Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792799 be used as a direct replacement for the 5451420 in existing assemblies?

A: Yes. Both parts are 6-position, 5.08mm pitch terminal block plugs with identical mechanical mounting, wire gauge compatibility, and IEC electrical ratings. The 1792799 maintains full form, fit, and function compatibility.

Q: What is the difference in termination between these two parts?

A: The 5451420 uses standard screw termination, while the 1792799 employs screw-based rising cage clamp termination. This enhancement improves wire retention and connection security without affecting compatibility or installation procedures.

Q: Are there any voltage or current limitations when substituting the 1792799 for the 5451420?

A: No. Both parts meet or exceed the same IEC electrical specifications (12A, 630V). The 1792799 provides additional margin with a 15A UL rating compared to the 5451420's 12A UL rating, making it suitable for all applications within the original part's electrical envelope.

Q: Does the 1792799 support the same wire gauge range as the 5451420?

A: Yes. Both parts accept 12-30 AWG (0.2-2.5mm²) wire gauges with identical 7mm wire strip length and M3 screw torque specifications (0.5-0.6 Nm).

Q: What is the significance of the product status difference?

A: The 5451420 is obsolete, meaning it is no longer manufactured and inventory is limited. The 1792799 is active production, ensuring reliable availability for new designs and ongoing system support.

Q: Are both parts RoHS compliant?

A: Yes. The 5451420 is RoHS Compliant, and the 1792799 is ROHS3 Compliant, meeting current and future regulatory requirements for hazardous substance restrictions.
