Phoenix Contact 1604723 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604723 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M20 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, repair, and new installations requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604723 is determined by the following critical parameters that must remain consistent:

• Connector Type & Style: Base - Box Mount, Side Entry configuration
• Size Designation: B6 connector size
• Thread Size: M20 mounting thread
• Operating Temperature: -40°C to 125°C range
• Housing Material: Aluminum, Die Cast construction
• Lock Mechanism: Locking Clip (1) on Base Bottom

The substitute part 1412821 maintains all these core parameters while offering enhanced ingress protection (IP66/IP67/IP69K versus IP65) and improved environmental resistance through salt water resistant features. Both parts share identical thread size, connector size, and operating temperature specifications, enabling direct functional substitution in applications where the enhanced protection rating is compatible with system requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412821 serves as the direct substitute for the obsolete 1604723 based on maintained core specifications: identical connector type, size, thread size, and operating temperature range. The 1412821 is currently in active production status with enhanced ROHS3 compliance and REACH unaffected certification, providing improved regulatory alignment for new designs and ongoing system support.

The primary technical advancement in the 1412821 is the enhanced ingress protection rating (IP66/IP67/IP69K versus IP65), which provides superior dust and water resistance including waterproof capability and salt water resistance. This upgrade is backward compatible for applications originally specified with IP65 protection, as the higher rating encompasses the original performance envelope.

Dimensional variations exist between the two parts (width and height differences of 12mm and 3.6mm respectively), requiring verification of mounting space availability in existing installations before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1412821 directly replace the 1604723 in existing installations?

A: The 1412821 maintains all critical functional parameters (connector type, size, thread size, operating temperature, and locking mechanism) required for direct substitution. However, dimensional differences in width (52mm versus 40mm) and height (54.6mm versus 52mm) must be verified against available mounting space before installation.

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

A: The 1412821 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1604723 (IP65), includes salt water resistant features, and represents the current generation HEAVYCON® EVO series versus the obsolete HEAVYCON® B series.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 1412821 meets ROHS3 standards and is REACH unaffected, providing enhanced regulatory compliance for current applications. The 1604723 meets RoHS compliance standards.

Q: What is the MSL rating for both parts?

A: Both the 1604723 and 1412821 carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations for storage and handling.

Q: Is the 1412821 available in the same packaging as the 1604723?

A: The 1412821 is supplied in bulk packaging. Original packaging specifications for the 1604723 were not provided in the technical data.
