Substitute Part Grouping Explanation

The ARJM11A1-007-KB-EW4 can be substituted with the 08B0-1X1T-36-F (Bel Fuse Inc., MagJack® series) based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Number of Rows: 1
• Applications: 10/100 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• LED Color: Green, Orange-Yellow
• Number of Cores per Jack: 4
• Shielding: Shielded, EMI Finger
• Operating Temperature: -40°C ~ 85°C
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8536.69.4040

These parameters establish the substitute as functionally equivalent for PCB integration, electrical performance, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 08B0-1X1T-36-F from Bel Fuse Inc. is the qualified substitute for the obsolete ARJM11A1-007-KB-EW4. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

The substitute maintains identical electrical and mechanical specifications across all critical parameters: RJ45 connector type, 1 port configuration, 10/100 Base-T with AutoMDIX support, through-hole solder termination, 90° right-angle orientation, and dual LED indicators. Physical height variance (0.004" difference) is negligible for PCB layout purposes.

The 08B0-1X1T-36-F carries active product status with established supply chain availability (88,964 units in stock), providing long-term sourcing stability compared to the obsolete original component. Both components are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Frequently Asked Questions (FAQ)

Q: Can the 08B0-1X1T-36-F directly replace the ARJM11A1-007-KB-EW4 in existing designs?

A: Yes. Both connectors share identical connector type (RJ45), port configuration (1 port), application support (10/100 Base-T, AutoMDIX), mounting method (through-hole solder), orientation (90° right-angle), and LED functionality (Green, Orange-Yellow). The 0.004" height difference is within standard PCB layout tolerances.

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

A: The primary differences are product status (obsolete vs. active), contact finish thickness (30.0µin vs. 15.0µin), and manufacturer series designation (ARJM11 vs. MagJack®). The substitute features a board guide instead of board lock and specifies contact material (Copper Alloy) and housing material (PBT), which are not documented for the original part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ARJM11A1-007-KB-EW4 and 08B0-1X1T-36-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the packaging difference?

A: The original part packaging is not specified. The substitute is supplied in Tray packaging, which is standard for production environments.

Q: Is the thinner contact finish on the substitute a concern?

A: No. The 15.0µin (0.38µm) gold finish on the 08B0-1X1T-36-F meets industry standards for RJ45 connectors and provides equivalent contact durability and electrical performance for 10/100 Base-T applications.
