Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5438281 is determined by the following critical parameters:

• Position Count & Pitch: 13 positions at 0.200" (5.08mm) spacing
• Connector Type: Plug with female sockets
• Wire Entry Angle: 90° free-hanging in-line configuration
• Electrical Ratings: Current and voltage specifications per IEC and UL standards
• Wire Gauge Compatibility: 12-30 AWG (0.2-2.5mm²)
• Termination Interface: Screw-based connection method
• Compliance Standards: UL94 V-0 flammability rating and RoHS compliance

The substitute part Phoenix Contact 1783193 maintains compatibility across all critical mechanical and electrical parameters, with the primary distinction being the termination mechanism upgrade from standard screw to rising cage clamp technology and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1783193 serves as the active equivalent for the obsolete 5438281. Both components maintain identical mechanical compatibility and wire gauge specifications. The 1783193 is classified as active product status, ensuring continued availability and supply chain support.

Key compliance factors are equivalent: both parts meet UL94 V-0 flammability requirements and RoHS compliance standards. The 1783193 features rising cage clamp termination technology, which represents a design enhancement over the standard screw termination of the 5438281, while maintaining the same M3 screw size and torque specifications.

Electrical parameter differences exist in IEC voltage rating (630 V vs. 320 V) and UL current rating (12 A vs. 15 A). These differences do not preclude substitution in applications operating within the lower specification envelope. Applications requiring the full 630 V IEC rating must retain the original 5438281 specification or identify alternative solutions outside the provided substitute list.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1783193 directly replace 5438281 in existing installations?

A: Mechanical and wire gauge compatibility is maintained. The 1783193 features rising cage clamp termination versus standard screw termination on the 5438281. Both use M3 screws with identical torque specifications (0.5-0.6 Nm). Verify application voltage requirements do not exceed 320 V IEC rating of the 1783193.

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

A: The 5438281 uses standard screw termination, while the 1783193 uses rising cage clamp technology. The 1783193 is active product status; the 5438281 is obsolete. Both maintain 13-position, 0.200" (5.08mm) pitch configuration with identical wire gauge support (12-30 AWG / 0.2-2.5mm²).

Q: Are the electrical ratings compatible for all applications?

A: Both parts support 12 A current at 300 V UL rating. The 5438281 supports 630 V IEC; the 1783193 supports 320 V IEC. Applications requiring 630 V IEC operation must use the original 5438281 specification.

Q: What packaging is available for each part?

A: The 5438281 is supplied in standard packaging. The 1783193 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5438281 and 1783193 are RoHS compliant with MSL rating of 1 (Unlimited).
