Phoenix Contact 1773996 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1773996 is a heavy duty connector hood designed for top 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 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 of the Phoenix Contact 1773996 is determined by the following critical parameters:

• Connector Type & Style: Hood configuration with top entry design
• Thread Size: PG21 mechanical interface requirement
• Operating Temperature Range: -40°C to 125°C capability
• Housing Material: Aluminum die cast construction
• Lock Mechanism: Locking clip (2) on hood
• Ingress Protection: Minimum IP65 rating or higher

The substitute part Phoenix Contact 1412771 meets these criteria while offering enhanced ingress protection (IP66/IP67/IP69K) and active product status. Both parts share identical thread sizing, temperature operating range, housing material composition, and mechanical locking configuration, establishing direct functional equivalence for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412771 serves as the direct substitute for the obsolete 1773996. Selection of the 1412771 is supported by:

• Product Status: The 1412771 maintains active product status, ensuring continued availability and supply chain reliability
• Regulatory Compliance: Both parts meet RoHS requirements; the 1412771 achieves ROHS3 compliance with REACH unaffected status
• Mechanical Compatibility: Identical PG21 thread sizing and locking clip configuration ensure direct mechanical interchange
• Environmental Protection: The 1412771 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the original IP65 rating, offering superior performance in demanding environments
• Thermal Performance: Matching -40°C to 125°C operating range maintains thermal design compatibility

Frequently Asked Questions (FAQ)

Q: Can the 1412771 directly replace the 1773996 in existing installations?

A: Yes. Both parts share identical PG21 thread sizing, mechanical locking configuration (2 locking clips on hood), housing material (aluminum die cast), and operating temperature range (-40°C to 125°C). The mechanical interface is fully compatible.

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

A: The 1412771 belongs to the HEAVYCON® B series and provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1773996 HEAVYCON® HV series (IP65). The 1412771 also maintains active product status versus the obsolete status of the 1773996.

Q: Are there any size differences between the two connectors?

A: Dimensional differences are minimal. The 1773996 measures 4.724" L x 1.693" W x 2.992" H, while the 1412771 measures 4.724" L x 1.732" W x 2.992" H. The width difference of 0.039" (1mm) is negligible for most mounting applications.

Q: Does the 1412771 include salt water resistance?

A: Yes. The 1412771 is specified with salt water resistant features, providing additional corrosion protection in marine or coastal environments compared to the standard 1773996.

Q: What packaging is available for the 1412771?

A: The 1412771 is supplied in bulk packaging, with 801 pieces currently in stock as new original inventory.
