Substitute Part Grouping Explanation

Substitution of the ARJM11A1-007-AD-CW2 is determined by strict alignment of 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
• Mechanical Compatibility: Board lock feature, down-facing tab direction, 4-core jack configuration
• Environmental & Compliance: Operating temperature range 0°C to 70°C, ROHS3 compliance, MSL 1 rating

The substitute part A63-113-331P431 from Mercury United Electronics, Inc. meets all these criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The A63-113-331P431 is the qualified substitute for the obsolete ARJM11A1-007-AD-CW2. Selection is based on:

• Functional Equivalence: Identical electrical specifications for 10/100 Base-T networking with AutoMDIX capability
• Physical Compatibility: Matching form factor, mounting method, and board-level integration parameters with negligible height variance (0.004")
• Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental performance
• Manufacturing Status: The substitute is an active product with established supply chain availability, addressing the obsolescence of the original component
• Certification Alignment: Both components share identical ECCN and HTSUS classifications, maintaining regulatory consistency

Frequently Asked Questions (FAQ)

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

A: Yes. The substitute maintains identical connector type, port configuration, electrical application, mounting method, orientation, and termination approach. The 0.004" height variance is within standard PCB design tolerances and does not affect mechanical or electrical performance.

Q: Are there differences in LED color between the two connectors?

A: Yes. The ARJM11A1-007-AD-CW2 features Green-Orange LEDs, while the A63-113-331P431 features Green-Yellow LEDs. Both indicate identical operational states and do not affect electrical functionality.

Q: What is the significance of the product status difference?

A: The ARJM11A1-007-AD-CW2 is obsolete and no longer manufactured. The A63-113-331P431 is an active product with ongoing manufacturing support, ensuring long-term availability for new production runs and system maintenance.

Q: Are the contact finish specifications equivalent?

A: Both connectors use gold contact finish. The ARJM11A1-007-AD-CW2 specifies 6.00µin thickness, while the A63-113-331P431 specifies 15.0µin thickness. The substitute provides enhanced contact durability with thicker gold plating, maintaining electrical performance across the operating temperature range.

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

A: Yes. Both components are ROHS3 compliant, REACH unaffected, carry MSL 1 rating, and operate across the identical temperature range of 0°C to 70°C.
