Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900306 is the direct substitute for the obsolete 2966540. The 2900306 is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain identical electrical specifications and mechanical form factors required for DIN rail installation.

The 2900306 offers an extended operating temperature range (-40°C to 60°C versus -25°C to 60°C), providing broader environmental compatibility. The contact material composition differs slightly, with the 2900306 utilizing Silver Tin Oxide (AgSnO) in place of pure Silver (Ag), while both retain Gold (Au) plating. The 2900306 carries ROHS3 compliance certification, meeting current regulatory requirements, and includes REACH Affected status documentation.

For applications currently using the 2966540, direct replacement with the 2900306 is supported by matching coil voltage, contact configuration, current ratings, switching specifications, and response times. No circuit modifications or additional qualification is required.

Frequently Asked Questions (FAQ)
