Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARJ11A-MASF-LT2 are identified based on strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10 Base-T
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.545" (13.84mm)
• Shielding: Shielded
• Number of Cores per Jack: 3
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Parts meeting all these specifications are classified as direct substitutes within the ARJ11A series. Variations in part numbering reflect manufacturing or packaging differences that do not affect electrical or mechanical compatibility.

Parameter Comparison
