• Connector Type & Port Configuration: RJ45, single port, 8-core jack
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
• Physical Form Factor: Through-hole mounting, 90° right-angle orientation, solder termination
• Signal Integrity: Shielded construction with integrated LED indicators
• Regulatory Compliance: ROHS3 and REACH compliance maintained

The substitute part 0826-1XX1-46-F from Bel Fuse Inc. meets these core functional and mechanical requirements while offering Active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The 0826-1XX1-46-F from Bel Fuse Inc. is the qualified substitute for the obsolete ARJM11D7-577-KB-EW4. Both components maintain ROHS3 and REACH compliance, ensuring regulatory alignment for current and future production. The substitute part carries Active product status, providing assured long-term availability and supply chain stability compared to the Obsolete designation of the original component.

Physical dimensions are equivalent within manufacturing tolerances (height differential of 0.007" / 0.19mm is negligible for PCB layout). Electrical performance, connector type, port configuration, and application support are identical across both parts. The substitute part is suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1XX1-46-F be used as a direct replacement for the ARJM11D7-577-KB-EW4?

A: Yes. Both components share identical connector type (RJ45), port configuration (1 port, 8-core), mounting method (through-hole solder), orientation (90° right-angle), and electrical performance (10/100/1000 Base-T, AutoMDIX). Physical dimensions are equivalent within standard manufacturing tolerances.

Q: What is the primary reason for substitution?

A: The ARJM11D7-577-KB-EW4 is classified as Obsolete. The 0826-1XX1-46-F maintains Active product status, ensuring continued availability and supply chain support for new designs and production runs.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory standing.

Q: What is the height difference between these connectors?

A: The ARJM11D7-577-KB-EW4 measures 0.543" (13.80mm) above board, while the 0826-1XX1-46-F measures 0.536" (13.61mm). This 0.007" (0.19mm) difference is within standard PCB layout tolerances and does not affect mechanical or electrical compatibility.

Q: Are LED indicators identical on both parts?

A: Yes. Both components feature Green and Orange-Yellow LED indicators for network status monitoring.
