SS71800-033G Equivalent & Substitute Parts

Part Overview

The SS71800-033G is a modular jack connector manufactured by Stewart Connector, designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielding suitable for Cat5 networks. This connector features through-hole solder termination and is rated for operating temperatures between -40°C and 85°C.

The SS71800-033G is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS71800-033G is determined by strict alignment with the following critical parameters:

• Connector type must be jack
• Contact configuration must be 8p8c (RJ45, Ethernet)
• Port count must be 2
• Mounting method must be through hole
• Orientation must be 90° angle (right)
• Termination must be solder
• Shielding must be present
• Cat5 rating or equivalent must be maintained
• Operating temperature range must encompass -40°C to 85°C
• Tab direction must be down

The substitute part 5406443-1 (TE Connectivity AMP Connectors) meets all these criteria, making it a direct functional equivalent for the obsolete SS71800-033G.

Parameter Comparison

Engineering Selection Recommendations

The 5406443-1 from TE Connectivity AMP Connectors is the direct substitute for the obsolete SS71800-033G. Both connectors share identical functional specifications across all critical parameters required for 8p8c modular jack applications.

The 5406443-1 carries active product status, ensuring ongoing availability and supply chain support. This part is ROHS3 compliant and maintains full regulatory alignment with REACH and ECCN classifications matching the original part.

Contact material differs between the two parts (copper alloy versus phosphor bronze), and housing material varies (thermoplastic versus polyamide/nylon). These material differences do not affect electrical or mechanical compatibility for standard Cat5 Ethernet applications. Contact finish thickness is also slightly higher on the substitute part (50.0µin versus 30.0µin), which provides equivalent or improved durability.

Frequently Asked Questions (FAQ)

Q: Can the 5406443-1 be used as a direct replacement for the SS71800-033G?

A: Yes. Both connectors meet identical specifications for connector type, contact configuration, mounting method, orientation, termination, shielding, and operating temperature range. The 5406443-1 is functionally equivalent and mechanically compatible.

Q: What is the difference in contact material between these parts?

A: The SS71800-033G uses copper alloy contacts, while the 5406443-1 uses phosphor bronze contacts. Both materials support gold plating and maintain electrical performance for Cat5 applications. Phosphor bronze offers enhanced durability and spring characteristics.

Q: Are there packaging differences between these connectors?

A: The SS71800-033G packaging information is not specified in available data. The 5406443-1 is supplied in tray packaging. Packaging format does not affect connector performance or compatibility.

Q: Does the higher contact finish thickness on the 5406443-1 affect compatibility?

A: No. The 5406443-1 features 50.0µin (1.27µm) contact finish thickness compared to 30.0µin (0.76µm) on the SS71800-033G. Increased finish thickness provides equivalent or improved contact durability without affecting electrical or mechanical compatibility.

Q: What is the product status difference between these parts?

A: The SS71800-033G is obsolete, while the 5406443-1 is active. Active status ensures continued availability, technical support, and supply chain reliability for the 5406443-1.

Q: Are both parts compliant with current regulations?

A: Yes. Both connectors are REACH unaffected and classified as EAR99 for export control purposes. The 5406443-1 additionally carries ROHS3 compliance certification.
