Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1674574 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the HEAVYCON® HS6 series to ensure mechanical and electrical interchangeability within the connector system
• Connector Type & Gender: Insert configuration and male gender must be maintained
• Size Classification: B16 size designation must be preserved for proper mating and housing compatibility
• Termination Method: Screw termination style must be consistent
• Electrical Ratings: Substitute parts must meet or exceed the 500V voltage rating and 35A current capacity
• Operating Temperature Range: The -40°C to 125°C range must be supported
• Material Specifications: Contact material (Copper Alloy with Silver finish) and housing material properties must be compatible
• Flammability & Compliance: UL94 V-0 rating and RoHS compliance are mandatory

The substitute part 1406534 qualifies based on these parameters while offering enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1406534 serves as the direct substitute for the obsolete 1674574 within the HEAVYCON® HS6 series. Selection of the substitute part is supported by the following factors:

Product Status: The 1674574 is classified as obsolete, creating supply chain risk. The 1406534 maintains active product status, ensuring long-term availability and continued manufacturer support.

Compliance & Certifications: Both parts maintain UL94 V-0 flammability ratings and meet RoHS requirements. The 1406534 carries ROHS3 compliance and REACH affected status, reflecting current regulatory standards.

Electrical Performance: The 1406534 provides enhanced voltage rating (600V versus 500V) while maintaining the 35A current capacity. This represents a performance upgrade suitable for applications requiring the original 500V specification.

Mechanical Compatibility: Both parts share identical series designation, connector type, gender, size classification (B16), and screw termination method, ensuring direct mechanical interchangeability.

Position Configuration: The 1406534 includes a dedicated ground position (6+Ground) in addition to the 6 standard positions. Applications utilizing only the 6 standard positions remain fully compatible.

Material Consideration: The housing material differs (Polyamide in the original versus Polycarbonate in the substitute). Both materials maintain UL94 V-0 rating and support the identical operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 1406534 directly replace the 1674574 in existing installations?

A: Yes. Both parts share the same series (HEAVYCON® HS6), connector type (Insert), gender (Male), size (B16), and termination method (Screw). Mechanical and electrical interchangeability is maintained. The 1406534 provides enhanced voltage rating (600V) and active product status.

Q: What is the significance of the "6+Ground" position configuration in the 1406534?

A: The 1406534 includes six standard signal positions plus one dedicated ground position. Applications using only the six standard positions of the 1674574 remain fully compatible, with the ground position available for optional use.

Q: Are there compliance differences between these parts?

A: Both parts maintain UL94 V-0 flammability rating and RoHS compliance. The 1406534 carries ROHS3 compliance and is REACH affected, reflecting current regulatory frameworks. The 1674574 is listed as RoHS Compliant under earlier standards.

Q: Does the housing material change affect performance?

A: Both housing materials (Polyamide and Polycarbonate) maintain UL94 V-0 rating and support the identical -40°C to 125°C operating temperature range. Material selection does not impact electrical or thermal performance within specified parameters.

Q: What is the packaging difference?

A: The 1674574 is supplied in standard packaging, while the 1406534 is supplied in bulk packaging. Bulk packaging is typical for active production parts and does not affect component specifications or performance.

Q: Why is the 1674574 classified as obsolete?

A: Obsolescence reflects manufacturer discontinuation of this specific part number. The 1406534 represents the current active equivalent within the HEAVYCON® HS6 series, ensuring continued supply chain access and manufacturer support.
