Phoenix Contact 1771406 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1771406 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG16 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 ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771406 is determined by strict alignment with the following core parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B10 size class
• Thread Interface: Must accommodate PG16 thread size
• Locking Mechanism: Must feature Locking Clip (2) on Hood
• Operating Temperature: Must support -40°C to 125°C range
• Housing Material & Construction: Must be Aluminum, Die Cast
• RoHS Compliance: Must maintain RoHS Compliant status

The substitute part 1412832 meets all core substitution criteria while offering enhanced ingress protection specifications and additional environmental resistance features within the same mechanical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412832 is the direct substitute for the obsolete 1771406. Both components share identical mechanical mounting interfaces, thread specifications, and thermal operating ranges. The 1412832 maintains full RoHS compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

The 1412832 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance features, representing a performance upgrade within the same form factor. The dimensional variance (54.00mm versus 52.00mm height) is within acceptable tolerance for standard box mount applications and does not compromise mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1412832 directly replace the 1771406 in existing installations?

A: Yes. Both components maintain identical connector type, size designation (B10), thread interface (PG16), and locking mechanism specifications. The 1412832 is mechanically and electrically compatible as a direct substitute.

Q: What is the significance of the higher IP rating on the 1412832?

A: The 1412832 provides IP66/IP67/IP69K protection compared to the 1771406's IP65 rating. This represents enhanced dust and water ingress protection, including waterproof capability and salt water resistance. This upgrade does not create incompatibility; it extends environmental performance capability.

Q: Are there dimensional concerns with the 1412832 substitution?

A: The 1412832 height dimension is 54.00mm compared to 52.00mm for the 1771406. This 2.00mm difference is within standard mechanical tolerance for box mount connector applications and does not affect mounting compatibility or electrical performance.

Q: Why is the 1771406 listed as obsolete?

A: The 1771406 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412832). Phoenix Contact has transitioned production to the newer series while maintaining backward compatibility through equivalent substitute parts.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1771406 and 1412832 maintain full RoHS compliance status, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the packaging difference between these parts?

A: The 1771406 is supplied in standard packaging, while the 1412832 is supplied in bulk packaging. This does not affect component functionality or compatibility.
