Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 5451255 is based on strict electrical and mechanical compatibility criteria. The substitute part must maintain identical specifications across the following critical parameters:

• 8-position configuration with 0.200" (5.08mm) pitch spacing
• Female socket plug type with 90° wire entry orientation
• Free-hanging in-line mounting configuration
• Minimum current rating of 12A (IEC) and voltage rating of 630V (IEC)
• Wire gauge acceptance range of 12-30 AWG (0.2-2.5mm²)
• Screw-based termination method
• Polyamide housing with UL94 V-0 flammability rating
• M3 screw size with 0.5-0.6 Nm torque specification

The Phoenix Contact 1835151 meets all these criteria, providing direct functional equivalence while offering enhanced specifications in certain areas.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1835151 is the direct equivalent for the obsolete 5451255. Both components share identical electrical ratings (12A at 630V IEC), mechanical configuration (8-position, 0.200" pitch, 90° free-hanging), and housing specifications (Polyamide UL94 V-0). The 1835151 is currently in active production status, ensuring long-term availability and supply chain continuity.

The 1835151 incorporates a rising cage clamp termination mechanism compared to the standard screw termination of the 5451255, providing enhanced wire retention characteristics while maintaining the same M3 screw torque specification (0.5-0.6 Nm). The substitute part exceeds the original specification in UL current rating (15A versus 12A), offering improved performance margin for UL-compliant applications.

Both parts maintain identical RoHS compliance status and wire gauge acceptance (12-30 AWG / 0.2-2.5mm²), ensuring seamless integration into existing designs. The 1835151's ROHS3 certification and active product status make it the recommended selection for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1835151 directly replace the 5451255 in existing installations?

A: Yes. Both components share identical electrical ratings (12A at 630V IEC), mechanical pitch (0.200" / 5.08mm), position count (8), wire entry angle (90°), and mounting configuration (free-hanging in-line). The housing material, flammability rating, and wire gauge acceptance are identical.

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

A: The 5451255 uses standard screw termination. The 1835151 uses screw-based rising cage clamp termination, which provides enhanced wire retention and strain relief. Both maintain the same M3 screw size and 0.5-0.6 Nm torque specification.

Q: Are there any compliance differences between these parts?

A: The 5451255 is RoHS Compliant. The 1835151 is ROHS3 Compliant, representing a more current regulatory standard. Both maintain UL94 V-0 flammability ratings and identical IEC electrical specifications.

Q: Does the 1835151 support the same wire gauge range?

A: Yes. Both components accept wire gauges from 12-30 AWG (0.2-2.5mm²) with identical 7mm wire strip length requirements.

Q: What is the current availability status of these parts?

A: The 5451255 is obsolete. The 1835151 is in active production with current inventory availability, ensuring reliable supply for ongoing applications and new designs.
