Phoenix Contact 2905080 SSR Relay - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2905080 is a solid-state relay (SSR) module configured as SPST-NO (1 Form A) with 1A load capacity and input voltage of 230VAC. This component is designed for switching DC loads in the 12V to 60V range. The product is currently classified as obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2905080 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be DC
• Input voltage must be 230VAC
• Load current rating must be 1A minimum
• Load voltage range must encompass or exceed the original 12V ~ 60V specification
• RoHS compliance status must be maintained

The Phoenix Contact 2900389 qualifies as a functional substitute based on these criteria. Both components share identical circuit topology, input voltage, load current rating, and RoHS compliance. The primary differences are load voltage range capability (extended to 300V), mounting configuration (DIN Rail vs. Socketable), and termination style (Screw Terminal vs. Plug In).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900389 is an active product with current manufacturer support, addressing the obsolescence status of the 2905080. Both components maintain RoHS compliance and identical electrical switching characteristics for the specified load current and input voltage.

Selection between these components depends on system integration requirements. The 2905080 socketable mounting and plug-in termination are specific to legacy system designs. The 2900389 DIN Rail mounting and screw terminal configuration represent current industrial standard practices and provide extended load voltage capability (12V ~ 300V) compared to the original 60V maximum.

For applications requiring the original socketable form factor, the 2905080 remains the specified component. For new designs or system upgrades, the 2900389 offers active product status and broader voltage compatibility within the same electrical performance envelope.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900389 directly replace the 2905080 in existing installations?

A: Electrical substitution is valid based on identical circuit configuration, input voltage, and load current rating. Physical installation requires verification of mounting compatibility. The 2905080 uses socketable mounting with plug-in termination, while the 2900389 requires DIN Rail mounting with screw terminal connections. Mechanical adaptation may be necessary.

Q: What is the significance of the extended load voltage range in the 2900389?

A: The 2900389 supports load voltages up to 300V compared to the 2905080 maximum of 60V. This extended range does not affect applications operating within the original 12V ~ 60V specification. The component remains fully compatible for these voltage levels.

Q: Why is the 2905080 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2900389 represents the current active product line from Phoenix Contact for equivalent SPST-NO solid-state relay functionality with 230VAC input and 1A load current.

Q: Are both components RoHS compliant?

A: Yes. Both the 2905080 and 2900389 maintain RoHS compliance status, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What are the key differences in termination between these components?

A: The 2905080 uses plug-in termination suitable for socketable mounting applications. The 2900389 uses screw terminal connections designed for DIN Rail installation. These differences require corresponding changes to the system interconnection method.
