Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903792 qualifies as a direct substitute based on the following critical parameters:

• Identical Positions / Poles: Both parts feature 34-position configurations, ensuring mechanical and electrical compatibility with existing connector interfaces.
• Matching Connection Types: Both employ spring connection on the process side and rectangular male connectors on the control side, maintaining interface compatibility.
• Compatible Voltage Rating: The 2903792 is rated for 60VAC/DC, which encompasses the 60VDC specification of the original part.
• Equivalent Current Rating: Both parts maintain 1 A per contact, preserving electrical load capacity.
• Matching Operating Temperature Range: Both operate across -20°C ~ 50°C, ensuring thermal compatibility.
• RoHS Compliance: Both parts meet RoHS requirements, supporting regulatory compliance continuity.

The primary difference lies in wire gauge specification: the 2903792 accepts 14-26 AWG wire, compared to the 2302939's 12-24 AWG range. This represents an expanded wire gauge capability that accommodates the original specification while extending compatibility to larger gauge conductors.
