ARJM11D7-809-AD-ER2-T Equivalent & Substitute Parts

Part Overview

The ARJM11D7-809-AD-ER2-T is a 1 Port RJ45 Through Hole 2.5G Base-T connector with AutoMDIX functionality, manufactured by Abracon LLC. This component is classified as Obsolete, indicating discontinuation from active production. The connector features a 90° right-angle orientation, solder termination, and integrated board lock mechanism suitable for PCB-mounted applications requiring high-speed Ethernet connectivity.

Due to its obsolete status, identifying equivalent substitute parts is essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain identical electrical performance, mechanical compatibility, and environmental specifications to ensure seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-809-AD-ER2-T is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector Type: RJ45
• Number of Ports: 1
• Number of Rows: 1
• Applications: 2.5G Base-T, AutoMDIX
• Number of Cores per Jack: 8
• Shielding: Shielded
• Contact Finish: Gold
• Contact Finish Thickness: 6.00µin (0.152µm)

Mechanical Compatibility:

• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.543" (13.80mm)
• Features: Board Lock
• Tab Direction: Up

Environmental & Compliance:

• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all parameters listed above. Variations in LED color do not affect electrical or mechanical compatibility and are therefore permissible in substitute selection.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-809-AB-ER2-T is the primary substitute for the obsolete ARJM11D7-809-AD-ER2-T. This recommendation is based on the following factors:

Product Status: The substitute part maintains Active status, ensuring continued availability and manufacturing support from Abracon LLC. This addresses the obsolescence constraint of the original part.

Compliance Equivalence: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new production and long-term supply chain stability.

Electrical & Mechanical Parity: The substitute part matches all critical electrical parameters (2.5G Base-T, AutoMDIX, 8-core shielded configuration) and mechanical specifications (Through Hole, 90° right-angle orientation, 0.543" height, board lock feature, solder termination).

LED Indicator Variation: The only difference between the main part and substitute is the LED color (Green-Orange versus Green-Yellow). This variation does not impact electrical performance or mechanical compatibility and is acceptable for direct substitution in applications where LED color is not a design-critical parameter.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11D7-809-AB-ER2-T be used as a direct replacement for the ARJM11D7-809-AD-ER2-T?

A: Yes. The substitute part is electrically and mechanically equivalent across all critical parameters, including connector type, port configuration, 2.5G Base-T AutoMDIX functionality, mounting method, orientation, and environmental specifications. The only difference is LED color, which does not affect functionality.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of the substitute part ensures ongoing manufacturing availability, supply chain continuity, and technical support from the manufacturer. This eliminates the risk of future unavailability associated with obsolete components.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental requirements are fully equivalent.

Q: Does the LED color difference affect electrical performance or signal integrity?

A: No. LED color is a visual indicator only and does not impact electrical performance, signal integrity, or 2.5G Base-T transmission characteristics. The substitute part maintains identical electrical specifications.

Q: Are the mechanical dimensions and mounting characteristics identical?

A: Yes. Both parts feature identical Through Hole mounting, 90° right-angle orientation, 0.543" (13.80mm) height above board, board lock feature, and solder termination. PCB layout and mechanical integration are fully compatible.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold contact finish with 6.00µin (0.152µm) thickness, ensuring equivalent electrical conductivity and corrosion resistance for reliable 2.5G Base-T connectivity.

Q: Are there any temperature or environmental operating range differences?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and maintain equivalent environmental performance specifications.
