Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646308 is determined by strict alignment with the following critical parameters:

Core Substitution Criteria:

• Connector type: Base - Box Mount configuration
• Connector size: B16
• Thread size: M32
• Housing material: Aluminum, Die Cast
• Operating temperature range: -40°C to 125°C minimum
• Manufacturer: Phoenix Contact HEAVYCON® series

The substitute part 1082587 qualifies as a direct equivalent based on matching all core mechanical and electrical parameters. While the substitute offers enhanced ingress protection (IP66/IP67 versus IP65) and dual side entry configuration, these represent functional improvements rather than deviations from the original specification. Both parts maintain identical thread sizing, connector size classification, and temperature operating ranges.

Engineering Selection Recommendations

The Phoenix Contact 1082587 serves as the direct substitute for the obsolete 1646308 connector base. Selection of the 1082587 is supported by the following engineering factors:

Product Status: The 1082587 maintains active product status with current manufacturing support, ensuring availability for replacement and new installations. The original 1646308 is obsolete and no longer supported by the manufacturer.

Compliance Certifications: Both parts maintain RoHS compliance. The 1082587 achieves ROHS3 compliance, representing current regulatory alignment. Both components carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Mechanical Compatibility: Identical M32 thread sizing, B16 connector size, and aluminum die-cast housing ensure direct mechanical interchangeability in box mount applications.

Environmental Performance: The 1082587 provides enhanced ingress protection at IP66/IP67 rating compared to the original IP65 specification, offering improved performance in demanding environmental conditions while maintaining full backward compatibility with existing mounting interfaces.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1082587 directly replace the 1646308 in existing installations?

A: Yes. Both components share identical mechanical mounting interfaces, M32 thread sizing, B16 connector size, and aluminum die-cast construction. The 1082587 is mechanically and electrically compatible with applications originally designed for the 1646308.

Q: What is the primary difference between these two connector bases?

A: The 1082587 features dual side entry configuration and enhanced ingress protection rating (IP66/IP67) compared to the single side entry and IP65 rating of the 1646308. Both maintain identical operating temperature ranges and core mechanical specifications.

Q: Are there packaging differences between the main part and substitute?

A: The 1646308 was supplied in standard packaging, while the 1082587 is available in bulk packaging. This represents a distribution format difference with no impact on component functionality or mechanical compatibility.

Q: Does the enhanced IP rating of the 1082587 affect compatibility?

A: No. Enhanced ingress protection represents a functional improvement and does not compromise compatibility. Applications requiring IP65 protection will operate correctly with the IP66/IP67-rated 1082587.

Q: What compliance standards apply to both connector bases?

A: Both components are RoHS compliant. The 1082587 achieves ROHS3 compliance, representing current environmental regulatory standards. Both carry identical ECCN and HTSUS classifications for export and tariff purposes.
