Phoenix Contact 1604725 Heavy Duty Connector Base - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 1604725 is a heavy duty connector base designed for box mount, side entry applications with M25 thread size in the HEAVYCON® B series. This component provides IP65 ingress protection (dust tight, water resistant) and operates across a wide temperature range of -40°C to 125°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation
Substitution of the Phoenix Contact 1604725 is determined by the following critical parameters that must remain consistent:
- Connector Type & Style: Base - Box Mount, Side Entry configuration
- Size Designation: B6 form factor
- Thread Size: M25 mechanical interface
- Series Compatibility: HEAVYCON® B series
- Housing Material: Aluminum die cast construction
- Operating Temperature: -40°C to 125°C range
- RoHS Compliance: Regulatory requirement maintenance
The substitute part 1082556 maintains these core parameters while introducing enhanced ingress protection (IP66/IP67 versus IP65) and additional features such as dual entry capability and salt water resistance. The mechanical mounting dimensions remain compatible within acceptable tolerances for box mount applications.

Engineering Selection Recommendations
The Phoenix Contact 1082556 serves as the direct functional substitute for the obsolete 1604725. Both components share identical core mechanical and electrical specifications within the HEAVYCON® B series, maintaining compatibility with existing M25 threaded installations and B6 form factor requirements.
The 1082556 offers enhanced environmental protection through IP66/IP67 rating compared to the IP65 specification of the original part. This upgrade provides superior dust and water ingress protection without compromising mechanical compatibility. The dual entry capability of the substitute does not preclude single-entry applications; the additional entry point remains unused in such configurations.
Regulatory compliance is maintained through ROHS3 certification on the substitute part, exceeding the RoHS compliance requirement of the original component. Both parts operate identically across the -40°C to 125°C temperature range and utilize identical aluminum die cast housing construction.
The 1082556 is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete 1604725.
Frequently Asked Questions (FAQ)
Q: Can the 1082556 directly replace the 1604725 in existing installations?
A: Yes. Both components share identical M25 thread size, B6 form factor, and HEAVYCON® B series designation. The mechanical mounting interface and locking clip configuration are identical. The dual entry feature of the 1082556 does not affect single-entry applications.
Q: What is the difference in ingress protection between these parts?
A: The 1604725 provides IP65 protection (dust tight, water resistant). The 1082556 provides IP66/IP67 protection (dust tight, water resistant, and waterproof). IP66/IP67 represents enhanced environmental sealing suitable for more demanding moisture exposure conditions.
Q: Are there dimensional differences between these parts?
A: Minor dimensional variations exist. The 1604725 measures 3.307" L x 2.244" W x 2.913" H. The 1082556 measures 3.307" L x 2.047" W x 2.945" H. The length remains identical; width and height variations are within acceptable tolerances for box mount applications and do not affect mechanical compatibility.
Q: Does the dual entry configuration of the 1082556 create compatibility issues?
A: No. The dual entry design of the 1082556 accommodates two M25 connections simultaneously. In applications requiring single entry, one entry point remains unused without affecting performance or mechanical integrity.
Q: What is the regulatory compliance status of the substitute part?
A: The 1082556 meets ROHS3 compliance, which exceeds the RoHS compliance requirement of the original 1604725. Both parts maintain EAR99 export classification and identical HTSUS coding.
Q: Is the 1082556 available in the same packaging as the 1604725?
A: The 1604725 was supplied in standard packaging. The 1082556 is supplied in bulk packaging. Consult with your supplier regarding packaging options and minimum order quantities for your specific application requirements.
