Phoenix Contact 1594801 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1594801 is a 7-position circular connector insert with female sockets and screw termination. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system maintenance and new designs. The insert is designed for use within the RC series connector family and requires a compatible shell assembly for complete connector functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1594801 is determined by the following critical parameters that must remain consistent:

• Series Compatibility: Both parts must belong to the RC series to ensure mechanical and electrical interchangeability within the connector family
• Connector Configuration: Female socket insert type with 7-position power rating
• Contact System: Gold-plated mating surface with copper zinc contact material ensures equivalent electrical performance and corrosion resistance
• Orientation: Normal (N) orientation maintains directional compatibility
• Compliance Standards: RoHS compliance and MSL rating of 1 (Unlimited) ensure regulatory and environmental compatibility

The primary differentiator between the main part and its substitute is the termination method: screw termination versus solder cup termination. This distinction affects only the wire attachment methodology and does not impact the insert's core electrical or mechanical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1594558 serves as the direct substitute for the obsolete 1594801 insert. Both components maintain identical electrical and mechanical interface specifications within the RC series connector family, including the 7-position power configuration, gold-plated contact finish, and normal orientation.

The 1594558 is classified as an active product with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete status of the 1594801. The termination method difference—solder cup versus screw—represents the only functional distinction and should be evaluated based on the specific assembly and maintenance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1594558 be used as a direct replacement for the 1594801 in existing assemblies?

A: The 1594558 maintains identical electrical and mechanical interface characteristics within the RC series. Compatibility depends on whether the assembly can accommodate solder cup termination in place of screw termination. The connector shell and mating interface remain unchanged.

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

A: Screw termination (1594801) uses mechanical fastening for wire attachment, while solder cup termination (1594558) requires soldering. The choice depends on assembly methodology, maintenance accessibility, and application requirements. Both methods provide equivalent electrical performance.

Q: Are there compliance differences between these parts?

A: The 1594801 is RoHS Compliant, while the 1594558 is ROHS3 Compliant. Both maintain MSL rating of 1 (Unlimited). The 1594558 additionally carries REACH Affected status. Both meet the regulatory requirements for their respective product lifecycles.

Q: Why is the 1594801 classified as obsolete?

A: Obsolescence typically reflects end-of-life status from the manufacturer. The 1594558 represents the active product line continuation within the RC series and should be specified for new designs and long-term availability assurance.

Q: Does the insert material specification affect substitution?

A: The 1594558 specifies Polybutylene Terephthalate (PBT) insert material. This material is standard for the active RC series product line and maintains compatibility with all RC series shell assemblies. The 1594801 insert material is not specified in available documentation.
