Phoenix Contact 1773705 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1773705 is a heavy duty connector hood designed for side entry applications with PG21 thread size, part of the HEAVYCON® HV series. This component 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 classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where similar performance characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1773705 is determined by the following critical parameters:

• Connector Type & Style: Must be hood connector with side entry configuration
• Thread Size: PG21 thread size for mechanical compatibility with existing mounting infrastructure
• Operating Temperature Range: Must support -40°C to 125°C operational envelope
• Housing Material: Aluminum die cast construction for structural and thermal properties
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Ingress Protection: IP65 minimum rating to maintain environmental sealing performance

The substitute part Phoenix Contact 1412728 meets all critical substitution criteria. While it belongs to the HEAVYCON® B series (versus the original HV series) and provides enhanced ingress protection (IP66/IP67/IP69K), it maintains mechanical compatibility through identical thread size (PG21), identical operating temperature range (-40°C to 125°C), and equivalent housing material specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412728 is the qualified substitute for the obsolete 1773705. Selection is supported by the following engineering factors:

Mechanical Compatibility: Both parts share identical PG21 thread sizing and locking clip configuration, ensuring direct mechanical interchange in existing mounting applications without modification.

Thermal Performance: Identical operating temperature range (-40°C to 125°C) maintains thermal design margins and system reliability across the full operational envelope.

Regulatory Compliance: Both parts maintain ROHS3 compliance and equivalent REACH/ECCN classifications, satisfying procurement and supply chain compliance requirements.

Environmental Protection Enhancement: The substitute part provides superior ingress protection (IP66/IP67/IP69K versus IP65), offering enhanced environmental sealing performance in demanding applications. This represents a performance upgrade rather than a compromise.

Active Product Status: The 1412728 is currently in active production with confirmed inventory availability (715 pcs), ensuring long-term supply chain continuity and support.

Frequently Asked Questions (FAQ)

Q: Can the 1412728 directly replace the 1773705 in existing installations?

A: Yes. Both parts share identical PG21 thread sizing, identical locking clip configuration, and identical operating temperature range. Mechanical and thermal compatibility is confirmed. The 1412728 provides enhanced ingress protection as an additional benefit.

Q: What is the difference between the HV and B series designations?

A: The series designation reflects product line evolution within Phoenix Contact's HEAVYCON® connector family. The 1412728 (B series) represents a current-generation design with enhanced environmental sealing capabilities (IP66/IP67/IP69K) compared to the original HV series (IP65). Both maintain equivalent mechanical interfaces and thermal specifications.

Q: Are there any dimensional differences between these parts?

A: Dimensional specifications are nearly identical. The 1773705 measures 3.701" L × 1.693" W × 2.362" H (94.00mm × 43.00mm × 60.00mm). The 1412728 measures 3.681" L × 1.732" W × 2.362" H (94.60mm × 44.00mm × 60.00mm). Height is identical; length and width variations are within typical manufacturing tolerances and do not affect mounting compatibility.

Q: Does the enhanced IP rating of the 1412728 affect compatibility?

A: No. Enhanced ingress protection (IP66/IP67/IP69K versus IP65) represents a performance upgrade. The substitute part meets or exceeds all environmental sealing requirements of the original specification.

Q: What is the inventory status for the substitute part?

A: The Phoenix Contact 1412728 is in active production with 715 pcs currently in stock as new original inventory, ensuring availability for immediate procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1773705 and 1412728 are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.
