Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1827059

The 1827059 is the direct active equivalent for the obsolete 5439439. Selection rationale:

Product Status Alignment: The 1827059 holds active product status, ensuring long-term availability and continued manufacturer support, whereas the 5439439 is obsolete.
Electrical Equivalence: Both parts maintain identical current (8A IEC/UL) and voltage (320V IEC / 300V UL) ratings, ensuring drop-in compatibility in existing circuit designs.
Mechanical Compatibility: Identical 10-position configuration, 0.150" (3.81mm) pitch, 270° wire entry, and free-hanging in-line mounting enable direct mechanical substitution without enclosure or PCB modifications.
Compliance Certification: Both parts carry UL94 V-0 flammability rating and RoHS compliance. The 1827059 additionally carries ROHS3 and REACH Unaffected certifications, reflecting current regulatory standards.
Enhanced Termination Technology: The 1827059 incorporates Rising Cage Clamp termination, providing improved wire retention and reduced installation time compared to standard screw termination.
Wire Gauge Compatibility: The 1827059 supports 0.14-1.5mm² wire gauge, providing extended lower-gauge capability compared to the 5439439 (0.2-1.5mm²), maintaining full backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1827059 directly replace the 5439439 in existing installations?

A: Yes. Both parts share identical electrical ratings (8A / 320V IEC), mechanical configuration (10-position, 3.81mm pitch, 270° entry), and housing materials (Polyamide UL94 V-0). The 1827059 is mechanically and electrically interchangeable without circuit or enclosure modifications.

Q: What is the primary difference between the 5439439 and 1827059?

A: The 5439439 is obsolete; the 1827059 is active. The 1827059 uses Rising Cage Clamp termination technology versus standard screw termination on the 5439439, offering improved wire retention and faster installation. Both maintain identical electrical and mechanical specifications.

Q: Are there packaging differences between these parts?

A: The 5439439 is listed with unspecified packaging; the 1827059 is supplied in bulk packaging. Verify packaging requirements with your procurement department for order quantities and handling specifications.

Q: Does the 1827059 support the same wire gauge range as the 5439439?

A: The 1827059 supports 0.14-1.5mm² (14-30 AWG), while the 5439439 supports 0.2-1.5mm² (14-30 AWG). The 1827059 provides extended lower-gauge capability, maintaining full compatibility with all wire sizes supported by the original part.
