Substitute Part Grouping Explanation

Substitution of the ARJM11B3-577-KB-EW2 is determined by strict equivalence across the following critical parameters:

• 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 solder termination, 90° right-angle orientation
• Shielding & Protection: Shielded construction with integrated LED indicators
• Environmental Compliance: ROHS3 and REACH compliance

The substitute part 0826-1XX1-46-F (Bel Fuse Inc., MagJack® series) meets these core functional requirements. Both connectors share identical connector type, port count, mounting methodology, orientation, termination approach, and application specifications. Height above board measurements are equivalent within manufacturing tolerance (0.535" vs 0.536"). Both maintain shielded construction with matching LED color indicators and gold contact finish.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B3-577-KB-EW2 is classified as Obsolete. The substitute part 0826-1XX1-46-F is classified as Active and maintains full functional and electrical equivalence across all specified parameters. Both components satisfy ROHS3 and REACH compliance requirements, ensuring regulatory alignment for current and future production.

The 0826-1XX1-46-F offers the advantage of active product status, ensuring continued availability and manufacturer support. The operating temperature range differs (0°C ~ 70°C for the substitute versus -40°C ~ 85°C for the original); applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must evaluate this specification against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1XX1-46-F directly replace the ARJM11B3-577-KB-EW2 in existing designs?

A: Yes. Both connectors share identical RJ45 configuration, 8-core jack structure, through-hole solder termination, 90° right-angle orientation, and 10/100/1000 Base-T AutoMDIX support. Physical dimensions are equivalent within manufacturing tolerance. PCB layout compatibility is maintained.

Q: What is the primary difference between these two parts?

A: The ARJM11B3-577-KB-EW2 is Obsolete; the 0826-1XX1-46-F is Active. The substitute has a narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C). The substitute features Board Guide instead of Board Lock and has increased contact finish thickness (50.0µin versus 6.00µin).

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both the ARJM11B3-577-KB-EW2 and 0826-1XX1-46-F are ROHS3 Compliant and REACH Unaffected.

Q: Does the difference in contact finish thickness affect electrical performance?

A: Both parts maintain gold contact finish suitable for 10/100/1000 Base-T applications. The increased thickness in the substitute (50.0µin) provides additional durability for repeated mating cycles.

Q: What is the significance of the Tab Direction difference?

A: The ARJM11B3-577-KB-EW2 has Tab Direction Down; the 0826-1XX1-46-F has Tab Direction Up. This affects mechanical retention orientation on the PCB but does not impact electrical function or compatibility with standard RJ45 cables.
