Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11A1-007-AB-CW2 is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Electrical Application: 10/100 Base-T with AutoMDIX support
• Physical Form Factor: Through Hole mounting, 90° right-angle orientation, solder termination
• Signal Integrity: Shielded construction with EMI finger protection, 4 cores per jack
• Mechanical Features: Board lock mechanism, down-facing tab direction
• Contact Properties: Gold finish on contacts
• Environmental Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected

The substitute part A63-113-331P431 meets all these criteria while maintaining Active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The A63-113-331P431 from Mercury United Electronics, Inc. is the qualified substitute for the obsolete ARJM11A1-007-AB-CW2. Selection is based on:

• Functional Equivalence: Identical electrical specifications for 10/100 Base-T networking applications with AutoMDIX capability
• Mechanical Compatibility: Matching form factor, mounting method, and board-level integration parameters
• Compliance Alignment: Both components maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status
• Supply Continuity: Active product status ensures sustained availability and manufacturing support
• Physical Tolerance: Height differential of 0.004" (0.10mm) is within standard PCB assembly tolerances and does not impact functional performance

The increased contact finish thickness (15.0µin vs. 6.00µin) on the substitute part provides enhanced durability and extended contact life without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can A63-113-331P431 be used as a direct replacement for ARJM11A1-007-AB-CW2 in existing designs?

A: Yes. Both components share identical connector type, port configuration, electrical application, mounting method, orientation, and termination approach. The 0.004" height difference is within standard PCB assembly tolerances.

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

A: The A63-113-331P431 features 15.0µin gold plating compared to 6.00µin on the original part. This increased thickness enhances contact durability and wear resistance without altering electrical performance or compatibility.

Q: Are there packaging differences between these parts?

A: The ARJM11A1-007-AB-CW2 packaging is not specified in available data. The A63-113-331P431 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Why is the original part classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The A63-113-331P431 maintains Active status, ensuring continued manufacturing support and supply availability.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 Compliant, carry MSL 1 (Unlimited) rating, and are REACH Unaffected. Operating temperature range is identical at 0°C to 70°C.
