Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11D-MASG-B-A-FMU2 is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through-hole, 90° right-angle
• Electrical Application: 10/100 Base-T with AutoMDIX support
• Termination Method: Solder-based PCB attachment
• Shielding & EMI Protection: Shielded construction with EMI finger
• Mechanical Features: Board lock mechanism
• Regulatory Compliance: ROHS3 and REACH status

The identified substitute part A63-113-213N491 meets all these criteria, enabling direct functional replacement in equivalent circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11D-MASG-B-A-FMU2 and A63-113-213N491 are active production parts with equivalent regulatory compliance. The ARJ11D-MASG-B-A-FMU2 is manufactured by Abracon LLC, while the A63-113-213N491 is manufactured by Mercury United Electronics, Inc. Both connectors satisfy ROHS3 and REACH requirements, with identical ECCN and HTSUS classifications.

The mechanical height differential of 0.39mm (13.84mm versus 13.45mm) falls within standard PCB layout tolerances for 90° right-angle connectors and does not affect functional compatibility. Both parts feature identical electrical specifications for 10/100 Base-T AutoMDIX applications, gold-plated contacts, and board lock mechanisms.

Selection between these parts should be based on supply availability, packaging format (Abracon standard packaging versus Mercury United tray packaging), and established supplier relationships within your procurement workflow.

Frequently Asked Questions (FAQ)

Q: Can A63-113-213N491 be used as a direct replacement for ARJ11D-MASG-B-A-FMU2 on existing PCBs?

A: Yes. Both connectors share identical mounting type (through-hole), orientation (90° right-angle), and footprint compatibility. The 0.39mm height difference is within standard mechanical tolerances for this connector category and does not require PCB redesign.

Q: Are there electrical performance differences between these two parts?

A: No. Both connectors support identical 10/100 Base-T and AutoMDIX specifications, with equivalent shielding, EMI protection, and contact materials (gold finish). Operating temperature ranges and moisture sensitivity levels are identical.

Q: What is the difference in packaging between these parts?

A: ARJ11D-MASG-B-A-FMU2 uses standard Abracon packaging, while A63-113-213N491 is supplied in tray packaging by Mercury United Electronics. Packaging format does not affect connector performance or compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Are there any design considerations when switching between these manufacturers?

A: No design changes are required. Both parts are functionally equivalent for 10/100 Base-T Ethernet applications. Verify supplier documentation for any specific handling or storage requirements related to MSL Level 1 classification.
