Phoenix Contact 1604788 Heavy Duty Connector Base - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 1604788 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M25 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new installations where the original series is no longer available.

Engineering Selection Recommendations
The Phoenix Contact 1412855 is a direct functional substitute for the 1604788. Both connectors share identical mechanical interfaces (B16 size, M25 thread, side entry configuration) and maintain the same operating temperature range. The 1412855 is currently in active production status, ensuring long-term availability and supply chain continuity.
The 1412855 provides enhanced environmental protection with IP66/IP67/IP69K ingress rating compared to the IP65 rating of the original 1604788. This upgrade includes salt water resistance and feed-through capability, making it suitable for applications requiring higher environmental durability. Both parts maintain RoHS compliance and are constructed from die-cast aluminum.
Selection between these parts should be based on application requirements: the 1604788 remains suitable for existing installations where IP65 protection is sufficient, while the 1412855 is recommended for new designs or replacements in environments requiring enhanced moisture or corrosive element protection.
Frequently Asked Questions (FAQ)
Q: Can the 1412855 directly replace the 1604788 in existing installations?
A: Yes. Both connectors share identical mechanical mounting interfaces (M25 thread, B16 size, side entry configuration) and locking mechanisms. The 1412855 provides equivalent or superior performance across all critical parameters.
Q: What is the primary difference between these two connectors?
A: The 1412855 offers enhanced ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance and feed-through features. Both maintain identical operating temperature ranges and housing materials.
Q: Why is the 1604788 listed as obsolete?
A: The 1604788 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412855). Phoenix Contact has transitioned production to the newer EVO line.
Q: Are there packaging differences between these parts?
A: The 1604788 is available in standard packaging, while the 1412855 is supplied in bulk packaging. This does not affect connector functionality or compatibility.
Q: Do both connectors meet the same regulatory standards?
A: Yes. Both the 1604788 and 1412855 are RoHS Compliant and carry the same ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
Q: What is the Moisture Sensitivity Level (MSL) for these connectors?
A: Both connectors have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
