Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2980526 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be DC to ensure compatibility with the load circuit
• Voltage - Input: Must be 110VDC to match control signal requirements
• Voltage - Load: Must support 3V ~ 33V range to cover all intended load applications
• Load Current: Must support minimum 3A to handle specified load conditions
• Mounting Type: Must be DIN Rail to fit existing mechanical installations
• Package / Case: Must be Module format for form factor compatibility
• RoHS Compliance: Must maintain RoHS Compliant status for regulatory alignment

The Phoenix Contact 2900380 meets all these criteria and is identified as a direct substitute. The primary difference is the transition from spring terminal termination (2980526) to screw terminal termination (2900380) and the upgrade from obsolete to active product status within the PLC-OPT series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900380 is the direct substitute for the obsolete 2980526. Both components maintain identical electrical specifications across input voltage, load voltage range, and current capacity. The 2900380 offers the advantage of active product status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards.

The transition from spring terminal to screw terminal termination requires mechanical accommodation in the installation. Screw terminal connections provide enhanced reliability in industrial environments through positive mechanical locking, eliminating potential spring fatigue issues associated with spring terminal designs.

Both components maintain RoHS Compliance and are suitable for applications requiring DC solid-state relay functionality within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the 2900380 directly replace the 2980526 in existing installations?

A: Electrical compatibility is complete. Mechanical compatibility requires verification of the terminal connection interface. The 2980526 uses spring terminals while the 2900380 uses screw terminals. Installation procedures must be adapted accordingly.

Q: What is the significance of the series change from PLC to PLC-OPT?

A: The PLC-OPT series represents an active product line with ongoing manufacturer support. The PLC series (2980526) is obsolete and no longer manufactured. The PLC-OPT series maintains the same electrical functionality while providing modern manufacturing standards and availability.

Q: Are both parts RoHS Compliant?

A: Yes. Both the 2980526 and 2900380 are RoHS Compliant, meeting environmental and regulatory requirements for hazardous substance restrictions.

Q: What are the key parameters that must match for substitution?

A: Circuit configuration (SPST-NO), output type (DC), input voltage (110VDC), load voltage range (3V ~ 33V), load current (3A), mounting type (DIN Rail), and package format (Module) must all remain identical for functional substitution.

Q: Does the termination style change affect electrical performance?

A: No. Both spring and screw terminal styles provide equivalent electrical connectivity. The change affects installation methodology and mechanical reliability characteristics only.
