Substitute Part Grouping Explanation

Substitution of the ARJM11C7-516-KB-EW4 is determined by strict alignment of the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port, 8-core jack
• Mounting & Orientation: Through hole, 90° right-angle configuration
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
• Termination Method: Solder-based PCB attachment
• Shielding & EMI Protection: Shielded construction with EMI finger
• Mechanical Features: Board lock mechanism
• Environmental Compliance: ROHS3 and REACH compliance maintained

The substitute part 5-6605809-5 (TRP Connector B.V., MagJack® series) satisfies all mandatory substitution criteria. Both components are classified as modular connectors with identical functional specifications for Ethernet connectivity, mechanical mounting, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 5-6605809-5 (TRP Connector B.V.) is the qualified substitute for the obsolete ARJM11C7-516-KB-EW4. Selection is based on:

• Functional Equivalence: Both components meet identical RJ45 Ethernet specifications (10/100/1000 Base-T, AutoMDIX)
• Mechanical Compatibility: Matching through-hole, 90° right-angle mounting with board lock features
• Regulatory Compliance: Both maintain ROHS3 and REACH compliance with identical MSL ratings
• Product Availability: The substitute is classified as Active with current inventory, ensuring production continuity
• Electrical Performance: Equivalent shielding, EMI protection, and gold contact finish specifications

The 0.012" (0.30mm) difference in height above board (14.10mm vs. 13.80mm) is within standard PCB layout tolerances and does not impact functional performance or mechanical fit in standard RJ45 connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-6605809-5 directly replace the ARJM11C7-516-KB-EW4 without PCB redesign?

A: Yes. Both connectors share identical mounting footprints, through-hole termination, and 90° right-angle orientation. The minimal height variance (0.30mm) is within standard PCB design tolerances and does not require layout modifications.

Q: Are there electrical performance differences between these two RJ45 connectors?

A: No. Both components support identical 10/100/1000 Base-T Ethernet with AutoMDIX functionality, shielded construction with EMI fingers, and gold contact finishes. The 5-6605809-5 includes integrated decoupling capacitance as an additional feature.

Q: What is the significance of the "Active" product status for the substitute part?

A: Active status indicates the 5-6605809-5 is currently manufactured and available for procurement. This ensures long-term supply chain stability and eliminates the obsolescence risk associated with the ARJM11C7-516-KB-EW4.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both are
