Substitute Part Grouping Explanation
Substitution eligibility for the A-2004-2-3-LP/S-R is determined by strict alignment with the following critical parameters:
- Connector Type & Configuration: Must be a jack-type modular connector with 8p8c (RJ45/Ethernet) contact arrangement
- Mechanical Orientation: Must maintain 90° right-angle orientation to ensure PCB layout compatibility
- Mounting & Termination: Must support through-hole mounting with solder termination
- Shielding: Must provide electromagnetic shielding equivalent to the original design
- Contact Properties: Phosphor bronze with gold finish (50.0µin minimum) ensures signal integrity and corrosion resistance
- Housing Material: PBT construction provides mechanical durability and thermal stability
- Operating Temperature: Must support -40°C to 85°C range for industrial and commercial applications
- Functional Features: Board lock and panel stops are required for mechanical retention and alignment
The substitute part 5555153-1 (TE Connectivity AMP Connectors) meets all these criteria and is classified as an MFR (Manufacturer) Recommended equivalent.

Engineering Selection Recommendations
The 5555153-1 (TE Connectivity AMP Connectors) is the designated MFR-recommended substitute for the obsolete A-2004-2-3-LP/S-R. Selection of this alternative is supported by the following engineering factors:
- Product Status: The original part is obsolete, while 5555153-1 maintains active production status, ensuring long-term availability and supply chain continuity
- Compliance & Certifications: 5555153-1 is RoHS Compliant, meeting current environmental and regulatory requirements for new designs and system upgrades
- Electrical & Mechanical Equivalence: All critical parameters—contact configuration, orientation, termination method, shielding, contact materials, and operating temperature range—are identical or functionally equivalent
- Housing Material Compatibility: Both PBT glass-filled and PBT polyester formulations provide equivalent mechanical durability and thermal stability for the specified operating range
- Functional Features: Identical board lock and panel stops ensure mechanical compatibility with existing PCB designs and mounting structures
- Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) rating, indicating no moisture-related handling restrictions
The 5555153-1 is suitable for direct substitution in new procurements, system maintenance, and field replacements where the A-2004-2-3-LP/S-R is no longer available.
Frequently Asked Questions (FAQ)
Q: Can the 5555153-1 be used as a direct replacement for the A-2004-2-3-LP/S-R in existing designs?
A: Yes. The 5555153-1 meets all critical electrical and mechanical parameters required for direct substitution, including connector type, contact configuration, orientation, mounting method, termination, shielding, contact materials, and operating temperature range. No design modifications are required.
Q: What is the difference between the housing materials (PBT Glass Filled vs. PBT Polyester)?
A: Both materials are polybutylene terephthalate (PBT) formulations that provide equivalent mechanical strength, thermal stability, and durability within the specified operating temperature range (-40°C to 85°C). The glass-filled variant in the original part and the polyester variant in the substitute are functionally interchangeable for this application.
Q: Why is the original part listed as obsolete?
A: The A-2004-2-3-LP/S-R is no longer manufactured by Assmann WSW Components. The 5555153-1 from TE Connectivity is the active, manufacturer-recommended alternative that maintains full functional and electrical equivalence.
Q: Does the 5555153-1 have any compliance advantages over the original part?
A: Yes. The 5555153-1 is RoHS Compliant, meeting current environmental regulations for electronic components. This is particularly important for new system designs, upgrades, and applications subject to regulatory compliance requirements.
Q: Are there any packaging or inventory considerations when switching to the 5555153-1?
A: The 5555153-1 is supplied in Tray packaging, whereas the original part packaging is not specified. Verify that tray packaging is compatible with your assembly and handling processes. The 5555153-1 has 3,722 units in stock, ensuring adequate availability for procurement.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution is determined by alignment with: connector type (jack, modular), contact configuration (8p8c/RJ45), orientation (90° right-angle), mounting type (through-hole), termination method (solder), shielding (shielded), contact material (phosphor bronze with gold finish), housing material (PBT), operating temperature range (-40°C to 85°C), and functional features (board lock, panel stops).
