Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1835009 is a direct substitute for the obsolete 5451718. Both components share identical mechanical and electrical specifications across all critical parameters: 12-position configuration, 5.08mm pitch, 270° wire entry, and equivalent current/voltage ratings under IEC standards.

The 1835009 offers enhanced compliance status (ROHS3 vs. RoHS Compliant) and active product availability, making it the appropriate selection for new designs and obsolescence mitigation. The substitute's rising cage clamp termination mechanism and higher UL current rating (15A vs. 12A) provide additional operational margin without compromising compatibility.

Both components maintain identical insulation height, housing material, and flammability rating, ensuring mechanical fit and safety performance equivalence in existing mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1835009 directly replace the 5451718 in existing installations?

A: Yes. Both components share identical pitch (5.08mm), position count (12), wire entry angle (270°), mounting type (free-hanging in-line), and wire gauge range (12-30 AWG / 0.2-2.5mm²). Mechanical and electrical compatibility is confirmed across all critical parameters.

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

A: The 5451718 uses standard screw termination, while the 1835009 employs screw-based rising cage clamp termination. Both are screw-actuated connection methods compatible with the same wire gauge range and mounting configuration.

Q: Does the higher UL current rating of the 1835009 (15A vs. 12A) affect compatibility?

A: No. The substitute's higher UL rating (15A) provides additional capacity without reducing compatibility. The IEC current rating remains equivalent at 12A for both parts. System design should reference the applicable standard (IEC or UL) for the installation.

Q: Are there packaging differences between these parts?

A: The 5451718 is listed with unspecified packaging, while the 1835009 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Q: What compliance certifications apply to the 1835009?

A: The 1835009 carries ROHS3 compliance and REACH unaffected status, representing current regulatory alignment. Both components maintain UL94 V-0 flammability rating and are suitable for industrial control applications.
