Mandatory Matching Parameters:

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

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

The substitute part 5-6605809-5 (TRP Connector B.V., MagJack® series) satisfies all mandatory matching parameters and compliance requirements, qualifying it as a direct functional equivalent for the obsolete ARJM11C7-516-KB-EW2.

Parameter Comparison

Engineering Selection Recommendations

The 5-6605809-5 (TRP Connector B.V., MagJack® series) is the qualified substitute for the obsolete ARJM11C7-516-KB-EW2. Selection is based on the following engineering criteria:

Functional Equivalence: Both connectors meet identical electrical and mechanical specifications for 10/100/1000 Base-T Ethernet applications, including RJ45 configuration, 8-core jack design, shielded EMI construction, and AutoMDIX support.

Compliance Alignment: Both components maintain ROHS3 compliance, MSL Level 1 rating, and identical trade classification (ECCN: EAR99, HTSUS: 8536.69.4040), ensuring regulatory continuity.

Supply Chain Status: The substitute part is classified as Active with confirmed inventory availability (757 Pcs), providing reliable sourcing for production and field service requirements.

Design Considerations: The substitute exhibits minor dimensional and thermal variations. The height above board increases by 0.012" (0.30mm), and the operating temperature range narrows to 0°C ~ 70°C. These variations are within typical PCB layout tolerances and standard industrial operating conditions. The contact finish thickness is substantially increased (50.0µin vs. 6.00µin), providing enhanced durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can the 5-6605809-5 be used as a direct replacement for the ARJM11C7-516-KB-EW2 in existing designs?

A: Yes. Both connectors share identical functional specifications for RJ45 Through Hole 10/100/1000 Base-T applications. The 0.012" height variation and narrower operating temperature range of the substitute are within standard design tolerances for most applications. PCB layout verification is recommended for designs with tight vertical clearance constraints.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Height above board: ARJM11C7-516-KB-EW2 is 0.543" versus 5-6605809-5 at 0.555"; (2) Operating temperature: ARJM11C7-516-KB-EW2 operates -40°C ~ 85°C versus 5-6605809-5 at 0°C ~ 70°C; (3) Contact finish thickness: ARJM11C7-516-KB-EW2 has 6.00µin versus 5-6605809-5 at 50.0µin. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both connectors maintain ROHS3 compliance, MSL Level 1 rating, and identical regulatory classifications. Substitution does not introduce compliance risks.

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

A: The 5-6605809-5 is currently Active with 757 Pcs of new original stock available, ensuring reliable supply for production and field replacement applications.

Q: Does the substitute part include the same LED indicators?

A: The substitute part includes LED indicators with different color specifications: Green and Yellow-Green versus the original Green and Orange-Yellow. Both configurations provide visual status indication for network connectivity and activity.
