Phoenix Contact 1604785 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604785 is a base-mount side entry heavy duty connector from the HEAVYCON® B series, designed for M25 thread applications with IP65 ingress protection. This connector features a box-mount configuration with a locking clip mechanism and operates across -40°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new installations requiring equivalent functionality.

Substitute Part Grouping Explanation

The Phoenix Contact 1412861 qualifies as a direct substitute for the 1604785 based on the following critical parameters:

• Connector Type & Style: Both are base-mount side entry configurations
• Size & Thread: Both use B16 size with M25 thread specification
• Lock Mechanism: Both feature identical locking clip (1) on base bottom
• Housing Material: Both utilize aluminum die-cast construction
• Operating Temperature: Both support -40°C ~ 125°C range
• RoHS Compliance: Both are RoHS compliant
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The 1412861 represents an evolution within the HEAVYCON® product family, offering enhanced ingress protection (IP66/IP67 versus IP65) and salt water resistance while maintaining mechanical and thermal compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412861 is the direct substitute for the obsolete 1604785. Both connectors maintain identical mechanical interfaces (M25 thread, B16 size, side entry configuration) and thermal specifications (-40°C ~ 125°C). The 1412861 is currently in active production status with higher inventory availability.

The 1412861 provides enhanced environmental protection (IP66/IP67 versus IP65) and salt water resistance, making it suitable for applications requiring superior ingress protection. Both parts carry RoHS compliance and identical export classifications (EAR99, HTSUS 8538.90.8180), ensuring regulatory compatibility.

Selection between these parts depends on environmental requirements: the 1412861 is recommended for applications requiring IP66/IP67 protection or salt water resistance, while the 1604785 specifications remain sufficient for standard IP65 dust and water resistance applications where the original part can still be sourced.

Frequently Asked Questions (FAQ)

Q: Can the 1412861 directly replace the 1604785 in existing installations?

A: Yes. Both connectors share identical mechanical specifications (M25 thread, B16 size, side entry, locking clip on base bottom) and thermal operating range (-40°C ~ 125°C). The 1412861 maintains full mechanical and electrical compatibility.

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

A: The 1412861 offers enhanced ingress protection (IP66/IP67 versus IP65) and includes salt water resistance. Both maintain the same housing material (aluminum die-cast), operating temperature range, and RoHS compliance.

Q: Why is the 1604785 listed as obsolete?

A: The 1604785 has been superseded by the 1412861 within the HEAVYCON® product family. The newer 1412861 (HEAVYCON® EVO series) provides improved environmental protection while maintaining backward compatibility.

Q: Are there packaging differences between these parts?

A: The 1604785 is listed with standard packaging, while the 1412861 is supplied in bulk packaging. Both are available as new original stock from Phoenix Contact.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the 1604785 and 1412861 are RoHS compliant, carry EAR99 export classification, and share the same HTSUS code (8538.90.8180). Both have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which connector should be selected for new designs?

A: The 1412861 is recommended for new designs due to its active production status, enhanced IP66/IP67 protection, and salt water resistance. It provides superior environmental protection while maintaining full compatibility with M25 thread and B16 size specifications.
