Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARJM11B3-576-KB-EW4 is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45 (mandatory match)
• Number of Ports: 1 (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Orientation: 90° Angle (Right) (mandatory match)
• Termination: Solder (mandatory match)
• Applications: 10/100/1000 Base-T, AutoMDIX (mandatory match)
• Number of Cores per Jack: 8 (mandatory match)
• Shielding: Shielded (mandatory match)
• LED Color: Green, Orange-Yellow (mandatory match)
• RoHS Status: ROHS3 Compliant (mandatory match)

The substitute part 0826-1XX1-46-F from Bel Fuse Inc. meets all mandatory electrical and mechanical parameters. Variations in height above board (0.536" vs 0.535"), contact finish thickness, and operating temperature range are within acceptable engineering tolerances for PCB-level integration.

Parameter Comparison

Engineering Selection Recommendations

The 0826-1XX1-46-F from Bel Fuse Inc. is the qualified substitute for the obsolete ARJM11B3-576-KB-EW4. Both components maintain ROHS3 compliance and EAR99 ECCN classification. The substitute part carries Active product status, ensuring continued availability and supply chain stability.

Selection of the 0826-1XX1-46-F is appropriate for applications operating within the 0°C ~ 70°C temperature range. For applications requiring the extended -40°C ~ 85°C operating range of the original part, alternative solutions must be evaluated against the specified temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1XX1-46-F directly replace the ARJM11B3-576-KB-EW4 in existing designs?

A: Yes, for applications within the 0°C ~ 70°C operating temperature range. Both connectors share identical electrical specifications, mechanical orientation, mounting type, and network performance characteristics (10/100/1000 Base-T, AutoMDIX). PCB layout modifications are not required due to the negligible 0.01" (0.02mm) difference in height above board.

Q: What is the significance of the product status difference?

A: The ARJM11B3-576-KB-EW4 is classified as Obsolete, indicating discontinued manufacturing and limited availability. The 0826-1XX1-46-F maintains Active status, ensuring long-term supply availability and manufacturer support.

Q: Are there compatibility considerations for the LED indicators?

A: Both connectors provide identical LED color configurations (Green, Orange-Yellow) for network status indication. No circuit modifications are required for LED functionality.

Q: How do the contact finish specifications differ?

A: The ARJM11B3-576-KB-EW4 specifies 30.0µin (0.76µm) gold finish thickness, while the 0826-1XX1-46-F specifies 50.0µin (1.27µm). Both finishes provide equivalent electrical performance and corrosion resistance for PCB-level solder termination.

Q: What are the packaging and moisture sensitivity considerations?

A: The ARJM11B3-576-KB-EW4 carries MSL 1 (Unlimited) rating. The 0826-1XX1-46-F is classified as Not Applicable for MSL, indicating no moisture sensitivity constraints. Both components are suitable for standard PCB assembly processes without special handling requirements.
