Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARJM11B1-007-AD-ER4-T is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port, 4 cores per jack
• Electrical Application: 10/100 Base-T with AutoMDIX support
• Mechanical Compatibility: Through hole mounting, 90° right-angle orientation, 0.535" (14.69mm) height above board, down-facing tab direction
• Termination & Assembly: Solder termination with board lock feature
• Environmental & Compliance: Operating temperature range -40°C ~ 85°C, ROHS3 compliance, MSL 1 rating

The ARJM11B1-009-AB-ER2-T meets all critical substitution criteria. Differences in LED color (Green-Yellow vs. Green-Orange) and contact finish thickness (6.00µin vs. 30.0µin) do not affect functional compatibility or electrical performance in 10/100 Base-T applications. The substitute part is currently in active production status, ensuring supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-009-AB-ER2-T is the direct functional equivalent for the obsolete ARJM11B1-007-AD-ER4-T. Both parts are manufactured by Abracon LLC within the ARJM11 series and maintain identical electrical, mechanical, and environmental specifications for 10/100 Base-T Ethernet applications.

Selection of the substitute part is supported by:

• Product Status: The substitute is in active production, ensuring long-term supply availability and manufacturing consistency
• Compliance Alignment: Both parts maintain ROHS3 compliance and identical environmental ratings (MSL 1, -40°C ~ 85°C operating range)
• Mechanical Interchangeability: Identical footprint, height, orientation, and mounting characteristics enable direct PCB layout compatibility
• Electrical Equivalence: Identical port configuration, shielding, and 10/100 Base-T AutoMDIX functionality

The substitute part is suitable for direct replacement in new designs and production transitions from the obsolete model.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11B1-009-AB-ER2-T be used as a direct replacement on existing PCBs designed for the ARJM11B1-007-AD-ER4-T?

A: Yes. Both connectors share identical mechanical dimensions, footprint, mounting type (through hole), orientation (90° right-angle), and height above board (0.535"). No PCB layout modifications are required.

Q: What is the significance of the different LED colors between the two parts?

A: LED color differences (Green-Orange vs. Green-Yellow) are cosmetic and do not affect electrical performance or functional compatibility. Both indicate identical link and activity status in 10/100 Base-T applications.

Q: Does the difference in contact finish thickness affect electrical performance?

A: No. Both parts use gold contact finish and operate identically in 10/100 Base-T Ethernet applications. Contact finish thickness variations do not impact signal integrity or electrical characteristics within the specified operating parameters.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the inventory status of the substitute part?

A: The ARJM11B1-009-AB-ER2-T has 927 pieces in stock as new original inventory, supporting immediate procurement for production requirements.
