Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449681 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: Plug with female sockets, 3-position, 0.150" (3.81mm) pitch
• Electrical Ratings: Minimum 8A current capacity (IEC) and 320V voltage rating (IEC)
• Mechanical Interface: 90° wire entry, free-hanging in-line mounting
• Termination Method: Screw-based connection system
• Material & Safety Compliance: Polyamide housing, UL94 V-0 flammability rating
• Wire Compatibility: Support for 14-30 AWG (0.2-1.5mm²) wire gauges

The substitute part Phoenix Contact 1828359 meets all critical substitution criteria. It maintains identical electrical ratings, connector geometry, pitch, and mounting configuration. The primary difference is the termination mechanism upgrade from standard screw to rising cage clamp screw, which represents an enhancement rather than a deviation. Wire gauge support extends to 0.14mm² minimum, providing broader compatibility. Both parts carry equivalent safety certifications and material specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1828359 is the qualified substitute for the obsolete 5449681. Selection is based on the following engineering criteria:

Product Status & Availability: The 5449681 is obsolete, while the 1828359 is active and maintains current manufacturing support. This ensures long-term availability and supply chain continuity.

Electrical & Mechanical Equivalence: Both parts maintain identical electrical ratings (8A IEC, 320V IEC), connector geometry (3-position, 3.81mm pitch), and mechanical interface (90° free-hanging in-line). Dimensional compatibility is confirmed through matching insulation height (0.752" / 19.10mm) and screw size (M2).

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and carry equivalent safety certifications. The 1828359 carries ROHS3 compliance, representing current regulatory alignment.

Termination Enhancement: The 1828359 features rising cage clamp screw termination with specified torque range (0.22-0.25 Nm), providing improved connection reliability compared to standard screw termination. This represents a functional upgrade without introducing incompatibility.

Wire Gauge Compatibility: The 1828359 extends minimum wire gauge support to 0.14mm², providing broader compatibility while maintaining the 14-30 AWG upper range. Existing installations using 0.2-1.5mm² wire remain fully compatible.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1828359 directly replace 5449681 in existing installations?

A: Yes. Both parts maintain identical pitch (3.81mm), connector type (3-position plug with female sockets), electrical ratings (8A/320V IEC), and mechanical mounting (90° free-hanging in-line). Physical and electrical compatibility is confirmed.

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

A: The 5449681 uses standard screw termination. The 1828359 uses rising cage clamp screw termination with specified torque (0.22-0.25 Nm). Rising cage clamp design provides enhanced connection security and repeatability. Both use M2 screws and are compatible with the same wire gauge range.

Q: Are there wire gauge compatibility differences?

A: The 1828359 supports 0.14-1.5mm² (14-30 AWG), while the 5449681 supports 0.2-1.5mm² (14-30 AWG). The 1828359 extends compatibility to smaller wire gauges. All wire sizes compatible with 5449681 are fully compatible with 1828359.

Q: What is the packaging difference?

A: The 5449681 packaging is not specified. The 1828359 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 5449681 is RoHS Compliant. The 1828359 is ROHS3 Compliant, representing current regulatory alignment. Both meet environmental compliance requirements.

Q: Why is 5449681 obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 1828359 (COMBICON MCVR series) represents the active equivalent within Phoenix Contact's current product portfolio, offering enhanced termination technology and maintained manufacturing support.
