Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646450 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B10 form factor
• Thread Size: Must be M25
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material: Must be Aluminum, Die Cast
• Ingress Protection: Must meet or exceed IP65 rating
• RoHS Compliance: Must maintain RoHS compliance status

The substitute part 1082582 meets all critical substitution criteria while providing enhanced ingress protection (IP66/IP67) and additional features including salt water resistance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082582 is the direct substitute for the obsolete 1646450. Both components share identical mechanical form factors, thread specifications, and thermal operating ranges. The 1082582 provides enhanced environmental protection through IP66/IP67 certification compared to the IP65 rating of the original part, making it suitable for applications requiring increased moisture and dust ingress resistance.

The 1082582 maintains current RoHS3 compliance status and is actively manufactured, ensuring long-term availability and supply chain continuity. The dual side entry configuration of the 1082582 provides additional flexibility for multi-connector applications while maintaining backward compatibility with M25 mounting interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 1082582 directly replace the 1646450 in existing installations?

A: Yes. Both connectors share identical M25 thread size, B10 form factor, aluminum die-cast housing, and identical external dimensions (93.00mm x 57.00mm x 74.00mm). The 1082582 provides equal or superior environmental protection and maintains the same operating temperature range.

Q: What is the difference between IP65 and IP66/IP67 ratings?

A: IP65 provides dust-tight and water-resistant protection against low-pressure water jets. IP66/IP67 extends protection to high-pressure water jets and temporary or sustained immersion in water. The 1082582 offers enhanced environmental sealing suitable for more demanding applications.

Q: Does the dual side entry configuration of the 1082582 affect mechanical compatibility?

A: No. The dual side entry feature is a functional enhancement that does not alter the external mounting dimensions or M25 thread interface. Mechanical compatibility with existing M25 mounting hardware is maintained.

Q: Are there packaging differences between the two parts?

A: The 1646450 is supplied in standard packaging, while the 1082582 is supplied in bulk packaging. This does not affect component functionality or electrical performance.

Q: What is the MSL rating for both connectors?

A: Both the 1646450 and 1082582 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity limitations for storage or handling.
