Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-2004-0-3-LP/S-R is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

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

The substitute part 5555140-1 from TE Connectivity AMP Connectors meets all these criteria. Both parts share identical electrical and mechanical specifications for the core connector function, with the substitute offering additional EMI finger shielding and Cat3 rating while maintaining full compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The 5555140-1 from TE Connectivity AMP Connectors is the qualified substitute for the obsolete A-2004-0-3-LP/S-R. Selection is based on the following factors:

Product Status: The original part is obsolete, making the active 5555140-1 the appropriate replacement to ensure continued supply availability and manufacturing support.

Compliance and Certifications: The 5555140-1 carries RoHS compliance certification, providing regulatory advantage for new designs and ongoing production. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Electrical and Mechanical Compatibility: All critical parameters align between the two parts, including connector configuration, orientation, termination method, operating temperature range, contact materials, and finish specifications. The substitute includes enhanced EMI finger shielding and Cat3 rating, which provide additional performance capability without compromising compatibility.

Housing Material Variation: The substitute uses PBT (polybutylene terephthalate) in combination with polyester, compared to the original's polyester with glass fill. Both material compositions support the identical operating temperature range and moisture sensitivity level, ensuring functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 5555140-1 be used as a direct replacement for the A-2004-0-3-LP/S-R in existing designs?

A: Yes. Both connectors share identical specifications for connector type, contact configuration (6p6c), orientation (90° right-angle), mounting method (through-hole solder), shielding, operating temperature range, and contact materials. The 5555140-1 is electrically and mechanically compatible with designs originally specified for the A-2004-0-3-LP/S-R.

Q: What is the difference in shielding between the two parts?

A: The A-2004-0-3-LP/S-R provides standard shielding. The 5555140-1 includes both shielding and an EMI finger, which offers enhanced electromagnetic interference protection. This additional feature does not affect mechanical compatibility or electrical performance in standard applications.

Q: Are there packaging differences between these parts?

A: The A-2004-0-3-LP/S-R packaging is not specified in the available data. The 5555140-1 is supplied in tray packaging. Packaging differences do not affect connector performance or compatibility; they relate only to handling, storage, and logistics.

Q: Does the housing material difference affect performance?

A: No. The A-2004-0-3-LP/S-R uses polyester with glass fill, while the 5555140-1 uses PBT with polyester. Both material compositions support the same operating temperature range (-40°C to 85°C) and moisture sensitivity level (MSL 1, Unlimited). The materials are functionally equivalent for this application.

Q: Is the 5555140-1 RoHS compliant?

A: Yes. The 5555140-1 is RoHS compliant, providing regulatory compliance for applications requiring this certification. The original part's RoHS status is not specified.

Q: What is the Cat3 rating on the 5555140-1?

A: Cat3 (Category 3) is a telecommunications standard rating for structured cabling systems. This rating on the 5555140-1 indicates suitability for voice and data transmission applications up to 16 MHz. This specification does not affect mechanical compatibility with the original design.
