Phoenix Contact 5449063 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5449063 is a 10-position terminal block plug with female sockets, 0.138" (4.60mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 8A at 320V (IEC) and 8A at 300V (UL), and accommodates wire gauges from 14-30 AWG (0.2-1.5mm²). The part is currently obsolete, making substitute components necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449063 is determined by strict alignment of the following critical parameters:

Connector Type & Configuration: 10-position female socket plug with 0.138" (4.60mm) pitch spacing
Electrical Ratings: Minimum 8A current capacity and 320V voltage rating (IEC standard)
Mechanical Interface: 90° wire entry orientation, free-hanging in-line mounting
Termination Method: Screw-based wire connection system
Material & Safety Compliance: Polyamide housing with UL94 V-0 flammability rating
Wire Compatibility: Support for 14-30 AWG wire gauge range

The Phoenix Contact 1863233 meets all substitution criteria as an active product with identical electrical ratings, connector geometry, and mechanical compatibility. The primary difference lies in the termination mechanism (rising cage clamp versus standard screw) and enhanced wire gauge support (0.14-1.5mm² versus 0.2-1.5mm²), both of which maintain backward compatibility.

Engineering Selection Recommendations

The Phoenix Contact 1863233 is the direct substitute for the obsolete 5449063. Both components share identical electrical specifications (8A/320V IEC, 8A/300V UL), mechanical configuration (10-position, 4.60mm pitch, 90° entry), and safety certifications (UL94 V-0). The 1863233 is currently in active production status with enhanced RoHS3 compliance and REACH unaffected designation, providing superior long-term supply chain availability.

The rising cage clamp termination on the 1863233 offers improved wire retention compared to standard screw termination, while maintaining the same M2 screw torque specification (0.22-0.25 Nm). The extended wire gauge support (0.14-1.5mm² versus 0.2-1.5mm²) on the substitute provides additional flexibility for smaller conductor applications without compromising compatibility with the original 0.2-1.5mm² range.

The increased insulation height on the 1863233 (0.752" versus 0.492") does not affect functional compatibility in standard free-hanging applications but should be verified in space-constrained mounting environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1863233 directly replace the 5449063 in existing assemblies?

A: Yes. Both components feature identical 10-position, 4.60mm pitch female socket plugs with 90° wire entry, matching electrical ratings (8A/320V IEC), and equivalent mechanical mounting as free-hanging in-line connectors. The rising cage clamp termination on the 1863233 is functionally compatible with screw-terminated mating receptacles.

Q: What is the significance of the different insulation heights (12.50mm versus 19.10mm)?

A: Insulation height affects the overall profile of the connector assembly. The 1863233's increased height (19.10mm) provides additional creepage distance and may impact fit in applications with strict height constraints. Verify mounting clearance in confined spaces before substitution.

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

A: No. The 1863233 supports a broader wire gauge range that includes the original 0.2-1.5mm² specification. Applications using the original 5449063 wire gauge range remain fully compatible with the 1863233.

Q: Are there compliance differences between the two parts?

A: The 1863233 carries ROHS3 Compliant and REACH Unaffected designations, representing current regulatory compliance standards. The 5449063 is RoHS Compliant. Both maintain UL94 V-0 flammability ratings and EAR99 export classification.

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

A: Both are screw-based wire connection methods. Rising cage clamp termination provides automatic wire positioning and improved retention during insertion, while standard screw termination requires manual wire alignment. Both achieve equivalent electrical and mechanical performance when properly torqued to 0.22-0.25 Nm.
