Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1792294

The 1792294 is the direct functional equivalent for the obsolete 5451019. Both components share identical electrical ratings (12A IEC, 630V IEC), mechanical configuration (7-position, 5.08mm pitch, 90° entry), and wire acceptance parameters (12–30 AWG, 0.2–2.5 mm²).

Key advantages of the 1792294:

Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability and supply chain stability
Enhanced Compliance: ROHS3 Compliant certification (versus RoHS Compliant on the 5451019) and REACH Unaffected designation provide regulatory alignment for current and future market requirements
Improved Termination: Rising cage clamp screw termination offers enhanced wire retention and reduced installation variability compared to standard screw termination
Higher UL Current Rating: 15A (UL) versus 12A (UL) on the main part provides additional margin for UL-regulated applications

The 1792294 maintains full mechanical and electrical interchangeability with the 5451019 across all critical parameters. No design modifications are required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1792294 directly replace the 5451019 in existing designs?

A: Yes. Both components share identical pitch (5.08mm), position count (7), wire entry angle (90°), electrical ratings (12A IEC, 630V IEC), and wire gauge acceptance (12–30 AWG, 0.2–2.5 mm²). The rising cage clamp termination on the 1792294 is mechanically compatible with standard screw termination interfaces.

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

A: Both are screw-based termination methods. Rising cage clamp termination incorporates a spring-loaded cage mechanism that automatically secures the wire during screw insertion, reducing manual adjustment and improving consistency. Standard screw termination requires manual wire positioning before tightening.

Q: Are there packaging differences between the 5451019 and 1792294?

A: The 5451019 is listed with packaging designation "-" (not specified), while the 1792294 is supplied in Bulk packaging. Both components are functionally identical; packaging differences reflect current manufacturing and distribution practices for the active product.

Q: Does the higher UL current rating (15A) on the 1792294 affect compatibility?

A: No. The 1792294's 15A UL rating is a superset of the 5451019's 12A UL rating. Applications designed for 12A operation remain fully compliant. The higher rating provides additional capacity for designs requiring UL certification at elevated current levels.

Q: Are both components RoHS compliant?

A: Yes. The 5451019 is RoHS Compliant; the 1792294 is ROHS3 Compliant. ROHS3 represents the current regulatory standard and includes the 1792294 in the active product lifecycle. Both meet RoHS requirements for restricted substance elimination.
