Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1790784 is determined by the following critical parameters:

• Connector Type: Must be Female Coupler to maintain mechanical and electrical compatibility
• Wire Cross-Section Range: Must accommodate 6.0mm² to 16.0mm² to ensure proper conductor seating and contact pressure
• Coding/Keying: Must feature Plus coding to prevent incorrect mating with incompatible connectors
• Manufacturer: Phoenix Contact maintains design consistency and interchangeability within its product lines
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment

The substitute part identified below meets all these criteria while offering the advantage of active product status and improved availability.

Parameter Comparison
