• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Height Above Board: 0.543" (13.80mm)
• Termination: Solder
• Shielding: Shielded
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

The substitute part ARJM11D7-104-KB-CW2 maintains identical specifications across all these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-104-KB-CW2 is the direct substitute for the obsolete ARJM11D7-104-JA-CW2. Both parts are manufactured by Abracon LLC within the ARJM11 series and maintain identical electrical, mechanical, and environmental specifications. The substitute part is currently in Active product status, ensuring long-term availability and supply chain continuity.

Both parts comply with ROHS3 regulations, carry MSL Rating 1 (Unlimited moisture sensitivity), maintain REACH Unaffected status, and are classified under ECCN EAR99. The only distinction between the two parts is the LED color configuration: the main part features Green and Yellow-Green LEDs, while the substitute features Green and Orange-Yellow LEDs. This difference does not affect functional compatibility for 10/100 Base-T Ethernet applications with AutoMDIX and Power over Ethernet (PoE) support.

Frequently Asked Questions (FAQ)

Q: Can ARJM11D7-104-KB-CW2 be used as a direct replacement for ARJM11D7-104-JA-CW2?

A: Yes. Both connectors share identical specifications for connector type, port configuration, mounting method, orientation, height, termination, shielding, board lock feature, contact finish, operating temperature range, and compliance certifications. The parts are mechanically and electrically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary difference is LED color indication. ARJM11D7-104-JA-CW2 uses Green and Yellow-Green LEDs, while ARJM11D7-104-KB-CW2 uses Green and Orange-Yellow LEDs. Both indicate link and activity status in 10/100 Base-T networks identically.

Q: Why is the original part marked as Obsolete?

A: The ARJM11D7-104-JA-CW2 has reached end-of-life status. The ARJM11D7-104-KB-CW2 remains in Active production, providing continued availability and support for equivalent functionality.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, MSL Rating 1, and EAR99 ECCN classification.

Q: What applications are supported by these connectors?

A: Both connectors support 10/100 Base-T Ethernet, AutoMDIX, and Power over Ethernet (PoE) applications with Through Hole solder termination and board lock retention.
