CD2450W2V Equivalent & Substitute Parts

Part Overview

The CD2450W2V is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual Form A circuits. This active product is designed for chassis mount applications with a hockey puck package form factor. The device handles 50A load current across a 24V to 280V AC range with zero-cross switching capability. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2450W2V is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) x 2 dual configuration
• Load Current Rating: Must be rated for 50A
• Load Voltage Range: Must support 24V to 280V AC operation
• Output Type: Must feature AC output with zero-cross switching
• Mounting Type: Must be chassis mount compatible
• Termination Style: Must use screw terminal connections

The ASR-SID240D50ZL-S meets these core substitution criteria. However, the input voltage range differs: the substitute accepts 4 ~ 15VDC compared to the main part's 4 ~ 32VDC specification. This represents a narrower input voltage window and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CD2450W2V and ASR-SID240D50ZL-S are active products with current manufacturing status. The CD2450W2V maintains RoHS compliance, while the ASR-SID240D50ZL-S achieves ROHS3 compliance, indicating alignment with current regulatory standards.

The primary technical distinction is the input voltage specification. The CD2450W2V accepts 4 ~ 32VDC, whereas the ASR-SID240D50ZL-S operates within 4 ~ 15VDC. Selection between these parts must be based on the control circuit voltage available in the application. If the control voltage exceeds 15VDC, the substitute part is not suitable. If the control voltage remains within the 4 ~ 15VDC window, both parts are electrically equivalent for load switching purposes.

The package form factor differs: the main part uses a hockey puck configuration while the substitute uses a module package. This difference may affect mechanical fit and thermal management characteristics in the application enclosure.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SID240D50ZL-S replace the CD2450W2V in all applications?

A: Electrical substitution is possible only when the control circuit voltage remains within 4 ~ 15VDC. If your application requires input voltages above 15VDC, the substitute part cannot be used. Mechanical fit must also be verified due to the different package form factors (hockey puck versus module).

Q: What is the significance of the different package types?

A: The CD2450W2V uses a hockey puck package while the ASR-SID240D50ZL-S uses a module package. These represent different physical form factors and mounting footprints. Mechanical compatibility with the application's enclosure and thermal management design must be confirmed before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The CD2450W2V is RoHS Compliant, and the ASR-SID240D50ZL-S is ROHS3 Compliant. Both meet current environmental and regulatory requirements.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must remain identical: circuit configuration (SPST-NO x 2), load current rating (50A), load voltage range (24V ~ 280V AC), output type (AC with zero-cross), mounting type (chassis mount), and termination style (screw terminal).

Q: How does the input voltage difference affect substitution decisions?

A: The input voltage specification defines the control signal range required to operate the relay. The CD2450W2V accepts 4 ~ 32VDC, providing broader compatibility with various control circuits. The ASR-SID240D50ZL-S accepts only 4 ~ 15VDC. Substitution is valid only if your control voltage naturally falls within the 4 ~ 15VDC range.
