Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100/1000 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

These parameters define the functional and mechanical compatibility envelope for RJ45 modular connectors in this application category. The substitute maintains electrical performance characteristics and physical form factor requirements for direct PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The 5-6605809-5 is an active product with current manufacturing support, addressing the supply discontinuation of the ARJM11C7-628-KB-EW2. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial networking applications.

The substitute part includes integrated decoupling capacitance and board lock features, providing enhanced electrical performance characteristics. The contact finish thickness of the substitute (50.0µin) exceeds that of the original part (6.00µin), supporting extended contact durability in high-cycle insertion environments.

Operating temperature range differences reflect application-specific design parameters. Selection should account for the target operating environment: the original part supports extended low-temperature operation (-40°C), while the substitute operates within 0°C to 70°C boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 5-6605809-5 be used as a direct replacement for ARJM11C7-628-KB-EW2?

A: Yes. Both components share identical connector type, port configuration, application rating, mounting method, and termination approach. The 0.012" (0.30mm) height differential is within typical PCB layout tolerance for through-hole connectors.

Q: What are the key differences between these parts?

A: The substitute includes decoupling capacitance and features a thicker gold contact finish (50.0µin vs. 6.00µin). Operating temperature range differs: the original supports -40°C to 85°C, while the substitute operates 0°C to 70°C. The substitute is an active product with current supply availability.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both ARJM11C7-628-KB-EW2 and 5-6605809-5 are ROHS3 compliant and REACH unaffected.

Q: Does the height difference affect PCB layout?

A: The height variance of 0.012" (0.30mm) is negligible for standard PCB design. Both parts maintain 90° right-angle orientation and identical solder termination footprints.

Q: What is the inventory status of the substitute part?

A: The 5-6605809-5 is in active production with 757 pieces available as new original stock.
