Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11D-MASE-A-B-GMU2 is determined by strict equivalence across the following critical parameters:

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

Qualified substitutes maintain these electrical and mechanical specifications. Minor variations in height above board (within manufacturing tolerance), contact finish thickness, and packaging format do not affect functional compatibility in standard PCB applications.

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance with REACH Unaffected designation. Selection between ARJ11D-MASE-A-B-GMU2, ARJ11D-MASE-A-B-EMU2, and A63-113-231N435 is based on packaging format and inventory availability.

ARJ11D-MASE-A-B-EMU2 is the manufacturer-recommended substitute, offering identical electrical and mechanical specifications with Tray packaging. This variant is preferred for high-volume production environments requiring standardized packaging formats.

A63-113-231N435 from Mercury United Electronics, Inc. provides cross-manufacturer compatibility with equivalent functional performance. The 0.014" (0.35mm) height differential and increased contact finish thickness (15.0µin versus 6.00µin) remain within acceptable tolerances for standard PCB assembly processes. This option is suitable when supply from the primary manufacturer is constrained.

Frequently Asked Questions (FAQ)

Q: Can ARJ11D-MASE-A-B-EMU2 be used as a direct replacement for ARJ11D-MASE-A-B-GMU2?

A: Yes. Both parts are manufactured by Abracon LLC with identical electrical and mechanical specifications. The only difference is packaging format (Tray versus unspecified). No design or assembly modifications are required.

Q: Is A63-113-231N435 electrically compatible with ARJ11D-MASE-A-B-GMU2?

A: Yes. Both connectors meet 10/100 Base-T and AutoMDIX specifications with identical pin configurations, shielding, and termination methods. The cross-manufacturer design ensures functional equivalence in standard Ethernet applications.

Q: Does the 0.014" height difference between ARJ11D-MASE-A-B-GMU2 and A63-113-231N435 affect PCB layout?

A: No. The 0.531" height of A63-113-231N435 versus 0.545" for ARJ11D-MASE-A-B-GMU2 is within standard manufacturing tolerances and does not require PCB redesign for typical applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. ARJ11D-MASE-A-B-GMU2, ARJ11D-MASE-A-B-EMU2, and A63-113-231N435 are all ROHS3 Compliant with REACH Unaffected status.

Q: What is the difference in contact finish thickness, and does it matter?

A: ARJ11D-MASE-A-B-GMU2 and ARJ11D-MASE-A-B-EMU2 have 6.00µin finish thickness, while A63-113-231N435 has 15.0µin. Both thicknesses provide adequate corrosion resistance and electrical conductivity for 10/100 Base-T applications. The thicker finish on A63-113-231N435 may offer extended contact life in high-cycle mating environments.

Q: Which part should be selected for new designs?

A: ARJ11D-MASE-A-B-GMU2 or ARJ11D-MASE-A-B-EMU2 are recommended for new designs, as both are from the primary manufacturer with established supply chains. A63-113-231N435 is suitable as a secondary source or when primary options are unavailable.
