Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARJM11C7-516-AB-CW2 is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Electrical Specification: 10/100/1000 Base-T with AutoMDIX support
• Physical Form Factor: Through hole mounting, 90° right-angle orientation, solder termination
• Mechanical Compatibility: Height above board, tab direction (up), board lock feature
• Signal Integrity: 8-core jack with shielded construction and EMI finger protection
• Environmental & Regulatory: Operating temperature range 0°C to 70°C, ROHS3 compliance, REACH unaffected status

The substitute part A60-113-231N432 (Mercury United Electronics, Inc.) meets all these criteria, with minor variations in contact finish thickness and shield material composition that do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The A60-113-231N432 is the qualified substitute for the obsolete ARJM11C7-516-AB-CW2. Selection is based on:

• Functional Equivalence: Identical electrical specifications for 10/100/1000 Base-T Ethernet with AutoMDIX
• Physical Compatibility: Matching through-hole mounting, 90° orientation, and board lock features with negligible height variance (0.011" difference)
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status
• Product Availability: The substitute part is in active production status with confirmed inventory (1590 pcs), ensuring long-term supply chain continuity
• Environmental Rating: Identical operating temperature range and moisture sensitivity classification

Frequently Asked Questions (FAQ)

Q: Can the A60-113-231N432 be used as a direct replacement for the ARJM11C7-516-AB-CW2 in existing PCB designs?

A: Yes. Both connectors share identical mounting type (through hole), orientation (90° right angle), and electrical specifications (10/100/1000 Base-T, AutoMDIX). The 0.011" height difference (13.80mm vs 14.61mm) is within typical PCB layout tolerances and does not affect mechanical or electrical performance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical (MSL 1, Unlimited). Operating temperature ranges match (0°C to 70°C).

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

A: The A60-113-231N432 features a thicker gold contact finish (15.0µin vs 6.00µin). This provides enhanced durability and contact reliability, representing an improvement over the original part specification.

Q: Why is the original ARJM11C7-516-AB-CW2 marked as obsolete?

A: Obsolescence indicates the part is no longer manufactured by Abracon LLC. The A60-113-231N432 provides functional and mechanical equivalence for new designs and replacement applications.

Q: Are packaging differences relevant to the substitution?

A: The substitute part is supplied in Tray packaging. Packaging format does not affect connector performance or PCB integration. Verify packaging requirements for your procurement and assembly processes.
