TE Connectivity 558343-1 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 558343-1 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 board guide and panel stop features.

The 558343-1 carries an obsolete product status, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 558343-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Jack)
• Contact count and configuration (8p8c RJ45 Ethernet)
• Shielding classification (Unshielded)
• Category rating (Cat5)
• Contact material and finish specifications (Phosphor Bronze with 50.0µin gold plating)

Mechanical Compatibility Parameters:

• Orientation (90° right-angle)
• Mounting method (Through Hole)
• Termination type (Solder)
• Housing material (Polyamide/Nylon)
• Tab direction (Down)
• Integrated features (Board Guide, Panel Stops)

Environmental Parameters:

• Operating temperature range (-40°C ~ 85°C)

The substitute part 5558343-1 maintains complete equivalence across all specified parameters, with the primary distinction being product status (active versus obsolete) and packaging format (Tray versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5558343-1 serves as the direct active equivalent to the obsolete 558343-1 model. Selection between these parts is determined by application requirements and regulatory compliance mandates:

For New Designs and Production: The 5558343-1 is the specified selection. This part maintains complete electrical and mechanical equivalence while offering active product status and ROHS3 compliance. The part is currently in active production with confirmed inventory availability (2785 pieces).

For Legacy System Maintenance: The 558343-1 remains available in limited inventory (969 pieces) for applications where RoHS non-compliance is acceptable or where existing designs cannot accommodate compliance updates. This part should be phased out in favor of the 5558343-1 for long-term supply chain stability.

Compliance Considerations: The 5558343-1 provides ROHS3 compliance, addressing regulatory requirements for new equipment and systems subject to RoHS directives. The 558343-1 does not meet these requirements and should not be specified for applications requiring RoHS certification.

Packaging Considerations: The 5558343-1 is supplied in Tray packaging, which may differ from the original packaging format of the 558343-1. Verify packaging compatibility with existing procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the 5558343-1 be used as a direct replacement for the 558343-1 in existing designs?

A: Yes. The 5558343-1 maintains complete electrical and mechanical equivalence across all specified parameters including connector type, contact configuration, orientation, mounting method, termination type, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the primary reason for the product status change from obsolete to active?

A: The 5558343-1 represents the current production equivalent of the 558343-1. TE Connectivity has transitioned this connector family to active status with updated RoHS3 compliance. The 558343-1 is no longer manufactured.

Q: Are there differences in electrical performance between these two parts?

A: No. Both parts are rated for Cat5 Ethernet applications with identical contact materials (Phosphor Bronze), contact finish specifications (Gold, 50.0µin), and operating temperature ranges (-40°C ~ 85°C). Electrical performance is equivalent.

Q: What is the significance of the RoHS compliance difference?

A: The 5558343-1 is ROHS3 compliant, meeting current regulatory requirements for equipment sold in regions with RoHS directives. The 558343-1 is RoHS non-compliant. For new designs and systems subject to RoHS regulations, the 5558343-1 is required.

Q: Does the Tray packaging of the 5558343-1 affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Tray packaging is a supply format difference. Verify that Tray packaging is compatible with your assembly and procurement processes.

Q: Are both parts manufactured by the same company?

A: Yes. Both the 558343-1 and 5558343-1 are manufactured by TE Connectivity AMP Connectors. The 5558343-1 is the current production equivalent.

Q: What is the inventory status for each part?

A: The 558343-1 has 969 pieces available in stock (obsolete status). The 5558343-1 has 2785 pieces available in stock (active status). For new procurement, the 5558343-1 is recommended due to active production status and higher availability.

Q: Can these connectors be used in shielded applications?

A: No. Both the 558343-1 and 5558343-1 are unshielded connectors. They are not suitable for applications requiring electromagnetic shielding. Shielded RJ45 connectors must be specified separately.
