Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS-74401-003 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Jack, 8p8c (RJ45, Ethernet)
• Physical Orientation: 90° right-angle mounting
• Electrical Interface: Solder termination, through-hole mounting
• Shielding & EMI Protection: Shielded construction with EMI finger
• Contact Properties: Phosphor bronze material with gold finish (50.0µin thickness)
• Mechanical Features: Board lock and green LED indicators
• Environmental Ratings: Operating temperature and MSL compatibility

The RJHSE-5385 from Amphenol ICC meets all these critical parameters, establishing it as a direct functional equivalent for the obsolete SS-74401-003.
