Phoenix Contact 1679546 Female Insert 64-Position Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1679546 is a female insert connector without contacts, designed for 64-position crimp termination in 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 HEAVYCON® D64 series insert provides electrical connectivity in industrial environments with a 600V voltage rating and 10A current capacity per contact.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1679546 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Series alignment (HEAVYCON® D64)
• Connector type (Insert without Contacts)
• Gender (Female)
• Size designation (B24)
• Termination method (Crimp)
• Operating temperature range (-40°C to 125°C)
• Material flammability rating (UL94 V-0)
• RoHS3 compliance

Secondary Consideration Parameters:

• Position count and configuration
• Voltage and current ratings
• Contact type specifications
• Housing material composition

The substitute part 1584444 maintains compatibility within the HEAVYCON® D64 series while introducing a modified position configuration (64+Ground) and alternative contact specifications. Voltage rating reduction from 600V to 250V and housing material change from polycarbonate to polyamide represent functional modifications that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1584444 is the designated substitute for the obsolete 1679546 within the HEAVYCON® D64 series. Both components maintain identical operating temperature ranges, current ratings, and flammability certifications. The substitute part carries active product status with current manufacturing availability, addressing the obsolescence of the original component.

Key differences requiring application assessment:

Voltage Rating: The substitute operates at 250V compared to the original 600V specification. Applications requiring voltages exceeding 250V cannot use this substitute without system redesign.

Position Configuration: The addition of a dedicated ground position (64+Ground versus 64) provides enhanced grounding capability in the substitute design. This modification may require connector interface adjustments in existing installations.

Housing Material: Polyamide/nylon housing in the substitute replaces polycarbonate in the original. Both materials maintain UL94 V-0 flammability compliance and support the full operating temperature range.

Contact Type: Contact specification change from CK 1.6-BR, ER to CK 1.6-ED reflects design evolution within the series. Compatibility with existing crimp contact tooling and mating components must be confirmed.

Both components maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1584444 directly replace the 1679546 in existing installations?

A: Direct replacement requires confirmation that application voltage does not exceed 250V and that the 64+Ground position configuration is compatible with existing connector interfaces and wiring harnesses.

Q: What is the significance of the 64+Ground position configuration in the substitute?

A: The dedicated ground position provides a separate grounding path within the connector insert, potentially improving grounding reliability in applications where ground distribution is critical.

Q: Are the crimp contact types interchangeable between these two parts?

A: The contact type change from CK 1.6-BR, ER to CK 1.6-ED indicates design modification. Existing crimp tooling and contact inventory must be evaluated for compatibility with the substitute contact specification.

Q: Does the housing material change affect environmental performance?

A: Both polycarbonate and polyamide housing materials maintain UL94 V-0 flammability ratings and support the identical -40°C to 125°C operating temperature range. Material selection should be evaluated based on specific chemical exposure and mechanical stress requirements in the application environment.

Q: Why is the original 1679546 classified as obsolete?

A: Obsolescence reflects Phoenix Contact's product lifecycle management. The 1584444 represents the current generation design within the HEAVYCON® D64 series, incorporating design improvements and enhanced grounding capability.

Q: Are there inventory considerations for the substitute part?

A: The 1584444 is in active production with 943 pieces currently available in stock, compared to the obsolete 1679546 with limited remaining inventory of 1124 pieces. Long-term availability favors the active substitute part.
