Phoenix Contact 5450159 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5450159 is a 5-position terminal block plug with female sockets, 0.197" (5.00mm) pitch, and 90° wire entry. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new designs. The part features screw termination, free-hanging in-line mounting, and is rated for 12A at 630V (IEC) with UL94 V-0 flammability compliance. Due to its obsolete status, sourcing alternatives from the active product portfolio is necessary for long-term component availability and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5450159 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current and voltage ratings (IEC and UL standards)
Mechanical Compatibility: Number of positions, pitch (5.00mm), wire entry angle (90°), and mounting type (free hanging in-line)
Termination Compatibility: Screw-based termination with M3 screw size and matching torque specifications
Wire Gauge Acceptance: Support for 12-30 AWG (0.2-2.5mm²) wire range
Material and Safety Compliance: UL94 V-0 flammability rating and RoHS compliance status

The substitute part 1792045 meets all these criteria while offering active product status and enhanced UL current rating, making it a direct functional equivalent.

Engineering Selection Recommendations

The Phoenix Contact 1792045 is the direct substitute for the obsolete 5450159. Both components share identical mechanical and electrical specifications across all critical parameters: 5-position configuration, 5.00mm pitch, 90° wire entry, M3 screw termination, and equivalent current/voltage ratings under IEC standards.

The 1792045 offers the following advantages:

Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability and supply chain reliability
Enhanced UL Rating: Provides 15A UL current capacity compared to 12A in the original part, offering improved performance margin for UL-regulated applications
Advanced Termination: Rising cage clamp screw termination provides improved wire retention and contact reliability
Compliance Upgrade: ROHS3 compliance supersedes the RoHS compliance of the original part, meeting current regulatory requirements
Identical Mechanical Interface: Direct plug-and-play replacement with no modifications to mating connectors or PCB layouts required

Selection of the 1792045 is appropriate for all applications currently using the 5450159, with no functional or compatibility limitations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792045 directly replace the 5450159 in existing assemblies?

A: Yes. Both parts share identical pitch (5.00mm), position count (5), wire entry angle (90°), mounting type (free hanging in-line), and screw termination specifications (M3, 0.5-0.6 Nm). No modifications to mating connectors, PCB layouts, or wiring harnesses are required.

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

A: The 1792045 uses rising cage clamp screw termination, which provides enhanced wire retention and contact pressure compared to standard screw termination. This improves connection reliability and reduces the risk of wire displacement during thermal cycling or vibration.

Q: Are the electrical ratings equivalent between the two parts?

A: Under IEC standards, both parts are rated for 12A at 630V, providing identical electrical performance. The 1792045 offers an enhanced UL rating of 15A compared to 12A in the 5450159, making it suitable for higher-current UL-regulated applications.

Q: What is the significance of ROHS3 compliance on the 1792045?

A: ROHS3 compliance indicates adherence to the current Restriction of Hazardous Substances directive, superseding earlier RoHS standards. This ensures the part meets current environmental and regulatory requirements for electronics manufacturing and distribution.

Q: Are there packaging differences between the two parts?

A: The 5450159 is supplied in standard packaging, while the 1792045 is supplied in bulk packaging. Both formats contain the same component; packaging selection depends on order quantity and inventory management requirements.

Q: What wire gauges are supported by the 1792045?

A: The 1792045 accepts 12-30 AWG wire (0.2-2.5mm²), identical to the 5450159. Wire strip length is 7mm for both parts.
