Phoenix Contact 5451051 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5451051 is an 11-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 12A at 630V (IEC) and 12A at 300V (UL), and accommodates wire gauges from 12-30 AWG (0.2-2.5mm²). The part is currently obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new designs requiring equivalent functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5451051 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: Must be 11 positions at 0.200" (5.08mm) spacing to ensure mechanical and electrical compatibility with mating connectors
Connector Type & Orientation: Must be a plug with female sockets and 90° wire entry for identical mounting and installation
Electrical Ratings: Must meet or exceed IEC ratings of 12A at 630V; UL ratings of 12A at 300V represent the minimum acceptable threshold
Termination Method: Screw-based termination is required; variations in termination technology (such as rising cage clamp) are acceptable if electrical and mechanical parameters remain equivalent
Wire Gauge Compatibility: Must accommodate 12-30 AWG (0.2-2.5mm²) wire sizes
Material & Safety Compliance: Housing must be polyamide-based with UL94 V-0 flammability rating; RoHS compliance is required

The Phoenix Contact 1792333 qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

The Phoenix Contact 1792333 is a direct functional equivalent to the obsolete 5451051. Both components share identical mechanical and electrical specifications across all critical parameters: 11-position configuration, 5.08mm pitch, 90° wire entry, free-hanging mounting, and equivalent current/voltage ratings under IEC standards.

The 1792333 offers the following advantages for new designs and replacement applications:

Active Product Status: The 1792333 is currently in active production, ensuring long-term availability and supply chain reliability
Enhanced UL Current Rating: The substitute provides 15A at 300V (UL), exceeding the original 12A specification, offering additional design margin
Improved Termination Technology: Rising cage clamp termination provides enhanced wire retention and contact reliability compared to standard screw termination
Current Compliance Standards: ROHS3 compliance and REACH unaffected status align with current regulatory requirements

Both components maintain identical screw torque specifications (0.5-0.6 Nm), wire gauge compatibility (12-30 AWG), and UL94 V-0 flammability ratings, ensuring drop-in compatibility in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792333 directly replace the 5451051 in existing applications?

A: Yes. Both components are mechanically and electrically equivalent across all critical parameters: 11 positions, 5.08mm pitch, 90° wire entry, free-hanging mounting, and identical IEC ratings (12A at 630V). The 1792333 is a direct substitute suitable for immediate installation.

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

A: Both termination methods use M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp design in the 1792333 provides enhanced wire retention and contact pressure consistency. This represents an improvement over standard screw termination without affecting compatibility.

Q: Are there any packaging differences between these parts?

A: The 5451051 is supplied in standard packaging, while the 1792333 is supplied in bulk packaging. This difference does not affect component functionality or electrical performance.

Q: Does the higher UL current rating (15A) of the 1792333 affect compatibility?

A: No. The 1792333's 15A UL rating exceeds the original 5451051 specification of 12A, providing additional design margin. This enhancement does not compromise compatibility and is suitable for applications originally designed for the 5451051.

Q: Are both components RoHS compliant?

A: Yes. The 5451051 is RoHS compliant, and the 1792333 is ROHS3 compliant, meeting current regulatory standards. Both components are suitable for applications requiring RoHS certification.

Q: What wire gauges are supported by the 1792333?

A: The 1792333 accommodates 12-30 AWG (0.2-2.5mm²), identical to the original 5451051, ensuring compatibility with existing wiring specifications.
