Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1677021 is determined by the following critical parameters:

• Manufacturer and Series Alignment: Both parts must originate from Phoenix Contact and belong to the HEAVYCON® A16 series to ensure mechanical and electrical compatibility within the connector ecosystem.
• Connector Type and Gender: Male insert connectors are required to maintain interface compatibility with existing mating female receptacles.
• Size and Termination Method: D25 size with screw termination ensures physical fit and installation compatibility.
• Voltage and Current Ratings: Substitute parts must meet or exceed the 600V voltage specification and 10A current requirement to support the electrical load.
• Operating Temperature Range: The -40°C to 125°C range must be maintained or exceeded.
• Material and Compliance Standards: Contact material (Copper Alloy with Silver finish), housing material properties, and UL94 V-0 flammability rating ensure consistent performance and safety.

The Phoenix Contact 1585317 qualifies as a direct substitute based on these parameters, with enhanced electrical capacity and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1585317 is the qualified substitute for the obsolete 1677021 connector. Selection rationale is based on the following factors:

Product Status: The 1585317 maintains active product status with Phoenix Contact, ensuring continued availability and supply chain reliability. The 1677021 is obsolete and no longer actively manufactured.

Electrical Performance: The 1585317 provides enhanced current capacity (19A versus 10A) while maintaining the same 600V voltage rating. This upgrade in current handling capability supports higher-load applications without compromising compatibility.

Compliance and Certifications: Both parts maintain UL94 V-0 flammability ratings and operate across the identical -40°C to 125°C temperature range. The 1585317 achieves ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance of the 1677021.

Mechanical Compatibility: Both connectors share D25 size specifications, screw termination methods, and HEAVYCON® A16 series designation, ensuring direct mechanical fit within existing connector assemblies.

Functional Enhancement: The addition of a ground position (16+Ground versus 16 positions) in the 1585317 provides enhanced grounding capability for improved signal integrity and safety in applications requiring dedicated ground connections.

Frequently Asked Questions (FAQ)

Q: Can the 1585317 directly replace the 1677021 in existing assemblies?

A: Yes. Both connectors share identical D25 size, screw termination, and HEAVYCON® A16 series specifications. The mechanical interface with mating female receptacles remains unchanged. The additional ground position in the 1585317 does not prevent installation in existing connector housings designed for 16-position inserts.

Q: What is the significance of the current rating increase from 10A to 19A?

A: The 1585317 supports higher electrical loads. Applications originally designed for 10A operation can be implemented with the 1585317 without modification. Applications requiring current levels between 10A and 19A can now be supported by the substitute part.

Q: Does the housing material change from Polyamide to Polycarbonate affect compatibility?

A: No. Both materials meet UL94 V-0 flammability requirements and maintain the same operating temperature range. Polycarbonate offers enhanced mechanical durability and environmental resistance compared to Polyamide.

Q: Are there packaging differences between these parts?

A: The 1677021 is supplied in standard packaging, while the 1585317 is supplied in bulk packaging. This difference affects order quantities and storage considerations but does not impact electrical or mechanical performance.

Q: What compliance advantage does ROHS3 provide over RoHS?

A: ROHS3 represents current regulatory compliance with the Restriction of Hazardous Substances Directive. The 1585317 meets contemporary environmental and safety standards, supporting long-term supply chain viability and regulatory alignment for new designs.
