Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-009-AB-CW2 is the appropriate substitute for the obsolete ARJM11B1-001-AD-CW4. Both parts maintain identical electrical and mechanical specifications for 10/100 Base-T RJ45 connectivity with AutoMDIX support. The substitute part carries active product status, ensuring long-term availability and manufacturer support. Both parts satisfy ROHS3 compliance and REACH requirements, meeting current regulatory standards. The LED color difference (Green - Yellow vs. Green - Orange) and contact finish thickness variation do not affect functional compatibility or electrical performance in standard 10/100 Base-T applications. Selection of the active substitute part eliminates obsolescence risk while preserving design integrity.

Frequently Asked Questions (FAQ)

Q: Can ARJM11B1-009-AB-CW2 be used as a direct replacement for ARJM11B1-001-AD-CW4 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, mounting type, orientation, and electrical specifications for 10/100 Base-T applications. The connector footprint and PCB layout compatibility are maintained.

Q: What is the significance of the LED color difference between these parts?

A: The LED color difference (Green - Orange vs. Green - Yellow) is a visual indicator variation only and does not affect electrical performance or network functionality. Both configurations provide status indication for network link and activity.

Q: Does the contact finish thickness difference impact electrical performance?

A: No. Both contact finish thicknesses meet gold plating specifications for 10/100 Base-T RJ45 connectors. The difference does not affect signal integrity, impedance, or long-term reliability in standard applications.
