Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-634-AD-CW4 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: 0.543" (13.80mm)
• Number of Cores per Jack: 8
• Shielding: Shielded
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

The ARJM11D7-502-AB-CW2 meets all substitution criteria as an active product within the same ARJM11 series, maintaining identical mechanical, electrical, and environmental specifications. Variations in LED color and contact finish thickness do not affect functional compatibility in 10/100/1000 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-502-AB-CW2 is the qualified substitute for the obsolete ARJM11D7-634-AD-CW4. Selection is based on:

• Active product status ensuring ongoing availability and supply chain continuity
• Identical mechanical footprint and board-level integration requirements
• Full compliance with ROHS3 and REACH regulatory requirements
• Equivalent electrical performance for 10/100/1000 Base-T applications with AutoMDIX support
• Maintained MSL rating of 1 (Unlimited) for storage and handling

The substitute part maintains all functional and environmental specifications required for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11D7-502-AB-CW2 be used as a direct replacement for the ARJM11D7-634-AD-CW4?

A: Yes. Both connectors share identical mechanical dimensions, electrical specifications, mounting requirements, and operating temperature ranges. The substitute is an active product within the same series.

Q: What is the difference between the LED colors in these two parts?

A: The main part features Green-Orange LEDs while the substitute features Green-Yellow LEDs. LED color selection does not affect electrical performance or network functionality in 10/100/1000 Base-T applications.

Q: Does the contact finish thickness difference impact compatibility?

A: No. Both parts use gold contact finish. The thickness variation (30.0µin versus 6.00µin) does not affect electrical conductivity, signal integrity, or mechanical durability for the specified applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ARJM11D7-634-AD-CW4 and ARJM11D7-502-AB-CW2 are ROHS3 compliant and REACH unaffected.

Q: What is the MSL rating for these connectors?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Why is the original part listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The ARJM11D7-502-AB-CW2 provides functional equivalence as an active alternative within the ARJM11 series.
