Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2902956 is determined by the following critical parameters that must remain constant:

• Contact configuration: SPDT (1 Form C)
• Coil voltage: 120VAC/DC
• Contact current rating: 6 A
• Switching voltage capability: 250VAC, 250VDC maximum
• Mounting interface: DIN rail
• Termination method: Screw terminal
• Coil type: Non latching
• Contact material composition: Silver Tin Oxide (AgSnO)

The Phoenix Contact 2909525 meets all these substitution criteria and is classified as an active product, making it a direct equivalent for the obsolete 2902956.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909525 is the direct equivalent for the obsolete 2902956. Both parts are from the same PLC-RSC series and share identical electrical and mechanical specifications for all critical substitution parameters.

The 2909525 offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance provides enhanced environmental regulatory alignment
• Extended operating temperature range (-40°C to 60°C versus -20°C to 60°C) offers broader operational flexibility
• REACH compliance status documented for regulatory applications

For applications currently using the 2902956, direct replacement with the 2909525 is electrically and mechanically compatible without circuit modification or reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2909525 directly replace the 2902956 in existing installations?
