Phoenix Contact 1718407 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1718407 is a 5-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 1718407 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1718407 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (41A IEC), voltage rating (1 kV IEC), and wire gauge compatibility (8-24 AWG / 0.2-10mm²)
• Mechanical Interface: 5-position configuration, 0.300" (7.62mm) pitch, 180° plug wire entry, and free-hanging in-line mounting
• Termination Method: Screw-rising cage clamp connection
• Material & Safety: Polyamide housing, UL94 V-0 flammability rating, and M3 screw specification
• Regulatory Compliance: RoHS compliance status

The substitute part 1778094 maintains equivalence across all critical electrical and mechanical parameters, with documented differences noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778094 is a direct functional equivalent to the obsolete 1718407 for applications requiring a 5-position, 7.62mm pitch terminal block plug with screw-rising cage clamp termination.

Substitution Basis:

The 1778094 maintains full electrical equivalence (41A at 1 kV IEC / 600V UL) and mechanical compatibility across all critical interface parameters. Both components share identical wire gauge ratings (8-24 AWG), housing material (Polyamide/Nylon), flammability certification (UL94 V-0), and regulatory compliance (RoHS).

Documented Differences:

• Product Status: The 1778094 is active production, ensuring long-term availability compared to the obsolete 1718407
• Torque Range: The 1778094 specifies 0.5-0.8 Nm versus 0.7-0.8 Nm for the 1718407, providing a wider lower tolerance margin
• Insulation Height: The 1778094 measures 0.776" (19.70mm) versus 0.902" (22.90mm) for the 1718407, a 0.126" (2.20mm) reduction
• Features: The 1718407 includes "Retention Latches (Non-Wire Side)" while the 1778094 specifies "Latch Lock" only
• RoHS Certification: The 1778094 carries ROHS3 compliance versus RoHS Compliant for the 1718407
• REACH Status: The 1778094 is documented as REACH Unaffected

For applications where the reduced insulation height or feature differences present constraints, the 1778094 remains electrically and mechanically suitable for direct substitution in standard 7.62mm pitch terminal block configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1778094 directly replace the 1718407 in existing designs?

A: Yes. Both components share identical electrical ratings (41A at 1 kV IEC), mechanical pitch (7.62mm), wire gauge compatibility (8-24 AWG), and termination method (screw-rising cage clamp). The primary design consideration is the 0.126" (2.20mm) reduction in insulation height on the 1778094. Verify that your PCB or mounting structure accommodates this dimensional difference.

Q: What is the significance of the torque range difference?

A: The 1778094 specifies a torque range of 0.5-0.8 Nm compared to 0.7-0.8 Nm for the 1718407. This represents a wider lower tolerance on the 1778094. Both ranges are within acceptable limits for M3 screw connections in terminal block applications. Use the appropriate torque specification for each part during assembly.

Q: Are there packaging differences between these parts?

A: Yes. The 1718407 is listed with packaging designation "-" (not specified), while the 1778094 is supplied in Bulk packaging. Confirm bulk packaging specifications with your supplier if specific packaging requirements exist for your procurement process.

Q: Does the feature difference (Retention Latches vs. Latch Lock) affect substitution?

A: Both components include latch mechanisms for secure mating. The 1718407 specifies "Latch Lock, Retention Latches (Non-Wire Side)" while the 1778094 specifies "Latch Lock." Both provide mechanical retention. Verify your application does not require the specific non-wire side retention feature documented for the 1718407.

Q: What is the inventory status for each part?

A: The 1718407 (obsolete) has 776 pcs in stock. The 1778094 (active) has 1076 pcs in stock. For new designs or long-term production, the 1778094 is recommended due to active product status and higher available inventory.

Q: Are both parts RoHS compliant?

A: Yes. The 1718407 is RoHS Compliant. The 1778094 is ROHS3 Compliant, representing a more current certification standard. Both meet RoHS requirements. The 1778094 additionally carries REACH Unaffected status.
