Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-2004-1-3-LP/S-R is determined by strict alignment of the following parameters:

• Connector type (Jack)
• Contact configuration (6p6c RJ11/RJ12/RJ14/RJ25 compatible)
• Mechanical orientation (90° right-angle)
• Mounting method (through-hole solder termination)
• Shielding requirement (shielded construction)
• Contact material and finish specifications (phosphor bronze with gold plating)
• Housing material (PBT-based)
• Operating temperature range (-40°C to 85°C minimum)
• Mechanical features (board lock and panel stops)

The substitute part 5555140-1 from TE Connectivity AMP Connectors meets all these criteria, with the addition of EMI finger shielding and Cat3 rating, providing enhanced electromagnetic interference protection while maintaining full mechanical and electrical compatibility.
