CD2425D3U Equivalent & Substitute Parts

Part Overview

The CD2425D3U is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual output channels in a hockey puck form factor. This component is rated for 25A load current with input voltage range of 4–15VDC and load voltage range of 24–280VAC, featuring zero-cross switching for AC applications.

The CD2425D3U is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Substitute Part Grouping Explanation

Substitution eligibility for the CD2425D3U is determined by strict alignment with the following electrical and mechanical parameters:

Circuit configuration: SPST-NO (1 Form A) x 2
Load current rating: 25 A
Load voltage range: 24–280 V
Output type: AC, Zero Cross
Package / Case: Hockey Puck
Termination style: Screw Terminal

Engineering Selection Recommendations

All three substitute parts—CD2425D2UH, CD2425W3U, and CC2425W3U—meet the core electrical and mechanical requirements for direct substitution with the obsolete CD2425D3U. The following factors apply to selection:

CD2425D2UH is the manufacturer-recommended substitute. It maintains the original 4–15VDC input voltage specification and is RoHS compliant with active product status.

CD2425W3U and CC2425W3U both feature an extended input voltage range of 4–32VDC, providing greater operational flexibility in systems with variable input supplies. Both are RoHS compliant and actively manufactured. CC2425W3U is supplied in bulk packaging, while CD2425W3U is supplied in standard packaging.

All substitute parts carry identical ECCN (EAR99) and HTSUS (8536.41.0060) classifications, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can CD2425W3U or CC2425W3U be used as direct replacements for CD2425D3U?

A: Yes. Both parts maintain identical circuit configuration, load current rating, load voltage range, output type, package form factor, and termination style. The extended input voltage range (4–32VDC versus 4–15VDC) does not prevent substitution; it expands operational capability.

Q: What is the difference between CD2425W3U and CC2425W3U?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: CD2425W3U is supplied in standard packaging, while CC2425W3U is supplied in bulk packaging. Selection depends on procurement and inventory requirements.

Q: Is the input voltage range difference between CD2425D2UH and CD2425W3U/CC2425W3U significant?

A: The input voltage range difference reflects design variations within the Evolution Dual series. CD2425D2UH maintains the original 4–15VDC specification. CD2425W3U and CC2425W3U support 4–32VDC input. Selection should be based on the actual input voltage supply in the target application. All three parts are functionally compatible with the CD2425D3U load-side circuit.

Q: Are all substitute parts RoHS compliant?

A: Yes. CD2425D2UH, CD2425W3U, and CC2425W3U are all RoHS compliant. The original CD2425D3U RoHS status was not specified in available documentation.

Q: What is the inventory status of substitute parts?

A: CD2425D2UH: 664 units in stock. CD2425W3U: 1,058 units in stock. CC2425W3U: 695 units in stock. All substitute parts are currently available.
