Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451048 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical pitch (0.200"/5.08mm), position count (10), and connector type (plug with female sockets)
• Mechanical Compatibility: Matching mounting configuration (free hanging in-line), wire entry angle (90°), and housing material (polyamide/nylon)
• Electrical Ratings: Equivalent or superior current and voltage ratings across both IEC and UL standards
• Wire Accommodation: Identical wire gauge range (12-30 AWG / 0.2-2.5mm²)
• Termination Method: Screw-based termination with compatible torque specifications

The substitute part Phoenix Contact 1792320 meets all these criteria while offering enhanced product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792320 is a direct functional substitute for the 5451048. Both components share identical mechanical and electrical specifications across all critical parameters, including pitch, position count, wire entry angle, current/voltage ratings (IEC), wire gauge accommodation, and termination torque.

The 1792320 offers the following advantages:

• Active Product Status: The 1792320 is currently in active production, ensuring long-term availability and supply chain stability compared to the obsolete 5451048.
• Enhanced Compliance: The 1792320 carries ROHS3 Compliant and REACH Unaffected certifications, providing superior regulatory alignment for modern applications.
• Improved UL Rating: The 1792320 supports 15A at 300V (UL), compared to 12A for the 5451048, offering additional current capacity within the same voltage envelope.
• Advanced Termination: The rising cage clamp termination in the 1792320 provides enhanced wire retention and connection reliability compared to standard screw termination.

Both components maintain identical mechanical form factors, allowing direct replacement in existing designs without modification to mounting or interconnect infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792320 directly replace the 5451048 in existing applications?

A: Yes. Both components are mechanically and electrically equivalent across all critical parameters: 10-position configuration, 0.200" (5.08mm) pitch, 90° free-hanging in-line mounting, identical wire gauge accommodation (12-30 AWG), and matching screw termination torque specifications (0.5-0.6 Nm). The 1792320 is a direct functional substitute.

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

A: The 5451048 uses standard screw termination, while the 1792320 employs screw termination with a rising cage clamp mechanism. Both maintain identical torque specifications (0.5-0.6 Nm) and wire gauge compatibility. The rising cage clamp in the 1792320 provides enhanced wire retention during connection.

Q: Are there any electrical rating differences between these components?

A: Both parts are rated identically for IEC standards (12A at 630V). Under UL standards, the 1792320 provides a higher current rating of 15A compared to the 5451048's 12A, while maintaining the same 300V voltage rating. Both support the same wire gauge range (12-30 AWG / 0.2-2.5mm²).

Q: Why should I choose the 1792320 over the 5451048?

A: The 5451048 is classified as obsolete, making the 1792320 the appropriate choice for new designs and ongoing maintenance. The 1792320 is in active production, carries current compliance certifications (ROHS3, REACH Unaffected), and offers superior UL current ratings and advanced termination technology.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical mechanical specifications: 0.200" (5.08mm) pitch, 1.024" (26.01mm) insulation height, M3 screw size, and 7mm wire strip length. They are mechanically interchangeable without modification to mounting infrastructure.

Q: What is the packaging difference between these parts?

A: The 5451048 is supplied with unspecified packaging, while the 1792320 is supplied in bulk packaging. This does not affect functional compatibility or electrical performance.
