Engineering Selection Recommendations

The Phoenix Contact 1792375 is a direct functional equivalent to the 5451093. Both components share identical mechanical interfaces, pitch spacing, wire entry orientation, and core electrical ratings under IEC standards. The 1792375 offers the following advantages:

Active Product Status: The 1792375 remains in active production, ensuring long-term availability and supply chain continuity
Enhanced UL Current Rating: Provides 15A under UL standards compared to 12A for the 5451093, offering additional capacity margin for UL-regulated applications
Advanced Termination Technology: Rising cage clamp termination provides improved wire retention and contact reliability compared to standard screw termination
Current Compliance: ROHS3 certification represents the latest regulatory compliance standard, superseding the RoHS compliance of the obsolete 5451093

For applications requiring the 5451093, the 1792375 provides equivalent electrical and mechanical performance with superior product lifecycle status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792375 directly replace the 5451093 in existing installations?

A: Yes. Both components maintain identical 15-position configuration, 0.200" (5.08mm) pitch spacing, 90° wire entry, and free-hanging in-line mounting. Electrical ratings under IEC standards are identical (12A, 630V). The connector interface is mechanically and electrically compatible.

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

A: The 5451093 uses standard screw termination where wire is secured by tightening an M3 screw. The 1792375 uses rising cage clamp termination, which combines screw-driven clamping with a cage mechanism for enhanced wire retention and reduced risk of wire displacement during operation.

Q: Does the higher UL current rating of the 1792375 (15A vs. 12A) affect compatibility?

A: No. Higher current rating indicates greater capacity, not incompatibility. The 1792375 can safely handle applications designed for the 5451093's 12A rating. The higher rating provides additional margin for UL-regulated designs.

Q: Are there packaging differences between these parts?

A: The 5451093 is supplied in standard packaging, while the 1792375 is supplied in bulk packaging. This affects order quantities and storage but does not impact electrical or mechanical performance.

Q: Why is the 5451093 classified as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1792375 represents the current-generation equivalent with improved termination technology and compliance certifications, making it the recommended choice for new designs and ongoing maintenance.
