Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439581 is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 6 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Electrical Ratings: The substitute must support minimum current and voltage ratings equal to or exceeding the original part's specifications. The 5439581 operates at 12A (IEC) and 630V (IEC); substitute parts must meet or exceed these values.

Wire Gauge Compatibility: The substitute must accept 12-30 AWG wire gauges (0.2-2.5mm²) to maintain compatibility with existing wiring harnesses.

Mounting and Orientation: The substitute must feature 270° free-hanging in-line mounting with female socket configuration to ensure direct mechanical replacement.

Termination Method: Screw-based termination is required for compatibility with existing installation procedures and tooling.

Compliance and Material Standards: RoHS compliance and UL94 V-0 flammability rating must be maintained.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1937758 is a direct functional substitute for the obsolete 5439581 terminal block plug. Both parts share identical mechanical interfaces, position counts, pitch specifications, and wire gauge compatibility.

The 1937758 is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain RoHS compliance and UL94 V-0 flammability ratings, meeting regulatory requirements for industrial applications.

The 1937758 features an enhanced screw-clamping yoke termination mechanism compared to the standard screw termination of the 5439581, providing improved wire retention and contact reliability. This represents a technical advancement rather than a limitation.

For IEC voltage applications, the 5439581 is rated at 630V while the 1937758 is rated at 320V. In applications where the full 630V IEC rating is required, the 1937758 may not be suitable. For UL-compliant applications, the 1937758 exceeds the original specification with 15A current capacity versus the 5439581's 12A rating.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1937758 directly replace the 5439581 in existing installations?

A: Yes, for applications operating within the 1937758's electrical ratings. Both parts feature identical 6-position, 5.00mm pitch configurations with 270° free-hanging mounting. Mechanical compatibility is assured. Verify that your application's voltage and current requirements fall within the 1937758's specifications (320V IEC, 15A UL, 300V UL).

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

A: The 5439581 uses standard screw termination, while the 1937758 incorporates a screw-clamping yoke with tension sleeve mechanism. This enhancement improves wire retention and contact pressure consistency. Both methods are screw-based and compatible with standard installation procedures.

Q: Why is the 5439581 listed as obsolete?

A: The 5439581 has been discontinued by Phoenix Contact. The 1937758 represents the current production equivalent, offering improved termination technology and active supply chain support.

Q: Are there any packaging differences between these parts?

A: The 5439581 packaging specification is not provided. The 1937758 is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: What wire gauges are compatible with both parts?

A: Both the 5439581 and 1937758 accept 12-30 AWG wire gauges, equivalent to 0.2-2.5mm² cross-sectional area. Wire strip length for both is 7mm.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5439581 and 1937758 are RoHS compliant and carry UL94 V-0 flammability ratings, meeting regulatory requirements for industrial and commercial applications.
