Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412853 serves as the direct functional equivalent for the obsolete 1771668. Both components share identical mechanical and electrical specifications for connector type, size, thread configuration, and operating temperature range. The 1412853 maintains full RoHS compliance and is currently in active production status, ensuring supply chain continuity and long-term availability.

The 1412853 is manufactured in the HEAVYCON® EVO series and includes enhanced ingress protection ratings (IP66/IP67/IP69K) and salt water resistance features not specified in the original 1771668. These enhancements provide superior environmental protection while maintaining complete mechanical and electrical compatibility with existing installations and specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1412853 directly replace the 1771668 in existing installations?

A: Yes. Both components share identical connector type (Base - Box Mount), style (Side Entry), size (B16), thread size (PG21), and operating temperature specifications (-40°C to 125°C). The mechanical mounting interface and electrical characteristics are equivalent.

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

A: The 1412853 is the active production equivalent in the HEAVYCON® EVO series and includes specified ingress protection ratings (IP66/IP67/IP69K) and salt water resistance. The original 1771668 is obsolete and no longer manufactured.

Q: Are there any compatibility concerns with the dimensional differences noted?

A: The dimensional variations between the two parts (1771668: 117.00mm L x 57.00mm W x 67.00mm H versus 1412853: 117.50mm L x 57.00mm W x 68.00mm H) are within tolerance for box mount applications and do not affect functional compatibility or mounting interface specifications.

Q: Does the 1412853 maintain the same RoHS compliance status?

A: Yes. Both the 1771668 and 1412853 are RoHS compliant, ensuring regulatory compliance for applications requiring restricted substance adherence.

Q: What packaging options are available for the substitute part?

A: The 1412853 is available in bulk packaging, with 733 pieces currently in stock as new original inventory.
