Phoenix Contact 1593555 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1593555 is a 6-position circular connector insert with male pins and screw termination. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The insert is designed for use within circular connector shells and requires a compatible shell assembly for complete connector functionality. As an insert-only component, substitution must account for termination method compatibility and electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1593555 is determined by the following critical parameters:

• Connector Type & Position Count: Both the main part and substitute must be insert-type male pin connectors with 6 positions to maintain mechanical and electrical compatibility within existing shell assemblies.
• Series Compatibility: Both components belong to the Phoenix Contact RC series, ensuring dimensional and interface consistency.
• Orientation: Normal (N) orientation must be maintained for proper mating alignment.
• Contact Finish & Material: Gold-plated copper zinc contacts ensure consistent electrical performance and corrosion resistance across substitutions.
• Insert Material: Polybutylene Terephthalate (PBT) provides equivalent mechanical and thermal stability.
• Compliance & Certification: RoHS compliance and MSL rating of 1 (Unlimited) must be preserved for regulatory and environmental requirements.

The primary differentiator between the main part and its substitute is the termination method: the 1593555 uses screw termination, while the substitute employs solder cup termination. This distinction affects installation methodology but does not compromise functional compatibility when the appropriate termination technique is applied.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1593072 is the designated substitute for the obsolete 1593555. Both components maintain identical mechanical and electrical specifications across all critical parameters: 6-position male pin configuration, RC series compatibility, normal orientation, gold-plated copper zinc contacts, and PBT insert material.

The 1593072 holds active product status, ensuring continued availability and supply chain reliability. Both parts maintain full RoHS compliance and MSL rating of 1 (Unlimited), satisfying regulatory and environmental requirements without modification.

The termination method difference—screw versus solder cup—represents the only functional distinction. This change requires corresponding modification to the cable termination process but does not affect connector shell compatibility, pin configuration, or electrical performance. The 1593072 provides documented operating temperature range of -40°C to 125°C, offering explicit thermal performance specification.

Frequently Asked Questions (FAQ)

Q: Can the 1593072 be used as a direct replacement for the 1593555 in existing assemblies?

A: The 1593072 is mechanically and electrically compatible with existing RC series shells designed for the 1593555. The primary consideration is termination method: the 1593555 uses screw termination while the 1593072 uses solder cup termination. Cable connections must be prepared accordingly.

Q: What is the significance of the termination method difference?

A: Screw termination (1593555) involves mechanical fastening of conductors under a screw clamp. Solder cup termination (1593072) requires soldering of conductors into the cup receptacle. Both methods achieve equivalent electrical connection when properly executed. Selection depends on available assembly equipment and process requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1593555 and 1593072 are RoHS compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Why is the 1593555 listed as obsolete?

A: The 1593555 has been discontinued by Phoenix Contact. The 1593072 represents the active product line continuation within the RC series, providing equivalent functionality with solder cup termination.

Q: Does the operating temperature specification difference affect substitution?

A: The 1593072 provides explicit operating temperature range of -40°C to 125°C. The 1593555 does not specify operating temperature in available documentation. For applications requiring confirmed thermal performance, the 1593072 offers documented specification.

Q: Are the contact materials identical?

A: Yes. Both parts use copper zinc contact material with gold plating for mating surfaces, ensuring equivalent electrical conductivity and corrosion resistance.
