Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11C7-559-KB-EW2 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

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

Secondary Compliance Parameters:

• RoHS3 Compliance (required)
• MSL Rating: 1 (Unlimited) (required)
• REACH Unaffected status (required)

The substitute part 5-6605809-5 (TRP Connector B.V., MagJack® series) satisfies all primary and secondary criteria, establishing direct functional and electrical equivalence for design replacement and procurement purposes.

Parameter Comparison

Engineering Selection Recommendations

The 5-6605809-5 (TRP Connector B.V., MagJack® series) is qualified as a direct substitute for the obsolete ARJM11C7-559-KB-EW2. Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for current production environments.

Operational Considerations:

The substitute part exhibits a height variance of +0.012" (0.30mm) above the PCB, which falls within typical mechanical tolerance ranges for modular connector applications and does not preclude direct board-level substitution.

The substitute part operates within a narrower temperature range (0°C ~ 70°C) compared to the original part (-40°C ~ 85°C). Design applications requiring operation below 0°C or above 70°C must be evaluated against actual field deployment conditions.

The substitute part provides enhanced contact finish thickness (50.0µin versus 6.00µin), which exceeds the original specification and provides improved durability and contact reliability.

Both components feature identical electrical and functional specifications for 10/100/1000 Base-T Ethernet with AutoMDIX, Board Lock features, and 8-core jack configuration with shielded EMI finger design.

Frequently Asked Questions (FAQ)

Q: Can the 5-6605809-5 be used as a direct replacement for the ARJM11C7-559-KB-EW2 in existing designs?

A: Yes. Both connectors share identical RJ45 configuration, Through Hole mounting, 90° right-angle orientation, solder termination, and 10/100/1000 Base-T AutoMDIX functionality. The mechanical height variance of +0.012" (0.30mm) is within standard PCB layout tolerances and does not require design modification.

Q: What is the primary difference between these two connectors?

A: The primary differences are product status (original is Obsolete; substitute is Active), operating temperature range (original: -40°C ~ 85°C; substitute: 0°C ~ 70°C), and contact finish thickness (original: 6.00µin; substitute: 50.0µin). All electrical and functional parameters remain equivalent.

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

A: No. Both components are ROHS3 Compliant, REACH Unaffected, and carry identical MSL Rating 1 (Unlimited) classifications. Substitution does not introduce regulatory compliance issues.

Q: Does the substitute part require PCB layout modifications?

A: No. The height variance of +0.012" (0.30mm) is negligible for standard PCB design practices. Existing footprints and layouts are compatible without modification.

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

A: The 5-6605809-5 is classified as Active product status with 757 Pcs New Original In Stock, ensuring supply chain availability for production and field replacement applications.

Q: Should temperature range differences affect component selection?

A: The substitute part operates within 0°C ~ 70°C. Applications requiring operation outside this range (particularly below 0°C or above 70°C) must be evaluated against actual deployment conditions. For standard commercial and industrial Ethernet applications, this range is typically sufficient.
