Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11B3-576-KB-EW2 is determined by the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through hole, 90° right-angle
• Electrical Specification: 10/100/1000 Base-T with AutoMDIX support
• Physical Interface: 8-core jack with solder termination
• Shielding & Protection: Shielded construction with gold contact finish
• Regulatory Compliance: ROHS3 and REACH requirements

The substitute part 0826-1XX1-46-F from Bel Fuse Inc. meets these core substitution criteria. Both parts share identical connector type, port count, mounting method, orientation, termination style, and network application specifications. Both are ROHS3 compliant and REACH unaffected.

Parameter Comparison

Engineering Selection Recommendations

The 0826-1XX1-46-F from Bel Fuse Inc. is the qualified substitute for the obsolete ARJM11B3-576-KB-EW2. Both parts satisfy identical electrical and mechanical requirements for 10/100/1000 Base-T Ethernet applications with AutoMDIX functionality. The substitute part maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The primary distinction is product status: the original part is obsolete while the substitute is active, ensuring continued availability and manufacturing support. Physical dimensions are equivalent within tolerance (height differential of 0.001" / 0.02mm). Both employ shielded construction with gold-plated contacts suitable for industrial and commercial networking applications.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1XX1-46-F directly replace the ARJM11B3-576-KB-EW2 in existing designs?

A: Yes. Both connectors share identical connector type (RJ45), port configuration (1 port), mounting method (through hole), orientation (90° right-angle), termination style (solder), and network specifications (10/100/1000 Base-T, AutoMDIX). Physical height above board differs by 0.001 inches, which is within standard PCB layout tolerances.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Abracon vs. Bel Fuse), product status (obsolete vs. active), operating temperature range (ARJM11B3: -40°C to 85°C vs. 0826-1XX1-46-F: 0°C to 70°C), and contact finish thickness (ARJM11B3: 6.00µin vs. 0826-1XX1-46-F: 50.0µin). The substitute part features thicker gold plating and a narrower operating temperature range.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ARJM11B3-576-KB-EW2 and 0826-1XX1-46-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of the operating temperature range difference?

A: The ARJM11B3-576-KB-EW2 operates from -40°C to 85°C, while the 0826-1XX1-46-F operates from 0°C to 70°C. For applications requiring extended low-temperature operation below 0°C or sustained operation above 70°C, the original part specification must be retained. For standard commercial and industrial environments (0°C to 70°C), the substitute part is suitable.

Q: Does the thicker gold plating on the substitute part affect compatibility?

A: No. The thicker gold plating (50.0µin vs. 6.00µin) on the 0826-1XX1-46-F provides enhanced contact durability and corrosion resistance. This is a performance improvement that does not affect electrical or mechanical compatibility.

Q: Are there alternative substitute parts available?

A: The substitute part 0826-1XX1-46-F includes cross-reference to JK0-0136NL. Verification of this alternative should be conducted against the same substitution criteria outlined in this document.
