Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5450078 is determined by strict equivalence across the following critical parameters:

• 12-position configuration with 0.150" (3.81mm) pitch spacing
• Female socket plug type with 270° wire entry orientation
• Free-hanging in-line mounting configuration
• Minimum 8A current rating (IEC) and 320V voltage rating (IEC)
• Screw-based termination mechanism
• Wire gauge compatibility within 14-30 AWG range
• Polyamide housing with UL94 V-0 flammability rating
• Tin contact mating finish

The Phoenix Contact 1828595 meets all substitution criteria. This part maintains identical electrical ratings, mechanical configuration, and material specifications while offering enhanced termination technology (rising cage clamp) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1828595 is the qualified substitute for the obsolete 5450078. Both parts maintain identical electrical performance (8A/320V IEC ratings) and mechanical compatibility (12-position, 3.81mm pitch, 270° free-hanging configuration). The 1828595 offers the advantage of active product status, ensuring continued availability and supply chain reliability.

Compliance certifications are equivalent: both parts carry UL94 V-0 flammability ratings and meet RoHS requirements (5450078: RoHS Compliant; 1828595: ROHS3 Compliant). The 1828595 includes REACH unaffected status, providing additional regulatory documentation.

The termination mechanism differs (rising cage clamp versus standard screw), but both employ M2 screw-based connection with equivalent electrical performance. Wire gauge compatibility is maintained across both parts for the standard 14-30 AWG range.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1828595 directly replace the 5450078 in existing installations?

A: Yes. Both parts share identical electrical ratings (8A/320V IEC), mechanical configuration (12-position, 3.81mm pitch, 270° orientation), and housing specifications (polyamide, UL94 V-0). Physical dimensions and mating interfaces are equivalent.

Q: What is the difference between the screw termination styles?

A: The 5450078 uses standard screw termination, while the 1828595 employs rising cage clamp technology. Both achieve equivalent electrical connection and current capacity. The rising cage clamp design in the 1828595 provides enhanced wire retention characteristics.

Q: Are there packaging differences between these parts?

A: The 5450078 is listed with unspecified packaging, while the 1828595 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Q: Does the wire gauge range difference affect compatibility?

A: The 1828595 supports a slightly extended lower range (0.14mm² versus 0.2mm²). Both parts accommodate the standard 14-30 AWG range. The 1828595 provides additional flexibility for smaller gauge applications.

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

A: The 5450078 is obsolete, indicating discontinued manufacturing and limited future availability. The 1828595 is active, ensuring ongoing supply, technical support, and compliance with current regulatory standards.
