Engineering Selection Recommendations

The Phoenix Contact 1792867 is the direct substitute for the obsolete 5451491 based on electrical and mechanical parameter equivalence. Key selection factors:

Product Status: The 1792867 is classified as active, ensuring ongoing availability and supply chain continuity. The 5451491 is obsolete and should not be specified for new designs.

Compliance Enhancement: The 1792867 carries ROHS3 compliance status compared to the 5451491's RoHS compliance, representing alignment with current regulatory requirements. Both components maintain UL94 V-0 flammability certification.

Electrical Performance: The 1792867 provides a higher UL current rating (15A versus 12A), offering improved margin in UL-regulated applications while maintaining full compatibility with IEC-rated systems at 12A.

Termination Method: The 1792867 employs a rising cage clamp screw termination with retention latches on the non-wire side, providing enhanced mechanical security compared to the standard screw termination of the 5451491. This feature does not affect electrical compatibility or pin configuration.

Mechanical Compatibility: All critical mechanical parameters—pitch, wire entry angle, mounting type, screw size, and torque specification—are identical, ensuring direct physical and functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792867 directly replace the 5451491 in existing installations?

A: Yes. The 1792867 is mechanically and electrically equivalent across all critical parameters: 13 positions, 0.200" (5.08mm) pitch, 270° wire entry, M3 screw termination, and identical current/voltage ratings for IEC applications. Physical form factor and mounting are identical.

Q: What is the difference between the screw termination methods?

A: The 5451491 uses standard screw termination. The 1792867 uses screw termination with a rising cage clamp mechanism and includes retention latches on the non-wire side. Both methods accept 12-30 AWG wire and operate at identical torque specifications (0.5-0.6 Nm). The cage clamp design provides additional mechanical retention without affecting electrical performance.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS compliant and meet UL94 V-0 flammability requirements. The 1792867 carries ROHS3 certification, representing current regulatory alignment. Both are suitable for applications requiring RoHS compliance.

Q: Does the higher UL current rating of the 1792867 (15A vs. 12A) affect compatibility?

A: No. The higher UL rating of the 1792867 provides additional safety margin in UL-regulated applications. For IEC-rated systems, both components are rated at 12A. The substitute can be used in any application designed for the 5451491 without derating.

Q: What is the wire gauge compatibility?

A: Both components accept 12-30 AWG wire (0.2-2.5mm²) with identical 7mm wire strip length. No wire gauge adjustment is required when substituting.

Q: Is the 1792867 available in the same packaging as the 5451491?

A: The 1792867 is supplied in bulk packaging, whereas the 5451491 packaging specification is not provided. Verify packaging requirements with your procurement process, as this does not affect functional compatibility.

Q: Why should I transition from the 5451491 to the 1792867?

A: The 5451491 is obsolete. The 1792867 is an active product with guaranteed supply chain availability. For new designs and ongoing system maintenance, the 1792867 is the specified equivalent that maintains full functional compatibility while ensuring long-term component availability.
