Phoenix Contact 1604787 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604787 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M25 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1604787 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: Must be B16 to ensure mechanical and electrical compatibility
• Thread Size: Must be M25 for proper installation interface
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• Housing Material: Aluminum, Die Cast construction
• Ingress Protection: Must meet or exceed IP65 rating

The substitute part 1412865 maintains all core mechanical and electrical parameters while offering enhanced environmental protection (IP66/IP67/IP69K) and improved material specifications through the HEAVYCON® EVO series evolution.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412865 is a direct substitute for the obsolete 1604787 based on identical mechanical form factor, electrical interface, and core operational parameters. The substitute maintains full compatibility across all critical dimensions (M25 thread, B16 size, side entry configuration) and operating conditions (-40°C ~ 125°C).

The 1412865 represents an evolution within the Phoenix Contact product line, transitioning from the HEAVYCON® B series to the HEAVYCON® EVO series. This upgrade provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and salt water resistance, while maintaining backward compatibility with existing installations. Both parts carry equivalent regulatory compliance (RoHS, EAR99, HTSUS classification) and unlimited moisture sensitivity ratings.

Selection of the 1412865 is supported by its active product status and current availability, eliminating supply chain risk associated with obsolete component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the 1412865 directly replace the 1604787 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (M25 thread, B16 size, side entry configuration), locking mechanisms, and operating temperature ranges. The dimensional variance (1.5mm length, 1mm height) falls within standard installation tolerances for box mount applications.

Q: What is the difference in ingress protection between these parts?

A: The original 1604787 provides IP65 protection (dust tight, water resistant). The substitute 1412865 provides IP66/IP67/IP69K protection, offering enhanced dust tightness, water resistance, and waterproof capability. This represents an improvement in environmental sealing without affecting mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The 1604787 was supplied with standard packaging. The 1412865 is supplied in bulk packaging. Both maintain identical MSL ratings (1 - Unlimited) and handling requirements.

Q: Do both parts meet current regulatory requirements?

A: The 1604787 carries RoHS Compliant certification. The 1412865 carries ROHS3 Compliant certification, representing current regulatory alignment. Both share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: Why is the 1604787 listed as obsolete?

A: The 1604787 has been superseded by the 1412865 within the Phoenix Contact product portfolio. The HEAVYCON® EVO series (1412865) represents the current generation offering improved environmental protection and compliance specifications.
