Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-809-JA-CW2 is determined by strict equivalence across the following critical 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)
• Number of Cores per Jack: 8
• Shielding: Shielded
• Features: Board Lock
• Tab Direction: Up
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11D7-809-KB-CW2 meets all substitution criteria. Variations in LED color indicators (Green, Orange-Yellow versus Green, Yellow-Green) do not affect electrical or mechanical compatibility and remain within the functional scope of the connector series.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-809-KB-CW2 is the direct substitute for the obsolete ARJM11D7-809-JA-CW2. Both components are manufactured by Abracon LLC within the ARJM11 series and maintain identical electrical, mechanical, and compliance specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

The only functional difference is the LED color indicator configuration. The substitute part features Green and Orange-Yellow LEDs compared to the original Green and Yellow-Green combination. This variation does not impact connector performance, signal integrity, or mechanical compatibility in 2.5G Base-T AutoMDIX applications.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11D7-809-KB-CW2 be used as a direct replacement for the ARJM11D7-809-JA-CW2?

A: Yes. Both connectors are electrically and mechanically equivalent. All critical parameters including connector type, port count, mounting configuration, termination method, board height, core count, shielding, and operating temperature range are identical. The substitute part is currently in Active production status.

Q: What is the significance of the LED color difference between these two parts?

A: The LED color variation (Green, Orange-Yellow versus Green, Yellow-Green) is a cosmetic and functional indicator difference only. It does not affect electrical performance, signal transmission, or mechanical compatibility. LED color selection is typically application-specific for visual status indication purposes.

Q: Are there any compliance or certification differences between the main part and substitute?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code. Regulatory and environmental compliance requirements are fully satisfied by the substitute component.

Q: What is the MSL rating, and does it affect storage or handling?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling procedures apply without special environmental controls.

Q: Are there any PCB layout or footprint considerations when substituting this connector?

A: No. The substitute part maintains identical through-hole mounting configuration, 90° right-angle orientation, 0.543" (13.80mm) board height, and up-facing tab direction. PCB layouts designed for the original part require no modification.
