Engineering Selection Recommendations

The Phoenix Contact 1792281 is the direct substitute for the obsolete 5451006. Both components share identical mechanical and electrical specifications across all critical parameters, ensuring direct compatibility in existing applications.

The 1792281 offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The component maintains full compliance with current RoHS3 regulations, compared to the legacy RoHS compliance of the 5451006. The rising cage clamp termination mechanism in the 1792281 provides an enhanced screw termination design while maintaining the same torque specification and wire gauge compatibility.

The UL current rating improvement (15A versus 12A) in the 1792281 provides additional operational margin without affecting IEC ratings or mechanical form factor. Both components are rated for identical voltage levels (630V IEC, 300V UL) and accommodate the same wire gauge range.

Frequently Asked Questions (FAQ)

Q: Can the 1792281 directly replace the 5451006 in existing installations?

A: Yes. Both components share identical pitch (0.200"/5.08mm), position count (6), mounting type (free-hanging in-line), wire entry angle (90°), wire gauge compatibility (12-30 AWG), screw size (M3), and torque specifications (0.5-0.6 Nm). Mechanical and electrical compatibility is complete.

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

A: The 1792281 uses a rising cage clamp mechanism within the screw termination design. Both maintain identical torque specifications (0.5-0.6 Nm) and wire gauge acceptance (12-30 AWG/0.2-2.5mm²). The cage clamp design represents an enhanced termination approach while preserving all electrical and mechanical parameters.

Q: Are there voltage or current rating differences between these parts?

A: IEC ratings are identical: 12A at 630V. UL ratings differ slightly: the 5451006 is rated 12A at 300V, while the 1792281 is rated 15A at 300V. Both meet or exceed the original specification requirements.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1792281 is an active product with guaranteed long-term availability. The 5451006 is obsolete and subject to discontinuation. For new designs and ongoing maintenance, the 1792281 ensures supply chain reliability and future support.

Q: Are both components RoHS compliant?

A: Yes. The 5451006 meets RoHS compliance standards. The 1792281 meets the more current ROHS3 compliance requirements, ensuring alignment with updated environmental regulations.

Q: Do these components require different installation procedures?

A: No. Both components use identical M3 screw termination with 0.5-0.6 Nm torque specification, 7mm wire strip length, and the same mounting configuration. Installation procedures are identical.
