Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1778146 qualifies as a direct substitute for the 1718452 based on the following critical parameters:

• Identical number of positions (10)
• Identical pitch specification (0.300" / 7.62mm)
• Identical connector type (Plug, Female Sockets)
• Identical mounting configuration (Free Hanging In-Line)
• Identical termination method (Screw - Rising Cage Clamp)
• Identical electrical ratings (41A IEC, 1 kV IEC, 41A UL, 600V UL)
• Identical wire gauge compatibility (8-24 AWG / 0.2-10mm²)
• Identical housing material (Polyamide/Nylon)
• Identical flammability rating (UL94 V-0)
• Identical RoHS compliance status

The 1778146 is an active product, whereas the 1718452 is obsolete, making it the recommended replacement for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778146 is the direct equivalent for the obsolete 1718452. Both components meet identical electrical specifications, mechanical configurations, and compliance requirements. The 1778146 maintains active product status with Phoenix Contact, ensuring ongoing availability and supply chain reliability. For applications currently using the 1718452, direct substitution with the 1778146 is supported without design modification. The transition from obsolete to active status does not introduce compatibility concerns, as all functional and electrical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 1778146 be used as a direct replacement for the 1718452 in existing assemblies?

A: Yes. Both components share identical electrical ratings (41A IEC, 1 kV IEC), mechanical configuration (10 positions, 0.300" pitch), termination method (screw-rising cage clamp), and wire gauge compatibility (8-24 AWG). No design changes are required.

Q: What is the primary difference between these two parts?

A: The 1718452 is classified as obsolete, while the 1778146 is an active product. The 1778146 also features a reduced torque specification range (0.5-0.8 Nm versus 0.7-0.8 Nm) and a lower insulation height (0.776" versus 0.902"). These differences do not affect functional compatibility in standard applications.

Q: Are there packaging differences between the 1718452 and 1778146?

A: The 1718452 is supplied with unspecified packaging, while the 1778146 is supplied in bulk packaging. Both are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Which part should be specified for new designs?

A: The Phoenix Contact 1778146 should be specified for all new designs and procurement activities. As an active product, it ensures supply chain continuity and manufacturer support.
