Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771639 is determined by strict alignment with the following critical parameters:

• Connector Type: Base - Box Mount configuration
• Style: Side Entry orientation
• Size: B16 connector size
• Thread Size: PG21 thread specification
• Operating Temperature: -40°C to 125°C range
• Housing Material: Aluminum, Die Cast construction
• RoHS Compliance: Required

The Phoenix Contact 1412857 qualifies as a functional substitute based on matching all critical mechanical and electrical parameters. While the 1412857 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and additional salt water resistance features, the core connector interface, mounting configuration, and environmental operating specifications remain compatible with applications designed for the 1771639.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412857 is the direct functional equivalent for the obsolete 1771639. Both components maintain identical connector interface specifications, mounting configurations, and environmental operating parameters. The 1412857 represents an active product status with current manufacturing support and inventory availability.

The dimensional variance between the two parts (1.5mm length increase, 1mm height increase) falls within typical mechanical tolerance ranges for die-cast aluminum housings and does not impact connector interface compatibility. The enhanced ingress protection rating of the 1412857 (IP66/IP67/IP69K versus IP65) provides superior environmental sealing without compromising backward compatibility with existing connector mating interfaces.

Both components carry RoHS compliance certification and identical moisture sensitivity levels, ensuring regulatory and reliability equivalence for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1412857 directly replace the 1771639 in existing installations?

A: Yes. Both components share identical connector type, size, thread specification, and operating temperature range. The mechanical interface remains compatible. The minor dimensional differences do not affect mounting or mating connector alignment.

Q: What is the significance of the higher IP rating on the 1412857?

A: The 1412857 provides IP66/IP67/IP69K protection compared to the 1771639's IP65 rating. This represents enhanced dust and water ingress protection. Applications requiring only IP65 protection can use the 1412857 without performance degradation, as higher protection ratings are backward compatible with lower-rated specifications.

Q: Are there packaging differences between these parts?

A: The 1771639 packaging specification is not provided in the technical data. The 1412857 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Why is the 1771639 classified as obsolete?

A: The 1771639 belongs to the HEAVYCON® B series. The 1412857 represents the current HEAVYCON® EVO series evolution, which provides enhanced environmental protection and active manufacturing support.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components carry RoHS compliance certification and identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, ensuring equivalent regulatory status for export and procurement purposes.
