Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1679456 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Series: HEAVYCON® D7
• Connector Type: Insert without Contacts
• Gender: Male
• Number of Positions: 7+Ground
• Size: D7
• Termination Style: Crimp
• Current Rating: 10A
• Operating Temperature Range: -40°C to 125°C
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Voltage Rating: May be lower than 600V (substitute must meet or exceed application requirements)
• Housing Material: May differ while maintaining UL94 V-0 compliance
• Contact Type: May differ based on crimp termination compatibility
• RoHS Status: May be ROHS3 Compliant (more stringent than RoHS Compliant)
• Product Status: Active status preferred for obsolete parts

The substitute part 1584334 maintains all mandatory matching parameters while offering active product status and enhanced RoHS compliance, making it a valid equivalent for the obsolete 1679456.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1584334 serves as the active equivalent for the obsolete 1679456. Both components share identical mechanical and electrical specifications for the HEAVYCON® D7 series, including connector type, gender, position count, size, termination method, current rating, and operating temperature range.

The 1584334 provides enhanced compliance status through ROHS3 certification, which supersedes the RoHS Compliant designation of the original part. Both components maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels.

The primary electrical difference is the voltage rating: the 1584334 is rated for 250V compared to the 1679456's 600V rating. Component selection should be based on the actual voltage requirements of the application. For applications requiring 600V operation, the voltage rating difference must be evaluated against system design specifications.

The housing material differs between the two parts—PBTP in the original versus polyamide (PA) nylon in the substitute—while both maintain equivalent flammability performance. This material change does not affect mechanical compatibility or electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1584334 directly replace the 1679456 in all applications?

A: The 1584334 is mechanically and electrically compatible with the 1679456 for applications operating at 250V or below. If your application requires 600V operation, the voltage rating difference must be evaluated against your system specifications before substitution.

Q: What is the significance of the housing material change from PBTP to polyamide?

A: Both materials maintain UL94 V-0 flammability ratings and are suitable for the HEAVYCON® D7 series. The material change does not affect mechanical fit, electrical performance, or operating temperature range. Material selection may be driven by manufacturing availability and cost optimization.

Q: Why is the 1679456 listed as obsolete?

A: The 1679456 has been superseded by the 1584334 in Phoenix Contact's product portfolio. The 1584334 offers active product status, enhanced ROHS3 compliance, and equivalent performance for the HEAVYCON® D7 series applications.

Q: Are there any compatibility concerns with the contact type difference between CK 1.6-ER and CK 1.6-ED?

A: Both contact types are crimp-terminated variants within the HEAVYCON® D7 series. The specific contact type designation reflects manufacturing updates while maintaining compatibility with the D7 insert specifications.

Q: What is the inventory status for these parts?

A: The 1679456 has 987 pieces in stock as new original inventory. The 1584334 has 1015 pieces in stock as new original inventory in bulk packaging. Availability should be confirmed with your supplier for current stock levels.

Q: Does the ROHS3 compliance of the 1584334 affect compatibility with existing systems?

A: ROHS3 compliance is a more stringent environmental standard than RoHS Compliant. The 1584334 meets or exceeds all environmental requirements of the original 1679456 and is fully compatible with existing HEAVYCON® D7 system designs.
