ARJ11E-MCSB-A-B-GM2 Equivalent & Substitute Parts

Part Overview

The ARJ11E-MCSB-A-B-GM2 is a 1-port RJ45 modular connector manufactured by Abracon LLC, designed for 10/100/1000 Base-TX Ethernet applications with AutoMDIX support. This through-hole connector features a 90° right-angle orientation, shielded design with EMI finger protection, and board lock functionality. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when they maintain compatibility across critical electrical and mechanical parameters including connector type, port configuration, mounting method, orientation, termination style, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11E-MCSB-A-B-GM2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Number of Rows: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Tab Direction: Down
• Operating Temperature Range: 0°C ~ 70°C
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variations:

• Manufacturer identity (different OEM)
• Packaging format (Tray vs. other formats)
• Height Above Board (within mechanical tolerance for PCB mounting)
• Contact Finish Thickness (different plating specifications)
• Contact Material composition (when not specified in main part)
• Shield Material and Housing Material (when not specified in main part)
• Specific application designation (Base-TX vs. Base-T, both supporting 10/100/1000 Ethernet)

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the ARJ11E-MCSB-A-B-GM2 across all critical electrical and mechanical parameters. Selection between alternatives is based on the following factors:

ARJ11E-MBSA-A-B-EM2 (Abracon LLC): This substitute is manufactured by the same OEM as the main part and maintains identical specifications including height above board and contact finish thickness. Packaging is supplied in Tray format. This option provides continuity with the original manufacturer while meeting all compliance requirements (ROHS3, REACH Unaffected, EAR99).

A60-113-331P432 (Mercury United Electronics, Inc.): This substitute is manufactured by an alternative OEM and features a slightly reduced height above board (0.535" vs. 0.545") and increased contact finish thickness (15.0µin vs. 6.00µin). Both dimensions remain within acceptable mechanical tolerances for through-hole PCB mounting. Packaging is supplied in Tray format. This option meets all compliance requirements (ROHS3, REACH Unaffected, EAR99) and provides supply diversification.

All three parts are active products with current inventory availability and identical regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can ARJ11E-MBSA-A-B-EM2 be used as a direct replacement for ARJ11E-MCSB-A-B-GM2?

A: Yes. Both parts are manufactured by Abracon LLC and share identical specifications for connector type, port configuration, mounting method, orientation, termination, operating temperature, shielding, and compliance status. The primary difference is packaging format (Tray vs. original packaging).

Q: What is the significance of the height difference between ARJ11E-MCSB-A-B-GM2 and A60-113-331P432?

A: The height above board differs by 0.010" (0.25mm), with A60-113-331P432 measuring 0.535" compared to 0.545" for the main part. This variation is within standard mechanical tolerances for through-hole RJ45 connectors and does not affect electrical performance or PCB compatibility in standard applications.

Q: Does the increased contact finish thickness on A60-113-331P432 affect performance?

A: No. Both contact finish specifications (6.00µin and 15.0µin) provide adequate gold plating for reliable electrical contact and corrosion resistance. The increased thickness on A60-113-331P432 offers enhanced durability in high-cycle mating applications.

Q: Are all three parts suitable for 10/100/1000 Base-TX Ethernet applications?

A: Yes. All three parts support 10/100/1000 Base-TX with AutoMDIX functionality. A60-113-331P432 is designated as 10/100/1000 Base-T, which is functionally equivalent for this application category.

Q: What is the difference between packaging formats, and does it affect component selection?

A: The main part ARJ11E-MCSB-A-B-GM2 is supplied in standard packaging, while both substitutes (ARJ11E-MBSA-A-B-EM2 and A60-113-331P432) are supplied in Tray format. Packaging format does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 Compliant with REACH Unaffected status and EAR99 export classification, meeting current environmental and regulatory requirements.
