Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2966511 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 60VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration
• Contact Rating: 6A minimum
• Switching Voltage: 250VAC, 250VDC maximum capability
• Mounting Type: DIN Rail
• Coil Type: Non Latching
• Operating Temperature Range: -40°C ~ 60°C minimum
• Contact Material: Silver Tin Oxide (AgSnO)
• Termination Style: Spring Terminal

The Phoenix Contact 2900303 meets all specified parameters for direct substitution. Both relays share identical electrical characteristics, contact ratings, and operational specifications. The primary distinction is product status: the 2966511 is obsolete while the 2900303 is active production.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900303 is the direct equivalent substitute for the obsolete 2966511. Both components are RoHS compliant and carry identical MSL ratings. The 2900303 is currently in active production status, ensuring availability for new designs and replacement applications.

Selection of the 2900303 is appropriate for any application previously specified with the 2966511, as all electrical and mechanical parameters are equivalent. The active production status of the 2900303 provides supply chain continuity and eliminates obsolescence risk associated with the 2966511.
