Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARJ11B-MASBC-LU2 are qualified based on matching the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature: 0°C ~ 70°C
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Two substitute parts meet these criteria: ARJ11B-MASAA-MU2 (Abracon LLC) and A63-113-300P422 (Mercury United Electronics, Inc.). Both maintain functional and electrical equivalence for direct PCB substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance with unlimited MSL rating, ensuring regulatory and environmental compatibility across applications. ARJ11B-MASAA-MU2 is an Abracon LLC variant offering identical electrical and mechanical specifications to the primary part, with matching height above board and contact finish thickness. A63-113-300P422 from Mercury United Electronics, Inc. provides functional equivalence with a 0.014" (0.35mm) reduction in height above board and increased contact finish thickness of 15.0µin, suitable for applications where these dimensional and durability variations are acceptable. Selection should be based on availability, packaging requirements (Tray vs. standard packaging), and manufacturer preference within the design constraints.

Frequently Asked Questions (FAQ)

Q: Can ARJ11B-MASAA-MU2 be used as a direct replacement for ARJ11B-MASBC-LU2?

A: Yes. Both parts are manufactured by Abracon LLC with identical connector type, port configuration, applications, mounting orientation, shielding, and operating temperature range. The primary difference is packaging format (Tray vs. standard).

Q: What is the key difference between A63-113-300P422 and the Abracon parts?

A: A63-113-300P422 is manufactured by Mercury United Electronics, Inc. and maintains all critical electrical and mechanical parameters. The height above board is 0.531" (13.49mm) compared to 0.545" (13.84mm) for Abracon parts, and contact finish thickness is 15.0µin versus 6.00µin. These differences do not affect 10/100 Base-T AutoMDIX functionality.

Q: Are all three parts RoHS3 compliant?

A: Yes. ARJ11B-MASBC-LU2, ARJ11B-MASAA-MU2, and A63-113-300P422 are all ROHS3 Compliant with MSL rating of 1 (Unlimited).

Q: What packaging formats are available?

A: ARJ11B-MASBC-LU2 uses standard packaging. ARJ11B-MASAA-MU2 and A63-113-300P422 are supplied in Tray packaging.

Q: Do all parts support AutoMDIX functionality?

A: Yes. All three parts are specified for 10/100 Base-T AutoMDIX applications.
