ARJ11C-MCSAT-A-B-6MU2 Equivalent & Substitute Parts

Part Overview

The ARJ11C-MCSAT-A-B-6MU2 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 shielded connector features a 90° right-angle orientation, board lock mechanism, and dual LED indicators (Green-Yellow). The part is currently active in production with 708 units in stock. Substitute parts may be required due to inventory constraints, packaging preferences, or specific mechanical clearance requirements in PCB layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11C-MCSAT-A-B-6MU2 is determined by strict alignment of the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port, 8-core jack
• Mounting & Orientation: Through hole, 90° right-angle orientation
• Electrical Application: 10/100/1000 Base-T with AutoMDIX support
• Shielding & EMI Protection: Shielded construction with EMI finger
• Mechanical Features: Board lock mechanism, dual LED indicators
• Termination Method: Solder termination
• Compliance: ROHS3 compliant, REACH unaffected, MSL 1 rating

All three substitute parts meet these core criteria. Variations in height above board (0.532" to 0.546"), contact material composition, contact finish thickness, and shield material do not affect functional interchangeability for standard 10/100/1000 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the ARJ11C-MCSAT-A-B-6MU2 for 10/100/1000 Base-T Ethernet applications. Selection should be based on the following factors:

Abracon LLC ARJ11C-MBSAT-A-B-3MU2: Same manufacturer as the primary part, ensuring design continuity and supply chain consistency. Available in tray packaging with higher inventory (1525 units). Height above board is 0.010" lower than the primary part, suitable for space-constrained layouts.

Molex 0857931006: Cross-manufacturer alternative with the highest inventory availability (1578 units). Meets all electrical and mechanical specifications. Contact finish thickness is 30.0µin, providing enhanced durability compared to the primary part's 6.00µin specification.

Mercury United Electronics A60-113-231N432: Third-source option with maximum inventory (1590 units). Lowest height above board at 0.532", optimal for applications with minimal vertical clearance. Contact material is phosphor bronze with 15.0µin finish thickness.

All parts maintain ROHS3 compliance, unlimited MSL rating, and identical operating temperature ranges. Selection among substitutes should prioritize PCB layout constraints, packaging requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can ARJ11C-MBSAT-A-B-3MU2 be used as a direct replacement for ARJ11C-MCSAT-A-B-6MU2?

A: Yes. Both parts are manufactured by Abracon LLC within the same ARJ11C series, share identical electrical specifications for 10/100/1000 Base-T applications, and feature the same connector type, port configuration, mounting method, and shielding. The primary difference is packaging format (tray vs. bulk) and a 0.010" reduction in height above board.

Q: What is the significance of the height above board variation (0.532" to 0.546")?

A: Height above board affects PCB layout clearance. The 0.014" maximum variation across all four parts is negligible for most applications but may be critical in designs with restricted vertical space. Verify clearance requirements against your specific PCB assembly before selection.

Q: Are the contact material differences between substitutes functionally significant?

A: Contact material composition (copper alloy, phosphor bronze) and finish thickness variations (6.00µin to 30.0µin) do not affect electrical performance for standard Ethernet applications. These differences relate to contact durability and mating cycle life, not signal integrity or impedance characteristics.

Q: Which substitute offers the best inventory availability?

A: Mercury United Electronics A60-113-231N432 has the highest stock level at 1590 units, followed by Molex 0857931006 at 1578 units, and Abracon LLC ARJ11C-MBSAT-A-B-3MU2 at 1525 units.

Q: Do all substitutes maintain the same compliance certifications?

A: Yes. All four parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) ratings. Compliance status is identical across the primary part and all substitutes.

Q: Is tray packaging compatible with bulk packaging in mixed production runs?

A: Tray and bulk packaging formats do not affect component functionality or electrical performance. Packaging selection should be based on assembly process requirements, storage conditions, and handling procedures specific to your manufacturing environment.
