Phoenix Contact 1771370 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1771370 is a heavy duty connector base designed for box mount, side entry applications with PG16 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 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 1771370 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B10 to ensure mechanical and electrical compatibility
• Thread Size: Must be PG16 for proper mounting interface
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material: Aluminum die cast construction maintains thermal and mechanical properties
• Lock Mechanism: Locking Clip (2) on Base Bottom configuration must be preserved

The substitute part 1412837 meets all these core substitution criteria while offering enhanced ingress protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412837 serves as a direct substitute for the obsolete 1771370 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical connector type, style, size designation (B10), thread size (PG16), and locking mechanism configuration, ensuring direct mechanical interchangeability in box mount applications.

Thermal Performance: Both components operate across the identical temperature range of -40°C to 125°C, maintaining thermal performance requirements for the application.

Environmental Protection: The 1412837 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1771370 (IP65), offering superior dust and water resistance without compromising the original design intent.

Regulatory Compliance: The 1412837 meets ROHS3 compliance and REACH unaffected status, representing current regulatory standards. The 1771370 meets RoHS compliance requirements.

Product Availability: The 1412837 maintains active product status with current manufacturing support, whereas the 1771370 is obsolete. This ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1412837 directly replace the 1771370 in existing installations?

A: Yes. Both parts share identical mechanical interfaces (B10 size, PG16 thread, side entry configuration, locking clip placement) and thermal operating ranges (-40°C to 125°C). The 1412837 is mechanically and electrically compatible for direct substitution.

Q: What is the difference in ingress protection between these parts?

A: The 1771370 provides IP65 protection (dust tight, water resistant). The 1412837 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The enhanced rating in the substitute part does not reduce compatibility; it extends environmental protection capability.

Q: Are there dimensional differences between the two parts?

A: The height dimension differs slightly: 1771370 measures 2.047" H (52.00mm), while 1412837 measures 2.126" H (54.00mm). Length and width dimensions remain identical at 3.661" L x 2.047" W (93.00mm x 52.00mm). Verify mounting clearance in your specific application.

Q: What packaging is available for the 1412837?

A: The 1412837 is supplied in bulk packaging, whereas the 1771370 packaging specification was not provided. Confirm packaging requirements with your procurement process.

Q: Does the 1412837 include salt water resistance?

A: Yes. The 1412837 includes salt water resistant features, providing additional environmental protection compared to the 1771370 specification.

Q: Are both parts RoHS compliant?

A: Yes. The 1771370 is RoHS compliant. The 1412837 meets the more current ROHS3 compliance standard, ensuring alignment with current regulatory requirements.
