Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0855080001 is determined by the following critical parameters:

• Connector type (Jack) and contact configuration (8p8c RJ45)
• Mounting method (Through Hole) and orientation (Vertical)
• Shielding requirement (Shielded)
• Contact material composition (Phosphor Bronze)
• Contact finish specification (Gold plating)
• Operating temperature compatibility (-40°C minimum, 80°C minimum upper limit)
• Regulatory compliance (RoHS3 Compliant)

The identified substitute parts maintain these core electrical and mechanical parameters, enabling direct functional replacement in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

Molex 0855085001 is the primary direct substitute for the obsolete Molex 0855080001. Both components are manufactured by Molex, share identical connector configuration and contact specifications, and maintain the same solder termination method. The 0855085001 is currently in active production status with significantly higher inventory availability (22,642 units in stock versus 1,050 units for the original part). The operating temperature upper limit increases from 80°C to 85°C, providing enhanced thermal margin. Housing material differs (Liquid Crystal Polymer with glass fill versus Polyester with glass fill), and contact finish thickness specification changes from 50.0µin to Flash plating, both acceptable variations within RoHS3 compliance. Packaging is supplied in Tray format.

TE Connectivity 6116202-1 serves as a cross-manufacturer alternative when Molex supply is constrained. This component maintains 8p8c RJ45 configuration, vertical shielded orientation, and phosphor bronze gold-plated contacts. The termination method differs (Press-Fit versus Solder), requiring PCB design modification to accommodate the alternative contact style. Operating temperature range extends to 85°C. Housing material is thermoplastic construction. The component is RoHS Compliant and supplied in Tube packaging. This option is suitable for new designs where termination method flexibility exists.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0855085001 directly replace the Molex 0855080001 without PCB modification?

A: Yes. Both components feature identical 8p8c RJ45 jack configuration, vertical through-hole solder termination, and shielded design. Mechanical and electrical compatibility is maintained. Housing material and contact finish thickness variations do not affect functional performance in Cat5e applications.

Q: What is the primary difference between the Molex 0855085001 and TE Connectivity 6116202-1?

A: The termination method differs. The Molex 0855085001 uses solder termination compatible with standard through-hole PCB assembly, while the TE Connectivity 6116202-1 employs press-fit termination requiring modified PCB pad design and assembly process. Both maintain electrical performance for 8p8c RJ45 applications.

Q: Are there temperature rating differences that affect application suitability?

A: The original Molex 0855080001 operates to 80°C maximum. Both substitute parts extend the upper operating limit to 85°C, providing additional thermal margin. This enhancement does not restrict application scope and supports operation in higher ambient temperature environments.

Q: What packaging formats are available for the substitute parts?

A: The Molex 0855085001 is supplied in Tray packaging. The TE Connectivity 6116202-1 is supplied in Tube packaging. Packaging selection may influence procurement logistics and assembly line integration requirements.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. The Molex 0855085001 maintains ROHS3 Compliant status identical to the original part. The TE Connectivity 6116202-1 is RoHS Compliant. Both alternatives satisfy regulatory requirements for restricted substance elimination.
