Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792032 is a direct functional equivalent to the obsolete 5450146. Both components share identical mechanical and electrical specifications across all critical parameters: 4-position configuration, 5.00mm pitch, 90° wire entry, 12A/630V IEC rating, and identical wire gauge acceptance.

The 1792032 incorporates a rising cage clamp termination mechanism in place of standard screw termination, which provides enhanced wire retention and simplified installation without compromising electrical performance or mechanical compatibility.

The 1792032 holds active product status with ROHS3 compliance certification, compared to the obsolete status of the 5450146. This ensures ongoing availability and compliance with current regulatory requirements. The UL current rating of 15A on the 1792032 exceeds the 12A requirement of the original part, providing additional design margin.

Both components are rated MSL 1 (Unlimited) and feature identical housing materials, flammability ratings, and physical dimensions, confirming direct substitution capability in existing applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1792032 directly replace 5450146 in existing installations?

A: Yes. The 1792032 meets or exceeds all electrical and mechanical specifications of the 5450146. Identical pitch spacing (5.00mm), position count (4), wire entry angle (90°), and current/voltage ratings ensure mechanical and electrical compatibility. The rising cage clamp termination is functionally equivalent to screw termination for this application class.

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

A: Both termination methods provide secure wire connection. Screw termination requires manual screw tightening to specified torque (0.5-0.6 Nm). Rising cage clamp termination uses a spring-loaded mechanism that secures the wire when inserted, eliminating manual torque adjustment while maintaining equivalent electrical contact and retention force.

Q: Are there packaging differences between these parts?

A: The 5450146 is supplied in standard packaging, while the 1792032 is supplied in bulk packaging. Both are new original stock from Phoenix Contact. Bulk packaging does not affect component performance or compatibility.

Q: Does the higher UL current rating (15A) of the 1792032 affect compatibility?

A: No. A higher current rating indicates the substitute part can safely handle equal or greater current loads. In applications requiring 12A, the 1792032 with its 15A UL rating operates within safe margins and is fully compatible.

Q: What compliance certifications apply to the 1792032?

A: The 1792032 is ROHS3 compliant and REACH unaffected. The original 5450146 is RoHS compliant. ROHS3 represents an enhanced compliance standard that includes the ROHS requirements, ensuring the substitute meets current regulatory requirements.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both components share identical insulation height (1.024" / 26.01mm), wire strip length (7mm), screw size (M3), and housing material (Polyamide/Nylon). Direct mechanical substitution is confirmed.
