Phoenix Contact 1604786 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604786 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 a temperature range of -40°C to 125°C. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new installations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604786 is determined by the following critical parameters that must remain consistent:

• Connector Type: Base - Box Mount
• Style: Side Entry
• Size: B16
• Thread Size: M25
• Operating Temperature Range: -40°C to 125°C
• Housing Material: Aluminum, Die Cast
• Lock Location: Locking Clip (1) on Base Bottom

The substitute part 1412865 maintains all these core parameters while offering enhanced ingress protection (IP66/IP67/IP69K versus IP65) and additional features including salt water resistance. Both parts are manufactured by Phoenix Contact and share identical mechanical mounting interfaces and electrical performance characteristics within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412865 serves as a direct substitute for the obsolete 1604786 based on maintained mechanical and electrical compatibility. Both connectors share identical form factors, mounting interfaces, and operational specifications within the -40°C to 125°C temperature range.

The 1412865 represents an active product with current manufacturing support and enhanced environmental protection ratings (IP66/IP67/IP69K compared to IP65). This upgrade provides superior dust and water ingress protection, including waterproof capability and salt water resistance. Both parts maintain RoHS compliance with the 1412865 meeting ROHS3 standards.

For applications requiring the original IP65 specification, the 1412865 exceeds these requirements and remains fully compatible. The dimensional variance (height difference of 1mm) falls within standard manufacturing tolerances and does not affect mounting or functional performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1412865 directly replace the 1604786 in existing installations?

A: Yes. Both connectors maintain identical connector type (base - box mount), style (side entry), size (B16), thread size (M25), and operating temperature range (-40°C to 125°C). Mechanical mounting interfaces and locking mechanisms are identical. The 1412865 provides enhanced ingress protection without compromising compatibility.

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

A: The 1412865 offers superior ingress protection (IP66/IP67/IP69K) compared to the 1604786 (IP65), includes salt water resistance, and features feed-through capability. Both maintain the same core mechanical and electrical specifications.

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

A: The 1604786 is supplied in standard packaging, while the 1412865 is supplied in bulk packaging. This does not affect connector performance or compatibility.

Q: Why is the 1604786 listed as obsolete?

A: The 1604786 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by 1412865). The newer series provides enhanced environmental protection and additional features while maintaining backward compatibility.

Q: Are both connectors RoHS compliant?

A: Yes. The 1604786 is RoHS Compliant, and the 1412865 is ROHS3 Compliant, meeting current regulatory requirements.
