Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1773093 is determined by the following critical parameters:

• Series compatibility: HEAVYCON® A3
• Connector type: Insert
• Gender: Female
• Size: D7
• Termination style: Screw
• Voltage rating: Minimum 600V
• Operating temperature range: -40°C to 125°C or broader
• Contact material and finish: Copper Alloy with Silver finish
• Flammability rating: UL94 V-0

The Phoenix Contact 1585223 qualifies as a substitute based on these core compatibility criteria. While the 1585223 offers enhanced specifications (24A current rating versus 10A, and includes a ground position), it maintains full compatibility with the mechanical and electrical envelope of the original part within the HEAVYCON® A3 series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1585223 is the designated substitute for the obsolete 1773093. Selection of the 1585223 is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance exceeds the RoHS compliance of the original part, meeting current regulatory requirements
• Identical mechanical interface (D7 size, HEAVYCON® A3 series) ensures direct physical compatibility
• Equivalent voltage and temperature ratings maintain operational envelope compatibility
• Enhanced current rating (24A versus 10A) provides increased capacity without compromising the original application requirements
• Polycarbonate housing material offers improved durability compared to polyamide

The addition of a ground position in the 1585223 does not preclude its use in applications requiring only three positions; the ground contact can remain unused in such configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1585223 directly replace the 1773093 in existing assemblies?

A: Yes. Both parts share identical mechanical dimensions (D7 size), series designation (HEAVYCON® A3), and core electrical specifications (600V, -40°C to 125°C). The 1585223 maintains full physical and electrical compatibility.

Q: What is the significance of the additional ground position in the 1585223?

A: The 1585223 includes a dedicated ground position, increasing total positions from 3 to 3+Ground. In applications requiring only three signal or power connections, the ground contact remains available but unused, presenting no functional impact.

Q: How do the current ratings differ, and does this affect substitution?

A: The 1773093 is rated for 10A, while the 1585223 is rated for 24A. The higher current rating of the substitute part does not restrict its use in lower-current applications. The 1585223 remains fully compatible with circuits designed for 10A operation.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current regulatory standard for Restriction of Hazardous Substances, incorporating updated substance restrictions. The 1585223 meets ROHS3 requirements, ensuring compliance with current and future regulatory frameworks.

Q: Are there packaging differences between these parts?

A: The 1773093 is supplied in standard packaging, while the 1585223 is supplied in bulk packaging. Bulk packaging does not affect component functionality or electrical characteristics.

Q: Why is the 1773093 classified as obsolete?

A: Obsolescence indicates that Phoenix Contact has discontinued production of this part number. The 1585223 represents the active product line continuation within the HEAVYCON® A3 series, ensuring long-term availability for new designs and maintenance applications.
