Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1771671 is determined by strict alignment across the following critical parameters:

• Connector type classification (Base - Box Mount)
• Entry style (Side Entry)
• Connector size designation (B16)
• Thread entry specification (PG21)
• Operating temperature range (-40°C to 125°C)
• Housing material composition (Aluminum, Die Cast)
• RoHS compliance status

The substitute part 1412853 maintains compatibility across all these core parameters while offering enhanced ingress protection and additional environmental resistance features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412853 serves as the direct functional equivalent for the obsolete 1771671. Both components share identical mechanical and electrical specifications across connector type, size, thread entry, and operating temperature parameters. The 1412853 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

The 1412853 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance as an additional feature. These improvements do not compromise compatibility with existing mechanical interfaces or electrical requirements. Both components are RoHS compliant and utilize identical housing materials and construction methods.

Frequently Asked Questions (FAQ)

Q: Can the 1412853 directly replace the 1771671 in existing installations?

A: Yes. Both components share identical specifications for connector type (Base - Box Mount), entry style (Side Entry), size (B16), thread entry (PG21), operating temperature range (-40°C to 125°C), and housing material (Aluminum, Die Cast). Mechanical mounting and electrical interface compatibility are maintained.

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

A: The 1412853 offers enhanced ingress protection (IP66/IP67/IP69K) compared to the 1771671 (IP65) and includes salt water resistance. The 1412853 belongs to the HEAVYCON® EVO series while the 1771671 is from the HEAVYCON® B series. The 1412853 maintains active product status.
