Substitute Part Grouping Explanation

Substitution between the TE Connectivity 406549-1 and 2-406549-1 is valid based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for connector type, contact configuration, orientation, termination method, shielding architecture, and performance ratings. The substitution is determined by the following key parameters:

• Connector Type & Configuration: Both are jack modular connectors with 8p8c (RJ45, Ethernet) contact arrangement
• Physical Orientation: Both feature 90° right-angle mounting orientation
• Electrical Performance: Both maintain Cat5 rating with identical contact material (Phosphor Bronze) and gold finish specifications
• Shielding & EMI Protection: Both incorporate shielded construction with EMI finger design
• Environmental Compliance: Both meet ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity requirements
• Operating Conditions: Both operate across the identical temperature range of -40°C to 85°C

The primary distinction between these parts is product status and packaging format. The 406549-1 is obsolete, while 2-406549-1 maintains active product status with tray packaging, making it the recommended substitute for new designs and ongoing procurement.
