Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5451682 is determined by the following critical parameters:

• Connector Type & Gender: Plug with female sockets (receptacle side)
• Position Count: 9 positions
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Wire Entry Angle: 270° free-hanging orientation
• Electrical Ratings: Minimum 12A IEC current, 630V IEC voltage
• Wire Gauge Compatibility: 12-30 AWG (0.2-2.5mm²)
• Termination Method: Screw-based wire connection
• Mounting Configuration: Free hanging (in-line)
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliant

The Phoenix Contact 1834974 meets all substitution criteria as an active-status alternative within the same manufacturer's product line.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1834974 is a direct functional substitute for the obsolete 5451682. Both components share identical mechanical and electrical specifications across all critical parameters: 9-position configuration, 0.200" (5.08mm) pitch, 270° wire entry, 12A IEC current rating, and 630V IEC voltage rating.

Key distinctions between the parts are:

• Product Status: The 1834974 maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Termination Enhancement: The 1834974 incorporates rising cage clamp termination technology versus standard screw termination, providing improved wire retention and reduced installation variability.
• UL Current Rating: The 1834974 supports 15A UL current versus 12A for the 5451682, offering increased capacity under UL certification.
• Compliance: Both components are RoHS compliant and carry UL94 V-0 flammability certification.

Selection of the 1834974 is supported by active product status and enhanced electrical performance within the same mechanical envelope.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1834974 directly replace the 5451682 in existing installations?

A: Yes. Both components share identical pitch (0.200"/5.08mm), position count (9), wire entry angle (270°), mounting configuration (free hanging in-line), and electrical ratings (12A IEC, 630V IEC). Mechanical compatibility is confirmed across all mating interfaces.

Q: What is the primary difference between these two parts?

A: The 1834974 uses rising cage clamp termination technology, whereas the 5451682 uses standard screw termination. The 1834974 also provides higher UL current rating (15A versus 12A). Both maintain identical IEC ratings and mechanical dimensions.

Q: Why is the 5451682 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1834974 represents the current-generation equivalent within Phoenix Contact's COMBICON MVSTBW series.

Q: Are there packaging differences between these parts?

A: The 5451682 packaging specification is not provided. The 1834974 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts support the same wire gauge range?

A: Yes. Both components accept 12-30 AWG wire (0.2-2.5mm²) and maintain identical screw torque specifications where applicable.

Q: What certifications apply to both parts?

A: Both components are RoHS compliant and carry UL94 V-0 flammability rating. Both meet IEC and UL electrical standards as specified in the parameter comparison table.
