Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-10141 is determined by strict alignment with the following core parameters:

• Connector Type: RJ45 (mandatory match)
• Number of Ports: 1 (mandatory match)
• Applications: 10 Base-T (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Orientation: 90° Angle (Right) (mandatory match)
• Termination: Solder (mandatory match)
• Number of Cores per Jack: 3 (mandatory match)
• Shielding: Shielded, EMI Finger (mandatory match)
• Features: Board Lock (mandatory match)
• Tab Direction: Down (mandatory match)
• Contact Finish: Gold (mandatory match)
• LED Color: Does Not Contain LED (mandatory match)

The ARJ11A-MDSN-MU2 manufactured by Abracon LLC meets all mandatory substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-10141 and ARJ11A-MDSN-MU2 are active production parts meeting all functional and mechanical substitution criteria for 10 Base-T RJ45 through-hole applications.

The ARJ11A-MDSN-MU2 offers ROHS3 compliance, which may be required for applications subject to RoHS regulations. The SI-10141 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts carry identical REACH and ECCN classifications, indicating equivalent regulatory status for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the ARJ11A-MDSN-MU2 be used as a direct replacement for the SI-10141?

A: Yes. Both connectors share identical functional and mechanical specifications including connector type, port configuration, mounting method, orientation, termination style, shielding, and board lock features. They are electrically and mechanically interchangeable for 10 Base-T applications.

Q: What is the difference in contact finish thickness between these parts?

A: The SI-10141 has a contact finish thickness of 50.0µin (1.27µm), while the ARJ11A-MDSN-MU2 has 6.00µin (0.152µm). Both gold finishes meet the functional requirements for 10 Base-T connectivity. The difference reflects different manufacturing specifications but does not affect electrical performance or compatibility.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory requirement, not a functional parameter. The ARJ11A-MDSN-MU2 is ROHS3 compliant, while the SI-10141 is not. Selection between these parts depends on your application's regulatory requirements, not on electrical or mechanical compatibility.

Q: Are the operating temperature ranges different?

A: The SI-10141 does not specify an operating temperature range. The ARJ11A-MDSN-MU2 specifies 0°C ~ 70°C. Both parts are suitable for standard industrial and commercial 10 Base-T applications within this temperature range.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the SI-10141 and ARJ11A-MDSN-MU2 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
