Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439109 is determined by strict alignment with the following core parameters:

• Position Count & Pitch: 15 positions at 0.200" (5.08mm) spacing (mechanical and electrical compatibility requirement)
• Connector Type: Plug with female sockets (functional requirement)
• Mounting Configuration: Free hanging in-line orientation (installation requirement)
• Wire Entry Angle: 90° (spatial and assembly requirement)
• Electrical Ratings: Minimum 12A at 630V (IEC) and 12A at 300V (UL) (performance requirement)
• Wire Gauge Compatibility: 12-30 AWG (0.2-2.5mm²) (termination requirement)
• Housing Material & Flammability: Polyamide (PA), Nylon with UL94 V-0 rating (safety requirement)

The Phoenix Contact 1792375 meets all substitution criteria and is classified as a direct equivalent for the obsolete 5439109.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792375 is the qualified substitute for the obsolete 5439109. Selection is based on the following engineering factors:

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and equivalent electrical safety certifications. The 1792375 carries ROHS3 compliance, representing current regulatory alignment compared to the legacy RoHS compliance of the 5439109.

Product Status: The 1792375 is active in production, ensuring long-term availability and supply chain continuity. The 5439109 is obsolete and subject to inventory depletion.

Electrical Performance: The 1792375 exceeds the UL current rating (15A vs. 12A), providing enhanced performance margin while maintaining full compatibility with IEC ratings (12A at 630V). This enhancement does not compromise backward compatibility.

Termination Technology: The 1792375 incorporates rising cage clamp termination with retention latches on the wire side, compared to standard screw termination on the 5439109. This represents a functional improvement in wire retention and ease of assembly.

Mechanical Compatibility: Identical pitch, position count, mounting configuration, wire entry angle, screw size, and torque specifications ensure direct mechanical interchangeability in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792375 directly replace the 5439109 in existing applications?

A: Yes. Both parts share identical mechanical and electrical core parameters: 15 positions at 0.200" (5.08mm) pitch, 90° free-hanging in-line configuration, M3 screw termination with 0.5-0.6 Nm torque, and equivalent electrical ratings for IEC applications (12A at 630V). Physical dimensions and mounting interfaces are identical.

Q: What are the differences between these two parts?

A: The primary differences are product status, termination technology, and regulatory compliance. The 1792375 is active production with rising cage clamp termination and wire-side retention latches, compared to the obsolete 5439109 with standard screw termination. The 1792375 also carries ROHS3 compliance and provides a higher UL current rating (15A vs. 12A).

Q: Are there any compatibility concerns with wire gauge or termination?

A: No. Both parts accommodate identical wire gauge ranges (12-30 AWG / 0.2-2.5mm²) and use M3 screw termination with matching torque specifications. The rising cage clamp design of the 1792375 provides enhanced wire retention without affecting compatibility.

Q: What is the packaging difference between these parts?

A: The 5439109 is supplied with unspecified packaging (legacy part), while the 1792375 is supplied in bulk packaging. This does not affect electrical or mechanical performance.

Q: Is the 1792375 suitable for both IEC and UL applications?

A: Yes. The 1792375 meets both IEC (12A at 630V) and UL (15A at 300V) electrical ratings, maintaining full compliance with both standards. The 5439109 similarly supports both rating systems.
