Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1718397 is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Phoenix Contact COMBICON PC)
• Identical position count (4 positions)
• Matching pitch specification (0.300" / 7.62mm)
• Identical connector type (Plug, Female Sockets)
• Matching mounting configuration (Free Hanging In-Line)
• Equivalent termination method (Screw - Rising Cage Clamp)
• Compatible wire gauge range (8-24 AWG / 0.2-10mm²)
• Electrical ratings meeting or exceeding original specifications (41A IEC, 1 kV IEC)
• Housing material compatibility (Polyamide/Nylon)
• Flammability compliance (UL94 V-0)

The Phoenix Contact 1778081 meets all substitution criteria as an active product within the same COMBICON PC series, maintaining functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778081 is the direct active equivalent for the obsolete 1718397 model. Both components maintain identical electrical specifications, mechanical dimensions, and functional characteristics within the COMBICON PC series. The 1778081 carries active product status, ensuring ongoing availability and supply chain continuity.

Compliance considerations: The 1778081 meets ROHS3 requirements, representing current regulatory compliance standards. Both parts maintain UL94 V-0 flammability ratings and REACH unaffected status, confirming suitability for regulated applications.

Minor dimensional variation exists in insulation height (1718397: 0.902" vs. 1778081: 0.776"), which does not affect functional compatibility in standard mounting configurations. Torque specification ranges differ slightly (1718397: 0.7-0.8 Nm vs. 1778081: 0.5-0.8 Nm), with the substitute accommodating the original specification within its lower tolerance band.

Frequently Asked Questions (FAQ)
