CD2425W3UR Equivalent & Substitute Parts

Part Overview

The CD2425W3UR 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 rated load current of 25A and load voltage range of 24V to 280V, controlled by a 4-32VDC input signal. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD2425W3UR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 dual relay arrangement
• Load current rating: 25A minimum
• Load voltage range: 24V to 280V AC
• Input control voltage: 4-32VDC
• Package type: Hockey Puck form factor
• Termination: Screw Terminal
• Mounting: Chassis Mount

The CC2425W3U from Sensata-Crydom meets all these requirements and is classified as an active product, making it a direct functional equivalent for the obsolete CD2425W3UR.

Parameter Comparison

Engineering Selection Recommendations

The CC2425W3U is the direct substitute for the CD2425W3UR. Both components share identical electrical specifications across all critical parameters: dual SPST-NO configuration, 25A load current, 24-280V AC load voltage range, and 4-32VDC control input. The CC2425W3U is manufactured by Sensata-Crydom (part of the same Sensata Technologies group) and maintains active product status with RoHS compliance certification. The Hockey Puck package and screw terminal configuration ensure mechanical and electrical compatibility in existing applications. The CC2425W3U includes zero-cross switching capability, which provides enhanced performance characteristics for AC load control without compromising backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CC2425W3U directly replace the CD2425W3UR in existing applications?

A: Yes. Both components have identical circuit configurations (SPST-NO x 2), load current ratings (25A), load voltage ranges (24-280V AC), input control voltages (4-32VDC), package types (Hockey Puck), and termination styles (Screw Terminal). Physical and electrical compatibility is confirmed.

Q: What is the difference between the AC output type and AC with Zero Cross output type?

A: The CC2425W3U includes zero-cross switching, which synchronizes relay switching to the AC voltage zero-crossing point. This reduces electromagnetic interference and switching noise compared to standard AC switching. This enhancement does not affect compatibility with the CD2425W3UR application requirements.

Q: Are there any compliance differences between the two parts?

A: The CC2425W3U is certified as RoHS Compliant. The CD2425W3UR compliance status was not specified in the available data. Both components share the same ECCN (EAR99) and HTSUS (8536.41.0060) classifications.

Q: Why is the CD2425W3UR classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The CC2425W3U is the active equivalent and is recommended for new designs and component replacement applications.

Q: Are packaging options different between these parts?

A: The CD2425W3UR was available in standard packaging. The CC2425W3U is supplied in Bulk packaging. Both maintain the Hockey Puck form factor and screw terminal configuration required for chassis mount applications.
