Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 5449089 is determined by the following critical parameters:

• Electrical Ratings: Current (8A IEC) and voltage (320V IEC) must be maintained or exceeded
• Physical Configuration: 12 positions, 4.6mm pitch, 90° wire entry, and free-hanging mounting must remain constant
• Termination Interface: Screw-based termination ensures mechanical compatibility
• Wire Accommodation: Wire gauge range must support 14-30 AWG minimum
• Housing Material & Flammability: Polyamide construction with UL94 V-0 rating ensures safety compliance

The substitute part Phoenix Contact 1863259 maintains all critical electrical and mechanical parameters while offering an active product status with enhanced wire gauge accommodation (0.14-1.5mm²) and improved termination technology (Rising Cage Clamp).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1863259 is a direct functional substitute for the obsolete 5449089. Both components share identical electrical ratings (8A at 320V IEC), mechanical configuration (12 positions, 4.6mm pitch, 90° entry), and safety certifications (UL94 V-0). The 1863259 offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The 1863259 incorporates Rising Cage Clamp termination technology, which represents an enhancement over standard screw termination while maintaining M2 screw compatibility and identical torque specifications. The substitute accommodates a marginally wider wire gauge range at the lower end (0.14mm² versus 0.2mm²), providing additional flexibility for fine-gauge applications.

Both parts maintain equivalent insulation heights and contact mating finishes. The 1863259 carries ROHS3 compliance, meeting current regulatory requirements, while the 5449089 meets the earlier RoHS standard. Moisture sensitivity levels are identical at MSL 1 (Unlimited), indicating no special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1863259 directly replace the 5449089 in existing installations?

A: Yes. Both components maintain identical electrical ratings (8A at 320V IEC), 12-position configuration, 4.6mm pitch, and 90° wire entry orientation. Mechanical mounting and screw termination specifications are equivalent, enabling direct substitution without circuit redesign.

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

A: Rising Cage Clamp termination in the 1863259 provides an enhanced clamping mechanism while maintaining the same M2 screw interface and torque specifications (0.22-0.25 Nm) as the standard screw termination in the 5449089. Both termination methods are mechanically compatible with the same wire gauge range.

Q: Does the wire gauge range difference (0.2-1.5mm² versus 0.14-1.5mm²) affect compatibility?

A: No. The 1863259 accommodates a wider range at the lower end, making it suitable for applications using finer gauge wires. For applications within the 0.2-1.5mm² range, both parts perform identically.

Q: Are there packaging differences between these parts?

A: The 5449089 is supplied in standard packaging, while the 1863259 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional performance or electrical characteristics.

Q: What compliance certifications apply to both parts?

A: Both components meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings. The 1863259 carries ROHS3 compliance, while the 5449089 meets the earlier RoHS standard. Both are classified as EAR99 for export control purposes.

Q: Why is the 5449089 listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The Phoenix Contact 1863259 represents the active equivalent, ensuring continued component availability and supply chain continuity for new designs and system maintenance.
