Phoenix Contact 1674561 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1674561 is a female insert connector with 6 positions and screw termination, part of the HEAVYCON® HS6 series for heavy-duty applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates across industrial temperature ranges and meets UL94 V-0 flammability standards, requiring substitutes that maintain equivalent electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1674561 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Series: HEAVYCON® HS6
• Connector Type: Insert
• Gender: Female
• Size: B16
• Termination Style: Screw
• Contact Material: Copper Alloy
• Contact Finish: Silver
• Flammability Rating: UL94 V-0

Allowable Variations:

• Number of Positions: 6 or 6+Ground (ground position addition does not affect primary circuit functionality)
• Voltage Rating: Equal to or greater than 500V
• Current Rating: Equal to or greater than 35A
• Housing Material: Alternative polymers meeting UL94 V-0 standard
• RoHS Compliance: RoHS Compliant or ROHS3 Compliant

The substitute part 1406533 meets all mandatory criteria and represents an active product with enhanced specifications, making it a valid replacement for the obsolete 1674561.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1406533 is the qualified substitute for the obsolete 1674561 based on the following engineering criteria:

Product Status & Availability: The 1406533 maintains active product status with 836 units in stock, ensuring supply chain continuity for applications currently using the obsolete 1674561. The 1674561, with only 1153 units remaining, will eventually reach end-of-life inventory depletion.

Electrical & Mechanical Compatibility: Both parts operate within the HEAVYCON® HS6 series using identical connector geometry (B16 size), termination method (screw), and contact specifications (copper alloy with silver finish). The 1406533 provides a 100V voltage rating increase (600V vs. 500V), representing enhanced performance margin without design modification requirements.

Compliance & Certification: Both parts meet UL94 V-0 flammability standards and maintain RoHS compliance. The 1406533 carries ROHS3 Compliant status, reflecting current regulatory alignment. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.8000) codes, simplifying procurement and regulatory documentation.

Position Configuration: The 1406533 includes a ground position (6+Ground) in addition to the standard 6 positions. This addition does not compromise compatibility with existing 6-position applications, as the ground contact provides supplementary functionality without interfering with primary circuit connections.

Housing Material Variation: The substitution introduces polycarbonate (PC) housing in place of polyamide (PA/Nylon). Both materials achieve UL94 V-0 rating and maintain equivalent mechanical performance across the specified operating temperature range (-40°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can the 1406533 directly replace the 1674561 in existing assemblies?

A: Yes. Both parts share identical series designation (HEAVYCON® HS6), connector type (insert), gender (female), size (B16), and termination method (screw). Electrical ratings of the 1406533 meet or exceed those of the 1674561, and both maintain UL94 V-0 flammability compliance.

Q: What is the significance of the 6+Ground position configuration in the 1406533?

A: The additional ground position provides a dedicated grounding contact. In applications using only the standard 6 positions, this contact remains unused without affecting circuit operation. Applications requiring ground connectivity benefit from the integrated contact.

Q: Are there differences in housing material between these parts?

A: Yes. The 1674561 uses polyamide (PA/Nylon) housing, while the 1406533 uses polycarbonate (PC). Both materials meet UL94 V-0 flammability standards and operate across the identical temperature range (-40°C to 125°C). Material selection does not impact electrical or mechanical compatibility.

Q: Does the higher voltage rating of the 1406533 (600V vs. 500V) require circuit redesign?

A: No. Higher voltage ratings provide increased safety margin and do not necessitate design changes. The 1406533 operates safely in applications designed for 500V operation.

Q: What is the inventory status for each part?

A: The 1674561 (obsolete) has 1153 units in stock. The 1406533 (active) has 836 units in stock. For long-term supply assurance, the 1406533 is the recommended selection.

Q: Are both parts RoHS compliant?

A: Yes. The 1674561 is RoHS Compliant. The 1406533 is ROHS3 Compliant, representing current regulatory standards. Both meet environmental compliance requirements.

Q: Can the 1406533 be used in new designs replacing the obsolete 1674561?

A: Yes. The 1406533 is the active product equivalent and is suitable for new design implementations. Its active status ensures long-term availability and technical support.
