Phoenix Contact 1773721 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1773721 is a heavy duty connector hood designed for side entry applications with PG21 thread size, part of the HEAVYCON® HV series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a wide temperature range of -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and system integration applications where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1773721 is determined by the following critical parameters that must align with the original specification:

• Connector Type & Style: Hood connector with side entry configuration
• Thread Size: PG21 thread for consistent mounting interface
• Operating Temperature Range: -40°C to 125°C capability
• Housing Material: Aluminum die cast construction
• RoHS Compliance: Required for regulatory alignment
• Ingress Protection: IP65 minimum rating for environmental sealing

The Phoenix Contact 1412720 qualifies as a substitute based on these parameters. While it belongs to the HEAVYCON® B series (versus the original HV series) and features an enhanced IP66/IP67/IP69K rating, it maintains compatibility across all critical substitution criteria: identical thread size (PG21), matching operating temperature range (-40°C to 125°C), equivalent housing material (aluminum die cast), RoHS compliance, and active product status.

Engineering Selection Recommendations

The Phoenix Contact 1412720 is the identified substitute for the obsolete 1773721. Selection of this substitute is supported by the following engineering factors:

• Product Status: The 1412720 maintains active product status, ensuring ongoing availability and supply chain continuity.
• Regulatory Compliance: Both components are RoHS compliant, maintaining alignment with environmental and regulatory requirements.
• Interface Compatibility: Identical PG21 thread size and locking clip configuration ensure mechanical compatibility with existing mounting interfaces.
• Environmental Performance: The 1412720 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the original IP65 rating, offering superior environmental sealing in demanding applications. The addition of salt water resistance in the substitute provides extended durability in corrosive environments.
• Thermal Performance: Matching operating temperature range (-40°C to 125°C) ensures equivalent thermal performance across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1412720 directly replace the 1773721 in existing installations?

A: Yes. Both connectors share identical thread size (PG21), operating temperature range (-40°C to 125°C), housing material (aluminum die cast), and locking mechanism configuration. The mechanical and electrical interfaces are compatible.

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

A: The 1412720 belongs to the HEAVYCON® B series and provides enhanced ingress protection (IP66/IP67/IP69K) compared to the original HV series IP65 rating. The substitute also includes salt water resistance, making it suitable for more demanding environmental conditions.

Q: Why is the 1773721 listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The 1412720 represents the current active equivalent within Phoenix Contact's heavy duty connector portfolio.

Q: Are there any dimensional differences between these connectors?

A: Minor dimensional variations exist. The 1773721 measures 3.701" L x 1.693" W x 2.559" H, while the 1412720 measures 3.681" L x 1.732" W x 2.362" H. These differences are within typical tolerance ranges for hood connector designs and do not affect mounting interface compatibility.

Q: What certifications apply to both connectors?

A: Both the 1773721 and 1412720 are RoHS compliant and carry the same ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
