Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11B1-577-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)
• Number of Cores per Jack: 8
• Shielding: Shielded
• Features: Board Lock
• Tab Direction: Down
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11B1-502-AB-CW2 meets all substitution criteria. The only variance is the LED color indicator (Green-Orange vs. Green-Yellow), which does not affect electrical or mechanical compatibility for 10/100/1000 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-502-AB-CW2 is the direct functional equivalent for the obsolete ARJM11B1-577-AD-CW2. Both connectors are manufactured by Abracon LLC within the ARJM11 series and maintain identical electrical, mechanical, and thermal specifications. The substitute part is currently in active production status, ensuring supply chain continuity and long-term availability.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial Ethernet applications. The operating temperature range of 0°C to 70°C and moisture sensitivity level of 1 (unlimited) are equivalent across both parts, supporting deployment in standard environmental conditions.

The LED color difference (Green-Orange vs. Green-Yellow) represents the only variance and does not impact electrical performance, signal integrity, or mechanical fit. This variance is a visual indicator only and does not affect 10/100/1000 Base-T AutoMDIX functionality.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11B1-502-AB-CW2 be used as a direct replacement for the ARJM11B1-577-AD-CW2 in existing PCB designs?

A: Yes. Both connectors share identical mechanical dimensions, pin configurations, solder pad layouts, and electrical specifications. No PCB redesign is required for substitution.

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

A: The LED color serves as a visual status indicator only. The Green-Orange and Green-Yellow variants indicate different link/activity status representations but do not affect electrical compatibility or signal transmission for 10/100/1000 Base-T applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the ARJM11B1-577-AD-CW2 and ARJM11B1-502-AB-CW2 operate within the 0°C to 70°C temperature range with identical thermal characteristics.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements during storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both connectors are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What is the through-hole pin configuration for these RJ45 connectors?

A: Both connectors feature 8 cores per jack, supporting standard RJ45 Ethernet pinout for 10/100/1000 Base-T applications with AutoMDIX capability.
