Phoenix Contact 1679498 Heavy Duty Connector Insert - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1679498 is a male insert without contacts for heavy duty connectors, featuring 64 positions with crimp termination. This component is part of the HEAVYCON® D64 series and is currently classified as obsolete. Due to its discontinued status, identifying compatible substitute parts is essential for system maintenance, repair, and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1679498 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Series alignment: HEAVYCON® D64
• Connector type: Insert without Contacts
• Gender: Male
• Size: B24
• Termination style: Crimp
• Operating temperature range: -40°C to 125°C minimum
• Material flammability rating: UL94 V-0

Allowable Variations:

• Number of positions: The substitute may include additional positions (such as ground pins) provided the base 64-position configuration is maintained
• Voltage rating: The substitute may have a lower voltage rating if the application requirements permit
• Housing material: Alternative materials (such as Polyamide/Nylon) are acceptable if they meet the same flammability and environmental specifications
• Contact type: Different contact designations are acceptable if electrical and mechanical compatibility is preserved

The Phoenix Contact 1584431 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1584431 is the qualified substitute for the obsolete 1679498. Selection of this substitute is supported by the following factors:

Product Status: The 1584431 maintains active product status with Phoenix Contact, ensuring ongoing availability and supply chain continuity compared to the obsolete 1679498.

Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial applications.

Electrical Compatibility: The 1584431 operates at 250V with 10A current rating. Applications originally specified for the 1679498 at 600V must be evaluated to confirm that 250V operation is acceptable for the intended circuit.

Mechanical Compatibility: Both parts share identical size (B24), termination style (crimp), and operating temperature range (-40°C to 125°C), ensuring physical and thermal compatibility within existing connector assemblies.

Position Configuration: The 1584431 includes an additional ground position beyond the base 64-position configuration. This addition does not compromise compatibility with standard 64-position applications and may provide enhanced grounding capability in new designs.

Material Consideration: The housing material differs (Polycarbonate versus Polyamide/Nylon), but both materials meet the same flammability and environmental specifications required for heavy duty connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 1584431 directly replace the 1679498 in existing assemblies?

A: The 1584431 is mechanically and thermally compatible with the 1679498. However, the reduced voltage rating (250V versus 600V) must be evaluated against application requirements. If the original circuit operates below 250V, direct substitution is feasible. If higher voltage operation is required, alternative solutions must be explored.

Q: What is the significance of the additional ground position in the 1584431?

A: The 1584431 includes a dedicated ground position in addition to the 64 standard positions. This does not prevent its use in applications requiring only 64 positions, as the additional ground pin can remain unused or be utilized for enhanced grounding in new designs.

Q: Are there differences in contact type between these parts?

A: Yes. The 1679498 uses CK 1.6-BR and ER contact types, while the 1584431 uses CK 1.6-ED contacts. Both are compatible with crimp termination and the B24 size specification. Contact type selection should be confirmed with the connector housing and wire gauge specifications for the application.

Q: Does the housing material change affect performance?

A: Both Polycarbonate and Polyamide/Nylon housing materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-40°C to 125°C). Material selection is driven by specific environmental exposure and mechanical stress requirements; both materials are suitable for standard heavy duty connector applications.

Q: What is the inventory status for these parts?

A: The 1679498 (obsolete) has 706 pieces in stock. The 1584431 (active) has 1071 pieces in stock, providing greater availability for ongoing procurement needs.

Q: Are both parts RoHS and REACH compliant?

A: Both parts are ROHS3 compliant. The 1679498 is REACH Affected, while the 1584431 is REACH Unaffected. For applications subject to REACH regulations, the 1584431 may offer simplified compliance documentation.
