Phoenix Contact 5451446 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5451446 is an 8-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 designs requiring equivalent functionality.

The BCVP series plug accepts 12-30 AWG wire (0.2-2.5mm²) and operates at 12A (IEC) / 12A (UL) with voltage ratings of 630V (IEC) / 300V (UL). Screw termination with M3 fasteners and UL94 V-0 flammability rating provide reliable electrical connections in industrial applications.

The substitute part Phoenix Contact 1792812 maintains all critical mechanical and electrical parameters while offering enhanced termination technology (Rising Cage Clamp) and improved current capacity under UL standards (15A vs. 12A).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1792812

The 1792812 is the direct functional equivalent for the obsolete 5451446. Both components share identical mechanical pitch, position count, wire gauge acceptance, and core electrical ratings under IEC standards. The substitute maintains full compatibility with existing connector receptacles and mounting configurations.

The 1792812 offers two advantages over the original part:

1. Active Product Status: The 1792812 is currently in active production with 1647 units in stock, ensuring long-term availability and supply chain continuity.

2. Enhanced Termination Technology: Rising Cage Clamp termination provides improved wire retention and contact reliability compared to standard screw termination, while maintaining identical M3 screw torque specifications.

3. Improved UL Current Rating: The substitute achieves 15A under UL standards versus 12A for the original part, providing additional capacity margin for applications operating at or near rated current limits.

Both components maintain UL94 V-0 flammability compliance and RoHS certification, meeting regulatory requirements for industrial terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1792812 directly replace the 5451446 in existing installations?

A: Yes. Both components feature identical 8-position, 0.200" (5.08mm) pitch spacing, 270° wire entry orientation, and free-hanging in-line mounting. The M3 screw termination torque specification (0.5-0.6 Nm) is identical. Existing connector receptacles and mounting hardware are fully compatible.

Q: What is the difference between standard screw termination and Rising Cage Clamp termination?

A: Rising Cage Clamp termination in the 1792812 provides enhanced wire retention through a spring-loaded clamping mechanism that secures the wire during insertion. Standard screw termination in the 5451446 requires manual screw tightening. Both methods achieve equivalent electrical performance and meet the same torque specifications.

Q: Are there any electrical performance differences between these parts?

A: Under IEC standards, both components are rated for 12A at 630V. The 1792812 achieves a higher UL current rating of 15A compared to 12A for the 5451446. For applications operating under IEC standards, electrical performance is equivalent. For UL-regulated applications, the 1792812 provides additional current capacity.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 5451446 is no longer manufactured by Phoenix Contact. The 1792812 is in active production with current inventory availability. For new designs or long-term system maintenance, the 1792812 is the recommended choice to ensure continued component availability and supply chain stability.

Q: Are both components RoHS compliant?

A: Yes. The 5451446 is RoHS Compliant. The 1792812 is ROHS3 Compliant, representing compliance with the current revision of the RoHS directive. Both meet regulatory requirements for hazardous substance restrictions.

Q: What wire gauges are compatible with both components?

A: Both the 5451446 and 1792812 accept wire gauges from 12-30 AWG (0.2-2.5mm²). Wire strip length for termination is 7mm for both components.
