Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2980872 is determined by 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 compatible load switching characteristics
• Input Voltage: Must be 120VAC to match control signal requirements
• Load Voltage Range: Must support 12V ~ 300V to cover all application scenarios
• Load Current: Must be rated for 1A minimum to handle specified loads
• Mounting Type: Must be DIN Rail to ensure mechanical compatibility with existing installations
• Package Type: Must be Module format for form-factor compatibility

The Phoenix Contact 2900388 meets all these criteria and is therefore a direct functional equivalent. The primary distinction is the termination style (screw terminal versus spring terminal) and product status (active versus obsolete), with the 2900388 offering continued availability and supply assurance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900388 is the direct substitute for the obsolete 2980872. Both components share identical electrical specifications across all critical parameters: circuit configuration, voltage ratings, current capacity, and output type. The 2900388 is classified as active product status, ensuring ongoing availability and supply chain continuity.

The termination style difference (spring terminal on 2980872 versus screw terminal on 2900388) represents the only mechanical distinction. This change requires evaluation within the context of the specific installation: spring terminals provide tool-free connection suitable for rapid assembly, while screw terminals offer enhanced mechanical security and are standard in industrial control applications. Both termination methods are compatible with DIN rail module form factors.

RoHS compliance is maintained across both parts, satisfying environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900388 directly replace the 2980872 in existing installations?

A: The 2900388 is electrically and mechanically compatible as a direct substitute. The termination style difference (screw terminal versus spring terminal) requires assessment of the connection method used in the existing installation. If the original installation uses spring terminal connections, terminal block adapters or rewiring may be necessary.

Q: What is the significance of the product status change from obsolete to active?

A: The 2980872 is classified as obsolete, indicating Phoenix Contact no longer manufactures or supports this part. The 2900388 is active product, meaning it is currently manufactured and available through authorized distributors. This ensures long-term supply availability and access to technical support.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both the 2980872 and 2900388 share identical electrical specifications: 120VAC input, 12V to 300V DC load voltage range, 1A load current capacity, SPST-NO circuit configuration, and DC output type. These parameters determine functional equivalence in switching applications.

Q: What is the difference between spring terminal and screw terminal connections?

A: Spring terminals allow tool-free insertion and removal of conductors, suitable for applications requiring frequent reconfiguration. Screw terminals require a screwdriver for connection but provide enhanced mechanical security and are standard in permanent industrial installations. Both are compatible with DIN rail module mounting.

Q: Does the series designation change affect compatibility?

A: The 2980872 belongs to the PLC series, while the 2900388 belongs to the PLC-OPT series. This designation reflects product line evolution within Phoenix Contact's portfolio. The series change does not affect electrical or mechanical compatibility; it indicates the 2900388 represents the current generation equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2980872 and 2900388 are RoHS compliant, meeting environmental and regulatory requirements for hazardous substance restrictions in electrical and electronic equipment.
