Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5437981 is determined by strict alignment of the following critical parameters:

• Number of positions: 6
• Pitch spacing: 0.197" (5.00mm)
• Connector type: Plug with female sockets
• Wire entry orientation: 90°
• Mounting configuration: Free hanging (in-line)
• Termination method: Screw-based
• Current capacity: Minimum 12A (IEC rating)
• Voltage capacity: Minimum 630V (IEC rating)
• Wire gauge compatibility: 12-30 AWG (0.2-2.5mm²)
• Screw size: M3
• Housing material: Polyamide (PA), Nylon
• Flammability compliance: UL94 V-0

The substitute part Phoenix Contact 1792058 meets all critical substitution criteria. It maintains identical position count, pitch, connector type, wire entry angle, mounting style, and wire gauge range. Both parts share M3 screw termination with identical torque specifications and polyamide housing with UL94 V-0 rating.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792058 is a direct functional substitute for the obsolete 5437981. Both components share identical mechanical and electrical specifications across all critical parameters: 6-position configuration, 5.00mm pitch, 90° wire entry, free-hanging mounting, and M3 screw termination with matching torque values.

The 1792058 offers enhanced compliance status as an active product with ROHS3 certification, compared to the obsolete status of the 5437981. The substitute's rising cage clamp termination mechanism provides equivalent screw-based connection reliability while maintaining identical current and voltage ratings under IEC standards.

The UL current rating for the 1792058 (15A) exceeds the original part specification (12A), providing additional margin within the same voltage class (300V). Wire gauge acceptance remains identical at 12-30 AWG (0.2-2.5mm²), ensuring compatibility with existing wiring harnesses and installation practices.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792058 directly replace the 5437981 in existing assemblies?

A: Yes. Both parts maintain identical pitch (5.00mm), position count (6), wire entry angle (90°), mounting configuration (free-hanging in-line), and screw termination specifications (M3, 0.5-0.6 Nm). Mechanical and electrical compatibility is confirmed across all critical parameters.

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

A: Both termination methods use M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp mechanism in the 1792058 provides an alternative wire retention design while maintaining equivalent electrical connection performance and current-carrying capacity.

Q: Are there packaging differences between these parts?

A: The 5437981 is supplied in standard packaging, while the 1792058 is available in bulk packaging. This distinction affects procurement and inventory management but does not impact functional or electrical characteristics.

Q: Does the higher UL current rating of the 1792058 (15A vs. 12A) affect compatibility?

A: No. The higher UL rating indicates the substitute part exceeds the original specification, providing additional safety margin. Both parts meet or exceed the 12A IEC current requirement. Selection should be based on system requirements, not the substitute's higher rating.

Q: What compliance certifications apply to the substitute part?

A: The 1792058 carries ROHS3 compliance and REACH unaffected status, compared to the original part's RoHS compliance. Both parts maintain UL94 V-0 flammability rating and are suitable for applications requiring these certifications.

Q: Is the wire gauge range identical between both parts?

A: Yes. Both the 5437981 and 1792058 accept wire gauges of 12-30 AWG (0.2-2.5mm²), ensuring compatibility with existing wiring specifications and installation procedures.
