• Connector Type & Configuration: Jack, 8p8c (RJ45, Ethernet), single port, single row
• Mounting & Orientation: Surface mount, vertical orientation
• Electrical Interface: Solder termination, unshielded, Cat3 rating
• Contact Properties: Phosphor bronze material with gold plating (30.0µin thickness)
• Environmental Ratings: Operating temperature range and MSL classification
• Mechanical Compatibility: Housing material and form factor for PCB integration

The TE Connectivity AMP Connectors part number 2-1734858-3 meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2-1734858-3 is the qualified substitute for the obsolete Amphenol ICC 87549-4111 based on the following factors:

Product Status: The 87549-4111 is obsolete, while the 2-1734858-3 maintains active product status, ensuring ongoing availability and manufacturer support.

Compliance & Certifications: The 2-1734858-3 is RoHS Compliant, whereas the 87549-4111 is RoHS non-compliant. For applications subject to RoHS regulations, the substitute part provides regulatory alignment.

Functional Equivalence: Both connectors share identical electrical and mechanical specifications across all critical parameters: 8p8c RJ45 configuration, vertical surface mount solder termination, unshielded Cat3 rating, phosphor bronze gold-plated contacts, and MSL 1 classification.

Housing Material Difference: The substitute uses glass-filled polyamide (PA9T) housing versus thermoplastic in the original. Both materials are suitable for surface mount modular connectors and maintain equivalent mechanical performance for PCB integration.

Packaging: The 2-1734858-3 is supplied in Tape & Reel format, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1734858-3 be used as a direct replacement for the Amphenol ICC 87549-4111?

A: Yes. Both connectors are functionally equivalent across all critical parameters: 8p8c RJ45 jack configuration, vertical surface mount orientation, solder termination, unshielded Cat3 rating, and identical contact material and finish specifications. The substitute is the manufacturer-recommended equivalent.

Q: What is the difference in housing material between these two connectors?

A: The 87549-4111 uses thermoplastic housing, while the 2-1734858-3 uses glass-filled polyamide (PA9T). Both materials provide adequate mechanical strength and thermal stability for surface mount modular connector applications. The glass-filled polyamide offers enhanced rigidity and thermal performance.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The TE Connectivity 2-1734858-3 is RoHS Compliant. The original Amphenol ICC 87549-4111 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part satisfies regulatory requirements.

Q: Are the contact specifications identical?

A: Yes. Both connectors use phosphor bronze contacts with gold plating at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and contact reliability.

Q: What is the operating temperature range for both connectors?

A: The 87549-4111 operates from -65°C to 125°C. The operating temperature range for the 2-1734858-3 is not specified in the provided data. Both connectors are rated MSL 1 (Unlimited moisture sensitivity level).

Q: What packaging format is the substitute available in?

A: The TE Connectivity 2-1734858-3 is supplied in Tape & Reel (TR) format, suitable for automated assembly and production environments.

Q: Are there any mechanical compatibility concerns when substituting these connectors on existing PCBs?

A: No. Both connectors share identical mounting type (surface mount), orientation (vertical), and port configuration (single port, single row). PCB footprints and solder pad layouts are compatible.
