Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-2004-1-4-LP/S-R is determined by strict alignment of the following critical parameters:

• Connector type (Jack)
• Contact configuration (6p6c RJ11/RJ12/RJ14/RJ25 compatibility)
• Mounting method (Through Hole)
• Orientation (90° right-angle)
• Termination type (Solder)
• Shielding requirement (Shielded)
• Port and row configuration (1 port, 1 row)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Housing material (PBT-based)
• Operating temperature range (-40°C ~ 85°C)
• Mechanical features (Board Lock, Panel Stops)

The substitute part 5555140-1 from TE Connectivity AMP Connectors meets all these criteria, with the addition of EMI Finger shielding enhancement and Cat3 rating, making it a direct functional equivalent.

Engineering Selection Recommendations

The 5555140-1 from TE Connectivity AMP Connectors is the qualified substitute for the obsolete A-2004-1-4-LP/S-R. Selection is based on the following factors:

• All critical electrical and mechanical parameters align with the original specification
• The substitute maintains active product status, ensuring long-term availability and supply chain continuity
• RoHS compliance of the substitute part supports regulatory requirements for new designs
• Enhanced EMI Finger shielding in the substitute provides equivalent or superior electromagnetic interference protection
• Cat3 rating of the substitute meets or exceeds the performance requirements of the original part
• Both parts share identical operating temperature ranges and contact material specifications
• Packaging format (Tray) of the substitute is suitable for production environments

Frequently Asked Questions (FAQ)

Q: Can the 5555140-1 be used as a direct replacement for A-2004-1-4-LP/S-R in existing designs?

A: Yes. Both connectors share identical contact configurations (6p6c), mounting methods (through-hole solder), orientations (90° right-angle), and operating temperature ranges (-40°C ~ 85°C). The substitute meets all functional and mechanical requirements of the original part.

Q: What is the difference between the shielding specifications?

A: The original part specifies basic shielding, while the substitute includes EMI Finger shielding with Cat3 rating. This enhancement provides improved electromagnetic interference protection without affecting mechanical or electrical compatibility.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in Tray packaging, which is standard for production environments and does not affect connector functionality or performance.

Q: Does the RoHS compliance of the substitute affect compatibility?

A: No. RoHS compliance of the 5555140-1 indicates adherence to environmental and material restrictions, making it suitable for applications requiring regulatory compliance. It does not alter electrical or mechanical compatibility with the original specification.

Q: Are the contact finish specifications equivalent?

A: Both parts use gold-plated phosphor bronze contacts. The original specifies 6.00µin (0.152µm) thickness, while the substitute specifies 50.0µin (1.27µm). The substitute's thicker gold plating provides enhanced durability and contact reliability without affecting compatibility.
