Substitute Part Grouping Explanation

Substitution of the ARJM11D7-502-AD-ER2-T is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45 (8-core jack configuration)
• Mounting Method: Through-hole PCB termination
• Physical Orientation: 90° right-angle configuration
• Board Height: 0.543" (13.80mm) above PCB surface
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX capability
• Mechanical Features: Shielded construction with board lock mechanism
• Contact Material: Gold plating for signal integrity
• Environmental Compliance: ROHS3 and REACH compliance maintained

The ARJM11D7-502-AB-ER2-T meets all these criteria and is classified as a direct functional equivalent within the ARJM11 series.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-502-AB-ER2-T is the direct substitute for the obsolete ARJM11D7-502-AD-ER2-T. Both parts are manufactured by Abracon LLC within the same ARJM11 series and maintain identical electrical, mechanical, and environmental specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial Ethernet applications. The only functional difference is the LED indicator color configuration: the main part features green-orange LEDs, while the substitute features green-yellow LEDs. This difference does not affect electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ARJM11D7-502-AB-ER2-T be used as a direct replacement for ARJM11D7-502-AD-ER2-T?

A: Yes. Both parts are electrically and mechanically identical RJ45 connectors within the ARJM11 series. They share identical pinout, contact configuration, mounting footprint, and performance specifications for 10/100/1000 Base-T applications.

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

A: The primary difference is LED indicator color. The ARJM11D7-502-AD-ER2-T uses green-orange LEDs, while the ARJM11D7-502-AB-ER2-T uses green-yellow LEDs. This is a cosmetic distinction with no impact on electrical function or signal integrity.

Q: Are the PCB footprints identical?

A: Yes. Both connectors maintain the same 0.543" (13.80mm) height above board, identical through-hole termination pattern, and 90° right-angle orientation. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ARJM11D7-502-AD-ER2-T and ARJM11D7-502-AB-ER2-T are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Why is the main part listed as obsolete?

A: The ARJM11D7-502-AD-ER2-T has been discontinued by Abracon LLC. The ARJM11D7-502-AB-ER2-T remains in active production and serves as the current equivalent for new designs and ongoing procurement.
