Engineering Selection Recommendations

The Phoenix Contact 1792757 is a direct functional equivalent to the 5451381 across all critical electrical and mechanical parameters. Both components share identical pitch, connector configuration, wire gauge support, and screw termination specifications.

The 1792757 offers the following advantages:

Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability and supply chain reliability
Enhanced Compliance: ROHS3 certification provides updated regulatory alignment compared to the RoHS Compliant status of the 5451381
Improved Termination: Rising cage clamp technology in the 1792757 provides enhanced wire retention and connection reliability
Higher UL Current Rating: 15A UL rating versus 12A in the 5451381, providing additional margin for UL-regulated applications
Retention Latches: Non-wire side retention latches improve mechanical stability during mating and unmating cycles

For applications currently using the obsolete 5451381, direct substitution with the 1792757 is supported without circuit redesign or connector interface modifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792757 directly replace the 5451381 in existing installations?

A: Yes. Both components maintain identical pitch (0.200"/5.08mm), connector type (2-position plug with female sockets), wire gauge compatibility (12-30 AWG), and screw termination specifications (M3, 0.5-0.6 Nm). Physical and electrical interfaces are fully compatible.

Q: What is the significance of the rising cage clamp termination in the 1792757?

A: The rising cage clamp termination in the 1792757 provides mechanical wire retention during insertion and removal cycles. This feature enhances connection reliability compared to standard screw termination, reducing the risk of accidental wire displacement.

Q: Are there packaging differences between these components?

A: The 5451381 is supplied in standard packaging, while the 1792757 is available in bulk packaging. Both are suitable for production environments; packaging selection depends on order quantity and inventory management requirements.

Q: Does the higher UL current rating of the 1792757 (15A vs. 12A) affect circuit design?

A: No. The higher UL rating of the 1792757 provides additional safety margin and does not require circuit modifications. Applications designed for the 5451381 operate within the 1792757's electrical specifications.

Q: Are both components RoHS compliant?

A: Yes. The 5451381 carries RoHS Compliant certification, while the 1792757 carries the updated ROHS3 Compliant certification. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the wire strip length requirement for both components?

A: Both the 5451381 and 1792757 require 7mm wire strip length for proper screw termination and electrical contact establishment.
