Engineering Selection Recommendations

The Phoenix Contact 1792359 is a direct functional equivalent to the 5451077 for all standard applications. Both components share identical electrical ratings (IEC), mechanical interfaces, and material specifications. The 1792359 offers the following advantages:

Active Product Status: The 1792359 is currently in active production, ensuring long-term availability and supply chain stability.
Enhanced UL Rating: The substitute provides 15A UL current capacity compared to 12A in the original part, offering additional margin in UL-regulated applications.
Advanced Termination: Rising cage clamp technology in the 1792359 provides improved wire retention and contact reliability.
Compliance: Both RoHS and ROHS3 compliance certifications confirm environmental and regulatory alignment.

For new designs or system replacements, the 1792359 is the recommended selection. Existing installations using the 5451077 can transition to the 1792359 without modification to mating connectors or system architecture.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792359 directly replace the 5451077 in existing installations?

A: Yes. Both components feature identical 13-position, 0.200" (5.08mm) pitch configurations with matching mechanical interfaces, electrical ratings (IEC), and wire gauge compatibility. No system modifications are required.

Q: What is the difference between screw termination and screw with rising cage clamp?

A: Both termination methods use M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp in the 1792359 provides enhanced wire retention and contact pressure consistency during thermal cycling and vibration exposure.

Q: Are there packaging differences between these parts?

A: The 5451077 is supplied with standard packaging, while the 1792359 is available in bulk packaging. Both are suitable for production environments; packaging selection depends on procurement volume and logistics requirements.

Q: Does the higher UL current rating (15A vs. 12A) affect compatibility?

A: No. The 15A UL rating in the 1792359 represents increased capability and does not impact compatibility with systems designed for 12A operation. The IEC ratings remain identical at 12A for both parts.

Q: What is the significance of ROHS3 compliance on the 1792359?

A: ROHS3 compliance indicates adherence to the latest Restriction of Hazardous Substances directive, confirming the part meets current environmental standards. The 5451077 carries RoHS compliance, confirming both parts meet hazardous substance restrictions.

Q: Are the wire strip lengths identical?

A: Yes. Both the 5451077 and 1792359 require 7mm wire strip length for proper termination and contact engagement.
