Substitute Part Grouping Explanation

Substitution of the ARJM11A1-502-AB-ER4-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Applications: 10/100/1000 Base-T, AutoMDIX
• Height Above Board: 0.535" (13.59mm)
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Operating Temperature Range: -40°C ~ 85°C
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11A1-502-AB-ER2-T qualifies as a direct substitute based on full alignment with all mandatory parameters. Variations in contact finish thickness do not affect functional compatibility for standard Ethernet applications within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11A1-502-AB-ER2-T is the direct substitute for the obsolete ARJM11A1-502-AB-ER4-T. Selection of the substitute part is supported by the following factors:

Product Status: The ARJM11A1-502-AB-ER2-T maintains Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity compared to the Obsolete status of the main part.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, confirming equivalent regulatory standing for global deployment.

Functional Equivalence: All critical electrical and mechanical parameters align identically, including connector type, port configuration, mounting method, orientation, termination type, operating temperature range, and shielding specifications.

Packaging Consistency: Both parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with standard component handling and assembly processes.

The contact finish thickness difference (30.0µin versus 6.00µin) does not impact functional performance for standard Ethernet applications within the specified operating conditions and does not affect signal integrity or connector reliability.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11A1-502-AB-ER2-T be used as a direct replacement for the ARJM11A1-502-AB-ER4-T in existing designs?

A: Yes. The ARJM11A1-502-AB-ER2-T is a direct substitute. All critical electrical and mechanical parameters are identical, including connector type, port count, mounting method, orientation, termination, operating temperature range, and shielding specifications. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the contact finish thickness difference between these parts?

A: The contact finish thickness difference (30.0µin versus 6.00µin) does not affect functional performance for standard 10/100/1000 Base-T Ethernet applications. Both finishes provide adequate contact durability and signal integrity within the specified operating conditions.

Q: Why is the main part marked as Obsolete?

A: The ARJM11A1-502-AB-ER4-T carries Obsolete status, indicating that the manufacturer has discontinued active production and support. The ARJM11A1-502-AB-ER2-T maintains Active status, providing ongoing availability and manufacturer support.
