Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 350793-2 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute, part number 350793-3, maintains identical specifications across all critical dimensions and functional characteristics:

Substitution Criteria:

• Connector type, contact type, and gender configuration
• Number of positions and row configuration
• Mating pitch spacing (0.250" / 6.35mm)
• Mounting methodology (through-hole solder termination)
• Shrouding design (4-wall shrouded)
• Fastening mechanism (locking ramp)
• Contact material composition and finish specifications
• Insulation material and dimensional properties
• Flammability and safety certifications

The 350793-3 is functionally and mechanically interchangeable with the 350793-2, with the primary distinction being product status transition from obsolete to active manufacturing status and enhanced RoHS3 compliance certification.
