CD2450E2U Equivalent & Substitute Parts

Part Overview

The CD2450E2U is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual relay module in a hockey puck package. This component is designed for AC load switching applications with a 50A capacity across a 24V to 280V load voltage range, controlled by a 15V to 32VDC input signal. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD2450E2U is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 dual relay architecture
• Load current rating: 50A minimum
• Load voltage range: 24V to 280V AC
• Output type: AC with zero-cross switching
• Input control voltage: Compatible with 15V to 32VDC range
• Package form factor: Hockey puck chassis mount
• Termination: Screw terminal connections

The CD2450W2U meets all these criteria and is identified as a direct substitute. The substitute part maintains identical electrical specifications for load handling and switching characteristics while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CD2450W2U is the appropriate substitute for the obsolete CD2450E2U. Both components share identical load handling specifications (50A at 24V to 280V AC) and circuit architecture (dual SPST-NO configuration with zero-cross switching). The CD2450W2U offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the CD2450W2U carries RoHS compliance certification, meeting current environmental and regulatory standards. The expanded input voltage range (4V to 32VDC versus 15V to 32VDC) of the substitute part provides additional operational flexibility without compromising compatibility in applications designed for the original component.

Frequently Asked Questions (FAQ)

Q: Can the CD2450W2U directly replace the CD2450E2U in existing applications?

A: Yes. Both components maintain identical load current ratings (50A), load voltage specifications (24V to 280V AC), circuit configuration (dual SPST-NO), and package form factor (hockey puck chassis mount). The CD2450W2U input voltage range encompasses the CD2450E2U specification, ensuring full compatibility.

Q: What is the significance of the expanded input voltage range in the CD2450W2U?

A: The CD2450W2U accepts input control signals from 4VDC to 32VDC, compared to the CD2450E2U range of 15VDC to 32VDC. This broader range does not affect compatibility with existing designs but allows the substitute part to operate in applications with lower control voltage sources.

Q: Why is product status relevant to component selection?

A: The CD2450E2U is obsolete, indicating discontinued manufacturing and limited availability. The CD2450W2U is active, ensuring reliable procurement, technical support, and continued supply. For new designs or system maintenance requiring component replacement, the active substitute is the appropriate selection.

Q: Are there compliance differences between the two parts?

A: The CD2450W2U is certified RoHS compliant, meeting current environmental regulations for restricted substances. The CD2450E2U compliance status is not specified. For applications subject to RoHS requirements, the CD2450W2U is the required selection.

Q: Do the screw terminal connections require any modification during substitution?

A: No. Both components use identical screw terminal termination, allowing direct connection without modification to existing wiring or terminal blocks.
