Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11C7-634-AB-CW2 is determined by strict alignment with the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through Hole, 90° right-angle
• Electrical Specifications: 10/100/1000 Base-T with AutoMDIX support, 8-core jack
• Mechanical Interface: Solder termination, board lock feature
• Environmental Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected
• Signaling & Indicators: Green-Yellow LED color

The substitute part A60-113-331P411 (Mercury United Electronics, Inc.) meets all mandatory substitution criteria. Both components share identical connector type, port count, mounting method, orientation, termination type, application support, core count, shielding configuration, board lock feature, operating temperature range, and regulatory compliance status. Minor variations in physical height (0.543" vs. 0.535"), tab direction, contact material composition, and contact finish thickness do not preclude functional equivalence in standard PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

The A60-113-331P411 is the qualified substitute for the obsolete ARJM11C7-634-AB-CW2. Selection is based on:

• Product Status Alignment: The substitute maintains Active status, ensuring continued availability and manufacturing support, whereas the original component is Obsolete.
• Regulatory Compliance: Both components achieve ROHS3 compliance and REACH Unaffected status, meeting current environmental and hazardous substance restrictions.
• Functional Equivalence: Identical electrical and mechanical specifications for 10/100/1000 Base-T Ethernet connectivity with AutoMDIX support ensure drop-in compatibility in standard PCB designs.
• Supply Chain Continuity: The substitute part is currently in stock (1103 Pcs) with established manufacturing continuity, supporting both new production and field replacement requirements.

The minor dimensional variation in height (0.008" / 0.21mm difference) and tab direction orientation do not impact electrical performance or standard PCB assembly processes. The increased contact finish thickness (15.0µin vs. 6.00µin) on the substitute part provides enhanced durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can the A60-113-331P411 be used as a direct replacement for the ARJM11C7-634-AB-CW2 in existing PCB designs?

A: Yes. Both components share identical connector type, port configuration, mounting method, orientation, termination type, and electrical specifications for 10/100/1000 Base-T applications. The minor height difference (0.008") and tab direction variation do not affect electrical performance or standard through-hole assembly compatibility.

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

A: The A60-113-331P411 features 15.0µin gold plating compared to 6.00µin on the original part. This increased thickness provides enhanced contact durability and resistance to wear during mating cycles, supporting extended field life without compromising electrical performance.

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

A: No. Both components are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share identical HTSUS coding (8536.69.4040). Regulatory and environmental compliance status is equivalent.

Q: What is the difference in tab direction, and does it affect PCB layout?

A: The ARJM11C7-634-AB-CW2 features an upward tab direction, while the A60-113-331P411 has a downward tab direction. This is a mechanical orientation difference that may require verification against specific PCB footprint designs. Standard RJ45 footprints typically accommodate both orientations without modification.

Q: Is the A60-113-331P411 available in the same packaging as the original part?

A: The substitute is supplied in Tray packaging. Original packaging information for the ARJM11C7-634-AB-CW2 was not specified. Confirm packaging requirements with procurement specifications for your application.

Q: What is the inventory status for the substitute part?

A: The A60-113-331P411 is currently in stock with 1103 Pcs available as New Original inventory, ensuring immediate availability for production and replacement requirements.
