifications. The SS-7188V-A-FLS (Cat5e) supports higher bandwidth than Cat5-rated substitutes. Substitutes are compatible with Cat5e applications but do not guarantee Cat5e performance levels.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. SS-7188V-A-FLS is supplied in Tray packaging, while 6116201-1 and 6116202-1 are supplied in Tube packaging. This affects handling, storage, and bulk ordering but does not impact electrical or mechanical performance.

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

A: SS-7188V-A-FLS has 30.0µin (0.76µm) gold finish, while substitutes have 50.0µin (1.27µm). Thicker plating on substitute parts provides enhanced wear resistance and contact durability over extended mating cycles.

Q: Are all three parts RoHS compliant?

A: Yes. SS-7188V-A-FLS is ROHS3 compliant. Both TE Connectivity substitutes are RoHS compliant. ROHS3 represents a more recent regulatory standard than RoHS. All parts meet current environmental compliance requirements.

Q: Which part should be selected for new designs?

A: Selection depends on assembly process capability and application requirements. For solder-based assembly, use SS-7188V-A-FLS. For press-fit assembly without shielding requirements, use 6116201-1. For press-fit assembly with EMI protection, use 6116202-1.
