Phoenix Contact 1771972 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1771972 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771972 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B24 to ensure mechanical and electrical compatibility
• Thread Size: Must be PG21 for proper mounting interface
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material & Construction: Must be Aluminum, Die Cast for equivalent mechanical properties
• Lock Mechanism: Must feature Locking Clip (2) on Base Bottom

The identified substitute part (1412875) maintains all critical mechanical and electrical parameters while offering enhanced ingress protection specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412875 serves as a direct substitute for the obsolete 1771972 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical B24 size designation, PG21 thread interface, and locking clip configuration on the base bottom, ensuring drop-in compatibility in existing mounting applications.

Electrical & Environmental Performance: The 1412875 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the original IP65 specification, while maintaining the same -40°C to 125°C operating temperature range and aluminum die-cast housing construction.

Regulatory Compliance: The 1412875 meets ROHS3 compliance and REACH unaffected status, representing current regulatory standards. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Product Lifecycle Status: The 1412875 is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete 1771972.

Frequently Asked Questions (FAQ)

Q: Can the 1412875 be used as a direct replacement for the 1771972 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (B24 size, PG21 thread, side entry configuration, and locking clip placement), enabling direct substitution in box mount applications without modification to mounting hardware or connector mating interfaces.

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

A: The 1412875 belongs to the HEAVYCON® EVO series and provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1771972 (IP65). The 1412875 also includes salt water resistance features and represents the active product line, while the 1771972 is obsolete.

Q: Are there any dimensional differences between the 1771972 and 1412875?

A: The height dimension differs slightly: 1771972 measures 2.638" H (67.00mm), while 1412875 measures 2.677" H (68.00mm). This 0.039" (1.00mm) difference is negligible for standard box mount applications and does not affect mechanical compatibility.

Q: What packaging options are available for the 1412875?

A: The 1412875 is supplied in Bulk packaging, compared to the 1771972 which had no specified packaging designation.

Q: Are both parts RoHS compliant?

A: Yes. The 1771972 is RoHS Compliant, and the 1412875 is ROHS3 Compliant, both meeting current environmental and hazardous substance restrictions.
