Phoenix Contact 5451792 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5451792 is a 20-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 270° free-hanging in-line mounting. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 12A (IEC) / 12A (UL) and 630V (IEC) / 300V (UL), with screw termination and polyamide housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451792 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current and voltage ratings (IEC and UL standards)
• Physical Compatibility: Number of positions (20), pitch (5.08mm), and mounting type (free hanging in-line)
• Mechanical Compatibility: Wire entry angle (270°), wire gauge acceptance (12-30 AWG / 0.2-2.5mm²), and connector type (plug with female sockets)
• Material & Safety: Housing material (polyamide/nylon), flammability rating (UL94 V-0), and RoHS compliance
• Termination Method: Screw-based termination systems

The substitute part Phoenix Contact 1835083 meets all critical substitution criteria. Both parts share identical position count, pitch, wire entry orientation, mounting configuration, wire gauge range, housing material, flammability rating, and RoHS compliance status. Variations in termination mechanism (rising cage clamp vs. standard screw) and retention latch positioning do not prevent functional substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1835083 is the qualified substitute for the obsolete 5451792. Both parts maintain identical electrical performance under IEC standards (12A, 630V) and equivalent UL performance (15A vs. 12A at 300V). The 1835083 offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The substitute part incorporates rising cage clamp termination technology, which represents an enhancement over standard screw termination while maintaining full mechanical and electrical compatibility. The increased UL current rating (15A) of the 1835083 provides additional design margin in applications operating at or near the 12A IEC specification.

Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability standards, making them suitable for equivalent deployment in regulated industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1835083 directly replace 5451792 in existing installations?

A: Yes. Both parts share identical position count (20), pitch (5.08mm), wire entry angle (270°), mounting configuration (free hanging in-line), wire gauge acceptance (12-30 AWG / 0.2-2.5mm²), and electrical ratings under IEC standards. Physical and electrical compatibility is confirmed.

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

A: The 5451792 uses standard screw termination, while the 1835083 uses screw-based rising cage clamp termination. Both are screw-actuated systems; the cage clamp design provides an alternative mechanical approach to wire retention without affecting electrical performance or connector mating.

Q: Are there packaging differences between these parts?

A: The 5451792 is listed with unspecified packaging, while the 1835083 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional equivalence.

Q: Why is the UL current rating different (12A vs. 15A)?

A: The 1835083 is rated for 15A under UL standards compared to 12A for the 5451792. This difference reflects design improvements in the substitute part. Applications requiring 12A operation remain fully compliant with the 1835083 specification.

Q: Is the 1835083 suitable for new designs?

A: Yes. The 1835083 carries active product status, confirming ongoing manufacturer support and availability. It is appropriate for both replacement applications and new system designs requiring 20-position, 5.08mm pitch terminal block plugs with female sockets.

Q: Do both parts meet the same safety and compliance standards?

A: Yes. Both parts are RoHS compliant and rated UL94 V-0 for material flammability. Electrical ratings comply with both IEC and UL standards, making them suitable for equivalent deployment in regulated applications.
