Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARJM11A1-007-NN-EW4 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Number of Cores per Jack: 4
• Contact Finish: Gold

The substitute part 08B1-1X1T-06-F (Bel Fuse Inc., MagJack® series) satisfies all mandatory parameters, establishing direct functional equivalence for 10/100 Base-T Ethernet applications requiring through-hole PCB mounting with right-angle orientation and solder termination.

Parameter Comparison

Engineering Selection Recommendations

The 08B1-1X1T-06-F represents a direct functional substitute for the obsolete ARJM11A1-007-NN-EW4. Both components meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing and deployment.

The substitute part maintains active product status with Bel Fuse Inc., ensuring ongoing availability and supply chain continuity. Physical dimensions are equivalent within tolerance (height differential of 0.004"), and all electrical and mechanical parameters align with the original specification for 10/100 Base-T Ethernet applications.

The contact finish thickness differential (30.0µin versus 15.0µin) does not affect functional compatibility for the specified application, as both exceed minimum contact durability requirements for solder-terminated RJ45 connectors in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the 08B1-1X1T-06-F be used as a direct replacement for the ARJM11A1-007-NN-EW4?

A: Yes. Both components share identical connector type, port configuration, applications, mounting method, orientation, termination, shielding, and core count. The substitute part is functionally equivalent for 10/100 Base-T Ethernet implementations.

Q: What is the physical compatibility between these two parts?

A: Height above board measurements differ by 0.004" (0.10mm), which is within standard PCB layout tolerance. Both parts maintain 90° right-angle orientation and through-hole solder termination, ensuring mechanical compatibility with existing PCB designs.

Q: Are there regulatory compliance differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution in applications subject to these standards.

Q: Why is the original part obsolete?

A: The ARJM11A1-007-NN-EW4 has been discontinued by Abracon LLC. The 08B1-1X1T-06-F maintains active production status and is the recommended equivalent for new designs and legacy system support.

Q: Does the contact finish thickness affect performance?

A: Contact finish thickness (30.0µin versus 15.0µin) does not impact electrical performance or reliability for standard 10/100 Base-T applications. Both finishes provide adequate durability for solder-terminated connections in specified operating environments.
