Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11E-MCSA-A-B-FM2 is determined by strict alignment with the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through-hole, 90° right-angle
• Electrical Application: 10/100/1000 Base-TX with AutoMDIX support
• Shielding & EMI Protection: Shielded construction with EMI finger
• Termination Method: Solder termination
• Core Count: 8 cores per jack
• Compliance: ROHS3 compliant, REACH unaffected, EAR99 classification
• Environmental Rating: Operating temperature 0°C to 70°C, MSL 1

The substitute parts listed below maintain these core parameters within acceptable mechanical and electrical tolerances for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full compliance with ROHS3, REACH, and EAR99 classifications. Selection between ARJ11E-MCSA-A-B-FM2, ARJ11E-MBSA-A-B-EM2, and A60-113-331P432 is determined by packaging requirements and application-specific electrical specifications.

ARJ11E-MCSA-A-B-FM2 and ARJ11E-MBSA-A-B-EM2 are functionally equivalent Abracon LLC parts with identical electrical and mechanical parameters. The primary difference is packaging format. Both support 10/100/1000 Base-TX with AutoMDIX and maintain identical height above board (0.545"), contact finish thickness (6.00µin), and all core electrical specifications.

A60-113-331P432 from Mercury United Electronics, Inc. is compatible for 10/100/1000 Base-T applications with AutoMDIX. This part exhibits a marginally reduced height above board (0.535" versus 0.545") and increased contact finish thickness (15.0µin versus 6.00µin). These dimensional and material variations remain within acceptable tolerances for direct substitution in through-hole RJ45 applications.

Frequently Asked Questions (FAQ)

Q: Can ARJ11E-MBSA-A-B-EM2 directly replace ARJ11E-MCSA-A-B-FM2?

A: Yes. Both parts are manufactured by Abracon LLC and maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The difference is packaging format (tray versus original packaging). Direct board-level substitution is supported.

Q: Is A60-113-331P432 compatible with the same PCB footprint?

A: Yes. A60-113-331P432 maintains the same through-hole RJ45 connector footprint, orientation (90° right-angle), and termination method (solder). The height above board difference (0.535" versus 0.545") is 0.010 inches, which is within standard PCB design tolerances for right-angle connectors. Mechanical compatibility is confirmed.

Q: What is the difference between Base-TX and Base-T applications?

A: Both designations refer to 10/100/1000 Mbps Ethernet standards. The ARJ11E-MCSA-A-B-FM2 and ARJ11E-MBSA-A-B-EM2 are specified for Base-TX, while A60-113-331P432 is specified for Base-T. Both support AutoMDIX functionality and are electrically compatible for standard Ethernet applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. ARJ11E-MCSA-A-B-FM2, ARJ11E-MBSA-A-B-EM2, and A60-113-331P432 are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: What is the significance of contact finish thickness variation?

A: ARJ11E-MCSA-A-B-FM2 and ARJ11E-MBSA-A-B-EM2 have 6.00µin (0.152µm) gold contact finish thickness, while A60-113-331P432 has 15.0µin (0.38µm). Both thicknesses provide adequate contact durability and electrical conductivity for 10/100/1000 Mbps Ethernet applications. The thicker finish on A60-113-331P432 offers extended contact life in high-cycle mating environments.

Q: Can these connectors be used interchangeably in production?

A: Yes, within the constraints of packaging and supply chain requirements. All three parts meet identical electrical performance criteria, operating temperature ranges (0°C to 70°C), and compliance standards. Selection should be based on packaging availability, lead time, and specific procurement specifications.
