Phoenix Contact 2980649 SSR Relay - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2980649 is a solid-state relay (SSR) module configured as SPST-NO (1 Form A) with a 500 mA load capacity and input voltage of 24VDC. This module is designed for DIN rail mounting and operates with load voltages ranging from 3V to 48V DC. The product is classified as obsolete, making identification of suitable substitute components essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2980649 is determined by the following critical parameters:

• Input Voltage Compatibility: 24VDC control signal requirement
• Load Voltage Range: 3V to 48V DC operation capability
• Load Current Rating: Minimum 500 mA capacity
• Output Configuration: DC switching capability
• Mounting Standard: DIN rail compatibility
• Regulatory Compliance: RoHS compliance status

The substitute part Phoenix Contact 2900378 maintains compatibility across all critical electrical parameters (input voltage, load voltage range, and load current rating) and mounting standard. However, the circuit configuration differs from SPST-NO to SPDT, and the termination style changes from spring terminal to screw terminal. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900378 serves as a functional substitute for the obsolete 2980649 based on electrical parameter alignment. Both components share identical input voltage (24VDC), load voltage range (3V to 48V), load current capacity (500 mA), and DIN rail mounting compatibility.

The 2900378 holds active product status, ensuring ongoing availability and support, whereas the 2980649 is obsolete. The 2900378 carries ROHS3 compliance, representing current regulatory standards compared to the RoHS compliance of the original part.

Two design considerations apply to substitution:

1. Circuit Configuration Change: The 2900378 provides SPDT (1 Form C) switching versus the SPST-NO (1 Form A) configuration of the 2980649. Applications requiring only single-pole, single-throw operation can utilize the SPDT configuration by connecting only the required contacts. Applications requiring the additional switching capability benefit from the expanded contact arrangement.

2. Termination Interface: The 2900378 uses screw terminal connections instead of spring terminals. This requires modification to the connection interface and may necessitate rewiring or adapter considerations in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the 2900378 directly replace the 2980649 in existing installations?

A: Electrical compatibility is confirmed across all critical parameters. Physical installation requires evaluation of the termination style change from spring terminal to screw terminal and potential modifications to the connection interface.

Q: What is the significance of the circuit configuration difference between SPST-NO and SPDT?

A: SPST-NO (Single Pole Single Throw Normally Open) provides one switching contact. SPDT (Single Pole Double Throw) provides two switching contacts with a common terminal. Applications requiring only single-contact switching can utilize the SPDT configuration by connecting to the appropriate contact pair. The additional contact arrangement does not prevent substitution in SPST-NO applications.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 2900378 carries ROHS3 compliance, representing current regulatory standards. The 2900378 is also REACH Affected, indicating compliance with additional chemical substance regulations.

Q: Why is the 2980649 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2900378, with active product status, represents the current equivalent offering from Phoenix Contact for this functional category.

Q: What packaging differences exist between these parts?

A: The 2980649 is supplied in standard packaging, while the 2900378 is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact electrical or mechanical compatibility.
