Phoenix Contact 5437583 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5437583 is a 4-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 300V (UL), and accommodates wire gauges from 14-30 AWG (0.2-1.5mm²). The part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5437583 is determined by the following critical parameters:

• Connector Type & Gender: Must be a plug with female sockets to maintain mating compatibility with existing receptacles
• Position Count: 4-position configuration is mandatory for pin-to-pin correspondence
• Pitch Tolerance: The 0.138" (4.60mm) pitch defines the physical spacing; substitute parts with different pitch values (such as 0.150" / 3.81mm) represent a different connector family and are not direct mechanical substitutes
• Wire Entry Angle: 90° free-hanging in-line orientation must be preserved
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements (minimum 8A, 320V IEC or 300V UL)
• Wire Gauge Compatibility: Acceptable wire range must overlap with or encompass 14-30 AWG (0.2-1.5mm²)
• Termination Method: Screw-based termination is the specified interface
• Compliance & Certifications: RoHS compliance and UL94 V-0 flammability rating must be maintained

The substitute part Phoenix Contact 1710703 differs in pitch specification (0.150" vs. 0.138"), termination mechanism (Rising Cage Clamp vs. standard screw), and voltage rating (160V IEC vs. 320V IEC). These differences place it in a separate connector family and disqualify it as a direct mechanical or electrical substitute for the 5437583.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 5437583 is classified as obsolete. When sourcing replacement components, the following criteria apply:

Direct Substitution: No direct mechanical or electrical substitute exists within the provided data. The listed part 1710703 is not a direct substitute due to incompatible pitch (0.150" vs. 0.138"), different termination mechanism (Rising Cage Clamp vs. standard screw), and reduced IEC voltage rating (160V vs. 320V).

Compliance Considerations: Both parts maintain RoHS compliance and UL94 V-0 flammability certification. The 5437583 remains compliant for applications where the specific pitch and voltage rating are non-negotiable design requirements.

Product Status Impact: The active status of part 1710703 provides supply continuity, but its dimensional and electrical differences require complete system re-evaluation before implementation.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1710703 replace the 5437583 in existing installations?

A: No. The 1710703 has a different pitch (0.150" vs. 0.138"), which prevents mechanical mating with receptacles designed for the 5437583. Additionally, the IEC voltage rating is reduced from 320V to 160V, and the termination mechanism differs (Rising Cage Clamp vs. standard screw).

Q: What makes pitch a critical substitution parameter?

A: Pitch defines the center-to-center spacing between connector positions. A 0.012" (0.31mm) difference between 4.60mm and 3.81mm pitch is sufficient to prevent proper alignment and mating with corresponding receptacles. Connectors with different pitches belong to separate families and are not interchangeable.

Q: Is the 5437583 still available despite being obsolete?

A: According to inventory data, 851 pieces of the 5437583 are currently in stock as new original components. Obsolete status indicates that the manufacturer has discontinued production, but existing stock may remain available through authorized distributors.

Q: How do termination style differences affect substitution?

A: The 5437583 uses standard screw termination, while the 1710703 uses a Rising Cage Clamp mechanism. These are distinct wire-entry systems requiring different installation procedures and tooling. They are not interchangeable without modifying the mating receptacle or harness assembly.

Q: What voltage rating should I use for application selection?

A: For IEC applications, the 5437583 is rated at 320V. For UL applications, both the 5437583 and 1710703 are rated at 300V. Always verify that the selected component meets or exceeds your specific application voltage requirements.
