Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2954390 is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be DC to ensure compatibility with the load circuit
• Input Voltage: Must support 24 VDC control signal
• Load Current Rating: Must support minimum 500 mA continuous operation
• Mounting Type: Must support DIN rail installation for mechanical compatibility
• Termination Style: Must use screw terminals for connection compatibility
• Package Type: Must be a module format

The substitute part Phoenix Contact 2980636 meets all these criteria. While the load voltage range differs (3 V ~ 48 V versus 22 V ~ 35 V), the 2980636 encompasses the original voltage specification, making it functionally compatible for applications requiring the 22 V to 35 V range. The 2980636 is an active product with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2980636 is the direct substitute for the obsolete 2954390. Both components share identical circuit configuration, input voltage, load current rating, mounting type, and termination style. The 2980636 provides an expanded load voltage range that fully encompasses the original specification.

The 2980636 offers additional advantages: it maintains active product status, ensuring long-term availability and support; it meets ROHS3 compliance, representing current regulatory standards; and it includes REACH compliance documentation. The component is available in bulk packaging and maintains the same moisture sensitivity classification.

For applications currently using the 2954390, direct replacement with the 2980636 is supported without circuit modification or redesign.

Frequently Asked Questions (FAQ)
