Phoenix Contact 1718449 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1718449 is a 9-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component features screw-rising cage clamp termination, supporting wire gauges from 8-24 AWG (0.2-10mm²) with rated current of 41A at 1 kV (IEC) or 600V (UL).

The 1718449 is classified as obsolete. Identifying suitable substitute components is necessary to maintain system compatibility and ensure continued availability for applications requiring this terminal block configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1718449 is determined by strict equivalence across the following critical parameters:

• 9-position configuration with 0.300" (7.62mm) pitch spacing
• Female socket plug type with 180° wire entry orientation
• Free-hanging in-line mounting configuration
• Screw-rising cage clamp termination method
• 41A current rating and 1 kV voltage rating (IEC standard)
• Wire gauge compatibility: 8-24 AWG (0.2-10mm²)
• M3 screw size for termination
• Polyamide (PA) nylon housing material
• COMBICON PC series designation

The Phoenix Contact 1778133 meets all substitution criteria as an active-status equivalent component within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778133 is the direct substitute for the obsolete 1718449 terminal block plug. Both components are manufactured by Phoenix Contact within the COMBICON PC series and maintain identical electrical and mechanical specifications across all critical parameters.

The 1778133 holds active product status, ensuring ongoing availability and supply chain continuity. Both components carry RoHS compliance certification and UL94 V-0 flammability rating, meeting current regulatory requirements.

Minor dimensional variations exist: the 1778133 features an insulation height of 0.776" (19.70mm) compared to the 1718449 at 0.902" (22.90mm), and torque specification ranges differ slightly (0.5-0.8 Nm versus 0.7-0.8 Nm). These variations do not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 1778133 directly replace the 1718449 in existing installations?

A: Yes. Both components share identical electrical ratings (41A at 1 kV IEC, 600V UL), wire gauge compatibility (8-24 AWG), pitch spacing (7.62mm), and termination method (screw-rising cage clamp). The 9-position female socket plug configuration and 180° wire entry orientation are identical.

Q: What is the significance of the product status difference?

A: The 1718449 is classified as obsolete, meaning Phoenix Contact no longer manufactures or supports this part number. The 1778133 maintains active status, ensuring continued manufacturing, technical support, and supply availability.

Q: Are there packaging differences between these parts?

A: The 1718449 is supplied in standard packaging, while the 1778133 is supplied in bulk packaging. This distinction affects order quantities and logistics but does not impact component functionality or electrical performance.

Q: Do the dimensional differences affect mechanical compatibility?

A: The insulation height difference (0.902" versus 0.776") and torque range variation (0.7-0.8 Nm versus 0.5-0.8 Nm) do not compromise mechanical compatibility in standard free-hanging in-line applications. Both components maintain the same M3 screw termination interface and mounting configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1718449 and 1778133 are RoHS compliant and carry UL94 V-0 flammability certification, meeting current environmental and safety standards.
