Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5449678 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (320V IEC / 300V UL), and wire gauge range (14-30 AWG / 0.2-1.5mm²)
• Mechanical Compatibility: 2-position configuration, 0.150" (3.81mm) pitch, 90° plug wire entry, free-hanging in-line mounting
• Termination Interface: Screw-based termination (including rising cage clamp variants)
• Material & Safety: Polyamide housing, UL94 V-0 flammability rating, tin contact mating finish
• Connector Type: Female socket plug configuration with mating flange

The substitute part Phoenix Contact 1828346 meets all critical substitution criteria while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1828346 is the direct active equivalent for the obsolete 5449678. Both components share identical electrical ratings (8A / 320V IEC), mechanical configuration (2-position, 3.81mm pitch, 90° entry), and safety certifications (UL94 V-0).

The 1828346 offers enhanced compliance status with ROHS3 certification and REACH unaffected designation, compared to the base RoHS compliance of the 5449678. The termination mechanism upgrade to rising cage clamp technology in the 1828346 provides improved contact reliability while maintaining M2 screw compatibility.

Wire gauge compatibility is fully maintained, with the 1828346 supporting the full 14-30 AWG range of the original part, with extended lower-gauge support (0.14mm² minimum versus 0.2mm² minimum).

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1828346 directly replace 5449678 in existing applications?

A: Yes. Both parts share identical electrical ratings (8A / 320V IEC), mechanical pitch (3.81mm), connector orientation (90° free-hanging), and housing material (polyamide UL94 V-0). The M2 screw termination interface is compatible between both parts.

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

A: The 5449678 uses standard screw termination, while the 1828346 uses screw-based rising cage clamp termination. Both employ M2 screws and are mechanically compatible with the same mating connectors.

Q: Are there packaging differences between these parts?

A: The 5449678 is listed with unspecified packaging, while the 1828346 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the 1828346 support the same wire gauge range?

A: The 1828346 supports 14-30 AWG (0.14-1.5mm²), which encompasses the full 14-30 AWG range (0.2-1.5mm²) of the 5449678, with extended support for smaller gauge wires.

Q: What compliance advantages does the 1828346 offer?

A: The 1828346 carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment compared to the base RoHS compliance of the 5449678. Both maintain EAR99 export classification and identical HTSUS coding.

Q: Is the 1828346 currently available?

A: Yes. The 1828346 is classified as active product status with 1476 pieces in stock, compared to the obsolete 5449678 with 689 pieces remaining inventory.
