Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792870 be used as a direct replacement for the 5451501?

A: Yes. Both parts share identical electrical ratings (12A IEC, 630V IEC), physical configuration (14 positions, 5.08mm pitch, 270° entry), termination interface (M3 screw, 0.5-0.6 Nm torque), and wire acceptance specifications (12-30 AWG, 0.2-2.5mm²). The 1792870 is mechanically and electrically interchangeable with the 5451501.

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

A: The 5451501 uses standard screw termination. The 1792870 uses screw termination with rising cage clamp technology, which provides enhanced wire retention and improved contact reliability. Both termination methods are compatible with the same wire gauge range and torque specifications.

Q: Does the higher UL current rating of the 1792870 affect compatibility?

A: No. The 1792870's 15A UL rating exceeds the original 12A specification, making it suitable for all applications where the 5451501 was used. The higher rating provides additional safety margin and does not introduce any compatibility issues.

Q: Are there packaging differences between these parts?

A: The 5451501 is listed with unspecified packaging, while the 1792870 is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect electrical or mechanical performance.

Q: Is the 1792870 compliant with current environmental regulations?

A: Yes. The 1792870 carries ROHS3 compliance, which supersedes the original RoHS compliance of the 5451501. This ensures compliance with current and future environmental standards.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical pitch, position count, wire entry orientation, and mounting type ensure that the 1792870 can be substituted into any application or PCB layout designed for the 5451501 without modification.
