Phoenix Contact 1772256 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1772256 is a heavy duty connector hood designed for 90° side entry applications with PG11 thread size in the HEAVYCON® D series. This component provides IP54 ingress protection (dust protected, water resistant) and operates across -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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1772256 is determined by the following critical parameters:

• Connector Type & Style: Must be Hood - 90° with Side Entry configuration to maintain mechanical compatibility with existing mating interfaces
• Size Designation: D7 size is mandatory for electrical and mechanical alignment
• Lock Mechanism: Locking Clip (1) on Base Bottom must be preserved for secure assembly
• Housing Material: Polyamide (PA) Nylon construction ensures chemical and thermal compatibility
• Operating Temperature Range: -40°C ~ 125°C operational envelope must be maintained or exceeded
• Series Compatibility: HEAVYCON® D series maintains design consistency

The substitute part 1419257 maintains all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66 vs. IP54) and improved product status (Active vs. Obsolete). The thread size differs (M20 vs. PG11), which represents a mechanical interface change requiring system-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The 1419257 serves as the active production equivalent for the obsolete 1772256. Both components share identical mechanical form factors (D7 size, 90° side entry hood configuration) and thermal operating ranges. The primary differences are:

Thread Size Interface: The 1772256 uses PG11 threading while the 1419257 uses M20 threading. This represents a mechanical interface change that requires verification of mounting hardware and enclosure provisions in the target application.

Ingress Protection Enhancement: The 1419257 provides IP66 rating (dust tight, water resistant) compared to the 1772256's IP54 rating (dust protected, water resistant). This represents an improvement in environmental sealing capability.

Compliance Status: The 1419257 carries ROHS3 Compliant certification and REACH Unaffected status, ensuring alignment with current regulatory requirements. The 1772256 meets RoHS Compliance standards.

Product Availability: The 1419257 is in active production status with 1121 units in stock, while the 1772256 is obsolete with limited remaining inventory (678 units).

Frequently Asked Questions (FAQ)

Q: Can the 1419257 directly replace the 1772256 in existing installations?

A: Direct mechanical replacement requires verification of the thread interface. The 1772256 uses PG11 threading while the 1419257 uses M20 threading. Enclosure mounting provisions and cable gland compatibility must be confirmed before substitution.

Q: What is the significance of the IP66 rating on the 1419257 compared to IP54 on the 1772256?

A: IP66 provides dust-tight protection and enhanced water resistance compared to IP54's dust-protected, water-resistant specification. The 1419257 offers superior environmental sealing for applications requiring higher ingress protection.

Q: Are both parts compatible with the same D7 connector interfaces?

A: Yes. Both the 1772256 and 1419257 maintain D7 size designation and 90° side entry hood configuration, ensuring electrical and mechanical compatibility with D7 mating connectors within the HEAVYCON® D series.

Q: What are the packaging differences between these parts?

A: The 1772256 is supplied in standard packaging, while the 1419257 is supplied in bulk packaging. Bulk packaging may affect procurement quantities and handling procedures.

Q: Are there thermal operating range differences between the two parts?

A: No. Both components operate across the identical -40°C to 125°C temperature range, ensuring thermal compatibility in equivalent applications.

Q: Which part should be specified for new designs?

A: The 1419257 should be specified for new designs due to its active product status, enhanced IP66 ingress protection, and current regulatory compliance (ROHS3, REACH Unaffected). The 1772256 is obsolete and should only be used for legacy system maintenance where thread interface compatibility is confirmed.
