CD2450W4VR Equivalent & Substitute Parts

Part Overview

The CD2450W4VR is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) x 2 configuration in a hockey puck package. This component is rated for 50A load current with input voltage range of 4–32VDC and output voltage range of 24–280VAC. The part is currently obsolete, necessitating identification of active equivalent models that maintain electrical and mechanical compatibility for continued system operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2450W4VR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Load current rating: 50A
• Input voltage range: 4–32VDC
• Output voltage range: 24–280VAC
• Output type: AC
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

All identified substitute parts maintain these specifications. Variations in product status (active vs. obsolete), RoHS compliance, and zero-cross functionality do not affect electrical or mechanical interchangeability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (CC2450W4V, CD2450W1VR, CD2450W2VR) are electrically and mechanically equivalent to the CD2450W4VR within the defined parameter set. Selection among these alternatives should be based on:

• Product availability and lead time
• RoHS compliance requirements (all substitutes are RoHS Compliant)
• Packaging preference (CC2450W4V supplied in Bulk; CD2450W1VR and CD2450W2VR supplied as individual units)
• Zero-cross functionality requirement (CC2450W4V includes zero-cross switching; CD2450W1VR and CD2450W2VR do not)

All substitutes maintain active product status, ensuring continued manufacturer support and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can CC2450W4V replace CD2450W4VR directly?

A: Yes. CC2450W4V maintains all critical electrical parameters (50A, 4–32VDC input, 24–280VAC output, SPST-NO x 2 configuration) and mechanical specifications (hockey puck package, screw terminal, chassis mount). The addition of zero-cross functionality in CC2450W4V does not prevent direct substitution.

Q: What is the difference between CD2450W1VR and CD2450W2VR?

A: Both parts are electrically and mechanically identical within the specified parameter set. The manufacturer designation differs (Sensata-Crydom vs. Sensata Technologies), but both maintain the same electrical ratings, circuit configuration, and package type.

Q: Does the hockey puck package remain the same across all substitutes?

A: Yes. All substitute parts use the hockey puck package with screw terminal termination and chassis mount configuration, ensuring mechanical compatibility with existing installations.

Q: Are all substitutes RoHS Compliant?

A: Yes. CC2450W4V, CD2450W1VR, and CD2450W2VR are all RoHS Compliant. The original CD2450W4VR RoHS status was not specified.

Q: What does zero-cross functionality mean in CC2450W4V?

A: Zero-cross switching synchronizes relay activation with the AC voltage waveform zero-crossing point, reducing electromagnetic interference and switching stress. This feature does not affect electrical interchangeability with non-zero-cross variants.
