Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0442820004 is determined by strict equivalence across the following critical parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Surface Mount
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Ratings: Cat3
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Polyamide (PA), Nylon, Glass Filled
• Operating Temperature Range: -40°C ~ 70°C
• RoHS Status: ROHS3 Compliant

The substitute part 0442820001 maintains identical electrical and mechanical specifications across all critical parameters, with the primary distinction being packaging configuration and product status transition from obsolete to active.
