Phoenix Contact 1604729 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604729 is a base-mounted side entry heavy duty connector from the HEAVYCON® B series, designed for M20 thread applications with B6 size configuration. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is currently obsolete, making identification of suitable substitutes essential for ongoing maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604729 is determined by the following critical parameters that must remain consistent:

• Connector Type & Mounting: Base - Box Mount configuration
• Entry Style: Side Entry orientation
• Size Designation: B6 form factor
• Thread Interface: M20 thread size
• Housing Material: Aluminum, Die Cast construction
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part 1604729 maintains all core mechanical and electrical compatibility parameters. Enhanced ingress protection (IP66/IP67/IP69K versus IP65) and additional features (salt water resistance) represent functional improvements without compromising backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412825 serves as the direct substitute for the obsolete 1604729. Both parts maintain identical mechanical interfaces (M20 thread, B6 size, side entry configuration) and thermal operating range (-40°C to 125°C). The substitute is manufactured by the same OEM and carries equivalent ROHS3 compliance and REACH unaffected status.

The 1412825 represents an evolution within the HEAVYCON® product line, offering enhanced ingress protection ratings (IP66/IP67/IP69K) compared to the original IP65 specification. This upgrade provides superior environmental sealing without requiring design modifications to existing mounting interfaces. The minimal dimensional increase (2.15" versus 2.047" height) is negligible for most applications.

Selection of the 1412825 is appropriate for direct replacement in active designs and new installations requiring equivalent M20 B6 side entry base mount connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1412825 directly replace the 1604729 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (M20 thread, B6 size, side entry base mount). The 1412825 maintains the same operating temperature range and housing material. The height difference (2.15" versus 2.047") is minimal and does not affect standard mounting applications.

Q: What is the primary reason for substitution?

A: The 1604729 is obsolete. The 1412825 is an active product from Phoenix Contact's current HEAVYCON® EVO series, ensuring ongoing availability and supply chain continuity.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.

Q: Does the improved ingress protection (IP66/IP67/IP69K) affect compatibility?

A: No. Enhanced ingress protection represents a functional improvement. The 1412825 maintains all mechanical and electrical compatibility parameters required for direct substitution.

Q: What packaging is available for the 1412825?

A: The 1412825 is supplied in bulk packaging, differing from the original part's packaging specification.
