Phoenix Contact 1772159 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1772159 is a heavy duty connector hood designed for top entry applications with PG29 thread size in the HEAVYCON® B series. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1772159 is determined by strict alignment across the following critical parameters:

• Connector Type & Style: Must be hood connector with top entry configuration
• Size Designation: Must be B48 to ensure mechanical compatibility with existing base assemblies
• Thread Size: Must be PG29 for panel mounting compatibility
• Series Compatibility: HEAVYCON® B series maintains consistent interface specifications
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material: Aluminum die cast construction for thermal and mechanical properties
• Ingress Protection: Must meet or exceed IP65 rating

The Phoenix Contact 1424851 qualifies as a substitute based on these parameters. While it provides enhanced IP66/IP67 protection and includes salt water resistance features, it maintains identical mechanical interfaces (B48 size, PG29 thread, top entry style) and operates within the same temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424851 is the qualified substitute for the obsolete 1772159. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical B48 size designation, PG29 thread specification, and top entry configuration, ensuring direct mechanical interchangeability within existing assemblies.

Environmental Protection Enhancement: The 1424851 provides IP66/IP67 protection versus the original IP65 rating, offering improved dust and water ingress protection. This represents a performance upgrade suitable for applications requiring enhanced environmental sealing.

Compliance Status: The 1424851 carries active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. The original part's obsolete status necessitates transition to this active alternative.

Thermal Performance: Both parts operate across the identical -40°C to 125°C temperature range, maintaining thermal compatibility for existing system designs.

Material Consistency: Aluminum die cast housing in both parts ensures equivalent thermal conductivity and mechanical rigidity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1424851 directly replace the 1772159 in existing installations?

A: Yes. Both parts maintain identical mechanical interfaces (B48 size, PG29 thread, top entry style, locking clip configuration) and operate within the same temperature range. Direct substitution is mechanically and thermally compatible.

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

A: The 1424851 provides enhanced ingress protection (IP66/IP67 versus IP65) and includes salt water resistance. Both parts are functionally equivalent for standard heavy duty connector hood applications, with the 1424851 offering superior environmental sealing.

Q: Why is the 1772159 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1424851 represents the current active equivalent within the HEAVYCON® B series, ensuring continued availability and support.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist. The 1772159 measures 5.177" L x 4.604" W x 3.780" H, while the 1424851 measures 5.197" L x 4.643" W x 4.232" H. These differences do not affect mechanical interface compatibility but should be verified for space-constrained installations.

Q: What compliance certifications apply to the substitute part?

A: The 1424851 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution and use.

Q: Is the enhanced IP66/IP67 rating of the 1424851 suitable for all applications originally designed for IP65?

A: Yes. Enhanced ingress protection ratings are backward compatible with applications specified for lower ratings. The 1424851 provides equal or superior environmental protection for any application originally designed for the 1772159.
