Phoenix Contact 5439015 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439015 is a 6-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 12A at 630V (IEC) and 12A at 300V (UL), and accommodates wire gauges from 12-30 AWG (0.2-2.5mm²). The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439015 is determined by strict alignment with the following critical parameters:

6-position configuration with 0.200" (5.08mm) pitch spacing
Female socket plug type with 90° wire entry orientation
Free-hanging in-line mounting configuration
Screw-based termination mechanism
Wire gauge compatibility: 12-30 AWG (0.2-2.5mm²)
Electrical ratings: minimum 12A at 630V (IEC) and 12A at 300V (UL)
M3 screw size with 0.5-0.6 Nm torque specification
Polyamide housing with UL94 V-0 flammability rating

The substitute part Phoenix Contact 1792281 meets all these criteria while offering enhanced features including rising cage clamp termination and retention latches on the wire side, with improved UL current rating (15A vs. 12A).

Engineering Selection Recommendations

The Phoenix Contact 1792281 is the direct substitute for the obsolete 5439015. Both components share identical mechanical and electrical specifications across all critical parameters: 6-position configuration, 0.200" pitch, 90° wire entry, free-hanging mounting, and wire gauge compatibility.

The 1792281 offers operational advantages while maintaining full compatibility: active product status ensures ongoing availability, ROHS3 compliance exceeds the RoHS compliance of the original part, and the rising cage clamp termination with retention latches provides enhanced wire retention compared to standard screw termination. The UL current rating improvement from 12A to 15A provides additional margin for applications operating near rated capacity.

Both components carry identical IEC ratings (12A at 630V), M3 screw specifications with 0.5-0.6 Nm torque, and UL94 V-0 flammability certification. The 1792281 is available in active inventory (824 pcs) and represents the current production equivalent for this terminal block configuration.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792281 directly replace the 5439015 in existing installations?

A: Yes. Both components share identical mechanical dimensions, pitch spacing (0.200"), wire gauge compatibility (12-30 AWG), and electrical ratings (12A at 630V IEC). The 1792281 features rising cage clamp termination instead of standard screw termination, which provides enhanced wire retention without affecting mechanical or electrical compatibility.

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

A: Both termination methods use M3 screws with identical torque specifications (0.5-0.6 Nm). Rising cage clamp termination incorporates a mechanical cage that rises as the screw tightens, providing positive wire retention and reducing the risk of wire displacement. Standard screw termination relies on direct screw pressure alone.

Q: Are the electrical ratings identical between these two parts?

A: IEC ratings are identical: 12A at 630V. UL ratings differ slightly: the 5439015 is rated 12A at 300V, while the 1792281 is rated 15A at 300V. Both exceed the minimum requirements for standard applications.

Q: What is the significance of the product status difference?

A: The 5439015 is obsolete, meaning Phoenix Contact no longer manufactures or supports this part. The 1792281 is active, ensuring continued availability, technical support, and compliance with current regulatory standards (ROHS3 vs. RoHS).

Q: Are there any packaging differences between these parts?

A: The 5439015 packaging is listed as unspecified, while the 1792281 is supplied in bulk packaging. Both are suitable for component-level integration into terminal block assemblies.

Q: Do both parts meet the same flammability and compliance standards?

A: Yes. Both components carry UL94 V-0 flammability certification, MSL 1 (Unlimited) moisture sensitivity rating, and ECCN EAR99 classification. The 1792281 additionally carries REACH Unaffected status and ROHS3 compliance, exceeding the regulatory requirements of the original part.
