Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449076 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 11
• Pitch: 0.138" (4.60mm)
• Type: Plug, Female Sockets
• Plug wire entry orientation: 90°
• Mounting type: Free Hanging (In-Line)
• Current rating: 8A (IEC/UL)
• Voltage rating: 320V (IEC) / 300V (UL)
• Termination style: Screw-based
• Wire gauge compatibility: 14-30 AWG (0.2-1.5mm²)
• Housing material: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0
• RoHS compliance: Required

The substitute part Phoenix Contact 1863246 meets all mandatory matching parameters. The primary difference is the termination mechanism upgrade from standard screw to rising cage clamp screw, which provides enhanced wire retention. The insulation height differs (0.752" vs 0.492"), and the minimum wire gauge extends to 0.14mm², representing improved compatibility with finer conductors.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1863246 is a direct functional substitute for the obsolete 5449076. Both components maintain identical electrical specifications (8A/320V IEC, 8A/300V UL), mechanical pitch (4.60mm), and positional configuration (11-position plug with female sockets). Both are RoHS compliant and carry UL94 V-0 flammability certification.

The 1863246 is classified as active product status, ensuring ongoing availability and supply chain continuity. The rising cage clamp termination mechanism in the 1863246 represents a design enhancement over the standard screw termination of the 5449076, providing improved wire retention characteristics. The increased insulation height (0.752" vs 0.492") and extended minimum wire gauge compatibility (0.14mm² vs 0.2mm²) do not restrict substitution but rather expand application flexibility.

For applications currently using the 5449076, transition to the 1863246 is supported by identical mounting geometry, wire entry orientation, and electrical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1863246 directly replace the 5449076 in existing installations?

A: Yes. Both components share identical pitch (4.60mm), position count (11), wire entry angle (90°), electrical ratings (8A/320V IEC), and mounting configuration (free-hanging in-line). The 1863246 is mechanically and electrically compatible with systems designed for the 5449076.

Q: What is the primary difference between these two parts?

A: The termination mechanism differs. The 5449076 uses standard screw termination, while the 1863246 employs rising cage clamp screw termination. This enhancement improves wire retention without affecting electrical or mechanical compatibility.

Q: Are there any dimensional constraints I should consider?

A: The insulation height differs between the two parts (0.492" for 5449076 vs 0.752" for 1863246). Verify that the increased height of the 1863246 does not conflict with space constraints in your enclosure or panel layout.

Q: Does the 1863246 support the same wire gauge range?

A: The 1863246 supports an extended minimum wire gauge (0.14mm² vs 0.2mm²) while maintaining the same maximum (1.5mm²). This provides greater flexibility for finer conductor applications. Both parts support 14-30 AWG.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5449076 and 1863246 are RoHS compliant with UL94 V-0 flammability certification and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the product status difference, and why does it matter?

A: The 5449076 is obsolete, while the 1863246 is active. Active status ensures continued manufacturing, availability, and supply chain support for the 1863246, making it the recommended choice for new designs and ongoing system maintenance.
