Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451462 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (12A IEC minimum, 630V IEC minimum)
• Physical Compatibility: 10-position configuration, 0.200" (5.08mm) pitch, and 270° free-hanging in-line mounting must be identical
• Termination Compatibility: Screw-based termination style ensures mechanical and electrical interface compatibility
• Wire Gauge Acceptance: 12-30 AWG (0.2-2.5mm²) range must be maintained
• Material and Safety Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The substitute part Phoenix Contact 1792838 meets all critical substitution criteria while offering enhanced features and active product status.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1792838 is the direct functional equivalent for applications currently using 5451462. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical IEC ratings (12A, 630V) and UL voltage rating (300V). The substitute provides enhanced UL current rating (15A vs. 12A), which does not compromise backward compatibility.

Physical and Mechanical Equivalence: Identical pitch (5.08mm), position count (10), wire entry angle (270°), and mounting configuration ensure direct mechanical interchangeability without PCB or connector redesign.

Termination Compatibility: Both parts use M3 screw termination with identical torque specifications (0.5-0.6 Nm). The substitute's rising cage clamp enhancement provides improved wire retention without affecting screw-based interface compatibility.

Compliance and Longevity: The substitute carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original part's obsolete status necessitates transition to 1792838 for new designs and ongoing procurement.

Material and Safety: Identical polyamide housing and UL94 V-0 flammability rating maintain thermal and fire safety performance across both parts.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1792838 directly replace 5451462 in existing assemblies?

A: Yes. Both parts share identical electrical ratings (12A IEC, 630V IEC, 300V UL), pitch (5.08mm), position count (10), wire entry angle (270°), and screw termination specifications. Physical and electrical interchangeability is confirmed.

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

A: The 5451462 uses standard screw termination. The 1792838 uses screw termination with rising cage clamp technology, which enhances wire retention during insertion. Both maintain identical M3 screw size and torque specifications (0.5-0.6 Nm), ensuring compatibility with existing assembly procedures.

Q: Does the substitute part support the same wire gauge range?

A: Yes. Both parts accept 12-30 AWG wire (0.2-2.5mm²) with identical 7mm wire strip length, ensuring no changes to wire preparation or assembly processes.

Q: Why is the original part obsolete?

A: The 5451462 is classified as obsolete by Phoenix Contact. The 1792838 represents the active product line continuation with equivalent functionality and enhanced features, ensuring long-term availability and regulatory compliance.

Q: Are there any compliance differences between the two parts?

A: The 5451462 carries RoHS Compliant status. The 1792838 carries ROHS3 Compliant status, representing updated regulatory alignment. Both maintain UL94 V-0 flammability rating and are suitable for equivalent applications.

Q: What is the current rating difference in UL specifications?

A: The 5451462 is rated 12A (UL). The 1792838 is rated 15A (UL). This enhancement does not affect backward compatibility; applications designed for 12A operation remain fully supported.

Q: Are packaging differences relevant to substitution?

A: The 5451462 is supplied in standard packaging. The 1792838 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement volume requirements.
