Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11A1-502-AD-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: 0.535" (14.69mm)
• Applications: 10/100/1000 Base-T, AutoMDIX
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The ARJM11A1-502-AB-CW2 meets all substitution criteria. Variations in LED color (Green-Orange vs. Green-Yellow) and packaging format (bulk vs. tray) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11A1-502-AB-CW2 is the direct substitute for the obsolete ARJM11A1-502-AD-CW2. Both parts maintain identical electrical and mechanical specifications, including connector type, port configuration, mounting method, orientation, termination style, and board height. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is product status: the substitute part is active and available for procurement, whereas the main part is obsolete. LED color variation (Green-Orange to Green-Yellow) does not affect circuit functionality. Packaging format difference (bulk to tray) is a logistics consideration only and does not impact component performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can ARJM11A1-502-AB-CW2 be used as a direct replacement for ARJM11A1-502-AD-CW2 in existing designs?

A: Yes. Both connectors are electrically and mechanically identical across all critical parameters including connector type, port count, mounting configuration, orientation, termination method, and board height. The substitute part is fully compatible with existing PCB layouts and circuit designs.

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

A: LED color variation (Green-Orange vs. Green-Yellow) is a visual indicator only and does not affect electrical performance, signal integrity, or functional operation of the connector in 10/100/1000 Base-T applications.

Q: Does the packaging format change from bulk to tray affect component compatibility?

A: No. Packaging format is a procurement and handling consideration only. It does not impact the electrical or mechanical properties of the connector itself.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The ARJM11A1-502-AB-CW2 remains in active production and is the recommended source for new procurement.

Q: Are both parts compliant with current regulatory standards?

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

Q: Can these connectors be used interchangeably in high-speed Ethernet applications?

A: Yes. Both connectors support 10/100/1000 Base-T applications with AutoMDIX functionality and are shielded with EMI fingers for signal integrity in Ethernet environments.
