Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1834916 is the qualified substitute for the obsolete 5451624. Both components maintain identical electrical performance under IEC standards (12A, 630V) and equivalent UL ratings (300V). The 1834916 provides enhanced UL current capacity (15A vs. 12A), representing a performance improvement without degradation of the original specification.

The 1834916 carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The transition from standard screw termination to rising cage clamp termination provides improved contact reliability and simplified wire insertion procedures. Both components share identical mechanical form factors, pitch spacing, and housing materials, supporting direct mechanical interchange in free-hanging in-line configurations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1834916 directly replace the 5451624 in existing installations?

A: Yes. Both components share identical pitch (5.08mm), position count (3), wire entry angle (270°), mounting type (free hanging in-line), and electrical ratings under IEC standards. The 1834916 meets or exceeds all original specifications.

Q: What is the significance of the termination style difference (Screw vs. Screw - Rising Cage Clamp)?

A: The rising cage clamp termination in the 1834916 provides an alternative wire insertion mechanism while maintaining screw-based electrical connection. Both termination methods are compatible with the specified wire gauge range (12-30 AWG / 0.2-2.5mm²).

Q: Does the higher UL current rating (15A vs. 12A) on the 1834916 affect compatibility?

A: No. The higher UL current rating represents increased capacity and does not create incompatibility. The component remains suitable for applications designed for 12A operation.

Q: Are there packaging differences between these parts?

A: The 5451624 is listed with unspecified packaging, while the 1834916 is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: What compliance advantages does the 1834916 offer?

A: The 1834916 carries ROHS3 compliance and active product status, ensuring regulatory alignment and continued manufacturer support. The 5451624, classified as obsolete, may face supply constraints and lacks current compliance documentation.
