Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11A3-516-KB-EW2 is determined by the following critical parameters:

Primary Substitution Criteria:

• 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

The substitute part 2250069-1 (TRP Connector B.V., MagJack® series) meets all primary substitution criteria. Both connectors share identical functional specifications for RJ45 networking applications, mounting configuration, and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 2250069-1 (TRP Connector B.V.) is a direct functional equivalent for the obsolete ARJM11A3-516-KB-EW2. Both connectors satisfy identical electrical and mechanical requirements for 10/100/1000 Base-T Ethernet applications with AutoMDIX support.

Compliance Status:

• Both parts maintain ROHS3 compliance
• Both parts are REACH Unaffected
• Both parts carry EAR99 export classification
• Both parts share identical HTSUS commodity code

Product Status Consideration: The substitute part 2250069-1 maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the original ARJM11A3-516-KB-EW2 is Obsolete. Selection of the active substitute part provides supply chain continuity and access to current manufacturing batches.

Physical Compatibility: Height above board measurements differ by 0.006" (0.16mm), which falls within standard PCB layout tolerances for through-hole connectors and does not impact functional compatibility or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can 2250069-1 be used as a direct replacement for ARJM11A3-516-KB-EW2 in existing designs?

A: Yes. Both connectors share identical RJ45 connector type, port configuration, 10/100/1000 Base-T AutoMDIX functionality, through-hole mounting, 90° right-angle orientation, solder termination, and 8-core jack architecture. Electrical and mechanical compatibility is confirmed across all primary substitution parameters.

Q: What are the differences between these two connectors?

A: The connectors differ in the following non-critical parameters: manufacturer (Abracon LLC vs. TRP Connector B.V.), product series designation (ARJM11 vs. MagJack®), product status (Obsolete vs. Active), LED color configuration, tab direction, contact material specification, operating temperature range, contact finish thickness, housing material, and shield material. These differences do not affect functional compatibility for 10/100/1000 Base-T applications.

Q: Are there any PCB layout considerations when substituting these parts?

A: The height above board differs by 0.006" (0.16mm). This minimal variance is within standard PCB design tolerances for through-hole connectors and does not require PCB layout modifications. Verify mounting hole spacing and clearance dimensions against your specific PCB design.

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

A: Yes. Both connectors are ROHS3 Compliant, REACH Unaffected, classified as EAR99 for export purposes, and share the same HTSUS commodity code (8536.69.4040). Compliance documentation is equivalent for both parts.

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

A: The 2250069-1 maintains Active product status with 896 pieces in current inventory. The original ARJM11A3-516-KB-EW2 is Obsolete, making the substitute part the recommended choice for new procurement and ongoing system support.
