Phoenix Contact 2903698 General Purpose Relay DPDT 24VDC

Part Overview

The Phoenix Contact 2903698 is a general purpose relay with DPDT (Double Pole Double Throw, 2 Form C) configuration, rated for 16A at 24VDC coil voltage. This socketable relay is designed for standard industrial control applications requiring dual-channel switching capability. The part is currently in stock with 619 units available as new original inventory.

Alternative models may be required when application specifications demand different contact configurations, such as increased switching channels or when managing component availability across supply chains.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903702 is identified as a substitute for the 2903698 based on the following substitution criteria:

Common Parameters:

• Manufacturer: Phoenix Contact
• Coil Voltage: 24VDC
• Current Rating: 16A
• Form Factor: Socketable
• Product Status: New Original

Differentiating Parameter:

• Contact Configuration: The 2903702 features 3PDT (3 Form C) configuration versus the 2 Form C configuration of the 2903698

Substitution is valid when applications require expanded switching capability from dual-channel (DPDT) to triple-channel (3PDT) operation while maintaining identical coil voltage, current rating, and socketable mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 2903698 and 2903702 is determined by the required number of independent switching channels:

• 2903698 (DPDT): Select when the application requires two independent Form C contacts for dual-channel switching operations.

• 2903702 (3PDT): Select when the application requires three independent Form C contacts for triple-channel switching operations.

Both relays maintain identical electrical specifications for coil voltage (24VDC) and contact current rating (16A), ensuring compatibility within the same control architecture. Both are available as new original stock from Phoenix Contact with socketable mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the 2903702 (3PDT) be used as a direct replacement for the 2903698 (DPDT)?

A: The 2903702 can be substituted when the application circuit design accommodates three Form C contacts instead of two. The additional contact channel does not create incompatibility if left unused, provided the socket and mounting space accommodate the different relay body dimensions.

Q: What is the primary difference between these two relay models?

A: The primary difference is the contact configuration. The 2903698 provides two independent switching channels (DPDT), while the 2903702 provides three independent switching channels (3PDT). All other electrical parameters—coil voltage, current rating, and socketable form factor—remain identical.

Q: Are both relays compatible with the same socket?

A: Both relays feature socketable form factors within the Phoenix Contact REL-PR series. However, verify socket compatibility with the specific socket model, as DPDT and 3PDT relays may have different pin configurations and physical dimensions.

Q: Which relay should be selected for new designs?

A: Selection depends on the number of independent switching channels required by the application. For dual-channel applications, the 2903698 is appropriate. For triple-channel applications, the 2903702 is appropriate. Both are equally suitable for new designs from an availability and specification standpoint.
