TE Connectivity 558341-1 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 558341-1 is a Jack Modular Connector with 8p8c (RJ45, Ethernet) configuration, featuring 90° right-angle orientation and unshielded design rated for Cat5 applications. This connector is designed for through-hole solder termination with a board guide feature and operates across the temperature range of -40°C to 85°C.

The 558341-1 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design requirements and component procurement. The substitute part 5558341-1 provides direct functional equivalence while maintaining active product status and improved compliance characteristics.

Substitute Part Grouping Explanation

Substitution of the obsolete 558341-1 with the active 5558341-1 is based on strict electrical and mechanical parameter equivalence. Both connectors maintain identical specifications across all critical functional parameters:

Key Parameters Determining Substitution Validity:

• Connector type and contact configuration (8p8c RJ45 jack)
• Orientation and mounting geometry (90° right-angle, through-hole)
• Electrical rating and performance category (Cat5)
• Contact material and finish specifications (Phosphor Bronze with 50.0µin gold plating)
• Housing material and mechanical dimensions (Polyamide/Nylon construction)
• Operating temperature envelope (-40°C to 85°C)
• Termination method (solder)
• Shielding classification (unshielded)

The primary distinction between these parts is product lifecycle status and packaging format. The 5558341-1 represents the current active equivalent with enhanced RoHS compliance and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 5558341-1 is the direct functional equivalent for the obsolete 558341-1 and is suitable for all applications requiring 8p8c RJ45 jack connectors with 90° right-angle through-hole solder termination in Cat5 rated unshielded configurations.

Selection Basis:
