Phoenix Contact 2902963 SSR Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2902963 is a solid-state relay (SSR) module configured as SPST-NO (Single Pole Single Throw - Normally Open) with a 1 Form A circuit. This component is designed for DIN rail mounting and operates with a 5VDC input signal to control DC loads between 4V and 30V at 50mA maximum current. The 2902963 is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2902963 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 5VDC
• Load current rating must be 50 mA minimum
• Mounting type must be DIN Rail
• Termination style must be Screw Terminal
• Package type must be Module

The Phoenix Contact 2902967 qualifies as a direct substitute based on these criteria. The primary difference between the two components is the load voltage operating range: the 2902963 operates from 4V to 30V, while the 2902967 operates from 14V to 30V. This difference represents a narrower minimum voltage threshold on the substitute part, which does not prevent substitution in applications where the load voltage remains within the 14V to 30V range.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2902967 is the qualified substitute for the obsolete 2902963 component. The 2902967 maintains identical electrical specifications for input voltage (5VDC), load current (50mA), circuit configuration (SPST-NO), and output type (DC). Both components share the same mounting type (DIN Rail), termination style (Screw Terminal), and package type (Module).

The 2902967 carries Active product status, ensuring continued availability and supply chain support. The component meets ROHS3 compliance and is REACH Affected, representing current regulatory alignment. The narrower load voltage range (14V to 30V versus 4V to 30V) on the substitute part requires verification that the application load voltage does not fall below 14V.

Frequently Asked Questions (FAQ)

Q: Can the 2902967 directly replace the 2902963 in all applications?

A: The 2902967 is a direct substitute provided the load voltage in your application operates within the 14V to 30V range. If your application requires operation below 14V, the 2902967 is not suitable.

Q: What is the primary difference between these two parts?

A: The load voltage operating range differs. The 2902963 operates from 4V to 30V, while the 2902967 operates from 14V to 30V. All other electrical and mechanical specifications are identical.

Q: Why is the 2902963 listed as obsolete?

A: The 2902963 has been discontinued by Phoenix Contact. The 2902967 represents the current active alternative within the PLC-OSC series.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The 2902967 meets ROHS3 compliance and is REACH Affected, reflecting current regulatory requirements. The 2902963 is RoHS Compliant without additional REACH designation.

Q: Do both parts use the same mounting and termination methods?

A: Yes. Both the 2902963 and 2902967 mount on DIN rail and use screw terminal connections, ensuring mechanical and electrical compatibility in existing installations.

Q: What is the load current capacity for both parts?

A: Both the 2902963 and 2902967 are rated for 50mA maximum load current at the specified voltage ranges.
