Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11B1-008-AD-ER2-T is determined by strict equivalence across the following critical parameters:

Connector Type, Number of Ports, Mounting Type, Orientation, Termination Method, Height Above Board, Number of Cores per Jack, Shielding Configuration, Board Lock Feature, Tab Direction, Contact Finish, Operating Temperature Range, RoHS Compliance, and Moisture Sensitivity Level.

The ARJM11B1-009-AB-ER2-T qualifies as a direct substitute because it maintains identical specifications across all these parameters. The only variance is LED color (Green-Orange vs. Green-Yellow), which does not affect electrical or mechanical compatibility. The substitute part is currently in active production status, providing supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-009-AB-ER2-T is the recommended substitute for the obsolete ARJM11B1-008-AD-ER2-T. Both parts maintain identical electrical and mechanical specifications, including RoHS3 compliance, REACH unaffected status, and EAR99 export classification. The substitute part is in active production, ensuring supply availability and long-term support. The LED color difference does not impact functional performance or circuit compatibility. For applications requiring the original LED color specification, design review may be necessary; however, from a technical substitution standpoint, the parts are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11B1-009-AB-ER2-T be used as a direct replacement for the ARJM11B1-008-AD-ER2-T in existing designs?

A: Yes. The substitute part maintains identical specifications across all electrical, mechanical, and environmental parameters. PCB footprints, mounting hole patterns, solder pad configurations, and connector pin assignments are identical. No design modifications are required.

Q: What is the difference between these two parts?

A: The only difference is the LED indicator color. The original part features Green-Orange LEDs, while the substitute features Green-Yellow LEDs. All other specifications, including connector type, port configuration, mounting method, shielding, temperature range, and compliance certifications, are identical.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. They share the same HTSUS code and carry identical moisture sensitivity levels.

Q: Is the substitute part available in production quantities?

A: Yes. The ARJM11B1-009-AB-ER2-T is currently in active production status with documented inventory availability.

Q: Will the LED color change affect circuit functionality?

A: No. LED color is a visual indicator only and does not affect electrical performance, signal integrity, or network communication capability. Both parts support 10/100 Base-T Ethernet with AutoMDIX functionality identically.
