ARJ11C-MCSAT-A-B-5MU2 Equivalent & Substitute Parts

Part Overview

The ARJ11C-MCSAT-A-B-5MU2 is a 1 Port RJ45 Through Hole modular connector manufactured by Abracon LLC, designed for 10/100/1000 Base-T Ethernet applications with AutoMDIX capability. This connector features a 90° right-angle orientation, solder termination, and integrated LED indicators (Green-Yellow). The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements allow for alternative connectors that maintain functional compatibility across core electrical and mechanical parameters while accommodating variations in packaging, inventory availability, or specific manufacturing specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARJ11C-MCSAT-A-B-5MU2 are qualified based on strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100/1000 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• LED Color: Green - Yellow
• Operating Temperature: 0°C ~ 70°C
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

All three substitute parts meet these core requirements. Variations in height above board (within 0.014" tolerance), contact finish thickness, shield material composition, and housing material do not affect functional compatibility for standard 10/100/1000 Base-T Ethernet applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full functional equivalence to the ARJ11C-MCSAT-A-B-5MU2 for 10/100/1000 Base-T Ethernet applications. Selection among these alternatives should be based on:

Product Status & Compliance: All parts are Active in product status with ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment and long-term availability.

Packaging Considerations: The main part is supplied in standard packaging, while all substitutes are available in Tray packaging, which may affect procurement logistics and handling requirements.

Inventory Availability: ARJ11C-MBSAT-A-B-3MU2 (1525 pcs), 0857931006 (1578 pcs), and A60-113-231N432 (1590 pcs) offer comparable stock levels, supporting consistent supply chain planning.

Mechanical Tolerance: Height above board variations range from 0.532" to 0.546", representing a 0.014" tolerance band. This variation is within standard PCB design clearance specifications and does not impact functional performance in typical applications.

Contact Finish Specifications: Contact finish thickness varies across substitutes (6.00µin to 30.0µin). All finishes meet gold plating standards for Ethernet connector applications and provide equivalent electrical performance and durability.

Frequently Asked Questions (FAQ)

Q: Can ARJ11C-MBSAT-A-B-3MU2 be used as a direct replacement for ARJ11C-MCSAT-A-B-5MU2?

A: Yes. Both parts are manufactured by Abracon LLC within the same ARJ11C series, share identical electrical specifications, and differ only in packaging format (Tray vs. standard) and minor height tolerance (0.010" difference). They are functionally equivalent for 10/100/1000 Base-T applications.

Q: What is the significance of the height above board variation between substitutes?

A: Height variations (0.532" to 0.546") reflect manufacturing tolerances within the RJ45 connector standard. These differences do not affect PCB layout compatibility or connector performance, as standard Ethernet jack clearance specifications accommodate this range.

Q: Are there electrical performance differences between the Abracon and Molex substitutes?

A: No. Both manufacturers' parts meet identical RJ45 specifications for 10/100/1000 Base-T applications. Differences in contact material composition (Copper Alloy vs. unspecified) and shield material (Stainless Steel vs. unspecified) do not result in measurable electrical performance variation for standard Ethernet signaling.

Q: Does the contact finish thickness affect connector reliability?

A: Contact finish thickness variations (6.00µin to 30.0µin) are within acceptable ranges for Ethernet connectors. All finishes provide equivalent corrosion resistance and electrical conductivity for standard operating conditions (0°C to 70°C).

Q: Can these parts be mixed in the same design or assembly?

A: Yes. All four parts are mechanically and electrically compatible. Mixed usage is permissible where design flexibility or supply chain optimization requires component sourcing from multiple manufacturers.

Q: What packaging format should be selected for production assembly?

A: Tray packaging (used by all substitutes) is standard for automated pick-and-place assembly. Selection between manufacturers should be based on supplier availability, lead time, and cost considerations rather than technical performance.
