Phoenix Contact 1604931 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604931 is a heavy-duty hood connector with top entry configuration, M25 thread size, and HV3 contact arrangement. Designed for industrial applications requiring IP65 ingress protection (dust tight, water resistant), this connector operates across -40°C to 125°C and features aluminum die-cast housing with powder coating. The part is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604931 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Connector Type: Hood configuration
• Style: Top Entry mounting
• Thread Size: M25 (mechanical interface requirement)
• Lock Location: Locking Clip (2) on Base Bottom
• Housing Material: Aluminum, Die Cast
• Operating Temperature Range: -40°C to 125°C minimum
• Manufacturer: Phoenix Contact (series continuity)

Functional Equivalence Parameters:

• Ingress Protection: IP65 or higher rating
• RoHS Compliance: Required for current procurement standards

The substitute part 1412621 maintains all mandatory compatibility parameters while providing enhanced ingress protection (IP66/IP67/IP69K) and active product status. Both connectors share identical thread sizing, locking mechanism, material composition, and temperature operating range, establishing direct functional equivalence for replacement applications.

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1412621

The 1412621 is the direct functional equivalent for the obsolete 1604931. Selection is based on:

• Mechanical Compatibility: Identical M25 thread size, locking mechanism, and mounting interface ensure drop-in replacement capability
• Environmental Performance: Enhanced ingress protection rating (IP66/IP67/IP69K) exceeds the original IP65 specification, providing superior protection in demanding industrial environments
• Compliance Status: ROHS3 compliance meets current regulatory requirements; REACH Unaffected status confirms material compliance
• Product Availability: Active product status ensures continued supply and technical support from Phoenix Contact
• Thermal Performance: Identical -40°C to 125°C operating range maintains thermal compatibility with existing system designs
• Material Consistency: Aluminum die-cast housing with identical material composition preserves mechanical and thermal characteristics

The dimensional increase in height (45mm to 57mm) and width (43mm to 44mm) must be evaluated against available mounting space in the target application. The enhanced ingress protection and active product status make this substitute the preferred choice for new installations and system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the 1412621 directly replace the 1604931 in existing installations?

A: Yes, the 1412621 provides direct mechanical and functional replacement. The M25 thread size, locking clip configuration, and mounting interface are identical. Verify available mounting space accommodates the slightly larger dimensions (57mm height vs. 45mm, 44mm width vs. 43mm).

Q: What is the difference between IP65 and IP66/IP67/IP69K ratings?

A: The 1604931 provides IP65 protection (dust tight, water resistant). The 1412621 provides IP66/IP67/IP69K protection, which includes dust tight, water resistant, and waterproof capabilities with enhanced resistance to high-pressure water jets. The substitute offers superior environmental protection.

Q: Why is the 1604931 listed as obsolete?

A: Obsolete status indicates Phoenix Contact has discontinued this model. The 1412621 represents the current-generation equivalent within the HEAVYCON® product family, offering improved specifications and compliance with modern regulatory standards.

Q: Are there any compatibility concerns with the different size designations (HV3 vs. B10)?

A: The size designations reflect different contact arrangements within their respective series (HEAVYCON® HV vs. HEAVYCON® B). Both maintain M25 thread compatibility and identical locking mechanisms. Verify contact pin configuration matches your application requirements.

Q: What is the significance of ROHS3 compliance on the 1412621?

A: ROHS3 represents the current iteration of Restriction of Hazardous Substances compliance, reflecting updated regulatory requirements. This ensures the substitute meets modern environmental and material safety standards required for industrial procurement.

Q: Does the substitute part require any design modifications?

A: No design modifications are required for mechanical installation. The identical M25 thread, locking mechanism, and mounting interface ensure compatibility. Evaluate mounting space for the dimensional differences and confirm contact pin configuration matches your electrical requirements.
