Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2912293 is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (48VDC)
• Contact configuration (SPDT / 1 Form C)
• Current rating (10A minimum)
• Switching voltage capability (250VAC, 250VDC maximum)
• Mounting interface (DIN Rail)
• Coil current draw (20 mA)
• Termination method (Spring Terminal)
• Operating temperature range (-40°C ~ 60°C)
• Contact material composition (Silver Nickel)

The Phoenix Contact 2900294 meets all substitution criteria as a direct equivalent component within the Phoenix Contact product family, offering identical electrical and mechanical specifications with the additional feature of integrated coil protection diode.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900294 is the direct substitute for the obsolete 2912293. Both components are RoHS compliant and carry identical electrical and mechanical specifications across all critical parameters. The 2900294 is currently in active production status, ensuring long-term availability and supply chain continuity.

The 2900294 includes an integrated coil protection diode as an additional feature not present in the original 2912293. This diode provides transient suppression during coil de-energization, which may improve system reliability in applications with inductive switching loads. The coil resistance specification of 2.4 kOhms for the 2900294 aligns with the 20 mA coil current requirement at 48VDC.

Both components utilize identical DIN rail mounting interfaces and spring terminal connections, enabling direct mechanical and electrical substitution without modification to existing installation hardware or wiring practices.
