Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449539 is determined by strict alignment of the following critical parameters:

• Electrical Compatibility: Current rating (8A minimum), voltage rating (320V IEC minimum), and wire gauge support (14-30 AWG)
• Mechanical Compatibility: 3-position configuration, 0.150" (3.81mm) pitch, 90° wire entry orientation, and free-hanging in-line mounting
• Termination Interface: Screw-based termination mechanism
• Material & Safety: Polyamide housing with UL94 V-0 flammability rating
• Contact Configuration: Female socket design

The substitute part Phoenix Contact 1827130 meets all critical parameters while offering an active product status and enhanced wire gauge support (0.14-1.5mm²).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827130 is a direct functional substitute for the obsolete 5449539. Both parts maintain identical electrical ratings (8A/320V IEC, 8A/300V UL), mechanical configuration (3-position, 3.81mm pitch, 90° entry), and safety certifications (UL94 V-0).

The 1827130 offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Enhanced wire gauge support (0.14-1.5mm²) provides broader application flexibility
• Rising cage clamp termination mechanism represents current Phoenix Contact design standards
• ROHS3 compliance exceeds baseline RoHS requirements
• REACH unaffected status confirms regulatory alignment

Selection of the 1827130 is appropriate for new designs, system upgrades, and replacement applications where the 5449539 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 1827130 directly replace the 5449539 in existing installations?

A: Yes. Both parts share identical electrical ratings (8A/320V IEC), mechanical dimensions (3-position, 3.81mm pitch, 90° wire entry), and termination torque specifications (0.22-0.25 Nm). The 1827130 uses a rising cage clamp termination mechanism, which is mechanically compatible with standard screw-based connection practices.

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

A: Both termination methods use M2 screws with identical torque specifications. Rising cage clamp termination provides an enhanced mechanical interface that improves wire retention and contact reliability. This represents an engineering improvement over basic screw termination.

Q: Are there wire gauge compatibility considerations?

A: The 1827130 supports a slightly broader wire gauge range (0.14-1.5mm²) compared to the 5449539 (0.2-1.5mm²). This expanded range does not affect compatibility with applications designed for the original part, as the 5449539 range is fully contained within the 1827130 specification.

Q: What packaging differences exist between these parts?

A: The 5449539 was supplied in standard packaging, while the 1827130 is available in bulk packaging. This difference does not affect electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. The 5449539 is RoHS compliant, and the 1827130 meets the more stringent ROHS3 standard. Both parts are suitable for applications requiring RoHS compliance.

Q: Why is the 5449539 classified as obsolete?

A: Product obsolescence reflects Phoenix Contact's transition to current-generation designs. The 1827130 represents the active equivalent within the COMBICON MCVR series, offering improved design standards while maintaining full backward compatibility.
