Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1679524 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Manufacturer: Phoenix Contact
• Series: HEAVYCON® D25
• Connector Type: Insert without Contacts
• Gender: Female
• Size: D25
• Termination Style: Crimp
• Operating Temperature Range: -40°C to 125°C
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Number of Positions: 25 to 25+Ground (addition of ground position permitted)
• Voltage Rating: 600V to 250V (downward compatible)
• Current Rating: 10A (maintained)
• Housing Material: Polycarbonate (PC) to Polyamide (PA), Nylon (both UL94 V-0 rated)
• RoHS Status: RoHS Compliant to ROHS3 Compliant (forward compatible)

The substitute part 1679524 meets these criteria with the addition of a ground position and updated material composition while maintaining electrical performance and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1584402 is the designated substitute for the obsolete 1679524. Selection of this substitute is supported by the following factors:

Product Status: The 1584402 maintains active product status, ensuring continued availability and manufacturer support, whereas the 1679524 is obsolete.

Compliance and Certifications: Both parts maintain UL94 V-0 material flammability rating and unlimited moisture sensitivity level (MSL 1). The 1584402 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant status of the original part.

Electrical and Thermal Specifications: The 1584402 maintains the 10A current rating and -40°C to 125°C operating temperature range. The voltage rating reduction from 600V to 250V is acceptable for applications not requiring the higher voltage specification of the original part.

Mechanical Compatibility: Both parts share identical D25 size, female gender, crimp termination style, and HEAVYCON® D25 series designation. The addition of a ground position in the 1584402 provides enhanced grounding capability without compromising mechanical fit or connector interface.

Material Composition: The housing material change from Polycarbonate (PC) to Polyamide (PA), Nylon maintains the UL94 V-0 flammability rating and does not affect thermal or electrical performance within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the 1584402 directly replace the 1679524 in existing assemblies?

A: The 1584402 is mechanically and electrically compatible with the 1679524 within the specified parameters. Both parts share the same D25 size, female gender, crimp termination, and HEAVYCON® D25 series designation. The addition of a ground position and change in housing material do not prevent direct substitution. However, applications requiring the 600V rating of the original part must verify that the 250V rating of the 1584402 meets system requirements.

Q: What is the significance of the ground position addition in the 1584402?

A: The 1584402 includes a dedicated ground position (25+Ground) compared to the 25-position configuration of the 1679524. This addition provides a dedicated grounding path and does not affect mechanical compatibility or connector interface. Applications may utilize this ground position or leave it unconnected without impact to the substitute part's function.

Q: Are there packaging differences between these parts?

A: The 1679524 is listed with unspecified packaging, while the 1584402 is supplied in bulk packaging. Procurement specifications should account for bulk packaging requirements when ordering the substitute part.

Q: Does the housing material change from Polycarbonate to Polyamide affect performance?

A: Both materials maintain UL94 V-0 flammability rating and are suitable for the -40°C to 125°C operating temperature range. The Polyamide (PA), Nylon housing of the 1584402 does not degrade electrical or thermal performance compared to the Polycarbonate (PC) housing of the original part.

Q: What compliance certifications apply to the 1584402?

A: The 1584402 carries ROHS3 compliance and maintains UL94 V-0 material flammability rating. The part is REACH Unaffected, indicating no restrictions under REACH regulations. These certifications align with current regulatory requirements for heavy-duty connector applications.
