CD2425W1U Equivalent & Substitute Parts

Part Overview

The CD2425W1U is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) x 2 in Hockey Puck package configuration. This component is rated for 25A load current with input voltage range of 4–32VDC and output voltage range of 24–280V AC with zero-cross switching. The CD2425W1U is currently obsolete, necessitating identification of active equivalent and substitute parts to maintain system functionality and ensure continued component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2425W1U is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC, Zero Cross
• Voltage - Input: 4 ~ 32VDC (or compatible subset)
• Voltage - Load: 24 V ~ 280 V
• Load Current: 25 A
• Mounting Type: Chassis Mount
• Package / Case: Hockey Puck or Module

Substitute parts are grouped into two categories: direct Sensata-Crydom Evolution Dual series replacements (CC2425W1UH, CD2425W2U, CD2425W3U) and cross-manufacturer alternatives (ASR-SID240D25ZL). All listed substitutes maintain electrical equivalence across load voltage, load current, and circuit topology. Variations in input voltage range, termination style, and package form factor are noted where they occur.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete CD2425W1U, the following selection criteria apply:

Sensata-Crydom Evolution Dual Series (CC2425W1UH, CD2425W2U, CD2425W3U): These parts maintain full electrical and mechanical equivalence with the original CD2425W1U. All three are active products with RoHS compliance. CC2425W1UH is the direct successor with identical specifications. CD2425W2U and CD2425W3U are alternative variants within the same series, suitable for applications where the specific variant designation is not critical to system function. These options provide the highest compatibility with existing designs and mounting infrastructure.

Altran Magnetics ASR-SID240D25ZL: This cross-manufacturer substitute maintains electrical equivalence for load voltage, load current, and circuit topology. The input voltage range is restricted to 4–15VDC (versus 4–32VDC for Sensata-Crydom parts), which may limit applicability in systems requiring higher control voltage. Termination style differs (Quick Connect versus Screw Terminal) and package form is Module rather than Hockey Puck, requiring mechanical redesign. This option is suitable only when input voltage requirements fall within the 4–15VDC range and mechanical accommodation for Module packaging is feasible. ROHS3 compliance status exceeds RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can CC2425W1UH, CD2425W2U, and CD2425W3U be used interchangeably with CD2425W1U?

A: Yes. All three Sensata-Crydom substitutes maintain identical electrical specifications (input voltage 4–32VDC, load voltage 24–280V, 25A capacity, SPST-NO x 2 configuration, AC zero-cross output) and mechanical form factor (Hockey Puck, Chassis Mount, Screw Terminal). They are direct functional equivalents.

Q: What is the primary limitation of the ASR-SID240D25ZL substitute?

A: The ASR-SID240D25ZL has a restricted input voltage range of 4–15VDC compared to the CD2425W1U specification of 4–32VDC. Applications requiring control voltages above 15VDC cannot use this substitute. Additionally, the Quick Connect termination and Module package form require mechanical redesign compared to the Hockey Puck Screw Terminal configuration.

Q: Are all substitute parts RoHS compliant?

A: Yes. CC2425W1UH, CD2425W2U, and CD2425W3U are RoHS Compliant. ASR-SID240D25ZL is ROHS3 Compliant, which represents a higher compliance standard.

Q: Which substitute should be selected for a direct drop-in replacement?

A: CC2425W1UH is the direct successor to CD2425W1U within the Sensata-Crydom Evolution Dual series and requires no design modification. CD2425W2U and CD2425W3U are functionally equivalent alternatives within the same series. All three are suitable for direct replacement without mechanical or electrical redesign.

Q: Can the ASR-SID240D25ZL be used if the system control voltage is 24VDC?

A: No. The ASR-SID240D25ZL input voltage specification is 4–15VDC. A 24VDC control signal exceeds this range and will not operate the device. A Sensata-Crydom substitute (CC2425W1UH, CD2425W2U, or CD2425W3U) must be used for control voltages above 15VDC.
