Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 2966537 is determined by strict equivalence across the following critical parameters:

• Contact configuration: SPDT (1 Form C)
• Contact current rating: 6 A minimum
• Coil voltage: 230VAC/DC
• Switching voltage capability: 250VAC, 250VDC minimum
• Mounting type: DIN Rail
• Coil type: Non Latching
• Termination style: Spring Terminal
• Contact material: Silver Tin Oxide (AgSnO)

The substitute part 2900305 meets all these criteria while offering improved product status and extended operating temperature range, making it a direct functional equivalent for the obsolete 2966537.

Parameter Comparison
