Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARJM11D7-576-KB-EW2 is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port, 8-core jack
• Electrical Application: 10/100/1000 Base-T with AutoMDIX support
• Physical Form Factor: Through-hole mounting, 90° right-angle orientation, solder termination
• Shielding & Protection: Shielded design with integrated LED indicators (green and orange-yellow)
• Contact & Finish Specifications: Gold-plated contacts for reliable signal transmission
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part 0826-1XX1-46-F from Bel Fuse Inc. meets all critical substitution criteria within the allowed parameter tolerance range. Height above board variance (13.80mm vs. 13.61mm) and operating temperature range differences are within acceptable mechanical and thermal design margins for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The 0826-1XX1-46-F from Bel Fuse Inc. is an active product with current manufacturing status, providing supply chain continuity for applications previously served by the obsolete ARJM11D7-576-KB-EW2. Both connectors maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial Ethernet applications.

The primary design consideration is the operating temperature range differential. The original ARJM11D7-576-KB-EW2 supports -40°C to 85°C operation, while the 0826-1XX1-46-F operates within 0°C to 70°C. For applications requiring extended low-temperature performance below 0°C or sustained operation above 70°C, thermal design validation is necessary. The mechanical height variance of 0.19mm is negligible for standard PCB layout and does not impact connector interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1XX1-46-F directly replace the ARJM11D7-576-KB-EW2 in existing designs?

A: Yes, for applications operating within the 0°C to 70°C temperature range. The connectors share identical RJ45 port configuration, 90° right-angle orientation, through-hole solder termination, and 10/100/1000 Base-T AutoMDIX functionality. PCB footprint compatibility requires verification of the 0.19mm height difference, though this is typically accommodated within standard design tolerances.

Q: What are the key electrical differences between these connectors?

A: Both connectors provide equivalent electrical performance for Gigabit Ethernet applications. Contact finish thickness differs (6.00µin vs. 50.0µin), with the substitute part featuring thicker gold plating, which enhances contact durability and signal integrity over extended operational life.

Q: Are there compliance or certification differences?

A: Both connectors maintain ROHS3 compliance and REACH unaffected status. No compliance gaps exist between the original and substitute part for regulated markets.

Q: What is the primary limitation of the 0826-1XX1-46-F as a substitute?

A: The operating temperature range is narrower (0°C to 70°C vs. -40°C to 85°C). Applications requiring operation below 0°C or sustained exposure above 70°C must evaluate alternative solutions or implement thermal management strategies.

Q: Are there additional cross-reference options listed for the substitute part?

A: The 0826-1XX1-46-F includes cross-reference designation JK0-0136NL for component identification and sourcing purposes.
