Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11C7-809-AD-EW4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.543" (13.80mm)
• Shielding: Shielded, EMI Finger
• Number of Cores per Jack: 8
• Contact Finish: Gold
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11C7-809-AB-EW2 qualifies as a direct substitute, maintaining identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status transition from obsolete to active, with packaging change from standard to tray format and LED color variation (Green-Yellow vs. Green-Orange).

Parameter Comparison

Engineering Selection Recommendations

The ARJM11C7-809-AB-EW2 is the manufacturer-recommended substitute for the obsolete ARJM11C7-809-AD-EW4. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in 2.5G Base-T applications with AutoMDIX support.

Selection Basis:

• Product Status: The substitute part is active and currently in production, providing assured long-term availability and supply chain stability.
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.
• Electrical Equivalence: Identical connector type, port configuration, core count, and operating temperature range ensure direct functional substitution.
• Mechanical Compatibility: Matching mounting type, orientation, height above board, and termination method enable direct PCB layout compatibility without redesign.

Considerations:

LED color differs between parts (Green-Orange vs. Green-Yellow). If LED color is functionally critical to the application, this distinction must be evaluated against design requirements. Contact finish thickness varies (30.0µin vs. 6.00µin), though both maintain gold finish specification and equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can ARJM11C7-809-AB-EW2 be used as a direct replacement for ARJM11C7-809-AD-EW4 on existing PCBs?

A: Yes. Both parts share identical mechanical and electrical specifications, including mounting type, orientation, height above board, and solder termination. No PCB redesign is required.

Q: What is the significance of the LED color difference?

A: The LED color change from Green-Orange to Green-Yellow is a cosmetic variation. Both configurations provide identical functional status indication for 2.5G Base-T connectivity. Selection depends on whether specific LED color is required by application design or user interface standards.

Q: Are there differences in contact durability between the two parts?

A: Contact finish thickness differs (30.0µin vs. 6.00µin), though both parts specify gold finish. Both maintain equivalent electrical performance and reliability within the stated operating temperature range of -40°C to 85°C.

Q: What packaging format should be specified for production orders?

A: The substitute part is supplied in tray packaging. Confirm tray format compatibility with your assembly process. The original part used standard packaging; verify that tray format meets your procurement and handling requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both ARJM11C7-809-AD-EW4 and ARJM11C7-809-AB-EW2 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for electronic components.

Q: Why is the original part classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of production. The ARJM11C7-809-AB-EW2 represents the active production equivalent, ensuring continued availability for new designs and field service applications.
