Phoenix Contact 1646285 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646285 is a heavy duty connector base designed for box mount, side entry applications with M25 thread size and B10 form factor. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations where this connector type is specified.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646285 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector type: Base - Box mount configuration
• Style: Side entry orientation
• Size designation: B10 form factor
• Thread size: M25
• Operating temperature range: -40°C to 125°C minimum
• Housing material: Aluminum die cast construction
• RoHS compliance status

The substitute part 1082578 maintains all core compatibility parameters while providing enhanced ingress protection (IP66/IP67 versus IP65) and dual side entry configuration. The dimensional similarity and identical thread size ensure mechanical compatibility in existing mounting applications.

Engineering Selection Recommendations

The Phoenix Contact 1082578 serves as the direct substitute for the obsolete 1646285 based on the following engineering criteria:

Product Status Alignment: The 1082578 is classified as active product status, ensuring continued availability and manufacturer support, whereas the 1646285 is obsolete and subject to supply discontinuation.

Compliance Certification: Both parts maintain RoHS compliance. The 1082578 achieves ROHS3 compliance, representing current regulatory alignment. The 1082578 additionally carries REACH Unaffected status, providing enhanced environmental documentation.

Mechanical Compatibility: Identical M25 thread size and B10 form factor ensure direct mechanical fit in existing mounting applications. Dimensional variance is minimal (1mm length difference, 5mm width difference, 0.5mm height difference), remaining within typical installation tolerances for box mount connectors.

Enhanced Environmental Protection: The 1082578 provides IP66/IP67 ingress protection compared to the IP65 rating of the 1646285, offering superior dust and water resistance without compromising thermal or mechanical specifications.

Dual Entry Configuration: The 1082578 features dual side entry capability, providing expanded connectivity options while maintaining backward compatibility with single-entry applications through selective port utilization.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1082578 directly replace the 1646285 in existing installations?

A: Yes. Both connectors share identical M25 thread size, B10 form factor, and base box mount configuration. Dimensional differences are minimal and fall within standard installation tolerances. The 1082578 maintains the same operating temperature range (-40°C to 125°C) and housing material specifications.

Q: What is the primary difference between these two connectors?

A: The 1082578 provides enhanced ingress protection (IP66/IP67 versus IP65) and features dual side entry capability compared to the single side entry design of the 1646285. Both maintain identical core mechanical and thermal specifications.

Q: Why is the 1646285 listed as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The 1082578 represents the current active product offering from Phoenix Contact for this connector category and specifications.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The 1082578 achieves ROHS3 compliance and carries REACH Unaffected status, representing current regulatory standards. The 1646285 meets RoHS compliance requirements but does not specify ROHS3 or REACH status.

Q: What does the dual side entry configuration on the 1082578 mean for compatibility?

A: Dual side entry provides two connection points on the connector base. In applications requiring only single entry, one port remains unused without affecting functionality. This feature expands application flexibility while maintaining full backward compatibility.

Q: Are the packaging specifications different between these parts?

A: The 1646285 is listed with unspecified packaging, while the 1082578 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
