ARJ11D-MASH-B-A-FLU2 Equivalent & Substitute Parts

Part Overview

The ARJ11D-MASH-B-A-FLU2 is a 1 Port RJ45 Through Hole modular connector manufactured by Abracon LLC, designed for 10/100 Base-T Ethernet applications with AutoMDIX capability. This connector features a 90° right-angle orientation, solder termination, and integrated LED indicators (Yellow-Green). The product is currently Active with 1065 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits functional equivalents that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the ARJ11D-MASH-B-A-FLU2 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
• Shielding & EMI Protection: Shielded with EMI finger
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

The substitute part A63-113-213N491 (Mercury United Electronics, Inc.) meets all these criteria. Both parts share identical functional specifications for connector type, port count, mounting method, orientation, application support, and regulatory compliance. Mechanical dimensions vary slightly (height above board: 0.545" vs. 0.530"), which remains within acceptable tolerance for standard PCB layouts. Contact finish thickness differs (6.00µin vs. 15.0µin), with the substitute providing enhanced durability through thicker gold plating.

Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11D-MASH-B-A-FLU2 and A63-113-213N491 are Active products with full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). Selection between these parts should be based on:

Primary Part (ARJ11D-MASH-B-A-FLU2): Use when Abracon LLC supply chain is preferred or when the standard contact finish thickness (6.00µin) is specified in design documentation.

Substitute Part (A63-113-213N491): Use when Mercury United Electronics supply is more readily available, when enhanced contact durability is required through thicker gold plating (15.0µin), or when the slightly reduced height above board (0.530" vs. 0.545") provides design advantage. Both parts carry identical electrical performance and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can A63-113-213N491 be used as a direct replacement for ARJ11D-MASH-B-A-FLU2 in existing designs?

A: Yes. Both connectors share identical RJ45 port configuration, 90° right-angle orientation, through-hole solder termination, 10/100 Base-T AutoMDIX support, and shielding specifications. The 0.015" (0.39mm) difference in height above board and thicker contact plating on the substitute do not affect functional compatibility in standard PCB layouts.

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

A: The substitute part features 15.0µin gold plating compared to 6.00µin on the primary part. Thicker plating provides extended contact durability and improved resistance to wear during mating cycles, beneficial in high-cycle applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across 0°C to 70°C, with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What packaging differences exist between these parts?

A: The primary part (ARJ11D-MASH-B-A-FLU2) packaging is not specified in available data. The substitute part (A63-113-213N491) is supplied in Tray packaging. Verify packaging requirements with your procurement specifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8536.69.4040).
