Equivalent & Substitute Parts for A-2004-2-3-LP-N

Part Overview

The A-2004-2-3-LP-N is a modular jack connector manufactured by Assmann WSW Components, designed for 8p8c (RJ45, Ethernet) applications. This through-hole mounted connector features a 90° right-angle orientation with unshielded construction and solder termination. The component is actively produced and maintains full compliance with ROHS3 and REACH standards. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-2004-2-3-LP-N are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Mounting Method: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Shielding Configuration: Unshielded
• Operating Temperature Range: -40°C ~ 85°C
• Contact Material: Phosphor Bronze with Gold finish

All identified substitute parts match these core parameters. Variations in housing material, contact finish thickness specifications, and series designations do not affect electrical or mechanical substitutability when these primary criteria are maintained.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compliance with regulatory requirements applicable to the original component. The 0855035001 (Molex, Series 85503) and RJE031880110 (Amphenol ICC, Series RJE03) are actively produced components with established supply availability. Selection between the original part and substitutes should be based on procurement lead times, inventory availability, and cost considerations, as all three components satisfy the electrical and mechanical requirements for 8p8c modular jack applications with through-hole solder termination and 90° right-angle orientation.

Frequently Asked Questions (FAQ)

Q: Can the 0855035001 (Molex) be used as a direct replacement for the A-2004-2-3-LP-N?

A: Yes. Both components share identical connector type, contact configuration (8p8c RJ45), mounting method (through-hole), orientation (90° right-angle), termination (solder), and shielding (unshielded). Operating temperature ranges and compliance certifications are equivalent.

Q: What is the difference between the housing materials used in these parts?

A: The A-2004-2-3-LP-N uses Polyester Glass Filled housing, the 0855035001 uses Liquid Crystal Polymer (LCP) Glass Filled housing, and the RJE031880110 uses Thermoplastic housing. These material variations do not affect electrical performance or mechanical compatibility in standard applications.

Q: Are there differences in contact finish specifications?

A: Contact finish material (Gold) is consistent across all three parts. Contact finish thickness varies: A-2004-2-3-LP-N specifies 50.0µin (1.27µm), 0855035001 specifies Flash, and RJE031880110 specifies 6.00µin (0.152µm). These variations remain within acceptable parameters for 8p8c modular jack applications.

Q: Do all substitute parts meet the same compliance standards?

A: All three parts are ROHS compliant. The A-2004-2-3-LP-N and 0855035001 are ROHS3 compliant. The RJE031880110 is RoHS compliant. All parts are REACH Unaffected or REACH Compliant and classified as EAR99 for export control purposes.

Q: What is the significance of the Cat5e rating on the Molex part?

A: The 0855035001 includes a Cat5e rating designation, indicating qualification for Category 5e Ethernet applications. This does not restrict its use in other 8p8c applications and represents an additional performance specification beyond the base connector requirements.

Q: Are there any packaging or inventory considerations?

A: All parts are supplied in Tray packaging. Current inventory levels are: A-2004-2-3-LP-N (1099 pcs), 0855035001 (1909 pcs), and RJE031880110 (2877 pcs). Availability should be confirmed with the supplier for production requirements.
