Phoenix Contact 1773734 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1773734 is a heavy duty connector hood designed for top 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 part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1773734 is determined by the following critical parameters that must remain consistent or be upgraded:

• Connector Type & Style: Hood connector with top entry configuration
• Thread Size: PG21 mechanical interface
• Ingress Protection: Minimum IP65 rating (dust tight, water resistant); higher ratings (IP66/IP67/IP69K) are acceptable upgrades
• Operating Temperature: -40°C to 125°C range
• Housing Material: Aluminum die cast construction
• RoHS Compliance: Required for regulatory alignment

The substitute part 1412724 maintains all critical mechanical and environmental parameters while providing enhanced ingress protection (IP66/IP67/IP69K) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412724 is the direct substitute for the obsolete 1773734. Both components share identical mechanical interfaces (PG21 thread size, top entry hood configuration) and thermal operating ranges (-40°C to 125°C). The 1412724 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65), making it suitable for applications requiring greater environmental sealing. Both parts maintain RoHS compliance and aluminum die cast housing construction. The 1412724 carries active product status with current manufacturing support, eliminating supply chain risk associated with the obsolete 1773734.

Frequently Asked Questions (FAQ)

Q: Can the 1412724 directly replace the 1773734 in existing installations?

A: Yes. Both connectors share identical PG21 thread size, top entry hood configuration, and operating temperature range (-40°C to 125°C). The 1412724 provides equal or superior environmental protection (IP66/IP67/IP69K versus IP65).

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

A: IP65 provides dust tight and water resistant protection. IP66/IP67/IP69K extends protection to include waterproof operation under immersion and high-pressure jet conditions. The 1412724's enhanced rating is compatible with applications originally specified for IP65.

Q: Are there packaging differences between these parts?

A: The 1773734 is supplied in standard packaging, while the 1412724 is supplied in bulk packaging. This does not affect functional compatibility.

Q: Why is the 1773734 obsolete?

A: The 1773734 belongs to the HEAVYCON® HV series, which has been superseded by the HEAVYCON® B series (represented by 1412724). Phoenix Contact has transitioned product lines to the newer B series, which offers enhanced environmental protection and active manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1773734 and 1412724 are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.
