Substitute Part Grouping Explanation

The substitute part 7499011002A is classified as a direct equivalent based on the following critical parameters that determine functional interchangeability:

• Connector Type: RJ45 (identical)
• Number of Ports: 1 (identical)
• Mounting Type: Through Hole (identical)
• Orientation: 90° Angle (Right) (identical)
• Applications: 10/100 Base-T, AutoMDIX (identical)
• Height Above Board: 0.541" (13.75mm) (identical)
• Shielding: Shielded, EMI Finger (identical)
• Contact Material and Finish: Tin with Gold plating (identical)
• Operating Temperature Range: 0°C ~ 70°C (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Series: WE-RJ45 LAN (identical)

The primary distinction between the main part and its substitute is product status and packaging configuration. The 7499011002A is currently active in production with tube packaging, whereas the 7499011002 is obsolete with standard packaging.

Parameter Comparison

Engineering Selection Recommendations

The 7499011002A is the direct active equivalent for the obsolete 7499011002. Both parts maintain identical electrical and mechanical specifications, including connector type, port configuration, mounting method, orientation, shielding characteristics, and contact materials. Both parts satisfy ROHS3 compliance and REACH regulatory requirements.

The transition from 7499011002 to 7499011002A is recommended for new designs and production continuity. The substitute part is currently in active production status with established supply chain availability. Packaging differences (tube versus standard) do not affect functional performance and should be evaluated based on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can 7499011002A be used as a direct replacement for 7499011002 in existing designs?
