Key Parameters

Substitute Part Grouping Explanation

Substitution of the 520249-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters:

• Connector type (Jack)
• Contact count and configuration (4p4c RJ9/RJ10/RJ22)
• Shielding classification (Unshielded)
• Category rating (Cat3)
• Contact material and finish specifications (Phosphor Bronze, Gold 50.0µin)

Mechanical Parameters:

• Mounting method (Through Hole)
• Orientation (90° Right Angle)
• Termination type (Solder)
• Housing material (Polyester)
• Mechanical features (Board Lock, Panel Stops)
• Tab direction (Down)

Environmental Parameters:

• Operating temperature range (-40°C ~ 85°C)
• Moisture sensitivity level (MSL 1)

Parts meeting all these criteria are classified as direct functional equivalents and may be substituted without design modification.
