Phoenix Contact 1604937 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604937 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M25 thread size in the HEAVYCON® HV series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing system maintenance and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604937 is determined by the following critical parameters that must remain consistent:

• Connector Type & Style: Base - Box Mount, Side Entry configuration
• Thread Size: M25 (mechanical interface requirement)
• Operating Temperature Range: -40°C to 125°C (environmental specification)
• Housing Material: Aluminum, Die Cast (structural and thermal properties)
• Lock Location: Locking Clip (1) on Base Bottom (mechanical compatibility)

The substitute part 1412881 maintains these core parameters while operating in the HEAVYCON® EVO series. The primary differences are the connector size designation (B24 versus HV10/16) and enhanced ingress protection rating (IP66/IP67/IP69K versus IP65), which represent functional improvements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412881 serves as the direct substitute for the obsolete 1604937 based on the following engineering criteria:

Mechanical Compatibility: Both connectors maintain identical M25 thread size, side entry configuration, and locking clip placement on the base bottom, ensuring direct mechanical interchangeability in box mount applications.

Environmental Performance: The 1412881 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the original IP65 rating, offering superior dust and water resistance without compromising the original operating temperature specification (-40°C to 125°C).

Regulatory Compliance: The 1412881 meets ROHS3 compliance and REACH unaffected status, representing current regulatory standards. The original part maintains RoHS compliance but is classified as obsolete.

Series Evolution: The transition from HEAVYCON® HV to HEAVYCON® EVO represents a product line modernization by Phoenix Contact, with the 1412881 incorporating improved design features including salt water resistance and feed-through capability.

Dimensional Consistency: Height difference of 1mm (68mm versus 67mm) falls within acceptable mechanical tolerance for box mount applications and does not affect interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1412881 directly replace the 1604937 in existing installations?

A: Yes. Both connectors share identical M25 thread size, side entry configuration, and locking clip placement. The 1mm height difference does not affect mechanical compatibility in standard box mount applications.

Q: What is the significance of the size designation change from HV10/16 to B24?

A: The size designation reflects the product line evolution from HEAVYCON® HV to HEAVYCON® EVO series. The B24 designation in the EVO series corresponds to the same contact capacity and mating interface as the HV10/16, maintaining functional equivalence.

Q: Does the enhanced IP rating of the 1412881 affect compatibility?

A: No. Enhanced ingress protection (IP66/IP67/IP69K versus IP65) represents an improvement that does not compromise backward compatibility. Systems designed for IP65 operation will function correctly with the higher-rated substitute.

Q: Are there any packaging differences between these parts?

A: The 1604937 is supplied in standard packaging, while the 1412881 is supplied in bulk packaging. This affects logistics and inventory management but does not impact technical compatibility.

Q: What compliance certifications should be verified for new designs?

A: The 1412881 meets ROHS3 compliance and is REACH unaffected, representing current regulatory requirements. For applications requiring specific certifications, verify ECCN classification (EAR99 for 1412881) against project requirements.

Q: Is the operating temperature range identical between both parts?

A: Yes. Both connectors operate across -40°C to 125°C, ensuring thermal compatibility in all specified environmental conditions.
