Key Parameters

Substitute Part Grouping Explanation

Substitution of heavy duty connector contacts is determined by compatibility across the following critical parameters:

• Contact Type & Termination Method: Both the main part and substitute must be socket contacts with crimp termination to ensure mechanical and electrical compatibility within the connector assembly.
• Wire Gauge Range: The wire gauge specification determines the contact's current-carrying capacity and mechanical fit. The main part accommodates 16-18 AWG wire.
• Contact Finish Material: Contact finish affects electrical conductivity, corrosion resistance, and contact resistance characteristics.
• Series Compatibility: Components within the same or compatible series maintain dimensional and functional consistency.
• Compliance & Product Status: Active substitute parts with current certifications provide long-term availability and support.

The Phoenix Contact 1004366 is identified as a substitute based on its classification as a crimp socket contact within the Phoenix Contact heavy duty connector portfolio, with overlapping wire gauge capability (14-16 AWG) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1004366 is an active substitute for the obsolete 1772544. Both components share the fundamental characteristics of stamped crimp socket contacts within the Phoenix Contact heavy duty connector ecosystem. The 1004366 maintains RoHS compliance through ROHS3 certification and is currently in active production status, ensuring availability for new designs and replacement applications.

The wire gauge specifications differ between the two parts: the 1772544 is rated for 16-18 AWG, while the 1004366 accommodates 14-16 AWG wire. This overlap in the 16 AWG range provides functional compatibility for applications within this shared specification window. The contact finish differs (silver versus nickel silver), which affects contact resistance and corrosion characteristics but does not preclude substitution in equivalent electrical applications.

Selection of the 1004366 as a replacement for the 1772544 is supported by active product status, current compliance certifications, and documented availability in inventory.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1004366 directly replace the 1772544 in all applications?

A: Both components are stamped crimp socket contacts within the Phoenix Contact heavy duty connector family. Compatibility depends on the specific wire gauge requirements of your application. The 1004366 is rated for 14-16 AWG wire, while the 1772544 is rated for 16-18 AWG. Applications using 16 AWG wire fall within both specifications and are compatible. Applications requiring 17-18 AWG wire are outside the 1004366 specification range.

Q: What is the significance of the contact finish difference between silver and nickel silver?

A: Contact finish material affects electrical conductivity and corrosion resistance. Silver provides excellent electrical conductivity and is commonly used in high-reliability applications. Nickel silver offers good conductivity with enhanced corrosion resistance. Both finishes are suitable for heavy duty connector applications; the choice depends on environmental exposure and performance requirements specific to your application.

Q: Why is the 1772544 listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production and support for this component. The 1004366 is an active alternative that provides equivalent functionality with current manufacturing support and compliance certifications.

Q: Are there packaging differences between these parts?

A: The 1772544 packaging is not specified in the available data. The 1004366 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What compliance certifications apply to each part?

A: The 1772544 is RoHS Compliant. The 1004366 is ROHS3 Compliant and REACH Unaffected, providing current regulatory compliance for EU and international markets.
